In 1865 Utah's Black Hawk War erupted when an incident between a Manti resident and a young chieftain exploded into open warfare between the Mormon settlers and the local Native Americans. Forts were built in Manti and other nearby communities. Smaller settlements in the area were temporarily abandoned for the duration of the war. In the fall of 1867, Chief Black Hawk made peace with the settlers, but sporadic violence occurred until 1872 when federal troops intervened. Many Mormon settlers who fought and died in the wars are buried in the Manti Cemetery. Most of the Utes were eventually relocated to the Uintah and Ouray Indian Reservation in Eastern Utah.
