Revolt in 2100 is a collection of a science fiction short novel and two short stories by Robert A. Heinlein. Part of Heinlein's Future History series, it was published in 1953.
This first part, "If This Goes On—", describes a secularist rebellion against an American theocracy and thus served as the vehicle for Heinlein to critique religious thinking, Protestant Christian fundamentalism, and Mormonism.
The other two parts, "Coventry" and "Misfit", describe the succeeding society from the point of view of characters who reject it.
