Kansas City, Missouri, abbreviated KC or KCMO, is the largest city in the U.S. state of Missouri by population and area.

Kansas City was founded in the 1830s as a port on the Missouri and Kansas rivers. On June 1, 1850, the town of Kansas was incorporated; soon afterwards, a region designated as the Kansas Territory was established. Confusion between the city and the territory of Kansas ensued, so the name Kansas City was assigned to distinguish the city from the territory.

The 1838 Mormon War, also known as the Missouri Mormon War, was a series of armed conflicts between Mormons (Latter Day Saints) and other settlers in northern Missouri during the summer and fall of 1838. Initially characterized by mutual vigilante violence, it escalated into direct intervention by the Missouri state militia. The conflict concluded with the issuance of the Missouri Executive Order 44, which mandated the extermination or the expulsion of the Mormons from the state.

Early Latter Day Saints settled in Missouri driven by religious revelations instructing them to "gather" in Kirtland, Ohio, and Jackson County, Missouri. Facing increasing hostility from neighboring settlers, an 1833 crisis resulted in their forceful eviction from Jackson County by vigilantes. The Missouri legislature created Caldwell County in 1836 as a "compromise" for displaced Mormon settlers; however, the relocation of Mormon leaders from Kirtland in early 1838 intensified fears of Mormon consolidation and expansion in the state.
