After the war, Edwards urged the federal government to remove the remaining Native Americans from northern Illinois, claiming that their presence violated "the rights of a sovereign and independent state", and hinting that he might dispatch the militia again to force them out. The federal government applied diplomatic pressure, and on July 29, 1829, the Potawatomi, Ottawa, and Ojibwe ceded of northern land to the State of Illinois; the Winnebago made a cession in August.
