William Penn: Biography, Achievements & Lasting Legacy

William Penn (24 October [O.S. 14 October] 1644 – 10 August [O.S. 30 July] 1718) was an English writer, theologian, religious thinker, and influential Quaker who founded the Province of Pennsylvania. An advocate of democracy and religious freedom, Penn was known for his amicable relations and successful treaties with the Lenape native peoples who had resided in present-day Pennsylvania before European colonisation there.

In 1681, King Charles II granted an area of land corresponding to the present-day U.S. states of Pennsylvania and Delaware to Penn to offset debts he owed Penn's father, the admiral and politician Sir William Penn. The following year, Penn left England and sailed up Delaware Bay and the Delaware River, where he founded Philadelphia on the river's western bank. Penn's Quaker government was not viewed favorably by the Dutch, Swedish and English settlers in what is now Delaware, and the land was also claimed by the Calverts, proprietors of the neighbouring Province of Maryland. In 1704, the three southernmost counties of the province of Pennsylvania were granted permission to form a new, semi-autonomous Delaware Colony.

As one of the earliest supporters of colonial unification, Penn wrote and urged the union of all the British colonies into what would later become the United States. The democratic principles that he included in the West Jersey Concessions and outlined in the Pennsylvania Frame of Government inspired delegates to the 1787 Constitutional Convention in Philadelphia when they came to write the Constitution of the United States.

A man of deep religious conviction, Penn authored numerous works, exhorting believers to adhere to the spirit of Primitive Christianity. Penn was imprisoned several times in the Tower of London due to his faith. His book No Cross, No Crown, published in 1669 while he was in jail, has become a classic of Christian theological literature.
