Utah Troubles (1857-58, 1881, 1915, 1941-1943) refers to a series of rebellions, reprisals, and occupations of the state of Utah by the United States Army. Starting in 1858, well before the War of Secession, Mormon nationalist-theocrats attempted several times to secede Utah from the Union and form the Nation of Deseret. The uprising of 1881, which coincided with the Second Mexican War tied future Utah uprisings to conflicts between the U.S. and the C.S., with the C.S. supporting the Mormons in each conflict thereafter.
