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. Based in Philadelphia, then the national capital, the bank drew many principal investors from the region and ⇒ Read More

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

Ceramics

Once on par with other industries that gave Greater Philadelphia its reputation as the “Workshop of the World,” ceramic production played a key role in the region’s economic and artistic significance. Innovative makers and entrepreneurs produced a spectrum of utilitarian pottery and refined luxury goods, making visible the shifting patterns of consumption, taste, and technology ⇒ 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. Co-working offered flexible, shared office facilities to freelancers, technology start-ups, entrepreneurs, and nascent businesses that did not require or could not afford private workplaces. 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

Colonial Revival

During the late nineteenth century, a time of great tension, new immigration, and accelerating industrialization, white Euro-Americans sought comfort in the past, specifically the Colonial and Revolutionary eras. In their romanticized interpretation, the founding era was defined by simplicity, domestic industry, and unity—qualities in direct contrast to the tumultuous Civil War and its aftermath. They ⇒ 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. By the 1930s regional leaders had started to envision a larger maritime role for their new agency, but efforts to broaden its powers to include port operations were repeatedly ⇒ Read More

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

Dinosaurs and Paleontology (Study of Fossils and Prehistoric Life)

The Philadelphia area has played a major part in paleontology, the study of past life through fossils, yielding discoveries that have helped to illuminate millions of years of existence. In the early 1800s, Philadelphia became the birthplace of vertebrate paleontology, the study of ancient back-boned animals, and the Academy of Natural Sciences became a hub ⇒ 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. Once a small village surrounded by farms, Doylestown developed into a bustling borough with a thriving downtown, a university, two museums, and commuter rail that ⇒ Read More

Duffy’s Cut

At Duffy’s Cut, a railroad construction site in Chester County, Pennsylvania, fifty-seven Irish immigrant railroad workers died amid a cholera epidemic in the summer of 1832 and were buried in a mass grave. The Irishmen from Donegal, Tyrone, and Derry were hired to dig a railroad cut and construct an earthen fill in lieu of ⇒ Read More

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. In the years following World War II, people across the United States began to demand new measures to assure their health and safety. The resulting environmental movement, ⇒ Read More

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. To pay expenses and realize a profit from his enterprise, Penn had to sell land. 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. Traveling in a circle of trade across the north Atlantic, these goods forged relationships among ⇒ Read More

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.

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

Glassmakers and Glass Manufacturing

Glassmaking was one of Philadelphia’s earliest industries. Although it never became a major part of the city’s economy to the extent that industries such as textiles and metalworking did, a number of large glass manufacturers operated in and around Philadelphia from the early eighteenth to early twentieth centuries. The industry went into decline within 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

Great Wagon Road

Following routes established by Native Americans, the Great Wagon Road enabled eighteenth-century travel from Philadelphia and its hinterlands westward to Lancaster and then south into the backcountry of Maryland, Virginia, and North Carolina. In search of affordable farmland and economic opportunity, thousands of Scots Irish, Germans, and others left the Philadelphia region to establish farms, ⇒ 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.  They successfully launched autogiros, gyroplanes, and helicopters, and the Boeing Company paired with Bell Helicopters in Buffalo, New York, to produce the world’s first production tilt-rotor aircraft, the V-22 ⇒ Read More

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.

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.

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

Lawnside, New Jersey

Located approximately nine miles from Philadelphia and with a population of 2,995 as of 2010, Lawnside, New Jersey, has been one of only a handful of jurisdictions in the United States that has maintained a primarily African American population throughout its existence.

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.

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.

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.

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

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).

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.

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.

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.
