Rocky Boy Tribe of Chippewa Indians of Montana
May 10, 1868 Arapaho-Cheyenne Treaty
This treaty was signed at Fort Laramie, Dakota Territory (now Wyoming) on May 10, 1868. The treaty was about ceding their land in Nebraska, South Dakota, and Wyoming. Some of the Arapaho and Cheyenne (they are really Anishinabe) did agree to sign this treaty but they did not have the authority to do such. The government of the Anishinabe Nation had to sign the treaty to make the treaty legitimate. Many of the Arapaho and Cheyenne of Nebraska, South Dakota, and Wyoming (white historians refer to them as the northern Arapaho and northern Cheyenne) refused to sign this May 10, 1868 treaty. A decade later the United States waged a war against these Anishinabe people who did not sign the May 10, 1868 treaty. It is known as the Cheyenne Exodus of 1878. Below is the treaty agreements reached with those Arapaho and Cheyenne who signed the May 10, 1868 treaty.
