Greater Philadelphia

Civic boosters in the late nineteenth century adopted “Greater Philadelphia” as a phrase denoting aspirations for progress as well as way of describing the region including Philadelphia and extending beyond its boundaries. For more than a century since, numerous businesses and other organizations, including The Encyclopedia of Greater Philadelphia, have signaled their regional scope by adopting this phrase. This layer of the Encyclopedia emphasizes topics that cross the region of Philadelphia, southeastern Pennsylvania, South Jersey, and Delaware, including governance, geography and settlement patterns, infrastructure, transportation, and social issues.

Topics: Regional Connections and Impact

Abscam

Launched in March 1978, the FBI sting operation known as Abscam led to the conviction of a U.S. senator, six congressmen, three Philadelphia City Council members, and the mayor of Camden, New Jersey, for taking bribes from undercover agents pretending to be the Arab sheiks. The FBI secretly filmed the transactions in hotel rooms in ⇒ Read More

Admiral Wilson Boulevard

Admiral Wilson Boulevard, a two-and-a-half-mile section of U.S. Route 30 extending from the Benjamin Franklin Bridge in Camden to the Route 70 overpass in Pennsauken, was the first “auto strip” in the United States. Originally named Bridge Approach Boulevard when it opened in 1926, it was renamed in 1929 to honor Rear Admiral Henry Braid ⇒ Read More

African American Migration

People of African descent have migrated to Philadelphia since the seventeenth century. First arriving in bondage, either directly from Africa or by way of the Caribbean, they soon developed a small but robust community that grew throughout the eighteenth and nineteenth centuries. Although African Americans faced employment discrimination, disfranchisement, and periodic race riots in the ⇒ Read More

AIDS and AIDS Activism

Doctors in Philadelphia diagnosed the first local case of what would later become known as AIDS (Acquired Immune Deficiency Syndrome) in September 1981, just months after the Centers for Disease Control first reported mysterious outbreaks of pneumocystis pneumonia and Kaposi’s sarcoma among gay men in New York and Los Angeles that marked the beginning of ⇒ Read More

Airports

Commercial aviation grew dramatically in the United States in the twentieth century, and a number of airports in the Philadelphia area grew to become regional centers of the industry. There was nothing assured or inevitable about this growth, however. It depended on the efforts of local political leaders, investments by the aviation companies, and state ⇒ Read More

American Civil Liberties Union (ACLU)

The American Civil Liberties Union, a national legal organization dedicated to the defense and preservation of civil liberties in the United States, has been organized in the Philadelphia region since 1951, when chapters formed in Pennsylvania and New Jersey as part of a move toward establishing branches throughout the nation. Both chapters played a role ⇒ Read More

Appeal of Forty Thousand Citizens

The Appeal of Forty Thousand Citizens, Threatened with Disfranchisement, to the People of Philadelphia attempted to persuade Philadelphians to vote against the ratification of a new constitution for Pennsylvania in 1838 because the word “white” had been inserted prior to “freemen” as a qualification for voting. Written by African American leader Robert Purvis (1810-98), the ⇒ Read More

Armories

Armories served as military training and recruiting sites, arms depots, headquarters, and social clubs for the nation’s citizen-soldiers. Early armories in Philadelphia were simply rented spaces in commercial buildings. After the Civil War, permanent structures for the exclusive use of the Pennsylvania National Guard supplanted these ad hoc armories as business interests responded to labor ⇒ Read More

Art Colonies

Outside the urban core of Philadelphia, the picturesque rural landscape proved a significant draw to many artists in search of the purportedly simple, wholesome, and moral quality of countryside living. Whether planned and intentional or more organic and serendipitous, colonies like those in New Hope, Chadds Ford, and Rose Valley in Pennsylvania, and Arden and ⇒ Read More

Arts of Wharton Esherick

The unconventional artistic trajectory and prolific work of prominent Philadelphia-area artist and craftsman Wharton Esherick (1877–1970) have been claimed for and by multiple movements in the history of twentieth-century American art, from early-twentieth-century Arts and Crafts to postwar studio craft. Working across a wide variety of media, including printmaking, sculpture, furniture, and theatrical design, Esherick ⇒ Read More

Atlantic City

Before Disneyland, Atlantic City was the first great middle-class resort in the nation, especially the Philadelphia region. From its founding in the 1850s through the early decades of the twenty-first century, Atlantic City succeeded and failed based on its ability to make itself in the image of the American middle class. As the cultural tastes ⇒ Read More

Automobile Racing

Motorsports developed into a popular leisure activity in the Philadelphia area during the twentieth century. Originally an activity enjoyed by wealthy car owners, the advent of the Model T Ford allowed local technophiles to build their own race cars and compete in regional races. By mid-century, drivers raced at fairground horse tracks and purpose-built speedways ⇒ Read More

Automobiles

Since appearing in the 1890s, automobiles have in many ways shaped Greater Philadelphia’s history and geography. Initially a luxury item and later available on a massive scale, cars, while enhancing mobility, required billions of dollars in infrastructure, reordered the landscape of every town and city, and made indelible marks on the region’s architecture, culture, and ⇒ Read More

Automotive Manufacturing

Once a mainstay of Greater Philadelphia’s industrial might and a reflection of the socioeconomic transformations of the twentieth and early twenty-first centuries, the manufacturing of automobiles and related components provided mobility for millions, jobs for many thousands, and lifeblood for towns and cities. First appearing in the 1900s, flourishing during the interwar and postwar periods, ⇒ Read More

Bakeries and Bakers

Baking, one of the earliest businesses in Philadelphia, did not become a major part of the local economy until the late nineteenth century. It remained a viable industry throughout the region’s history, however, ranging from small neighborhood bakeries to large baking companies with national product distribution. Philadelphia supported several commercial bakers from the beginning. A ⇒ Read More

Bank of the United States (First)

Chartered in 1791 as part of the financial and economic reform plans of Alexander Hamilton (1755–1804), the first secretary of the Treasury, the first Bank of the United States played an instrumental role in establishing the nation’s credit.

Bank War

Conflict over renewing the charter of the Second Bank of the United States triggered the 1830s Bank War, waged between President Andrew Jackson (1767-1845) and bank president Nicholas Biddle (1786-1844). Operating from its Parthenon-style building on Chestnut Street between Fourth and Fifth Streets in Philadelphia, the bank served as a reliable depository for federal money ⇒ Read More

Banking

Greater Philadelphia’s banking roots go deeper than those of any region in the country. Philadelphia was the home of the first commercial bank (1782), the first national bank (1791), the first savings bank (1816), and the first savings and loan association (1831). Until the mid-1980s, celebrated local institutions such as First Pennsylvania, Girard, and Provident ⇒ Read More

Barbershops and Barbers

Throughout much of its modern American history, barbering has been derided as “servile” work, unfit for native-born, white citizens. As such, the profession has been dominated by marginalized groups. In the Philadelphia region, African Americans owned and operated the majority of barber shops during the eighteenth and early nineteenth centuries. Since then, waves of immigrant ⇒ Read More

Bartram’s Garden

Located on the west bank of the Schuylkill River, Bartram’s Garden, considered the oldest surviving botanic garden in North America, has served as a monument to the storied history of Philadelphia’s botanical endeavors and to the genius of John Bartram (1699–1777) and his descendants. Established as a family farm and garden by John Bartram in ⇒ Read More

Baseball: Negro Leagues

More than any other city, Philadelphia epitomized the significance of Negro League baseball in urban communities. For a remarkable eight decades, local fans consistently supported a series of black ball clubs whose successes generated racial pride and represented a triumph of African American institution-building. In Philadelphia, the first all-black baseball teams surfaced in the 1860s. ⇒ Read More

Baseball: Professional

From the time the game was created to its organization into a professional league, and from the first National League game ever played to some of the earliest World Series, the city of Philadelphia has played a prominent role in professional baseball history. Variations of the game of baseball became popular some three decades prior ⇒ Read More

Bicycles

Since the nineteenth century, bicycles have enamored the American public as tools of transportation, sport, exercise, and joy. The Philadelphia area has been intimately connected with the development of the two-wheeled, human-powered machine from its early appearance in North America to the adoption of bike-share programs and the blazing of interstate trail networks in the ⇒ Read More

Big 5

The Big 5, an association of Philadelphia-area college basketball programs that have competed locally while also belonging to different conferences, formed in 1955 among five universities: La Salle, Penn, Saint Joseph’s, Temple, and Villanova. Showcasing the basketball talent of the region, the round-robin doubleheaders between Big 5 teams have attracted raucous fans and produced intense ⇒ Read More

Blue Route

Famous for the many protracted conflicts that delayed its full construction for decades, Pennsylvania’s Mid-County Expressway, also referred to as the Veterans Memorial Highway and, more commonly, the “Blue Route,” is the southernmost section of Interstate 476. The expressway stretches through southern Montgomery and Delaware Counties, linking the Pennsylvania Turnpike interchange at Plymouth Meeting with ⇒ Read More

Boarding and Lodging Houses

Distinguished by its ubiquitous row houses and high rates of home ownership, Philadelphia has been long been known as a “city of homes.” But for much of its history, it also has been a city of boardinghouses. “Boarding” and “lodging” houses did not enter the local lexicon until the late eighteenth century, but the practice ⇒ Read More

Bootlegging

Bootleg liquor, produced illegally during Prohibition (1920-33), flowed into the Philadelphia region from a variety of sources, including overseas shipments, small home stills, large stills in urban factories and country barns, beer breweries, and manufacturers of industrial alcohol. Philadelphia’s location at the confluence of the Delaware and Schuylkill Rivers, just inland from the Atlantic Ocean, ⇒ Read More

Boxing and Boxers

For over one hundred years, Philadelphia neighborhoods, for better and worse, played a significant role in molding fighters. Over two dozen world boxing champions throughout various weight classes called Philadelphia home. Nearby communities such as Camden, New Jersey, and Easton, Pennsylvania, also produced world champions. Over time, Philadelphia-area boxing was supported by a wide network ⇒ Read More

Brickmaking and Brickmakers

The city of Philadelphia was built with bricks, giving it an appearance many neighborhoods retained into the twenty-first century. An abundance of local clay allowed brickmaking to flourish and bricks to become the one of the most important building materials in the region. Because it could be accomplished with just a few rudimentary tools, brickmaking ⇒ Read More

Bridgeton, New Jersey

Bridgeton, the governmental seat of Cumberland County, originated in the late seventeenth century as a fording place at the upper tidal reach of the Cohansey River, a tributary of the Delaware Bay. Located seven direct miles from the bay (though twenty by meandering river), and about forty miles south of Philadelphia, Bridgeton drew on water ⇒ Read More

Brownfields Redevelopment

First designated by the U.S. Environmental Protection Agency (EPA) in 1995, the polluted tracts of land known as “brownfields” resulted from Greater Philadelphia’s industrial heritage. For more than a century, manufacturers generated vast amounts of waste and runoff. After industry declined between the 1950s and the 1980s, acres of abandoned structures and soiled land remained. ⇒ Read More

Bucks County, Pennsylvania

Bucks County, one of three counties established in 1682 by William Penn (1644-1718), originally stretched northward along the Delaware River all the way to the Delaware Water Gap and westward past Allentown. Even after shrinking dramatically when Northampton and Lehigh Counties were carved from its territory in 1752, the county still encompassed multiple regions that ⇒ Read More

Buses

Beginning in the 1920s, the Philadelphia region’s independent transit companies added motorized buses (autobuses) to their networks. Superior in comfort to the horse-drawn omnibuses of the nineteenth century and with more range and versatility than electric trolleys, autobuses offered passengers easier means to traverse the metropolitan area. Prior to the internal combustion engine, mass transit ⇒ Read More

Byberry (Philadelphia State Hospital)

From the arrival of its first patients in 1911 to 1990, when the Commonwealth formally closed it down, the Philadelphia State Hospital, popularly known as Byberry, was the home for thousands of mental patients. In its early decades Byberry was controlled by the city, and from 1938 onward it was one of the several hundred ⇒ Read More

Camden, New Jersey

Incorporated in 1828 and named county seat of the newly formed Camden County when it separated from Gloucester County in 1844, Camden City long served as the heart of the South Jersey region directly across the Delaware River from Philadelphia. Besieged in the second half of the twentieth century by losses of population and economic ⇒ Read More

Canals

Canals transformed the economic and geographic scope of Greater Philadelphia in the first half of the nineteenth century. By providing a cheap and reliable mechanism for shipping goods, these complex technological systems funneled the products of broad hinterland regions to the Quaker City. Although canals delivered a wide variety of goods including farm products, lumber, ⇒ Read More

Casinos

In the late twentieth and early twenty-first centuries, casino gambling became an accepted public policy in Pennsylvania, New Jersey, and other states desperate to generate tax revenue and create jobs. But the gains often came with significant social and economic costs in Atlantic City, Philadelphia, and other communities in the region. Casinos began to open ⇒ Read More

Cathedral Basilica of Saints Peter and Paul

Established in 1846, the Cathedral Basilica of Saints Peter and Paul at Eighteenth and Race Streets became the principal church and center of Catholic life for the clergy and faithful of the Philadelphia archdiocese. During a turbulent era of immigration and anti-Catholic nativism, Bishop Francis Patrick Kenrick (1796-1863) desired a “common church of the whole ⇒ Read More

Cemeteries

Cemeteries have been integral features of the Philadelphia-area landscape since the earliest European settlements of the mid-1600s. Over the centuries, and in tandem with developments such as epidemics, immigration, industrialization, war, and suburbanization, the region’s cemeteries matured from small, private grave sites, potter’s fields, and church burial yards to rural cemeteries, national cemeteries, and memorial ⇒ Read More

Chemical Industry

Since the eighteenth century, chemical or chemical processing industries have been an important part of the economy of Philadelphia and the Delaware Valley region and have reflected larger trends in the industry. The earliest chemical companies manufactured products such as sulfuric acid and white lead pigments for local consumption, while other manufacturers, such as tanners, ⇒ Read More

Chester County, Pennsylvania

As one of the original counties established by William Penn (1644-1718), Chester County was only modestly influenced by Philadelphia in its early development because after 1789 it shared no border with the city. Although the Pennsylvania Railroad linked the county’s central valley to Philadelphia in the mid-nineteenth century, it remained a largely rural landscape whose ⇒ Read More

Chester, Pennsylvania

Located 30 miles down the Delaware River from Philadelphia, the small but once industrially mighty city of Chester emerged in the latter part of the twentieth century as but a shadow of its former prominence in the county and the region. The municipality’s fortunes shifted many times over the 334 years of its existence, evolving ⇒ Read More

Cholera

The cholera epidemics that struck Philadelphia in 1832, 1849, and 1866 provided a catalyst for transforming the health and hygiene standards of the city. Asiatic cholera, endemic to India, escaped the sub-continent in 1817. It reached Western Europe in 1831, and was carried to North America in 1832 aboard immigrant ships, breaking out in Philadelphia ⇒ Read More

City Beautiful Movement

Grounded in landscape and European architecture and shaped by the politics of the Progressive Era, the City Beautiful Movement emerged in reaction to the physical decay and social congestion that burdened America’s industrial centers at the turn of the twentieth century. Considered the “mother” of urban planning, its promoters and practitioners sought to reorder the ⇒ Read More

Civil Defense

Because of Greater Philadelphia’s position as a political, cultural, and economic hub, the region’s residents have often found their daily lives deeply affected by times of national crisis. Civil defense, generally defined as local voluntary programs designed to protect civilian life and property during times of conflict, has taken many forms: militia, home defense, civilian defense, ⇒ Read More

Classical Music

Classical music stands apart from vernacular (or “folk” music) and from “popular” music (in the form of simplified commercial entertainment) in its complexity of structure and high level of performance requirements. Philadelphia established a major position in American classical composition and performance in the early nineteenth century, and maintained that position through its premier professional ⇒ Read More

Co-Working Spaces

In the 2000s and 2010s, nearly thirty co-working spaces opened in the Philadelphia area.

These spaces were designed to foster a collaborative atmosphere, where clients could share innovations and resources. A ⇒ Read More

Coal

In the nineteenth century, Philadelphia banks and entrepreneurs played a pivotal role in facilitating the emergence of coal as the nation’s principal energy source for industry, transportation, and heating, by creating and financing the firms that first brought to market anthracite coal, mined exclusively in rugged eastern Pennsylvania. To mine anthracite, or “hard coal,” on ⇒ Read More

Coffeehouses

Philadelphia’s first coffeehouse opened in 1703, and by mid-century half a dozen operated within the city limits. Their purpose, however, changed in important ways as the eighteenth century progressed. Early coffeehouses primarily served the needs of traders and mariners, acting as crucial centers of commerce. In the decades following the American Revolution, however, some coffeehouse ⇒ Read More

Cold War

The period of international political and military tension known as the Cold War (1947-91) had military, political, and cultural implications for Greater Philadelphia. The region served as a first line of defense for a conflict that depended more on missiles than forts, and it provided the nation with an arsenal, a shipyard, and a source ⇒ Read More

Colonization Movement (Africa)

The African colonization movement, dedicated to resettling North American free blacks in West Africa, caused heated debates in Philadelphia in the early nineteenth century. Proposals to remove free blacks from North America date from the 1770s, but the heyday of African colonization occurred between 1818 and 1865. Often described as a “return to Africa,” the ⇒ Read More

Columbus Day

Observed on the second Monday in October, Columbus Day in the Philadelphia region gained prominence as Italian immigrant communities grew in the late nineteenth and early twentieth century. By commemorating the 1492 arrival of Christopher Columbus (1451-1506) in the New World, Italian-Americans embraced the navigator as their countryman, celebrated Italian culture, and called attention to ⇒ Read More

Community Colleges

Two-year, public colleges—commonly known as community colleges—first appeared in the United States at the beginning of the twentieth century. Situated at the intersection of secondary and higher education, they were local institutions that offered both general studies and vocational training. Referred to as junior colleges before the 1950s, they owed their inspiration to Benjamin Franklin ⇒ Read More

Community Development Corporations (CDCs)

Community development corporations (CDCs), initially a federal initiative intended to direct resources to beleaguered neighborhoods where local activists would take the lead in identifying and solving their most pressing problems, first formed in Philadelphia at the end of the 1960s and early 1970s. As federal funding for such efforts dried up in the Reagan era, ⇒ Read More

Commuter Trains

Commuter trains have helped to shape and define Philadelphia and its region since their introduction in 1832. The trains influenced suburban development and shaped Center City. For most of this period, the trains charged higher fares than other forms of public transit and remained a largely middle-class means of transport. Commuter trains connected middle-class homes ⇒ Read More

Consolidation Act of 1854

The Consolidation Act of 1854 extended Philadelphia’s territory from the two-square-mile “city proper” founded by William Penn to nearly 130 square miles, making the municipal borders coterminous with Philadelphia County and turning the metropolis into the largest in extent in the nation, a position it held until Chicago leapt ahead in 1889. Consolidation’s supporters believed ⇒ Read More

Convents

Convents—communities of women devoted to religious life—in the Greater Philadelphia area played a significant role in the education of youth and in social services for communities from the nineteenth century into the twenty-first century. Although some regional Catholic convents moved or closed during this time, the Philadelphia area remained strong in Catholic identity because of ⇒ Read More

Country Clubs

Country clubs originated in the 1890s as elite, family-oriented havens usually emphasizing golf, but they have never been just about golf or even sports. Clubs fostered sportsmanship, appropriate deportment, and social development while also providing opportunities for exercise. A “golden age” of country clubs lasted until the Great Depression of the 1930s, and the number ⇒ Read More

Cricket

The rise, fall, and rebirth of the sport of cricket in the Philadelphia region reflected political, social, and economic change. Cricket once flourished in the city, which produced some legendary players known throughout the cricketing world. The rise of other leisure activities supplanted the game, however, until a moderate resurgence in the late twentieth and ⇒ Read More

Crime

Crime is inextricably linked to Philadelphia’s shifting economic fortunes. Its history reflects the region’s status as a port and point of entry for goods, immigrants, and migrants, where concentrations of both wealth and poverty developed in a center of American commerce and industry. As a type of economic activity, forms of crime changed dramatically as ⇒ Read More

Crowds (Colonial and Revolution Eras)

Social and economic elites dominated formal politics in Pennsylvania and New Jersey during the colonial and revolutionary eras, but ordinary people, often those who were ineligible to vote, helped shape the political culture. To support or oppose economic conditions and policies imposed by imperial, provincial, and local legislators, they periodically engaged in public celebrations, civil ⇒ Read More

Cycling (Sport)

The Philadelphia area’s connections to the sport of cycling have spanned nearly 200 years, reflecting its rise, decline, and resurgence in the United States. The region’s history of road, track, and all-terrain races began before the invention of the modern “bicycle” and continued into the twenty-first century with new variations of the sport and the ⇒ Read More

Deindustrialization

The Philadelphia region’s long-held reputation as the “workshop of the world,” though richly deserved, did not prevent it from suffering the same loss of manufacturing firms and jobs that devastated the economies of other manufacturing centers. Local products ranged widely, from locomotives and ships to silk hosiery, wool carpets, machine tools, hand tools, lighting fixtures, ⇒ Read More

Delaware Avenue (Columbus Boulevard)

Delaware Avenue, the north-south thoroughfare closest to the Delaware River in Philadelphia, owes its existence to the richest man in America, who wanted a grand avenue along the central waterfront. The street, including a portion renamed Columbus Boulevard in the 1990s, played a significant role in the development of Philadelphia’s maritime activity, particularly food distribution ⇒ Read More

Delaware Bay

The Delaware Bay does not often get the historical acknowledgement received by its estuarine neighbor, the Delaware River, but it exerted equal weight in shaping the Philadelphia region’s cultural and economic development. Over seven hundred square miles in size and bordered by New Jersey and Delaware, the Delaware Bay is one of America’s premier maritime ⇒ Read More

Delaware County, Pennsylvania

Carved out of Chester County in 1789 (with the remainder of that county lying to its southwest), Delaware County long served as a distinct but close neighbor to the City of Philadelphia. Linked to the Philadelphia port from the eighteenth century onward, the eastern part of the county, including Chester and its neighboring municipalities along ⇒ Read More

Delaware River Basin Commission

The four-state compact that established the Delaware River Basin Commission was a breakthrough innovation in addressing the interrelated land and water impacts of natural resources spanning political jurisdictions. For the first time, the federal government and several states joined as equal partners in a single agency to regulate and develop the watershed of an entire ⇒ Read More

Delaware River Port Authority

The Delaware River Port Authority (DRPA) was created nearly one hundred years ago as a bi-state commission for the purpose of building a single toll bridge.

Delaware Valley Regional Planning Commission

The Delaware Valley Regional Planning Commission (DVRPC) was founded in 1965 to coordinate planning activities within a nine-county area, which included Philadelphia, Bucks, Chester, and Delaware Counties in Pennsylvania and Camden, Burlington, Gloucester, and Mercer Counties in New Jersey. In the decades since its founding, DVRPC has worked to foster economic development, direct transportation projects, ⇒ Read More

Department Stores

As department stores became central to retailing in American cities in the late nineteenth and early twentieth centuries, Philadelphia played a major role. Led by John Wanamaker, whose store was a national model, Market Street became home to the giant stores known as the “Big Six,” which were close to rail terminals and subway stations. ⇒ Read More

Diners

With its origins in late-nineteenth-century street vending and transient “quick lunch” operations such as horse-drawn food carts, the diner emerged as one of the most popular and successful restaurant genres in the United States. Although diners entered a period of protracted decline after World War II with the arrival of fast food restaurants, changing consumer ⇒ Read More

Dispensaries

Free clinics known as dispensaries served the “working poor” of European, British, and American cities from the eighteenth through the early twentieth centuries. Paid or volunteer physicians saw patients on site or at their homes in the dispensary’s district, caring for both minor ailments and more serious diseases. The Philadelphia Dispensary for the Medical Relief ⇒ Read More

Dogfighting

The cruel practice of dogfighting has thrived in the shadows of the Philadelphia region for more than 150 years. Most commonly, young men have matched dogs against one another in remote locations and blighted neighborhoods for money and bragging rights. The process of training and culling weak dogs as well as the fights themselves have ⇒ Read More

Dogs

For as long as people have inhabited Philadelphia and the surrounding area, dogs probably have been present, too. As the first domesticated animal, dogs possess a long, complicated past with humans, likely dating back between fifteen thousand and thirty thousand years. Domesticated canids accompanied human migrants to the Americas around 10,000 to 12,000 BCE. Over ⇒ Read More

Doylestown, Pennsylvania

Located a mile north of the Routes 611-202 convergence, thirty-five miles north of Center City Philadelphia, Doylestown has served as the government center of Bucks County for over two centuries.

Dutch (The) and The Netherlands

From seventeenth-century Dutch settlements in the Delaware Valley to twenty-first century business connections, the greater Philadelphia area has had longstanding and meaningful ties with the Netherlands. Not to be confused with the more numerous Pennsylvania Dutch—who are in fact German, or Deutsch, speakers—Nederlanders helped shape Philadelphia through migration and cultural, social, and economic exchange. The ⇒ Read More

Edge Cities

Edge cities, as they came to be called, emerged on the peripheries of older urban centers in the last part of the twentieth century. As defined by journalist Joel Garreau (b. 1948), they contained at least five million square feet of leasable office space, 600,000 (or more) square feet of leasable retail space, “more jobs ⇒ Read More

Education and Opportunity

In the twentieth century, many urban school districts, which had been among the finest in the nation, became some of the most challenged. The Greater Philadelphia region reflected this trend. In 1900 the region’s school systems consisted of largely uncoordinated public, parochial, and private schools. Between 1900 and 1965 politicians, educational administrators, and civic leaders ⇒ Read More

Educational Reform

Since the early nineteenth century, several reform efforts have aimed to improve Philadelphia-area public schools. While the historical context and the individual actors changed over time, a firm belief that basic education for all could foster social equality animated reform in every era. Of course, race- and class-based inequality did not disappear, but educational reform ⇒ Read More

ENIAC

Developed in Philadelphia during World War II, the Electronic Numerical Integrator and Computer (ENIAC) made history as the world’s first general-purpose, nonmechanical computer. Unveiled at the University of Pennsylvania’s Moore School of Electrical Engineering in 1946, the ENIAC consisted of 40 nine-foot-high cabinets containing 18,000 vacuum tubes, 10,000 capacitors, 6,000 switches, and 1,500 relays. Unlike ⇒ Read More

Entomology (Study of Insects)

Philadelphia and its nearby vicinities became important sites for entomological study by the nineteenth century due to the presence of the Academy of Natural Sciences (established in 1812) and the American Entomological Society (1859). Entomological writing and illustration also flourished in this center for book production. Over time, entomologists’ interest in insects shifted from the ⇒ Read More

Environmental Movement

With its industrial past and expanses of natural resources, the Greater Philadelphia region teemed with activity during the environmental movement of the late twentieth and early twenty-first centuries.

Eugenics

In 1883 Francis Galton (1822–1911), an English statistician and sociologist, invented a term for his decades-long genealogical investigations into “fit” and “unfit” families: eugenics, the scientific study of being well-born. While Galton tended to focus on the fit, in the United States, enthusiasts for eugenics more often focused on those deemed biologically unfit. Elwyn, Pennsylvania, ⇒ Read More

Ferries

Long before bridges, trestles, and elevated expressways, the people and products of Greater Philadelphia required a network of ferries to traverse the region’s numerous waterways. Once ubiquitous on the area’s rivers, ferries were economic necessities that were phased out over time as industry changed and transportation improved. Until the advent of steam and internal combustion ⇒ Read More

Films (Feature)

Philadelphia’s association with movie-making dates back to the beginning of the film industry, when the city’s Lubin Manufacturing Company created and distributed many of the first generation of silent films. But after the company’s early collapse, the city never again attained a prominent role in the nation’s filmmaking. After Lubin, Philadelphia served as a setting ⇒ Read More

First Purchasers of Pennsylvania

Upon receiving his grant for Pennsylvania in March 1681, William Penn (1644-1718) immediately set about attracting investors and settlers.

The “First Purchasers” who responded to his promotional tracts provided essential economic support for Penn’s “Holy Experiment.” Penn sought to attract ⇒ Read More

Flaxseed and Linen

In the colonial era linen and flaxseed were fundamental to the mercantile life of Philadelphia and the Delaware Valley. Philadelphia’s linen and flaxseed market extended from the farthest point of settlement, Fort Pitt, to the fields of England and Ireland.

Football: Professional

From the 1950s onward, pro football’s Eagles ruled the sports roost in Philadelphia, having built a dedicated fan base that filled the stadium each week and careened emotionally from each gridiron success and failure. Moreover, fierce play on the field was echoed by unbridled passion in the stands. That did not change even as the ⇒ Read More

Forts and Fortifications

Constructed from the seventeenth through the mid-twentieth century, defensive fortifications along the lower Delaware River and bay guarded the region during times of international and sectional upheaval. As important structures with such long histories, forts help to explain the political, economic, and social history of the Greater Philadelphia region. The earliest fortifications in the lower ⇒ Read More

Fox Hunting

Fox hunting, the sport of mounted riders following a pack of hounds that are hunting a fox by scent, became a popular leisure activity of the emerging gentry in the Philadelphia region during the eighteenth and nineteenth centuries. It survives as a twenty-first-century pastime, even though development has reduced the available countryside, and animal-rights activists ⇒ Read More

Freedom Train

On September 17, 1947, a seven-car train arrived in Philadelphia’s Broad Street Station carrying 130 articles of American history, including documents, prints, pictures, and flags, intended to represent this history’s most important legacy: freedom. After its launch in Philadelphia, the Freedom Train went on a 29,000-mile journey to three hundred communities throughout the United States, ⇒ Read More

Fries Rebellion

In 1798, while Philadelphia served as capital of the United States, a new federal tax and the Alien and Sedition Acts sparked resistance in rural Bucks, Montgomery, and Northampton Counties of Pennsylvania. The reputed ringleader John Fries (1750-1818) was twice convicted of treason but received a presidential pardon. Beyond local disruption, the rebellion played a ⇒ Read More

Garbage Barge (Khian Sea)

During the 1980s, as regional landfills closed, it became increasingly difficult for Philadelphia to find places to put its trash and the ash from burning that trash. This dilemma became a global odyssey when the city loaded about 15,000 tons of municipal ash on a ship, the Khian Sea, and sent it off to the ⇒ Read More

Garies (The) and Their Friends

Published in London in 1857, Frank J. Webb’s The Garies and Their Friends is among the earliest novels written by an African American.

Garment Work and Workers

Garment work was once one of Philadelphia’s largest industries. Clothing and textiles (a category including hosiery, a Philadelphia specialty) employed more than 40 percent of the city’s paid workforce by 1880. Starting in the first third of the nineteenth century, the garment industry became a center of labor activism, experiencing periodic strikes and union organizing ⇒ Read More

Gas Stations

The widespread adoption of the passenger automobile during the twentieth century altered the physical landscape of Greater Philadelphia and the United States. By the late 1910s, gas stations began to serve Philadelphia drivers seeking fuel for occupational and recreational travel. Since consumers could not visually determine the quality of gasoline, petroleum companies distinguished themselves from ⇒ Read More

Genealogy

In the Delaware Valley and the United States, the study of genealogy transformed from a pursuit of the elite in the nineteenth century into the most democratic field of historical research. The search by genealogical researchers for materials of importance that assist with pedigree building, family histories, and searches for heirs has resulted in the ⇒ Read More

Great Depression

The Great Depression, which lasted from 1929 to 1941, was characterized in both the Philadelphia region and the nation by a severe contraction in all levels of economic activity, massive unemployment, widespread bank failures, and sharp price deflation. Many people lost their life savings and their homes. Untold thousands went hungry; some starved. It led ⇒ Read More

Grocery Stores and Supermarkets

Local grocery stores, along with churches, elementary schools, and often saloons, have defined and anchored urban and suburban neighborhoods. General grocery stores first appeared in Philadelphia and the surrounding area in the early nineteenth century and increased in number after the Civil War as populations exploded in industrial cities like Camden and Philadelphia and their ⇒ Read More

Helicopters

From barns and airfields throughout the Delaware Valley, during the twentieth century innovative individuals and local companies made greater Philadelphia the nation’s cradle of rotary-wing aviation.

High School Sports

Originating in the nineteenth century, high school sports accompanied the spread of secondary schooling and became a nationwide phenomenon as students initiated team competitions and schools instituted physical education programs. In the Philadelphia region, early scholastic sports gained legitimacy from mentoring provided by the area’s many colleges and from the School District of Philadelphia’s commitment ⇒ Read More

Higher Education: Private (Religious)

With the exception of Greater Boston, the Philadelphia region has more independent colleges and universities than any other metropolitan area of the United States. These numbers stem in large part from the variety of religious communities in the region, all of whom wanted to enjoy the prestige of having an institution of higher learning. Originally, ⇒ Read More

Hinterlands

Since its founding, Philadelphia has acted as a commercial hub for the surrounding region, its hinterlands. Although New Jersey and Delaware had European settlers before Philadelphia’s establishment in 1682, Pennsylvania and its founding city quickly became the focus of economic activity in the region extending both east and west of the Delaware River. With an advantageous ⇒ Read More

Historic Districts

Throughout the Philadelphia area, in communities large and small, concentrations of buildings, landscapes, and natural features that collectively reflect the region’s cultural and historical development have been documented and recognized as historic districts.

Historic Preservation

Through more than three centuries of building and rebuilding settlements, towns, and cities, the region centered on Philadelphia and spanning southeastern Pennsylvania, South Jersey, and northern Delaware became a living museum of American architectural history. The fate of structures ranging from log cabins and colonial mansions to courthouses, warehouses, and the famed Independence Hall often ⇒ Read More

Historical Societies

Over the nineteenth and twentieth centuries, Americans started establishing historical societies to collect and preserve historical materials. In 1815, Philadelphia became the fourth U.S. city to host a historical society, the American Philosophical Society’s Historical and Literary Committee. The city’s religious tolerance and central location made it a natural location for religious and ethnic societies. ⇒ Read More

Hog Island

Hog Island, at the confluence of the Delaware and Schuylkill Rivers, exemplifies many broad trends in the environmental history of the region. Once improved for agriculture, the natural landscape ultimately deteriorated through overexploitation, leading to its conversion for industrial, commercial, and other forms of development. No longer productive in the early twentieth century, the island ⇒ Read More

Horses

Horses played a critical role in Philadelphia’s growth and development as an industrial city, but over time their role as prime movers gradually diminished, and after the mid-twentieth century their role was primarily recreational. Although horses have become associated with the countryside or the American West, American cities had large, concentrated populations of horses well ⇒ Read More

Horticulture

The history of horticulture in Philadelphia and the Delaware Valley has been primarily a story of exploration, beautification, and preservation. Due to the relatively mild climate and fertile soils of the region, Native American groups practiced horticulture long before the arrival of Europeans. Colonists brought gardening traditions from their homelands and ushered in a new ⇒ Read More

Hospitals (Economic Development)

As the twenty-first century began, hospitals and academic medical centers played a central role in the economies of many major U.S. cities, including Philadelphia. As centers not only of patient care but also of scientific research and, often, sources of urban redevelopment, urban medical institutions created jobs in deindustrialized cities and spurred the spatial, social, ⇒ Read More

Hotels and Motels

As one of the busiest and most influential port cities in colonial and later independent America, Philadelphia became an early leader in hotel development and continued to elevate industry standards throughout the nineteenth and twentieth centuries. Hotels presented travelers with a desirable alternative to staying in private residences, and luxury hotels became signifiers of a ⇒ Read More

Hurricanes and Tropical Storms

The Greater Philadelphia area’s position near the Atlantic Ocean has made it vulnerable to hurricanes and tropical storms, especially along the Delaware and New Jersey shores, and to flooding from storm surges along the Delaware River. The majority of storms to hit the region have been tropical storms, because hurricanes have tended to weaken over ⇒ Read More

I-95

Interstate 95—known as the Delaware Expressway in the Philadelphia area—is one of the region’s key transportation conduits. Running alongside the western bank of the Delaware River, it links central Philadelphia with Mercer County in New Jersey and Bucks and Delaware Counties in Pennsylvania. Conceived and built in an era when planners promoted automobile traffic above ⇒ Read More

Immigration (1790-1860)

The revival of immigration to Philadelphia and its surrounding region in the early nineteenth century provided one of the most powerful elements in reshaping the city’s society. After a decline in immigration during the wars of the French Revolution and the Napoleonic era, the growing industrialization of the Philadelphia region began to attract streams of ⇒ Read More

Immigration (1870-1930)

During the national explosion of immigration that took place between 1870 and the 1920s, the Philadelphia region became more diverse and cosmopolitan as it was energized by immigrants who indelibly changed the character of the places where they settled. With its reputation as the “Workshop of the World,” Philadelphia attracted immigrants to jobs in industry, ⇒ Read More

Immigration (1930-Present)

For most of the decades since the United States’ immigration restriction acts of the 1920s, Philadelphia was not a major destination for immigrants, but at the end of the twentieth century the region re-emerged as a significant gateway. Beginning with changes in U.S. law in 1965 and accelerating by the 1990s, immigration added large, diverse ⇒ Read More

Immigration and Migration (Colonial Era)

European settlement of the region on both sides of the Delaware River dates to the early seventeenth century. The population grew rapidly after 1682, when Pennsylvania’s policy of religious tolerance and its reputation as the “best poor man’s country” attracted people from all walks of life. By the time of the American Revolution, Philadelphia was ⇒ Read More

Independence Seaport Museum

The Independence Seaport Museum, originally called the Philadelphia Maritime Museum, addressed the lack of written history of the Port of Philadelphia by collecting, documenting, and exhibiting the region’s nautical legacy. Founded in 1960 by attorney, civic leader, and maritime collector Joseph Welles Henderson (1920-2007), the museum focused on the maritime history of Pennsylvania, New Jersey, ⇒ Read More

Industrial Workers of the World

In the early 1900s thousands in greater Philadelphia belonged to the Industrial Workers of the World (IWW)—a militant, leftist labor union. Local 8, which organized the city’s longshoremen, was the largest and most powerful IWW branch in the Mid-Atlantic and the IWW’s most racially inclusive branch. Indeed, there might not have been a more egalitarian ⇒ Read More

Infectious Diseases and Epidemics

Despite Philadelphia’s prominence, throughout its history, as a center for medical education and care, the region has experienced numerous epidemics of infectious disease. British America’s largest city in the eighteenth century, Philadelphia suffered dreadful outbreaks of smallpox and yellow fever, while the nineteenth century brought an exotic new disease—cholera—that killed hundreds. By the early twentieth ⇒ Read More

Influenza (“Spanish Flu” Pandemic, 1918-19)

As World War I drew to a close in November 1918, the influenza virus that took the lives of an estimated 50 million people worldwide in 1918 and 1919 began its deadly ascent. The United States had faced flu pandemic before, in 1889-90 for example, but the 1918 strain represented an altogether new and aggressive ⇒ Read More

Inner Suburbs

Presenting a varied and complicated patchwork of both thriving and distressed communities, Philadelphia’s inner suburbs developed during different eras to serve different purposes and populations. European influence predated the Revolutionary War with English, Swedish, Dutch, and Welsh settlers establishing tight-knit farming communities in what were then outlying areas of William Penn’s Philadelphia. During the eighteenth ⇒ Read More

Insurance

Insurance is sometimes called an “invisible” element of commerce, but in Philadelphia, it has never been far from view. From the eighteenth century through the twenty-first, Philadelphia’s leadership in the field of insurance has enhanced the city’s preeminence in many types of commercial and communal endeavor. Insurance in Philadelphia, over the years, has meant everything ⇒ Read More

Irish (The) and Ireland

Contacts between the Philadelphia region and Ireland began in the late seventeenth century, shortly after the creation of Penn’s colony.

Tate, ⇒ Read More

Iron Production

Long before western Pennsylvania dominated the American iron and steel industries, southeastern Pennsylvania and southern New Jersey became the epicenter of colonial iron production. In a little over forty years beginning in 1716, Pennsylvania ironmasters erected nearly fifty furnaces and forges for producing iron stock and goods, and by 1840 the region’s national preeminence had ⇒ Read More

Jewelers Row

Jewelers Row in Center City Philadelphia emerged in the 1880s and over time became home to more than two hundred jewelry retailers, wholesalers, and craftsmen. Many of these businesses were owned by the same families for generations. By the twenty-first century, Jewelers Row had become regarded as the oldest diamond district in the United States, ⇒ Read More

King of Prussia, Pennsylvania

Twenty miles northwest of downtown Philadelphia, where the Pennsylvania Turnpike converges with the Schuylkill Expressway, a sleepy rural town clustered around a colonial-era tavern expanded massively in the twentieth century to become the region’s largest employment hub outside of Center City Philadelphia. Its suburban location in fast-growing Montgomery County proved irresistible to real estate developers ⇒ Read More

Korean War

Although active hostilities during the Korean War lasted for little more than three years (1950-53), the conflict had a lasting impact on the Philadelphia area. The war provided a boost for the shipbuilding industry on both sides of the Delaware River, and military bases played a major role in preparing soldiers and supplies for deployment. ⇒ Read More

Lafayette’s Tour

When the Marquis de Lafayette (1757-1834), a French hero of the American Revolution, returned to the United States in 1824-25, Philadelphians joined in a wave of nationwide affection for the nobleman who had volunteered for service in the Continental Army at the age of 19. Lafayette’s return to the region stirred increasing regard for preserving ⇒ Read More

Landfills

Like many other towns and cities across the United States, municipalities in the Philadelphia region adopted the sanitary landfill as a primary refuse-disposal strategy in the mid- to late twentieth century. Intended to replace open dumps, landfills also promised to serve the disposal needs of a rapidly growing suburban population. From the 1950s to the ⇒ Read More

Lazaretto

Situated roughly ten miles south of Philadelphia, in Essington, on the west bank of the Delaware River, the Lazaretto is considered to be the oldest and last surviving quarantine station in the United States. Throughout most of the nineteenth century, the Lazaretto was the first stop for immigrants and merchants on incoming ships whose passengers ⇒ Read More

Lehigh Valley

Over the centuries, strong ties of transport, investment, and culture grew between the Greater Philadelphia region and the Lehigh Valley. The valley was carved by retreating glaciers twenty thousand years ago and maintained by its namesake river running from the Pocono Mountains, through Blue Mountain, south and east into the Delaware River. Only in recent ⇒ Read More

Levittowns (Pennsylvania and New Jersey)

The iconic Levittown communities–the first in Long Island, New York, and the subsequent two in Bucks County, Pennsylvania, and Burlington County, New Jersey–endure as symbols of the unique character of post-World War II U.S. suburban development. A confluence of forces encouraged the particular nature of these large-scale, mass-produced, low-cost suburban tract housing developments, including a ⇒ Read More

Lewis and Clark Expedition

On a November day during the severe winter of 1805, a parcel containing over sixty plants, rocks, and fossils arrived at the American Philosophical Society in Philadelphia. Collected by Meriwether Lewis (1774-1809), these were specimens from the Corps of Discovery Expedition (1803-1806), the western journey of Lewis and William Clark (1770-1838). While the explorers became ⇒ Read More

Lotteries

Lotteries have a long and controversial history in the Philadelphia region.

Lynching

Lynching, the extralegal killing of a victim by individuals or a mob, notably by hanging or burning, was commonplace in the United States at the turn of the twentieth century. Though accounts vary, in the heyday of lynching following the Civil War, at least 3,500 incidents were recorded; more than 80 percent occurred in the ⇒ Read More

Machining and Machinists

Hundreds of machine shops, large and small, built and maintained Philadelphia’s position as the “Workshop of the World” through the nineteenth and twentieth centuries. In the city and beyond, especially in Conshohocken, Pottstown, Phoenixville, Chester, and Camden, machining made the Delaware Valley a hub of foundries, craft shops, mills, workshops, and manufactories. During the latter ⇒ Read More

Mansions

Since the earliest European settlement in the seventeenth century, but especially from the eighteenth to the twentieth centuries, large houses constructed by elites in the Philadelphia region provided agreeable places to live that demonstrated social status. As architectural fashion and geographic distribution changed, mansions served as conspicuous symbols for elite Philadelphians and were a salient ⇒ Read More

Manufacturing Suburbs

Although early industrialization in the eighteenth century took root mainly in urban centers, a substantial share of the Philadelphia region’s early manufacturing sprang up in small towns outside the young city. The explanation for that pattern lay in the region’s great rivers, the Delaware and Schuylkill. As early as the eighteenth century, enterprising settlers saw ⇒ Read More

Maps and Mapmaking

As the country’s largest city, and for a time capital of the new nation, Philadelphia was well situated to chart the young republic’s changing geography. Using its capacity to attract all the manufacturing elements necessary for successful publishing—printers binders, colorists, engravers and others—Philadelphia became the home of the nation’s first full-time geographical publisher and soon ⇒ Read More

March of the Mill Children

The March of the Mill Children, the three-week trek from Philadelphia to New York by striking child and adult textile workers launched on July 7, 1903, by Mary Harris “Mother” Jones (1837-1930), trained public attention on the scourge of child labor and energized efforts to end it by law. Jones, the storied Irish-born labor organizer, ⇒ Read More

Martin Luther King Jr. Day

Philadelphia has had a greater influence on Martin Luther King Jr. holiday traditions than any city other than King’s birthplace, Atlanta. Observed on the third Monday in January since 1986, the federal holiday commemorates King (1929-68) and his civil rights activism. Ceremonies at the Liberty Bell and a focus on community service are among Philadelphia’s ⇒ Read More

Mason-Dixon Line

The Mason-Dixon Line, which settled a border dispute dating back to the founding of Philadelphia, is the southern boundary of Pennsylvania.

By the early years of the twenty-first century, Mennonites in ⇒ Read More

Meteorology (Study of the Atmosphere)

Philadelphians have pursued significant scholarly and popular interests in meteorology, the scientific study of the atmosphere, since the eighteenth century. Pioneering individuals, including Benjamin Franklin (1706–90) and Reuben Haines (1786–1831), tracked meteorological data, and scientific societies made the practice increasingly systematic by the late nineteenth century. Short-term weather forecasting became possible as technological innovations such ⇒ Read More

Mexican-American War

Despite taking place in the American Southwest and Central America, the Mexican-American War (1845-48) had significant ties to the Philadelphia area. As one of the most populous urban centers in the country, the Delaware Valley became a hotbed of activity for one of the most controversial wars in American history. War between the United States ⇒ Read More

Mexicans and Mexico

Greater Philadelphia’s economic ties to Mexico date to the era of European colonization. However, substantial Mexican immigration to the region started only in the 1970s, in Chester County’s mushroom growing towns, and in the 1990s in Philadelphia. Still, Mexicans became the region’s second-largest immigrant group in the early twenty-first century and were the largest immigrant ⇒ Read More

Mighty Macs

The Immaculata College women’s basketball teams of the early 1970s, known as the Mighty Macs, won the first three national tournaments of the Association of Intercollegiate Athletics for Women (AIAW) in 1972, 1973, and 1974.

Militia

As the social and political center of colonial Pennsylvania, Philadelphia and the surrounding region served as a microcosm for the complex and often convoluted history of the colonial and early national militia. The role of Philadelphia militia also illustrates the nature of militia units during the American Revolutionary War. The first militia in the region ⇒ Read More

Model Cities

The Model Cities program was the last major urban aid initiative of the Great Society domestic agenda of President Lyndon Johnson (1908-73). The legislation called for the coordination of federal services to redevelop the nation’s poorest and least-served urban communities. In 1967, North Philadelphia was designated for renewal under this program. Rather than serving to ⇒ Read More

Monopoly

Although an unemployed Philadelphia salesman, Charles Darrow (1889-1967), was long credited as the creator of the world’s most popular board game, the origins of Monopoly stretch several decades before Parker Brothers purchased the rights from Darrow in 1935 and beyond the iconic streets of Atlantic City featured in the game. The proper history of Monopoly ⇒ Read More

Montgomery County, Pennsylvania

The early Europeans who settled in what would become Montgomery County in the eighteenth century tended prosperous farms, forges, and mills.

Election Day in 1871, just one year after the Fifteenth Amendment to the U.S. ⇒ Read More

National Guard

The roots of the National Guard can be traced to Philadelphia and congressional action during the city’s decade as the nation’s capital.

National Parks

National parks figure prominently in Greater Philadelphia’s cultural, economic, and natural landscapes. Morristown (1933), Independence (1948), Valley Forge (1976), and First State (2015) National Historical Parks all preserve and provide access to sites associated with the American Revolution and early American history. Together they welcome nearly six million visitors each year and create more than ⇒ Read More

Native American-Pennsylvania Relations 1681-1753

Indian-brokered alliances more than Quaker pacifism anchored the “long peace” in the decades that followed Pennsylvania’s founding in 1681.

Native American-Pennsylvania Relations, 1754-89

Relations between Pennsylvania’s Native American and European peoples underwent cataclysmic change during the second half of the eighteenth century. Despite the reputation for peaceful intercultural relations that Pennsylvania had enjoyed since its founding in 1681, a series of wars engulfed its frontiers after 1754, leading to the dispossession and exile of the colony’s native peoples. ⇒ Read More

Native and Colonial Go-Betweens

During the colonial period, the diversity of the region that became southeastern Pennsylvania, southern New Jersey, and northern Delaware made trade and diplomacy difficult. The many cultural, especially linguistic, barriers between various Native American and European groups required go-betweens, or intermediaries. The intermediaries who were called upon to interpret across cultures and help maintain the ⇒ Read More

New Sweden

Founded in 1638, the colony of New Sweden survived less than twenty years and at its peak numbered only about four hundred people, most of whom lived along the western bank of the Delaware River between what became Philadelphia and New Castle, Delaware.

Nuclear Power

Mirroring a nation-wide wave of commercial interest in nuclear power plants in the 1950s and 1960s, the Philadelphia Electric Company (PECO) and other energy companies in Greater Philadelphia jumped at the opportunity to develop relatively inexpensive electricity for the region. Nuclear power plants began servicing the region’s electrical grid in 1967. However, as was the ⇒ Read More

Nursing

The history of nursing in the Philadelphia area is one of long and storied traditions. Men and women have often nursed their sick families and friends at home, which for millennia represented the best, safest, and most comforting site for treatment and care.

Omnibuses

One of the earliest forms of public transportation in Philadelphia (and its early suburbs prior to the 1854 consolidation of the city with the county) was the horse-drawn omnibus introduced in 1831. The omnibus, together with the railroad, created the first urban commuters and it effectively became the model for all future street-based public transportation ⇒ Read More

Opera and Opera Houses

Opera has played an important role in Philadelphia arts and entertainment since the mid-eighteenth century.

Orchard Window (The)

Painted in 1918 by Philadelphia artist Daniel Garber (1880-1958), The Orchard Window depicts the interior of Garber’s studio in Bucks County, Pennsylvania, and features his 12-year-old daughter Tanis sitting in a sun-dappled window seat, reading a book. This large oil painting on canvas has been highly regarded as a prime example of Pennsylvania Impressionism, a ⇒ Read More

Ornithology (Study of Birds)

While Philadelphians maintained scientific interest in birds between the eighteenth and twenty-first centuries, the region became an important scholarly center for ornithology by the early nineteenth century. Primarily known for taxonomy (the science of classifying organisms), ornithological study transformed in the 1860s after the scientific community discovered a conclusive evolutionary link between birds and dinosaurs. ⇒ Read More

Pacific World (Connections and Impact)

Historians have often situated Philadelphia in three geographic contexts: on the western edge of the “Atlantic World” during the colonial era, as an eastern metropole for hinterlands and the receding frontier to the west, and in the mid-Atlantic region between the North and South of the United States. These geographic frames all make sense, given ⇒ Read More

Paints and Varnishes

From colonial times to the nationwide deindustrialization trend starting in the 1950s, Philadelphia played a leading role in providing American and overseas markets with quality paints and varnishes. “Oil and Colours” merchants of the colonial period turned, during the early nineteenth century, into family-owned-and-managed manufacturing companies, as they opened paint and varnish factories in Center ⇒ Read More

Paper and Papermaking

Home to the first paper mill in the British American colonies, Philadelphia was the nation’s primary papermaking center through the early nineteenth century.

Pennsylvania Impressionism

Pennsylvania Impressionist painting flourished in eastern Pennsylvania in the first half of the twentieth century.

It served as a major commercial hub of the nascent nation and became its financial ⇒ Read More

Philadelphia County, Pennsylvania

Dating to 1682, Philadelphia County’s founding coincided with the origin of the city. Although the county faded from view after its consolidation with the city in 1854, it remained important for understanding Philadelphia’s urban development, local government, and long battles for political reform.

When American patriots declared independence from Great Britain in 1776, the single largest boon to their cause was the nation’s ability to feed itself—as well as much of the Atlantic world. Beginning in the mid-1700s, crop failures across Europe and an expanding slave population in the West Indies created a huge demand for food from ⇒ Read More

Plays and Playwrights

Upon first glance, it may seem odd that in Philadelphia, the intellectual heartland of the American Enlightenment, the first drama did not play until April 1754, over seventy years after the city’s founding. That play, The Fair Penitent by Nicholas Rowe (1674-1718), was licensed for twenty-four performances, with the warning that the license would be ⇒ Read More

Point Breeze (Bonaparte Estate)

Joseph Bonaparte’s Point Breeze estate was one of the finest country houses in the Delaware Valley. Similar grand houses once graced the Delaware Valley, especially upriver from Philadelphia and along the Schuylkill. The first was likely Pennsbury Manor, the American home of William Penn (1644-1718). Many of these country houses still stand, including the Woodlands, ⇒ Read More

Police Athletic League

Since 1914, police officers in urban areas have seen the need for better relations between the police and local youth as a means of reducing crime and promoting wholesome play under proper supervision. In that spirit, the first Police Athletic League (PAL) in the greater Philadelphia area formed in North Philadelphia in 1947 “to build ⇒ Read More

Pontiac’s War and the Paxton Boys

Pontiac’s War (1763-66), a conflict between Native Americans and the British Empire, began in the Great Lakes and Ohio Valley regions but had important ramifications for Philadelphians as panic in the Pennsylvania backcountry sent refugees to the city. The arrival of the “Paxton Boys,” who were determined to seek revenge against Indians, sparked a political ⇒ Read More

Prehistoric Native Americans and Archaeology

For thousands of years before European settlement, Native Americans inhabited North America and left behind evidence of their lives in the form of artifacts, which archaeologists have studied and interpreted. The archaeological record for Philadelphia and the surrounding area reveals the complex relationship between prehistoric peoples and the region’s changing environment. Archaeologists also have learned ⇒ Read More

Presidents of the United States (Presence in Region)

Presidents of the United States, seeing Philadelphia as the city most connected to American independence, often have turned to the city and region to campaign, advance their agendas, and commemorate the past.

Printing and Publishing

From the late seventeenth century to the mid-twentieth century, Philadelphia’s printing and publishing industry was a central component of the city’s evolution from “Green Country Town” to “Cradle of Liberty” to “Workshop of the World.” Growing their operations from small do-it-all shops into large fully mechanized publishing houses, Philadelphia’s printers and publishers capitalized on the ⇒ Read More

Printmaking

Beginning in the mid-nineteenth century, Philadelphia became a leading center of printmaking in the United States.

Duval (1804/5-86) transformed Philadelphia’s lithographic trade into a booming industry. Duval’s commitment to improving printmaking methods and achieving ⇒ Read More

Prisons and Jails

In the late 1700s, on the heels of the American Revolution, Philadelphia emerged as a national and international leader in prison reform and the transformation of criminal justice practices. More than any other community in early America, Philadelphia invested heavily in the intellectual and physical reconstruction of penal philosophies, and the region’s jails and prisons ⇒ Read More

Private (Independent) Schools

The private or independent schools in the Greater Philadelphia area came about mainly to satisfy a need felt by wealthy, white families to educate their children in a cultural and intellectual environment that would prepare them for the responsibilities befitting their gender, race, and class status. Most have existed for at least a century. Although ⇒ Read More

Proclamation Line of 1763

The Royal Proclamation of 1763 created an imaginary line along the Appalachian Mountains that prohibited European settlement beyond the crest of the mountains, approximately two hundred miles west of Philadelphia. It thus established the region from the eastern seaboard to the mountains as the extent of British North America. In Pennsylvania the proclamation heightened racial, ⇒ Read More

Prohibition

Despite the national prohibition of alcohol from 1920 to 1933, Philadelphia earned a reputation rivaling Chicago, Detroit, and New York City as a liquor-saturated municipality. The Literary Digest described Pennsylvania as a “bootlegger’s Elysium,” with every city as “wet as the Atlantic Ocean.” The Quaker City in particular was singled out, by newspapers from New ⇒ Read More

Public Education: High Schools

From one of America’s earliest public secondary schools to the large, neighborhood high schools of the early twentieth century and sprawling suburban campuses after World War II, through later experiments aimed at restructuring and reforming urban high schools, Greater Philadelphia has been notable in the development of secondary education in the United States. Central High ⇒ Read More

Public Education: Suburbs

In the second half of the twentieth century, many parents moved their families out of Philadelphia, Camden, or Wilmington so that their children could enroll in suburban public schools because they perceived them to be better than their urban counterparts. Before then, many believed that the best public schools were urban and that rural schools ⇒ Read More

Public Housing

As the dominant response to the housing needs of low-income residents since the 1930s, public housing in the Philadelphia region provided shelter for thousands. Over the years, however, as needs as well as programs changed, the city and the region struggled to provide safe, decent, and sanitary living quarters when the private market failed to ⇒ Read More

Public Markets

Public markets in Philadelphia belong to an ancient tradition of urban food provisioning in which the governing authority designated specific places for the exchange of life’s necessities. A formal and organized system of exchange was intended to attract local and regional producers to the city in order to ensure citizens an adequate supply of healthful ⇒ Read More

Public Media

Philadelphia participated early and actively in the founding and development of public broadcasting, which expanded across the twentieth century to encompass radio, television, and digital platforms. Public media organizations have given voice to local concerns, provided forums for diverse opinions, and offered programming not found in commercial broadcasting. Precedents for public broadcasting originated in the ⇒ Read More

Public Transportation

For more than three centuries public transportation has helped both to shape and define the Greater Philadelphia region. Befitting one of the world’s largest cities, Philadelphia and its hinterland have been served by a bewildering array of transportation options, and these vehicles and routes have helped to define the extent of the region. Public transportation ⇒ Read More

Puerto Rican Migration

Puerto Ricans migrated to the Philadelphia area in search of better economic opportunities. A small stream of migration prior to the twentieth century grew during the two world wars, with many more migrants arriving from the 1950s onward. Many families settled permanently in the region, where their lives intertwined with black and white residents and ⇒ Read More

Puerto Rico and Puerto Ricans

The centuries-long relationship between the Philadelphia region and Puerto Rico unfolded in four interrelated areas: economic links, political channels, personal networks, and cultural exchange. Several dynamics shaped those connections over time. Colonialism, first under Spain and later the United States, set the broad context for trade relations and government policies. Individual reactions to those policies ⇒ Read More

Radio (Commercial)

From radio’s inception to contemporary times, Philadelphia-area innovators, performers, and manufacturers contributed to shaping the industry. Like its technological forerunner, the telegraph, radio made possible the direct, real-time transmission of information. The immediacy and intimacy of radio waves arriving directly into listeners’ homes made radio revolutionary. The medium quickly became not only a technology for ⇒ Read More

Radio (High School and College)

From radio’s earliest days, college and high school students in the Greater Philadelphia area have tested its boundaries. Student radio has been democratizing and distinct. Unrestrained by advertising sponsors, though sometimes constrained by school administrators’ concerns over content and control over budgets, students have freely experimented with format, content, and technology, and each class of ⇒ Read More

Radio DJs

Disc jockeys—“DJs” who play music on the radio—have had a key role in shaping Philadelphia musical tastes since the 1950s. They reflected national and local musical trends, exposed audiences to new music, and in some cases produced records and managed artists. Many Philadelphia DJs became celebrities, actively engaged and influential in the local music scene. ⇒ Read More

Railroad Stations

Railroad stations in Greater Philadelphia evolved with the railway industry into a wide variety of forms and functions. For most passengers and casual observers, railroad stations are buildings, but for the railways, these locations are also key operating points for loading and unloading passengers and freight. The vast majority of railroad stations in the Philadelphia ⇒ Read More

Railroad Suburbs

As railroads reached outlying villages and the countryside around Philadelphia during the nineteenth century, railroad companies and other enterprising real estate developers created fashionable residential enclaves, new suburban towns, and vast semirural estates. These developments enabled prosperous Philadelphians to live apart from the city while still enjoying its amenities and maintaining their positions in the ⇒ Read More

Railroads

The history of the railroad industry in the United States and the growth of the Greater Philadelphia region are inextricably linked. Philadelphia money and engineering built the national network and, from the middle of the nineteenth century to the middle of the twentieth, railroads helped make and maintain Philadelphia as a “Workshop of the World,” ⇒ Read More

Recording Industry

The birthplace of the American “record” industry, the Philadelphia region for more than a century has been home to a thriving industry of recording studios and record companies. In Camden, New Jersey, the Victor Company in the early 1900s was the nation’s largest manufacturer of musical recordings. Since then, Philadelphia’s unique concentration of diversified industries, ⇒ Read More

Red Arrow Lines

The Red Arrow Lines of the Philadelphia Suburban Transportation Company (1936-70) became a national model and local brand of marketable mass transit in the 1950s, when few private companies still built, managed, owned, and operated suburban public transportation services, let alone profited from them. At a time when motor-vehicle commuting forced most transit proprietors into ⇒ Read More

Roman Catholic Education
(Elementary and Secondary)

Parochial schools in the Philadelphia region share a common Catholic mission and similar patterns of growth and development. For more than three centuries they have responded to the changing characteristics of the region’s Catholic population. Several of these developments, such as schools for specific ethnic groups, occurred in Philadelphia, Camden, N.J., and Wilmington, Del., within ⇒ Read More

Roman Catholic Parishes

Parishes stand at the center of Roman Catholic religious life. Since the arrival of Catholicism in the Philadelphia region in the early eighteenth century, parishes have shaped Catholics’ sense of communal identity by functioning as both the administrative unit of a diocese and the primary site of Catholic worship. Developing into expansive complexes that often ⇒ Read More

Roosevelt Boulevard

Snaking its way through parts of North and Northeast Philadelphia, the Roosevelt Boulevard, formally known as the Theodore Roosevelt Memorial Boulevard, has become one of the most heavily traveled thoroughfares in the Philadelphia metropolitan region. Initially conceived amid political maelstroms during the “corrupt and contented” phase of Progressive Era Philadelphia, “the Boulevard,” as it became ⇒ Read More

Salem County, New Jersey

Before Philadelphia’s founding, Salem, New Jersey, was the first English Quaker colony along the Delaware River. Established in 1675, the city of Salem had early prominence and served as a port of entry, but was soon overshadowed by Philadelphia. Although eighteenth-century settlement in Salem County consisted primarily of farmers and craftsmen, the proximity of the ⇒ Read More

Saws and Saw Making

Philadelphia ranked as one of the nation’s foremost saw manufacturing centers for much of the nineteenth and twentieth centuries. Large-scale saw making began locally in the early nineteenth century, and by midcentury a number of major saw manufacturers operated in the city, including the world’s largest, Henry Disston’s Keystone Saw Works. Disston created a unique ⇒ Read More

Schuylkill Expressway

Fully opened for traffic November 25, 1958, Philadelphia’s Schuylkill Expressway was gridlocked from the first day of its operation. Envisioned by city planners as a panacea for economy-suffocating urban traffic congestion, but built on flawed engineering assumptions about traffic flows, the expressway ignored any concern for postwar social and regional realities. Rather than being acclaimed, ⇒ Read More

Schuylkill Navigation Company

While eighteenth-century Philadelphians looked almost exclusively to the east and the Delaware River to connect them to the wider world, by the turn of the nineteenth century they looked increasingly to the Schuylkill River and the west. After several failed attempts to fund improvements that would make the rapid-filled Schuylkill River navigable in the 1780s ⇒ Read More

Scots Irish (Scotch Irish)

Pennsylvania’s Scots Irish, a hybrid people of Scots and Irish ancestry, were the most numerically predominant group within an Irish diaspora migration that brought between 250,000 and 500,000 Irish immigrants (most of them Protestants from Ulster and predominately Presbyterians) to America between 1700 and 1820. Philadelphia was one of their principal destinations. As the prototypical ⇒ Read More

Scrapple

Scrapple, which came to the Philadelphia region from Germany, is a loaf of cooked pig parts thickened with cornmeal or buckwheat usually spiced with sage and pepper. Once cooled, the loaf is sliced, fried, and served as a breakfast side dish, often with syrup. Not just a culinary transplant, scrapple exists because of the interplay ⇒ Read More

SEPTA

The Southeastern Pennsylvania Transportation Authority (better known by its acronym SEPTA) is a state authority charged with funding and operating public transportation in the city of Philadelphia and Pennsylvania counties of Bucks, Chester, Delaware, and Montgomery. Created in 1963, SEPTA often struggled with management issues, employee morale, strikes, aging equipment, inadequate funding, and poor public ⇒ Read More

Seven Years’ War

Philadelphia and the surrounding area played a significant role in the Seven Years’ War (1756-63), also known as the French and Indian War and the Great War for Empire. Beginning in North America and spreading to Europe, India, and the West Indies, the war was a struggle for colonial dominance between France and Great Britain ⇒ Read More

Shipbuilding and Shipyards

Perhaps no business, industry, or institution illuminates the history of the Greater Philadelphia region from the seventeenth century to the present day more clearly than shipbuilding and shipyards. This may seem surprising since Philadelphia and nearby Delaware riverfront ports lie one hundred miles from the Atlantic Ocean up an often treacherous Delaware Bay and river ⇒ Read More

Shoemakers and Shoemaking

One of Philadelphia’s oldest occupations, shoemaking grew in the eighteenth and nineteenth centuries to become one of the city’s leading industries. During that period shoemakers in Philadelphia also became some of the leading figures in the city’s, and the nation’s, burgeoning labor movement. The methods and institutions that these leaders used throughout the nineteenth century ⇒ Read More

Shopping Centers

Shopping centers, which bound retailers together into one physically convenient and accessible commercial venue for suburban consumers, profoundly altered Greater Philadelphia, redefining the region’s socioeconomic dimensions and destabilizing the city’s old, commercial core, the Central Business District. Commercial retailing also underwent significant changes, as the location, planning, and physical proportions of shopping facilities dramatically transformed ⇒ Read More

Shrines

People of faith have long revered significant religious sites, making pilgrimages for special devotion to locations that often developed into formal shrines–places regarded as holy because of their associations with sacred persons, relics, or events. Beginning in the mid-nineteenth century, Roman Catholic churches and other faiths in the Philadelphia area established a number of shrines, ⇒ Read More

Silk and Silk Makers

Philadelphia’s silk industry began in earnest in the early nineteenth century. There had been efforts since the early eighteenth century to cultivate the silk worm and establish silk-making operations in the region, but they had proven unsustainable or were carried out on a small scale. Philadelphia’s first successful silk manufacturer began operating in 1815, and ⇒ Read More

Silver Linings Playbook

The 2012 film Silver Linings Playbook, directed by David O. Russell (b. 1958) and based on the novel by Collingswood, New Jersey, native Matthew Quick (b. 1973), experienced overnight success when it premiered at the Toronto International Film Festival and earned the highly sought-after Audience Award. Filmed in and around Philadelphia, the movie showcases the ⇒ Read More

Smith’s and Windmill Islands

Once a prominent feature of the Delaware River between Philadelphia and Camden, Smith’s and Windmill Islands were shifting signifiers of the recreational, commercial, and financial development of the region. Originally one island, then segmented by a canal in 1838, the islands attracted early but unsuccessful proposals for bridges between Camden and Philadelphia. Although they served ⇒ Read More

Smoking and Smoking Regulations

The origins of smoking tobacco in the Philadelphia region can be traced to the era before European colonization and evolved from pipes and cigars to the commercialization of cigarettes beginning in the late nineteenth century. Philadelphia-area farmers grew tobacco, local manufacturers produced cigars and cigarettes, and the N.W. Ayer advertising agency helped Camel cigarettes become ⇒ Read More

Soccer

Soccer has been played in the Philadelphia area since the late nineteenth century. The rules of Association football, known in the United States as soccer, were formulated in England in 1863. Various forms of football were played in Philadelphia before that time and after, but the first game of soccer in the city “under proper ⇒ Read More

South Asians

South Asian migration to Greater Philadelphia arrived in small numbers through the 1800s from the group of seven countries including India, Pakistan, Bangladesh, Nepal, Sri Lanka, the Maldives, and Myanmar. This large region shared a history of British colonization until as late as 1965, and different migration patterns and political histories made community life unique ⇒ Read More

Spanish-American War

Although often regarded as a minor conflict, the Spanish-American War (1898) made a major impact on Greater Philadelphia. As a populous urban center, Philadelphia and its immediate environs contributed a substantial number of troops to the United States’ volunteer army but also provided an outlet for those dissenters who decried warfare. In addition, the war ⇒ Read More

Sprawl

Despite Philadelphia’s twenty-first century resurgence as the urban center of a vital multistate region, the city’s revival did not stem the tide of outward expansion in a largely uncontrolled pattern known popularly as “sprawl.” The steepest population growth in the region continued to occur in the newer suburbs and rural locales, in a low-density and ⇒ Read More

Street Vendors

From the colonial period to the present, street vendors have been integral yet contentious features of Greater Philadelphia’s economic landscape. Providing massive numbers of customers with food, clothing, and other goods while allowing many working people an occupational foothold in the region, vending also sparked controversies regarding taxes, regulation, public health, and uses of space. ⇒ Read More

Streetcar Suburbs

Beginning in the middle of the nineteenth century, Philadelphia’s growing streetcar network facilitated the movement of upper and middle class Philadelphians to residential districts outside of the urban core. New streetcar-centric suburban developments combined the allure of pastoral living with fast access to work and commerce in central Philadelphia. In this way, streetcar suburbs represented ⇒ Read More

Streetcars

For more than 150 years streetcars have served the Philadelphia area and helped Center City Philadelphia retain its commercial, retail, and entertainment supremacy in an ever-expanding region. Although the motive power switched from horses to electricity (with short detours into steam and cable), most change has been evolutionary rather than revolutionary. Perhaps the greatest transformation ⇒ Read More

Surveying (Colonial)

Land was the most valuable commodity in the Delaware Valley during the colonial period, and it had to be surveyed before it could be granted or transferred. In Pennsylvania, William Penn (1644–1718) relied upon surveyors to measure and map his new lands. Colonial surveyors established tract, manor, township, and county boundaries, laid out city streets ⇒ Read More

Tastykake

“Nobody bakes a cake as tasty as a Tastykake” has been a brand tag line known by virtually every Philadelphian for a century. Indeed, few things are as iconically associated with the city and region as Tastykakes. The company was founded in 1914 by Philip J. Baur and Herbert T. Morris, in the Germantown neighborhood ⇒ Read More

Television

SThe Philadelphia region had a key role in the ascent of television in American popular culture. From the manufacturing of television sets to the production of innovative programming, researchers, technicians, and creative talents in the region produced many of the “firsts” that propelled television to success as a new mass medium in the twentieth century. ⇒ Read More

Television Shows (About Philadelphia)

The Philadelphia region has provided a backdrop for numerous television programs, including shows by creators from the region. Although the programs often were shot in other places, like New York or Los Angeles, the Philadelphia setting provided important references and details. In some cases, stories called for posh suburbs, such as those on the Main ⇒ Read More

Thrift

Philadelphia became a national center for the thrift movement of the late nineteenth and early twentieth centuries as a high concentration of progressive individuals and institutions promoted values of frugality, industry, and stewardship as a means for poor and working-class people to improve their circumstances. Espoused by white middle-class society, the thrift movement declined when ⇒ Read More

Tobacco

Growing, trading in, and manufacturing tobacco were important components of the economy and society of the Delaware Valley for centuries. Early residents raised tobacco for personal use and as a trade commodity, but in most of the region it fell out of favor by the late eighteenth century. The exception was Southeast Pennsylvania, where tobacco ⇒ Read More

Tomato Pie

Served by Italian bakeries in South Philadelphia since the early twentieth century, the tomato pie became known by many names: church pie, square pizza, red pizza, granny pizza, and red pie. Although made in a rectangular or square shape similar to Sicilian-style pizza, tomato pie within the city and surrounding region remained distinct from contemporary ⇒ Read More

Tourism

Philadelphia has been a tourist destination since leisure travel emerged as a common pastime for the middle and upper classes in the nineteenth century. By the twenty-first century, the region’s economy depended heavily on tourism to Philadelphia and nearby destinations such as the Brandywine Valley, Valley Forge, and the Jersey and Delaware shores. Historic sites ⇒ Read More

Trails (Indian)

In the Philadelphia region prior to European settlement and during the colonial period, the Lenapes and other Indians used their knowledge of the landscape to engineer the most efficient routes through forests, mountains, and often shallow, treacherous waterways. Their complex system of overland paths crisscrossed the region to reach east to the shell fisheries on ⇒ Read More

Trees

Trees have been culturally, environmentally, and symbolically significant to the Philadelphia region since the city’s founding. They were believed to improve public health, they beautified and refined city streets, parks, and other green spaces, and several were revered as living memorials to past historical events. Trees also faced their fair share of destruction during the ⇒ Read More

Trenton and Princeton Campaign (Washington’s Crossing)

One of the most significant events in the Revolutionary War was the Continental Army’s December 25, 1776, crossing of the Delaware River, led by General George Washington (1732-99), which preceded three crucial American victories—two at Trenton and one at Princeton, New Jersey—that reignited the virtually extinguished Patriot cause. Immortalized in the famous 1851 painting by ⇒ Read More

Typhoid Fever and Filtered Water

Philadelphia in the late nineteenth century stood shamefully high among large American cities in rates of death from typhoid fever (also known as enteric fever). Caused by a type of Salmonella bacterium, the disease had become common in Philadelphia and other cities with crowded populations, inadequate disposal of human waste, and lack of water treatment. ⇒ Read More

U.S. Congress (1790-1800)

During the 1790s, while Philadelphia served as the nation’s temporary capital, the U.S. Congress met problems and threats to the nation that tested the endurance of the Constitution and the republic it framed. Domestic issues of finance, taxation, sectionalism, Indian affairs, and slavery divided the delegates into bitter political camps, and international relations fomented disagreements ⇒ Read More

Underground Railroad

With a deep abolitionist history and large and vibrant free black population, Philadelphia and the surrounding region played a prominent role in the famed Underground Railroad. The loosely connected organization of white and black people helped hide and guide enslaved people as they sought freedom in the North and Canada. According to one of the ⇒ Read More

United States Colored Troops

During the American Civil War (1861-65), Philadelphians raised eleven regiments of the United States Colored Troops (USCT). This division of the United States Army, consisting of black soldiers led by white officers, provided much-needed manpower for federal forces in the final two years of the war. When the Civil War began, many African Americans across ⇒ Read More

Valley Forge

In 1777 the Continental Army, unable to prevent the British forces from taking Philadelphia, retreated to Valley Forge for the winter of 1777-78. Selected for its strategic location between Philadelphia and York, along the Schuylkill River, Valley Forge had natural defensive positions, access to water, enough land to support the army, and was far enough ⇒ Read More

Veterans and Veterans’ Organizations

Military veterans began organizing in the Philadelphia area during the waning days of the Revolutionary War. As the Continental Army disbanded, its veterans often met at City Tavern and the first general meeting of America’s first veterans’ organization, the General Society of the Cincinnati, occurred there on May 4, 1784. Just as regularly, however, veterans ⇒ Read More

Vietnam War

The Vietnam War, like the Great War, World War II, and Korean War before it, had a significant impact on the Philadelphia region. During the height of open American involvement in the war from 1965 to 1968, thousands from the area were drafted or volunteered for the armed forces, and hundreds lost their lives. Other ⇒ Read More

Vigilance Committees

As Pennsylvania and other northern states became havens for enslaved people who sought to escape bondage, free blacks and sympathetic whites organized Vigilance Associations, which operated Vigilance Committees (sometimes called Vigilant Committees) to protect fugitives and potential kidnap victims. After black abolitionist David Ruggles (1810-49) formed the first such organization in New York City in ⇒ Read More

Vine Street Expressway

The Vine Street Expressway (Interstate 676), a 1.75-mile depressed limited-access highway traveling east-west across the northern edge of Philadelphia’s central business district, resulted from more than sixty years of effort to connect I-95 and I-76 and move traffic more easily between and through the city to surrounding counties in Pennsylvania and New Jersey. Its route ⇒ Read More

Walking Purchase

With the Walking Purchase of 1737, Pennsylvania officials defrauded the Delaware Indians out of a vast amount of land, perhaps over one million acres, in the Delaware and Lehigh Valleys. John Penn (1700-46) and Thomas Penn (1702-75), the sons of William Penn (1644-1718), with James Logan (1674-1751), the provincial secretary of Pennsylvania, devised the land ⇒ Read More

West Chester, Pennsylvania

Boosted by its strategic location some twenty-five miles from Philadelphia, West Chester, Pennsylvania, grew and prospered for most of its history as the county seat of Chester County. Pressured by mid-twentieth-century suburbanization, the borough lost its commercial and residential dominance and even its role as county seat somewhat diminished as the growth of the surrounding ⇒ Read More

Woman Suffrage

While the Philadelphia region often led the way on progressive reforms, by the twentieth century, woman suffrage was not among them. The region boasted a number of early woman suffrage advocates, and women in New Jersey had the right to vote during the early years of the republic, but by the late nineteenth century, Pennsylvania ⇒ Read More

Women’s Clubs

The woman’s club movement began throughout the United States in the late nineteenth century. Although initially focused on self-improvement, women’s clubs in the Philadelphia region as in the nation quickly extended their goals to include community activism. Drawing upon contemporary assumptions about the inherent differences between men and women, leaders of the club movement argued ⇒ Read More

Woodbury, New Jersey

Located on the Woodbury Creek in the northwestern part of Gloucester County, Woodbury formed as a result of the first Quaker family to settle the area, in 1683. Initially a lightly populated farming community, the village eventually became the seat of Gloucester County and over time emerged as an important center for transportation, manufacturing, and ⇒ Read More

Works Progress Administration (WPA)

In response to the rising tide of unemployment nationally, and after the short-lived Civil Works Administration (CWA) failed to stem that tide, Congress in May 1935 created the Works Progress Administration (WPA), one of the “alphabet soup” of economic recovery programs enacted as part of the New Deal of President Franklin D. Roosevelt (1882-1945). Later ⇒ Read More

World War I

Although the United States’ military involvement in the First World War lasted just over a year, the conflict in Europe had a lasting impact on the Philadelphia region. The war created new opportunities for the industrial base of Philadelphia, Chester, and Camden, and as men and women enlisted for military service, the region developed a ⇒ Read More

World War II

World War II, which created change for industries, populations, and politics in many urban areas in the United States, had a transforming effect on the Philadelphia region. Already industrialized, the region gained new impetus from government orders for supplies, armaments, transportation, and more. Philadelphia-area industries expanded, making the region a major “arsenal for democracy” during ⇒ Read More

Yellow Fever

For more than a century beginning in the late seventeenth century, sudden outbreaks of yellow fever sowed death and panic throughout Philadelphia and its environs. With medical science seemingly powerless against it, yellow fever was a terrifying and mysterious threat that rivaled any disease of the era in its capacity to take lives and disrupt ⇒ Read More

Zoning (Philadelphia)

From its inception, zoning became a fraught subject. By empowering neighborhood groups and local politicians with power over land use in their communities, zoning brought such groups in Philadelphia and elsewhere into contest with developers, industrial concerns, and sometimes with other people who wanted to move into their neighborhoods. The policy generated results both noble, ⇒ Read More
