Had Brigham Young not migrated large groups to Utah, the Mormons would have dispersed into minor sects like the RLDS, now Community of Christ. Once they became established in Utah, though, there was no turning back. The Mormons were too valuable in westward settlement, especially by the time of the transcontinental railroad. They themselves had too much to lose if they fought too hard. Fundamentalist Mormons could have moved farther into frontier areas, out of sight.
