Before this time, William Penn had become the principal owner of the West Jersey interest. Not long afterwards (1681), by surrendering a claim which his father held against the British government, Penn procured from King Charles II. a much greater proprietary domain, on the western side of the Delaware, being no less than the vast tract, 40,000 square miles in extent, which received the name of Pennsylvania. To his title from the king he added a deed of purchase from the Indians. Penn's scheme of colonization was very liberally framed, and it was conducted with marked success. Philadelphia, first laid out in 1683, had 2,000 inhabitants in 1685, and Pennsylvania at large had 8,000. Penn himself did not find peace or happiness in his position as a princely proprietor; but he founded a great and prosperous commonwealth on noble lines. See PENNSYLVANIA. In order to possess one bank of the Delaware River and Bay to the sea, William Penn, after securing his grant from the king, bought additionally from the Duke of York the claims of the latter to that strip of territory which the Swedes had settled on and struggled for with the Dutch, and which took an independent political form in later days as the State of Delaware. The Delaware "territories," as they were called, never accepted their dependent relationship to Pennsylvania, and as early as 1702 it was found necessary to concede them a separate legislature, though they continued under Penn's proprietary government.
