William Penn (1644–1718) dedicated his life to establishing a utopian colony governed by Quaker principles — what he called his "Holy Experiment."
King Charles II owed £16,000 to Penn's father, Admiral Sir William Penn. In 1681, the debt was settled with a charter for 45,000 sq mi west of the Delaware River — named Pennsylvania ("Penn's Woods") by the king.
Boundary disputes (Maryland, New York), financial losses, political betrayals, and later proprietary conflicts diluted the experiment. Penn died in debt.
Pennsylvania became the most religiously diverse, politically progressive, and economically vibrant colony. Its principles influenced the U.S. Constitution. The "Holy Experiment" remains a touchstone for pluralism and peaceful coexistence.
