William Penn (1644- 1718) was an English writer and early Quaker who founded the colony of Pennsylvania under the power of the English monarchy. He was in charge of the organization and direction of the colony. He was also an early defender of democracy and religious freedom. He put in practice his democratic ideas in the way he ruled the colony, even though it was embodied in the English Empire ruled by an absolut king, and he could have exercised absolute powers too (as other governors did in their colonies).
He was among the first ones that promoted the union of all English colonies and the democratic principles set in the Pennsylvania Frame of Government were subsequently used as inspiration from the drafting the US Constitution.
