Roger Williams, who preached religious tolerance, separation of church and state, and a complete break with the Church of England, was banished from Massachusetts and founded Rhode Island Colony, which became a haven for other religious refugees from the Puritan community. Some migrants who came to Colonial America were in search of the freedom to practice forms of Christianity which were prohibited and persecuted in Europe. Since there was no state religion, and since Protestantism had no central authority, religious practice in the colonies became diverse.
