Red Cloud's War

Red Cloud's War was an armed conflict between the Lakota, Northern Cheyenne, and Northern Arapaho on one side and the United States in Wyoming and Montana territories from 1866 to 1868. The war was fought over control of the Powder River Country in north-central Wyoming. In 1863, European Americans had blazed the Bozeman Trail through the heart of the traditional territory of the Cheyenne, Arapaho, and Lakota. It was the shortest and easiest route from Fort Laramie and the Oregon Trail to the Montana gold fields. From 1864 to 1866, the trail was traversed by about 3,500 miners, emigrant settlers and others. The emigrants competed with the Indians for the diminishing resources near the trail. The United States named the war after Red Cloud, a prominent Oglala Lakota chief who led his followers in opposition to the presence of the U.S. military in the area. He was allied with the Cheyenne and Arapaho. With peace achieved under the Treaty of Fort Laramie in 1868, the Indians were victorious. They gained legal control of the Powder River country, although their victory would only endure for 8 years until the Great Sioux War of 1876.
