Twenty-six-year-old William Penn received from King Charles the charter to Pennsylvania on this date, March 10, 1681, as repayment of a debt owed to his deceased father. An Oxford graduate, Penn converted to Quakerism and was imprisoned in the Tower of London. His colony became a refuge for the persecuted peoples of Europe. Penn wrote to the Indians, whom he insisted on treating fairly: "My Friends, There is one ... God ... [and He] hath made ... the king of the country where I live, give ... unto me a great province therein, but I desire to enjoy it with your ... consent, that we may always live together as ... friends." History records that Penn's Colony never had an Indian attack.
