The United States’ oldest great civilization: Cahokia?
When we studied Native American history in school, we learned about many tribes. Chances are you don’t remember learning of Cahokia, a long-extinct civilization originally near what is now Collinsville, Illinois. First established around AD 600 and inhabited by a unique indigenous people, Cahokia was a civilization comprised of about 50 communities over 2,200 acres.
They built 120 earth mounds – some over ten stories tall – in the largest prehistoric earthen construction site north of Mexico. The Cahokians were advanced people who did not appear to be related to any major known Native American tribes. By 1250, Cahokia’s population rivaled Paris and London; at its peak in 1300, Cahokia numbered an estimated 40,000 people. It wasn’t until 1800 that a modern U.S. city would finally surpass that number.
After 1300, the population declined for unknown reasons and the city would lie vacant for another century.
