The borough of Swarthmore, a little over a square mile in area and located in Delaware County, was incorporated in 1893. The impetus for its transition from a rural hamlet into a thriving, broad-based community came from the founding in 1864 of Swarthmore College, a coeducational college founded by members of the Society of Friends (Quakers). Access to quality roads and public transportation encouraged its growth in the late 19th century and 20th century. The 21st century finds Swarthmore the home of one of the best liberal arts colleges in America, ideally situated in suburban Philadelphia while retaining its historic residential character and strong identity.
