In the record
Ceded by the Kaskaskia at Vincennes in August 1803; the Piankishaw recognized their right to sell it in 1804, and the 1818 Edwardsville treaty confirmed and enlarged the cession. The area covers about 9.5 million acres in what is now Illinois.
The 1899 record names Kaskaskia as the people of this land.
How it was taken: a treaty or agreement. The OSU text records a negotiated cession with listed compensation; no cited source describes coercion, though the treaty text itself says the tribe had been reduced in number.
Today, Peoria Tribe of Indians of Oklahoma carries the history of the people named here.

Shapes come from C. C. Royce’s 1899 maps as georeferenced by the US Forest Service. They are approximate and are not legal descriptions of land. Royce recorded land the United States treated as ceded; the shape does not show a nation’s territory.
