Answer 4

Penn became convinced that religious toleration couldn't be achieved in England. He went to the King and asked for a charter enabling him to establish an American colony. Perhaps the idea seemed like an easy way to get rid of troublesome Quakers. On March 4, 1681, Charles II signed a charter for territory west of the Delaware River and north of Maryland, approximately the present size of Pennsylvania, where about a thousand Germans, Dutch and Indians lived without any particular government. The King proposed the name "Pennsylvania" which meant "Forests of Penn"--honoring Penn's late father, the Admiral. Penn would be proprietor, owning all the land, accountable directly to the King. According to traditional accounts, Penn agreed to cancel the debt of £16,000 which the government owed the Admiral for back pay, but there aren't any documents about such a deal. At the beginning of each year, Penn had to give the King two beaver skins and a fifth of any gold and silver mined within the territory.
