The Mormon War is a name sometimes given to the 1838 conflict which occurred between Latter Day Saints (Mormons) and their neighbors in the northwestern region of the US state of Missouri. This conflict is also sometimes referred to as the Missouri Mormon War to differentiate it from the Utah Mormon War (also known as the "Utah War") and the lesser known Illinois Mormon War. The conflict was preceded by the eviction of the Mormons from Jackson County, Missouri, in 1833. All of the conflicts in the Mormon War occurred in a corridor to the east and northeast of Kansas City, Missouri.
