Red Cloud's War was a conflict that took place from 1866 to 1868 between the United States Army and the Lakota Sioux, led by Chief Red Cloud. This war was significant as it represented one of the first instances in which Native American forces successfully united to resist U.S. expansion into their territories, leading to the Treaty of Fort Laramie in 1868 that recognized Lakota sovereignty over the Black Hills.
