Philadelphia, located in Southeastern Pennsylvania, in the Mid-Atlantic region, is the fifth most-populous city in the United States. Often referred to as "Philly," the city is coterminous with Philadelphia County. Philadelphia sits adjacent to the New Jersey and Delaware borders, and as such, its metropolitan area encompasses counties in Pennsylvania, New Jersey and Delaware.
Philadelphia, often called the "Birthplace of America" and referred to as the "new Athens" early in its existence, is the birthplace of America's modern republic. Founded by William Penn in the late 17th century, the city's name translates to "City of Brotherly Love" and has been a seat of freedom since its inception; originally founded by Quakers, the colony promoted religious freedom among its residents in stark contrast to the England of the time.
