Some of the Illinois people's prominent enemies were the Lakota (Sioux), Osage, Pawnee, and Arikara to the west and the Quapaw, Shawnee, and Chickasaw to the south. Although these tribes were consistent threats, the Iroquois became the most pressing enemy of the Illinois beginning in the late 1600s. The Iroquois, looking for new hunting grounds after exhausting their own resources, killed or captured many Illinois people through their war parties. This capture of land and people eventually pushed the Illinois out of the Great Lakes region and into present-day Kansas. Other than the internal conflict among the tribes themselves, the Illinois also faced threat from European forces that stirred conflict with them and started wars, some of in which the Illinois were recruited as allies.
