Answer: “ On this day in 1682, the fifth Duke of York (1633-1701), the son of England’s Charles I, awarded William Penn (1644-1718) a deed to the three counties that now make up the state of Delaware. Penn, a Quaker leader and an advocate of religious freedom, oversaw the founding of the Commonwealth of Pennsylvania as a refuge for Quakers and other religious minorities.
Penn successfully sought to acquire the tract — which had been transferred from Dutch to British authority — to ensure access to the Atlantic Ocean for the new colony.
