On this day in 1635, Puritan minister Roger Williams was found guilty of spreading "newe & dangerous opinions" and banished from the Massachusetts Bay Colony. Before leaving England in 1630, Williams had seen heretics whipped, imprisoned, and burned at the stake. He called for religious freedom, a serious threat to the social order, and avoided arrest only by fleeing to Boston. Once in Massachusetts, he began preaching religious tolerance. The colony's leaders agreed with the English authorities that this was nothing less than "Satan's Policy." They denounced his views and forced him out of the colony. He took refuge with the Narragansett Indians, whose chiefs sold land to him and his followers. They established a new settlement and named it Providence, in thanksgiving to God.
