Agreement at Fort Berthold, 1866 and Addenda.

This 1904 reprint of the unratified treaty with the Arikara, Mandan, and Hidatsa, was reprinted as the Agreement at Fort Berthold, 1866, in vol. II of Charles Kappler’s Indian Affairs. Laws and Treaties. Originally signed on July 27, 1866, at Fort Berthold, Dakota Territory, this treaty and its Addenda were a set of agreements between the US government and representatives of the Arikara, Mandan, and Hidatsa Nations. In this document, the Arikara, Mandan, and Hidatsa agreed to cede a portion of their land on the east bank of the Missouri River and granted a right-of-way for roads through their land in return for annuities and other payments. Notably, this treaty is among the first documents to recognize the Mandan, Hidatsa, and Arikara as being united and acting in common with the United States.https://commons.und.edu/indigenous-gov-docs/1016/thumbnail.jp
