  With the British victory in the Seven Years' War, France in 1763 ceded to Britain its claims of North American territories east of the Mississippi River. Spain, in turn, gained rights to the territories west of Mississippi, which then served as a border between Spain and Britain's territorial claims. French colonists settled Illinois Country after several generations of experience on North America, migrating over the Mississippi River to regions where Spain was not present and where they were able to leverage their earlier Louisiana French settlements around the Gulf of Mexico. These early French settlers partnered with midwest indigenous tribes, and their mixed ancestry descendants later followed a westward expansion all the way to the Pacific Ocean on the present-day U.S. West Coast.
