The Kickapoo people are an Algonquian-speaking Native American and Indigenous Mexican tribe, originating in the region south of the Great Lakes. Today, three federally recognized Kickapoo tribes are in the United States: the Kickapoo Tribe in Kansas, the Kickapoo Tribe of Oklahoma, and the Kickapoo Traditional Tribe of Texas. The Oklahoma and Texas bands are politically associated with each other. The Kickapoo in Kansas came from a relocation from southern Missouri in 1832 as a land exchange from their reserve there. Around 3,000 people are enrolled tribal members.

The Treaty of Fort Wayne, sometimes called the Ten O'clock Line Treaty or the Twelve Mile Line Treaty, is an 1809 treaty that obtained 29,719,530 acres of Native American land for the settlers of Illinois and Indiana. The negotiations primarily involved the Delaware tribe but included other tribes as well. However, the negotiations excluded the Shawnee, who were minor inhabitants of the area and had previously been asked to leave by Miami War Chief Little Turtle. Territorial Governor William Henry Harrison negotiated the treaty with the tribes. The treaty led to a war with the United States begun by Shawnee leader Tecumseh and other dissenting tribesmen in what came to be called "Tecumseh's War".
