Mississippian Indians
They were the last Indian culture to be in America. This included the Cherokee Indians. They still did NOT have a language but the prehistoric era did end when Hernando de Soto wrote stuff down in his diary. That broke the pre-historic era for the Americas. The Mississippian Indians were very stable and ate what ever was in their area. These people were near the sea board because of how nomadic previous cultures were. They became very intelligent and established a language and a government. They made a government just like The United States government. They also invented horticulture, the growing of food.
