Answer: The mid Atlantic colony of Pennsylvania was founded by William Penn primarily because of debt and religion.
Explanation: The mid Atlantic Colony of Pennsylvania was founded by William Penn on march 4th, 1681. The king, Charles II, owed Penn's father a large sum of money, and to pay that debt, he granted the Province of Pennsylvania to William Penn. (I guess Williams father had passed, so now he owed William instead ¯\_(ツ)_/¯ ) Anyway, after he was given the province of Pennsylvania, William founded a proprietary colony that provided a place of religious freedom for Quakers.
