 Increasing territorial conflict between the Sioux and the Ojibwe on the western frontier , particularly along the Mississippi river , led the U.S. government to attempt to mediate the conflicts . President Andrew Jackson 's policy toward the tribes ultimately was to either <unk> them sufficiently to allow westward expansion of American settlers , or else remove the tribes from the areas in which they prevented settlement . The First Treaty of Prairie du Chien ( 1825 ) , among its provisions established southern Minnesota as well as much of modern North and South Dakota as the homeland of the Dakota Sioux . The Ojibwe were given northern Minnesota and much of Wisconsin . The U.S. government , though , failed to enforce the treaty agreements leading to Little Crow 's <unk> to Indian agent Taliaferro in 1829 : " We made peace to please you , but if we are badly off we must blame you for causing us to give up so much of our lands to our enemies .
