One of the three original counties created by William Penn in November 1682, and its name to him signified "brotherly love," although the original Philadelphia in Asia Minor was actually "the city of Philadelphus." Philadelphia was laid out in 1682 as the county seat and the capital of the Province; it was chartered as a city on October 25, 1701, and re-chartered on March 11, 1789. On February 2, 1854, all municipalities within the county were consolidated with the city. The county offices were merged with the city government in 1952.
See Old Philadelphia County, being a county overview from a textbook circa 1846, predating the consolidation.
There may have been even more municipalities that existed prior to consolidation. Tacony, for example, appears to have been a separate township prior to 1700.
Germantown, Moreland, Moyamensing, Northern Liberties, and Passyunk are each indicated on Holme's Map of 1687.
Germantown Boro was incorporated from part of German Township in 1691
Municipalities were being created and rearranged up until a short time before consolidation; West Philadelphia District was incorporated in 1852, and Belmont District in 1853.
