Term: Sauk and Fox Treaty of 1804 (St. Louis)
Definition: Agreement negotiated with the Sauk and Fox that ceded to the U.S. nearly all of Wisconsin south of the Wisconsin River as well as most of Illinois; Black Hawk and other Sauk leaders later claimed this treaty was invalid because the Sauk negotiators had been in St. Louis on other business and had no authority to speak for the nation.
