The Sioux Wars lasted from 1876-1877. These were spectacular clashes between the Sioux Indians and white men. They were spurred by gold-greedy miners rushing into Sioux land. The white men were breaking their treaty with the Indians. The Sioux Indians were led by Sitting Bull and they were pushed by Custer's forces. Custer led these forces until he was killed at the battle at Little Bighorn. Many of the Indian were finally forced into Canada, where they were forced by starvation to surrender.
