Roger Williams, a 17th-century English immigrant to New England, was famously banished from the Massachusetts Bay Colony in 1635 for his "new and dangerous opinions" on religious freedom, the separation of church and state, and Indigenous land rights. Following his banishment, Williams settled the town of Providence with the permission of the Narragansett Sachems, creating a colony that was arguably the freest in the western world.
