Utah War

The Utah War, also known as the Utah Expedition, Utah Campaign, Buchanan's Blunder, the Mormon War, or the Mormon Rebellion was an armed confrontation between Mormon settlers in the Utah Territory and the armed forces of the United States government. The confrontation lasted from May 1857 until July 1858. While there were casualties, mostly non-Mormon civilians, the "war" had no battles, and was resolved through negotiation.
