The University of Illinois System – with its universities in Urbana-Champaign, Chicago, and Springfield – rests on the land of multiple native nations. These lands were the traditional birthright of indigenous peoples who were forcibly removed and who have faced two centuries of struggle for survival and identity in the wake of dispossession. We hereby acknowledge the ground on which we stand so that all who come here know that we recognize our responsibilities to the peoples of that land and that we strive to address that history so that it guides our work in the present and the future.
For more information on the University of Illinois System's land acknowledgment statement, see https://www.uillinois.edu/about/land_acknowledgement.
The following are collections of treaties and agreements made between Native American tribes and the U.S. government. Individual treaties are also printed in the U.S. Statutes at Large. Volume 7 of the Statutes at Large contains treaties between the "United States and the Indian Tribes" (1789-1845).
Note that the Library of Congress has a webpage that also focuses on treaties made between Native Americans and the American government and explains where to find them.
