Utah War
In 1857–1858, the church was involved in an armed conflict with the U.S. government, entitled the Utah War. The settlers and the United States government battled for hegemony over the culture and government of the territory. Tensions over the Utah War, the murder of Mormon apostle Parley P. Pratt in Arkansas, and threats of violence from the Baker-Fancher wagon train (and possibly other factors), resulted in rogue Mormon settlers in southern Utah massacring a wagon train from Arkansas, known as Mountain Meadows massacre. The result of the Utah War was the succeeding of the governorship of the Utah territory from Brigham Young to Alfred Cumming, an outsider appointed by President James Buchanan.
