History
Philadelphia, Bucks, and Chester were the three Pennsylvania counties initially created by William Penn on August 24, 1682. At that time, Chester County's borders were Philadelphia County to the north, the ill-defined western edge of the colony (approximately the Susquehanna River) to the west, the Delaware River to the east, and Delaware and Maryland to the south. Chester County replaced the Pennsylvania portion of New Netherland/New York’s "Upland", which was officially eliminated when Pennsylvania was chartered on March 4, 1681, but did not cease to exist until June of that year. Much of the Welsh Tract was in eastern Chester County, and Welsh place names, given by early settlers, continue to predominate there.
The original Chester County seat was the City of Chester, a center of naval shipbuilding, at the eastern edge of the county. In an effort to accommodate the increased population of the western part of the county, the county seat was moved to a more central location in 1788; in order to mollify the eastern portion of the county, the village, known as Turk's Head, was renamed West Chester. In response to the new location of the county seat, the eastern portion of the county separated and formed the new Delaware County in 1789 with the City of Chester as its county seat.
Much of the history of Chester County arises from its location between Philadelphia and the Susquehanna River. The first road to "the West" (meaning Lancaster County) passed through the central part of Chester County, following the Great Valley westward; with some re-alignments, it became the Lincoln Highway and later U.S. Route 30. This road is still named Lancaster Avenue in most of the Chester County towns it runs through. The first railroad (which became the Pennsylvania Railroad) followed much the same route, and the Reading Railroad progressed up the Schuylkill River to Reading. Industry tended to concentrate along the rail lines. Easy transportation allowed workers to commute to urban jobs, and the rise of the suburbs followed. To this day, the developed areas form "fingers" extending along major lines of transportation.
During the American Revolutionary War, the Battle of Brandywine was fought at what is now the southeastern fringe of the county. The Valley Forge encampment was at the northeastern edge.
