The Battle of Mount Zion Church was fought on December 28, 1861, in Boone County, near Mount Zion Church, during the American Civil War. The resulting Union victory here and elsewhere in central Missouri ended Confederate recruiting activities in the region and pushed conventional Confederate forces out of the area until the desperate fall 1864 invasion by General Sterling Price and his Missouri State Guard.
