Philadelphia, Pennsylvania is a major city in the northeastern United States, founded in 1682 by William Penn as a planned colonial town and later central to revolutionary activity. The city served as a meeting place for delegates to the Continental Congress and was the site where the Declaration of Independence and the United States Constitution were debated and adopted.
