This ancient mound builder tribe lived in Illinois and Kentucky, in the area around where the Tennessee River empties into the Ohio River. Cahokia mounds and Angel Mounds may have been settled by them. Around 1650, a combination of climate, plagues, and war forced them to move across the Mississippi River into the Great Plains. They became the Dhegiha and split into 5 tribes: Omaha, Kaw/Kansa, Quapaw, Osage, Ponca.
