Cahokia
Cahokia was the largest city of the Mississippian culture. The Mississippian culture was found in what is now the Central and the Southeastern United States. The Mississippian culture began more than 1,000 years before European contact. The Mississippians were the people groups found in this area before the Native American tribes that the Europeans met beginning in the 1500s. Today, Cahokia is considered to be the largest and most complex city of its time north of the great cities in Mexico. Cahokia is very near present day St. Louis, Missouri. It is located on the east side of the Mississipi River in Illinois.
