About one thousand years ago, Native Americans built hundreds of earthen platform mounds, plazas, residential areas, and other types of monuments in the vicinity of present-day St. Louis. This sprawling complex, known to archaeologists as Cahokia, was the dominant cultural, ceremonial, and trade center north of Mexico for centuries. This stimulating collection of essays casts new light on the remarkable accomplishment of Cahokia. The nine contributors explore a wide range of topics - religion, trade, the nature of local and regional ideologies, social organization, subsistence, mound construction, and the longstanding question of Cahokia's relationship to later Mississippian chiefdoms across the Southeast.
