Terrible Revolution is the history of apocalyptic visions in the Mormon experience. Christopher James Blythe follows how "last days" beliefs informed the Church of Jesus Christ of Latter-day Saints' relationship with the United States and how the role of lay visionaries in the tradition changed. Blythe's work draws on hundreds of little-known archival sources to capture, for the first time in scholarship, the 200-year history of Mormon apocalypticism.
