Final answer:
William Penn's actions had a positive effect on colonial Americans by providing them with greater religious freedom and peace.
Step-by-step explanation:
William Penn's actions had a positive effect on colonial Americans by providing them with greater religious freedom and peace. After facing problems between Quaker and Anglican settlers, Penn proposed modifications to the colony's government that gave the assembly more power and underscored the religious freedom of the colonists. This structure lasted until the American Revolution and gave the residents far more control over the government than in any other English colony. As a result, colonial Americans enjoyed greater religious freedom and lived in a relatively peaceful environment.
