An excerpt from the article 22 facts about Philadelphia

Despite the edict, he purchased the land from the Delaware Indians to ensure peace for his colony. Local legend says that Penn made a pact of friendship with a Delaware chief under an elm tree in the Indian settlement of Shackamaxon (now Fishtown District).

William Penn was a member of the Quakers (a Christian religious community), he experienced religious persecution, so he wanted his colony to be a place of religious tolerance.
