Answer:
Roger Williams founded the first permanent white settlement in Rhode Island at Providence in 1636 on land purchased from the Narragansett Indians. Forced to flee Massachusetts because of persecution, Williams established a policy of religious and political freedom in his new settlement.
Williams founded the colony of Rhode Island based upon principles of complete religious toleration, separation of church and state, and political democracy (values that the U.S. would later be founded upon). It became a refuge for people persecuted for their religious beliefs.
