In relations with the white settlers all the divisions of the Sioux have a similar history. The Sioux became friendly with the British after the fall of the French power and supported the British against the United States in the American Revolution and (with the exception of one chief, Tohami, also known as Rising Moose) in the War of 1812. The United States concluded treaties with the Sioux in 1815, 1825, and 1851. A portion of the Sioux under Little Crow rose in 1862 and massacred more than 800 settlers and soldiers in Minnesota; this revolt was suppressed but unrest continued.
In 1867 a treaty was concluded by which the Sioux gave up a large section of territory and agreed to retire to a reservation in SW Dakota before 1876. The discovery of gold in the Black Hills and the subsequent rush of prospectors brought resistance under the leadership of such chiefs as Sitting Bull, Red Cloud, Rain-in-the-Face, Crazy Horse, American Horse, and Gall. In this revolt occurred the famous last stand by Gen. George Armstrong Custer. The last major conflict fought by the Sioux was the battle of Wounded Knee, Dec. 29, 1890, which resulted in the massacre of more than 200 members of the tribe.
