Cahokia decline and Mississippian migration debate

Record summary

Late twentieth-century archaeological work at Cahokia examined the city’s decline, population movement, flooding, woodland depletion, political change, and regional reorganization after its Mississippian florescence. The case is relevant to catastrophe-and-migration comparisons because a large center’s transformation cannot be reduced automatically to one disaster or invasion. Researchers proposed combinations of environmental stress, social conflict, and changing exchange networks. Chronology and demographic estimates remain dependent on sampling, settlement surveys, and how archaeologists define “collapse” and abandonment.
