Roger Williams, the founder of Rhode Island and an important American religious leader, arrives in Boston in the Massachusetts Bay Colony from England. Williams, a Puritan, worked as a teacher before serving briefly as a colorful pastor at Plymouth and then at Salem. Within a few years of his arrival, he alarmed the Puritan oligarchy of Massachusetts by speaking out against the right of civil authorities to punish religious dissension and to confiscate Indian land. In October 1635, he was banished from the Massachusetts Bay Colony by the General Court.
