Mississippian culture is the culture of the Mississippian people. They were Native Americans who lived in the Mississippi River Valley. Around 900–1450 AD, the Mississippian culture developed and spread through the Eastern United States. Mississippian people were most often farmers who settled into river valleys and grew the "three sisters" of corn, beans and squash.
