Which US city is known as the City of Brotherly Love?

Philadelphia, known colloquially as Philly, is the largest city in the U.S. state and Commonwealth of Pennsylvania, and the sixth-most populous U.S. city. William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 at the Second Continental Congress, and the Constitution at the Philadelphia Convention of 1787. Other several key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress, the preservation of the Liberty Bell, the Battle of Germantown, and the Siege of Fort Mifflin.

Philadelphia has long been nicknamed "The City of Brotherly Love" or "The City of Brotherly Love and Sisterly Affection" from the literal meaning of the city's name in Greek, derived from the Ancient Greek terms "phílos" (beloved, dear, or loving) and "adelphós" (brother, brotherly). The city was first named by its founder, William Penn.
