Cahokia was an ancient Native American settlement located in the territory of what today is Illinois, approximately in 700AD. They were talented people capable of constructing those amazing and large mounds. Archeologists say that this place was the largest city north of México before the arrival of Christopher Columbus. They were known to be good traders that used the Mississippi River to navigate, transport people, and goods to other regions.
