The biography traces Roger Williams from dissenting convictions through clashes with colonial authorities, banishment, and the founding of a colony that reflected his commitments to religious liberty and separation of church and state. It examines his theological and political writings, relations with Indigenous peoples and fellow settlers, and the controversies that affected his reputation. The narrative relies on unpublished letters, a facsimile of his handwriting, and other contemporary documents to reconcile conflicting accounts. The author seeks to reassess misconceptions about his character and to emphasize his sustained advocacy for freedom of conscience amid the turbulence of early New England settlement.
