The Treaties map shows the eight treaties that either ceded land in what is now northeastern Illinois or were negotiated at Chicago. It also highlights land that was never ceded by treaty. To get more information about each treaty or unceded land tract, simply click on the polygon, where we have included a short description and links to the treaty text and source maps.  Sources used for this map are listed within each treaty polygon.
