Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia.

Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's independence. Philadelphia hosted the First Continental Congress in 1774 following the Boston Tea Party, preserved the Liberty Bell, and hosted the Second Continental Congress during which the founders signed the Declaration of Independence, which historian Joseph Ellis has described as "the most potent and consequential words in American history". Once the Revolutionary War commenced, both the Battle of Germantown and the Siege of Fort Mifflin were fought within Philadelphia's city limits. The U.S. Constitution was later ratified in Philadelphia at the Philadelphia Convention of 1787. Philadelphia remained the nation's largest city until 1790, when it was surpassed by New York City, and served as the nation's first capital from May 10, 1775, until December 12, 1776, and on four subsequent occasions during and following the American Revolution, including from 1790 to 1800 while the new national capital of Washington, D.C., was under construction.

With 18 four-year universities and colleges, Philadelphia is one of the nation's leading centers for higher education and academic research. , the Philadelphia metropolitan area was the nation's ninth-largest metropolitan economy with a gross metropolitan product (GMP) of US$479 billion. Philadelphia is the largest center of economic activity in Pennsylvania and the broader multi-state Delaware Valley region; the city is home to five Fortune 500 corporate headquarters as of 2022. The Philadelphia skyline, which includes several globally renowned commercial skyscrapers, is expanding, primarily with new residential high-rise condominiums. The city and the Delaware Valley are a biotechnology and venture capital hub; and the Philadelphia Stock Exchange, owned by NASDAQ, is the nation's oldest stock exchange and a global leader in options trading. 30th Street Station, the city's primary rail station, is the third-busiest Amtrak hub in the nation, and the city's multimodal transport and logistics infrastructure, including Philadelphia International Airport, the PhilaPort seaport, freight rail infrastructure, roadway traffic capacity, and warehouse storage space, are all expanding.

Philadelphia is a national cultural hub, hosting more outdoor sculptures and murals than any other American city. Fairmount Park, when combined with adjacent Wissahickon Valley Park in the same watershed, is , representing one of the nation's largest contiguous urban parks and the 45th largest urban park in the world. The city is known for its arts, culture, cuisine, and colonial and Revolution-era history; in 2016, it attracted 42 million domestic tourists who spent $6.8 billion, representing $11 billion in total economic impact to the city and surrounding Pennsylvania counties.

With five professional sports teams and a hugely loyal fan base, the city is often ranked as the nation's best city for professional sports fans. The city has a culturally and philanthropically active LGBTQ+ community. Philadelphia also has played an immensely influential historic and ongoing role in the development and evolution of American music, especially R&B, soul, and rock.

Philadelphia is a city of many firsts, including the nation's first library (1731), hospital (1751), medical school (1765), national capital (1774), university (by some accounts) (1779), stock exchange (1790), zoo (1874), and business school (1881). Philadelphia contains 67 National Historic Landmarks, including Independence Hall. From the city's 17th century founding through the present, Philadelphia has been the birthplace or home to an extensive number of prominent and influential Americans. In 2021, ''Time'' magazine named Philadelphia one of the world's greatest 100 places.

History

Native peoples

Prior to the arrival of Europeans in the early 17th century, the Philadelphia area was home to the Lenape (Delaware) Indians in the village of Shackamaxon. They were also called the Delaware Indians,Josephy 188–189 and their historical territory was along the Delaware River watershed, western Long Island, and the Lower Hudson Valley. Most Lenape were pushed out of their Delaware homeland during the 18th century by expanding European colonies, exacerbated by losses from intertribal conflicts. Lenape communities were weakened by newly introduced diseases, mainly smallpox, and conflict with Europeans. The Iroquois occasionally fought the Lenape. Surviving Lenape moved west into the upper Ohio River basin. The American Revolutionary War and the United States' independence pushed them further west. In the 1860s, the United States government sent most Lenape remaining in the eastern United States to the Indian Territory (present-day Oklahoma and surrounding territory) under the Indian removal policy.

Colonial

Europeans came to the Delaware Valley in the early 17th century, with the first settlements founded by Dutch colonists, who in 1623 built Fort Nassau on the Delaware River in what is now Brooklawn, New Jersey colony. In 1638, Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina (present-day Wilmington, Delaware) and quickly spread out in the valley. In 1644, New Sweden supported the Susquehannocks in their war against Maryland colonists. In 1648, the Dutch built Fort Beversreede on the west bank of the Delaware, south of the Schuylkill River near the present-day Eastwick neighborhood, to reassert their dominion over the area. The Swedes responded by building Fort Nya Korsholm, or New Korsholm, named after a town in Finland with a Swedish majority. In 1655, a Dutch military campaign led by New Netherland Director-General Peter Stuyvesant took control of the Swedish colony, ending its claim to independence. The Swedish and Finnish settlers continued to have their own militia, religion, and court, and to enjoy substantial autonomy under the Dutch. An English fleet captured the New Netherland colony in 1664, though the situation did not change substantially until 1682, when the area was included in William Penn's charter for Pennsylvania.

In 1681, in partial repayment of a debt, Charles II of England granted Penn a charter for what would become the Pennsylvania colony. Despite the royal charter, Penn bought the land from the local Lenape to be on good terms with the Native Americans and ensure peace for his colony. Penn made a treaty of friendship with Lenape chief Tammany under an elm tree at Shackamaxon, in what is now the city's Fishtown neighborhood. Penn named the city Philadelphia, which is Greek for "brotherly love," derived from the Ancient Greek terms φίλος ''phílos'' (beloved, dear) and ἀδελφός ''adelphós'' (brother, brotherly). There were a number of cities named ''Philadelphia'' in the Eastern Mediterranean during the Greek and Roman periods, including one (modern Alaşehir) mentioned as the site of an early Christian congregation in the Book of Revelation. As a Quaker, Penn had experienced religious persecution and wanted his colony to be a place where anyone could worship freely. This tolerance, far more than afforded by most other colonies, led to better relations with the local native tribes and fostered Philadelphia's rapid growth into America's most important city.

Penn planned a city on the Delaware River to serve as a port and place for government. Hoping that Philadelphia would become more like an English rural town instead of a city, Penn laid out roads on a grid plan to keep houses and businesses spread far apart, with areas for gardens and orchards.

The city's inhabitants did not follow Penn's plans, however, as they crowded by the present-day Port of Philadelphia on the Delaware River, and subdivided and resold their lots. Before Penn left Philadelphia for the last time, he issued the Charter of 1701 establishing it as a city. Though poor at first, the city became an important trading center with tolerable living conditions by the 1750s. Benjamin Franklin, a leading citizen, helped improve city services and founded new ones, such as fire protection, a library, and one of the American colonies' first hospitals.

A number of philosophical societies were formed, which were centers of the city's intellectual life: the Philadelphia Society for Promoting Agriculture (1785), the Pennsylvania Society for the Encouragement of Manufactures and the Useful Arts (1787), the Academy of Natural Sciences (1812), and the Franklin Institute (1824). These societies developed and financed new industries, attracting skilled and knowledgeable immigrants from Europe.

Revolution

Philadelphia's importance and central location in the colonies made it a natural center for America's revolutionaries. By the 1750s, Philadelphia had surpassed Boston as the largest city and busiest port in British America, and the second-largest city in the entire British Empire, after London. Before the Revolutionary War, in 1774, as resentment of British colonial practices and support for independence was burgeoning in the colonies, Philadelphia hosted the First Continental Congress. From 1775 to 1781, Philadelphia hosted the Second Continental Congress, which adopted the Declaration of Independence in what was then called the Pennsylvania State House and now is called Independence Hall, on July 4, 1776.

Historian Joseph Ellis, in 2007, described the Declaration of Independence as "the most potent and consequential words in American history," and its adoption represented a declaration of war, already ongoing since April 1775, against the British Army, which was then the most powerful military force in the world. Since the Declaration's July 4, 1776, adoption, its signing has been cited globally and repeatedly by various peoples of the world seeking independence and liberty. It also has been, since its adoption, the basis for annual celebration by Americans; in 1938, this celebration of the Declaration was formalized as Independence Day, one of only ten designated U.S. federal holidays.

After George Washington's defeat at the Battle of Brandywine in Chadds Ford Township, Pennsylvania on September 11, 1777, the revolutionary capital of Philadelphia was defenseless. The city prepared for what was perceived to be an inevitable British Army attack. Because bells could easily be recast into munitions, the Liberty Bell, then known as the Pennsylvania State Bell, along with bells from two Philadelphia churches, Christ Church and St. Peter's Church, were hastily taken down and transported by heavily-guarded wagon train out of the city. The Liberty Bell was taken to Zion German Reformed Church in Northampton Town (present-day Allentown), where it was hidden under the church's floor boards for nine months, from September 1777 until the British Army's departure from Philadelphia in June 1778, during the British occupation of Philadelphia. Two Revolutionary War battles, the Siege of Fort Mifflin (September 26 to November 16, 1777) and the Battle of Germantown (October 4, 1777), were both fought within Philadelphia's city limits.

In Philadelphia, the Second Continental Congress adopted the Articles of Confederation on November 15, 1777, and the city later served as the meeting place for the Constitutional Convention, which ratified the Constitution in Independence Hall in Philadelphia on September 17, 1787.

Philadelphia served as capital of the United States for much of the colonial and early post-colonial periods, including for a decade, from 1790 to 1800, while the District of Columbia was being constructed and prepared to serve as the new nation's national capital. In 1793, the largest yellow fever epidemic in U.S. history killed approximately 4,000 to 5,000 people in Philadelphia, or about 10% of the city's population.

The state capital was moved to Lancaster in 1799, then Harrisburg in 1812, while the federal government was moved to Washington, D.C., in 1800 upon completion of the White House and U.S. Capitol building. Philadelphia remained the young nation's largest city until the late 18th century, serving as the nation's financial and cultural center, until ultimately being eclipsed in total population by New York City in 1790. In 1816, the city's free Black community founded the African Methodist Episcopal Church (AME), the first independent Black denomination in the country, and the first Black Episcopal Church. The free black community also established many schools for its children, with the help of Quakers. Large-scale construction projects for new roads, canals, and railroads made Philadelphia the first major industrial city in the United States.

19th century

Throughout the 19th century, Philadelphia hosted a variety of industries and businesses, the largest being textiles. Major corporations in the 19th and early 20th centuries included the Baldwin Locomotive Works, William Cramp & Sons Shipbuilding Company, and the Pennsylvania Railroad. Established in 1870, the Philadelphia Conveyancers' Association was chartered by the state in 1871. Industry, along with the U.S. Centennial, was celebrated in 1876 with the Centennial Exposition, the first official World's fair in the United States.

Immigrants, mostly from Ireland and Germany, settled in Philadelphia and the surrounding districts. These immigrants were largely responsible for the first general strike in North America in 1835, in which workers in the city won the ten-hour workday. The city was a destination for thousands of Irish immigrants fleeing the Great Famine in the 1840s; housing for them was developed south of South Street and later occupied by succeeding immigrants. They established a network of Catholic churches and schools and dominated the Catholic clergy for decades. Anti-Irish, anti-Catholic nativist riots erupted in Philadelphia in 1844. The rise in population of the surrounding districts helped lead to the Act of Consolidation of 1854, which extended the city limits from the of Center City to the roughly of Philadelphia County.
In the latter half of the 19th century and leading into the 20th century, immigrants from Russia, Eastern Europe, and Italy, and African Americans from the southern U.S. settled in the city.

Philadelphia was represented by the Washington Grays in the American Civil War. The African-American population of Philadelphia increased from 31,699 to 219,559 between 1880 and 1930. Twentieth-century black newcomers were part of the Great Migration out of the rural south to northern and midwestern industrial cities.

20th century

By the 20th century, Philadelphia had an entrenched Republican political machine and a complacent population. The first major reform came in 1917 when outrage over the election-year murder of a police officer led to the shrinking of the City Council from two houses to just one. In July 1919, Philadelphia was one of more than 36 industrial cities nationally to suffer a race riot of ethnic whites against blacks during Red Summer, in post-World War I unrest, as recent immigrants competed with blacks for jobs. In the 1920s, the public flouting of Prohibition laws, organized crime, mob violence, and police involvement in illegal activities led to the appointment of Brig. Gen. Smedley Butler of the U.S. Marine Corps as director of public safety, but political pressure prevented any long-term success in fighting crime and corruption.

In 1940, non-Hispanic whites constituted 86.8% of the city's population. The population peaked at more than two million residents in 1950, then began to decline with the restructuring of industry, which led to the loss of many middle-class union jobs. In addition, suburbanization had enticed many of the more affluent residents to outlying railroad commuting towns and newer housing. The resulting reduction in Philadelphia's tax base and the resources of local government caused the city to struggle through a long period of adjustment, with it approaching bankruptcy by the late 1980s.

Revitalization and gentrification of neighborhoods began in the late 1970s and continues into the 21st century, with much of the development occurring in the Center City and University City neighborhoods, while simultaneously exacerbating a shortage of affordable housing in Philadelphia. After many of the old manufacturers and businesses left Philadelphia or shut down, the city started attracting service businesses and began to market itself more aggressively as a tourist destination. Contemporary glass-and-granite skyscrapers were built in Center City beginning in the 1980s. Historic areas such as Old City and Society Hill were renovated during the reformist mayoral era of the 1950s through the 1980s, making those areas among the most desirable neighborhoods in Center City. Many immigrants from around the world began to enter the U.S. through Philadelphia as their gateway. These developments led to a reversal of the city's population decline between 1950 and 2000, during which it lost about 25 percent of its residents.

21st century

Philadelphia eventually began experiencing a growth in its population in 2007, which continued with gradual yearly increases through the present. Although Philadelphia is rapidly undergoing gentrification, the city maintains strategies to minimize displacement of homeowners in gentrifying neighborhoods.

Geography

Topography

The geographic center of Philadelphia is about 40° 0′ 34″ north latitude and 75° 8′ 0″ west longitude. The 40th parallel north passes through neighborhoods in Northeast Philadelphia, North Philadelphia, and West Philadelphia including Fairmount Park. The city encompasses , of which is land and , or 6%, is water. Natural bodies of water include the Delaware and Schuylkill rivers, the lakes in Franklin Delano Roosevelt Park, and Cobbs, Wissahickon, and Pennypack creeks. The largest artificial body of water is the East Park Reservoir in Fairmount Park.

The lowest point is sea level, while the highest point is in Chestnut Hill, about above sea level on Summit Street near the intersection of Germantown Avenue and Bethlehem Pike (example coordinates near high point: 40.07815 N, 75.20747 W).

Philadelphia is situated on the Fall Line that separates the Atlantic coastal plain from the Piedmont. The rapids on the Schuylkill River at East Falls were inundated by the completion of the dam at the Fairmount Water Works.

The city is the seat of its own county. The adjacent counties are Montgomery to the northwest; Bucks to the north and northeast; Burlington County, New Jersey, to the east; Camden County, New Jersey, to the southeast; Gloucester County, New Jersey, to the south; and Delaware County to the southwest.

Cityscape

City planning

Philadelphia's central city was created in the 17th century following the plan by William Penn's surveyor Thomas Holme. Center City is structured with long, straight streets running nearly due east–west and north–south, forming a grid pattern between the Delaware and Schuylkill rivers that is aligned with their courses. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire. In keeping with the idea of a "Greene Countrie Towne", and inspired by the many types of trees that grew in the region, Penn named many of the east–west streets for local trees. Penn planned the creation of five public parks in the city which were renamed in 1824 (new names in parentheses): Centre Square (Penn Square), Northeast Square ( Franklin Square), Southeast Square ( Washington Square), Southwest Square (Rittenhouse Square), and Northwest Square ( Logan Circle/Square). Center City had an estimated 183,240 residents , making it the second-most populated downtown area in the United States, after Midtown Manhattan in New York City.

Philadelphia's neighborhoods are divided into large sections—North, Northeast, South, Southwest, West, and Northwest—surrounding Center City, which correspond closely with the city's limits before consolidation in 1854. Each of these large areas contains numerous neighborhoods, some of whose boundaries derive from the boroughs, townships, and other communities that constituted Philadelphia County before their inclusion within the city.

The City Planning Commission, tasked with guiding growth and development of the city, has divided the city into 18 planning districts as part of the ''Philadelphia2035'' physical development plan. Much of the city's 1980 zoning code was overhauled from 2007 to 2012 as part of a joint effort between former mayors John F. Street and Michael Nutter. The zoning changes were intended to rectify incorrect zoning maps to facilitate future community development, as the city forecasts an additional 100,000 residents and 40,000 jobs will be added by 2035.

The Philadelphia Housing Authority (PHA) is the largest landlord in Pennsylvania. Established in 1937, the PHA is the nation's fourth-largest housing authority, serving about 81,000 people with affordable housing, while employing 1,400 on a budget of $371 million. The Philadelphia Parking Authority works to ensure adequate parking for city residents, businesses, and visitors.

Architecture

Philadelphia's architectural history dates back to colonial times and includes a wide range of styles. The earliest structures were constructed with logs, but brick structures were common by 1700. During the 18th century, the cityscape was dominated by Georgian architecture, including Independence Hall and Christ Church.

In the first decades of the 19th century, Federal and Greek Revival architecture were the dominant styles produced by Philadelphia architects such as Benjamin Latrobe, William Strickland, John Haviland, John Notman, Thomas Walter, and Samuel Sloan. Frank Furness is considered Philadelphia's greatest architect of the second half of the 19th century. His contemporaries included John McArthur Jr., Addison Hutton, Wilson Eyre, the Wilson Brothers, and Horace Trumbauer. In 1871, construction began on the Second Empire-style Philadelphia City Hall. The Philadelphia Historical Commission was created in 1955 to preserve the cultural and architectural history of the city. The commission maintains the Philadelphia Register of Historic Places, adding historic buildings, structures, sites, objects and districts as it sees fit.

In 1932, Philadelphia became home to the first modern International Style skyscraper in the United States, the PSFS Building, designed by George Howe and William Lescaze. The City Hall remained the tallest building in the city until 1987 when One Liberty Place was completed. Numerous glass and granite skyscrapers were built in Center City beginning in the late 1980s. In 2007, the Comcast Center surpassed One Liberty Place to become the city's tallest building. The Comcast Technology Center was completed in 2018, reaching a height of , as the tallest building in the United States outside of Manhattan and Chicago.

For much of Philadelphia's history, the typical home has been the row house. The row house was introduced to the United States via Philadelphia in the early 19th century and, for a time, row houses built elsewhere in the United States were known as "Philadelphia rows". A variety of row houses are found throughout the city, from Federal-style continuous blocks in Old City and Society Hill to Victorian-style homes in North Philadelphia to twin row houses in West Philadelphia. While newer homes have been built recently, much of the housing dates to the 18th, 19th and early 20th centuries, which has created problems such as urban decay and vacant lots. Some neighborhoods, including Northern Liberties and Society Hill, have been rehabilitated through gentrification.

Fairmount Park, when combined with Wissahickon Valley Park, is one of the largest contiguous urban park areas in the United States. The two parks, along with the Colonial Revival, Georgian and Federal-style mansions contained in them, have been listed as one entity on the National Register of Historic Places since 1972.

Climate

According to the Köppen climate classification, Philadelphia falls under the northern periphery of the humid subtropical climate zone (Köppen ''Cfa''), whereas according to the Trewartha climate classification, the city has a temperate maritime climate (''Do'') limited to the north by the continental climate (''Dc'').

Air quality

Philadelphia County received an ozone grade of F and a 24-hour particle pollution rating of D in the American Lung Association's 2017 State of the Air report, which analyzed data from 2013 to 2015. The city was ranked 22nd for ozone, 20th for short-term particle pollution, and 11th for year-round particle pollution. According to the same report, the city experienced a significant reduction in high ozone days since 2001—from nearly 50 days per year to fewer than 10—along with fewer days of high particle pollution since 2000—from about 19 days per year to about 3—and an approximate 30% reduction in annual levels of particle pollution since 2000. Five of the ten largest combined statistical areas (CSAs) were ranked higher for ozone: Los Angeles (1st), New York City (9th), Houston (12th), Dallas (13th), and San Jose (18th). Many smaller CSAs were also ranked higher for ozone including Sacramento (8th), Las Vegas (10th), Denver (11th), El Paso (16th), and Salt Lake City (20th); however, only two of those same ten CSAs—San Jose and Los Angeles—were ranked higher than Philadelphia for both year-round and short-term particle pollution.
