Broad Street

“No other street in America quite compares with Broad Street,” wrote E. Digby Baltzell, author of Puritan Boston and Quaker Philadelphia, of the varied architecture north and south of City Hall. Philadelphia’s Broad Street goes past stores, churches, synagogues, museums, funeral parlors, fast food places, gas stations, apartment houses, and rows and rows of row ⇒ Read More

Center City

Forming a core of civic, commercial, and residential life since Philadelphia’s seventeenth-century founding, Center City has been a continually evolving experiment in urban living and management. The roughly rectangular area of about 2.3 square miles between the Delaware and Schuylkill Rivers, from Vine Street to South Street, occupies the territory of the original 1682 city ⇒ 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

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

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

Fairmount Park

Fairmount Park was developed in the nineteenth century in an effort to protect Philadelphia’s public water supply and to preserve extensive green spaces within a rapidly industrializing cityscape. It became one of the largest urban riparian parks in the United States and comprises the largest contiguous components of Philadelphia’s public park system as administered by ⇒ Read More

Gayborhood

In the second half of the twentieth century, the Center City neighborhood that became known as the Gayborhood formed in the vicinity of Locust and Thirteenth Streets. The community and the geographical spaces it occupied played a vital role in the social and political struggles of LGBT (lesbian, gay, bisexual, and transgender) people locally and ⇒ 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

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

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

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

Lower Delaware Colonies (1609-1704)

The colonies that became the state of Delaware lay in the middle of the North American Atlantic coast, extending about 120 miles north from the Atlantic Ocean along the southwestern shore of the Delaware (South) Bay and River to within 10 miles of Philadelphia. Between 1609 and 1704, the area was a contested borderland between ⇒ 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

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. Originally surveyed by Englishmen Charles Mason (1728-86) and Jeremiah Dixon (1733-79), the line separates Pennsylvania from Maryland and West Virginia along the 39º43ˊ N. parallel and bounds Delaware along an arc that extends from ⇒ 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. They depended on the Philadelphia market to sell their products and on its port to connect them to the wider colonial world. Subsequent generations built a dense transportation network that linked county laborers, suppliers, ⇒ 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. As small and short-lived as it proved to be, New Sweden had ⇒ Read More

North Philadelphia

Where exactly North Philadelphia begins and ends is a matter of debate. Even native Philadelphians have difficulty identifying the boundaries of this area of their city with precision. This is likely because so many of the neighborhoods located north, northeast, or northwest of Philadelphia’s center enjoy common histories and developmental patterns and consequently look a ⇒ Read More

Northeast Philadelphia

From its initial, colonial foundations as a sparsely populated farming hinterland to its dramatic postwar housing development after World War II, Northeast Philadelphia developed into a desirable destination for those seeking to improve their economic, social, and cultural standing within Philadelphia’s city boundaries. Even as Northeast Philadelphia came to symbolize a middle-class environment rooted around homeownership, commercial development, and mass ⇒ Read More

Northwest Philadelphia

Northwest Philadelphia, bound loosely by the Roosevelt Expressway to the south, Broad Street to the east, and the suburbs of Montgomery County to the north and west, has origins as old as the city itself.  Developing around the Schuylkill and Wissahickon Creek waterways, and later Fairmount Park, the Northwest expanded and changed with the advent ⇒ Read More

Petty Island

Petty Island, part of Pennsauken, New Jersey, in the Delaware River opposite the Kensington section of Philadelphia, played a significant supporting role in the economic development of the region. Also known as “Pettys” or “Petty’s” Island, over time it served as a place where people hunted, fished, gathered herbs, farmed, built and repaired boats, operated ⇒ Read More

Philadelphia and Its People in Maps:
The 1790s

Philadelphia was the premier urban city in North America during the Early National era, a city so admired that people nicknamed it the “Athens of America.” Between 1790 and 1800, it was the official political capital of the United States.  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 founding Pennsylvania, William Penn (1644-1718) followed long-established precedent by dividing his ⇒ Read More

Pine Barrens

New Jersey’s Pine Barrens, the forest and wetlands area also known as the Pinelands or the Pines, have played a varied but vital role in the region’s cultural and economic history. The Pine Barrens have, over time, been a home to Native American populations, a center of early American industry, a hub of military activity, ⇒ 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

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

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

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

South Philadelphia

From the film Rocky (1976) to the Italian Market, South Philadelphia’s image as an urban village has been entwined with Italian immigration. While South Philadelphia’s large Italian immigrant community marked the neighborhood in many ways, an array of ethnic, racial, and religious groups have resided in South Philadelphia since the seventeenth century, making its history ⇒ Read More

South Street

Along its east-west course, South Street has been a space where different types of Philadelphians—white and black, poor and wealthy, parochial and urbane, straight and gay—have met and mingled. From its early days as a theater district, it evolved through various incarnations: from a locus for African American life to a center for immigrant-owned garment ⇒ Read More

Southwest Philadelphia

Southwest Philadelphia, which along with adjacent Tinicum Township, Delaware County, is the location of the Philadelphia International Airport, greets many visitors to the city. Yet, Southwest Philadelphia, often described as “far” Southwest, is quite possibly the least-known area of the city, even to Philadelphians. Kingsessing, as this vicinity was originally named, was the first section ⇒ 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

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

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

Trails (Recreational)

An expanding network of recreational paths for walkers, hikers, cyclists, joggers, and commuters serves the Greater Philadelphia region.  The first recreational paths date to the mid-nineteenth century, when upper-class residents sought idyllic walking grounds in rural cemeteries and urban parks. In the twentieth century, grassroots hiking clubs built additional footpaths, but by the early twenty-first ⇒ 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 New Jersey

Between 1674 and 1702, New Jersey was divided in half: The proprietary West New Jersey colony faced the Delaware River while East New Jersey looked toward the Hudson. Although this political division lasted less than three decades, it represented long-standing geographical orientations of the Lenape and Munsee native inhabitants and European colonists. Benjamin Franklin (1706-90) ⇒ 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
