Mesoamerica
Mesoamerica was in the middle of America. They started as hunters and gathers but discovered that seeds grow into food, since they had rich volcanic soil. The people were called Olmec. The Olmec traded food for jewels and other metals.
Cahokia
The Mississippians lived here. This was the Mississippians largest city, with 30,000 people. Cahokia was in the Mississippi River valley. The Mississippians farmed corn, beans, and squash. They often lived on mounds of dirt.
