<p>Philadelphia is the largest city in the Commonwealth of Pennsylvania and the county seat of Philadelphia County, with which it is coterminous. The city is located in the Northeastern United States along the Delaware and Schuylkill rivers. It is the fifth-most-populous city in the United States, with a population of 1,526,006 as of the 2010 U.S. Census. Philadelphia is also the commercial, cultural, and educational center of the Delaware Valley, home to 6 million people and the country's fifth-largest metropolitan area. The Philadelphia metropolitan division consists of five counties in Pennsylvania and has a population of 4,008,994. Popular nicknames for Philadelphia are Philly and The City of Brotherly Love, the latter of which comes from the literal meaning of the city's name in Greek.
</p><p>In 1682, William Penn founded the city to serve as a port and provincial capital. Philadelphia grew rapidly, and by the 1750s it was the largest city and busiest port in the original 13 American colonies. During the American Revolution, Philadelphia played an instrumental role as a meeting place for the Founding Fathers of the United States, who signed the nation's Declaration of Independence in 1776 and the Constitution in 1787. Philadelphia served as one of the nation's many capitals during the Revolutionary War, and the city served as the temporary national capital while Washington, D.C. was under construction. During the 19th century, Philadelphia became a major industrial center and railroad hub that grew from an influx of European immigrants. The city's dominant textile industry represented 40 percent of total U.S. output in 1906. It became a major destination for African Americans during the Great Migration and surpassed 2 million occupants by 1950.

The Delaware Valley contains the headquarters of thirteen Fortune 500 corporations, five of which are in Philadelphia proper.

Gentrification of Philadelphia's neighborhoods continues into the 21st century and the city has reversed its decades-long trend of population loss.
