This treaty, signed on July 30, 1825, was the first major treaty between the US Government and representatives of the Mandan Nation. Also known as the Atkinson and O'Fallon Trade and Intercourse Treaty of 1825, this document was part of a series of friendship treaties between Henry Atkinson and Benjamin O’Fallon’s Indian Peace Commission and the Indigenous Nations beyond the Mississippi River. In this treaty, the Mandan acknowledged the supremacy of the United States, which successively promised them peace, friendship, and protection. The Mandan also admitted that they resided within the territorial limits of the United States and that it had the right to regulate all trade and intercourse with them. The treaty further states that the Mandan agreed to use the laws of the United States to prevent or redress any injuries done by individuals, both American and Indigenous.
