For my CHI fellowship project, I will create a digital repository for materials relating to major Mississippian archaeological sites. The Mississippians were the most socially-complex peoples to ever inhabit prehistoric North America, and their sites generally date to between AD 1050 and AD 1500 (several groups in the Southeast United States continued to practice a Mississippian lifestyle at the time of European contact). Their lifeway was characterized by a ranked social structure with ascribed status differentiation, hierarchical inter-site political organization, ubiquitous cleared-field maize agriculture, and a set of common religious institutions and iconography. They dramatically modified their physical environments by clearing plazas and building earthen mounds of variable size and for various purposes, many of which are still evident on the landscape today. Mississippian groups inhabited an area spanning from northern Florida to Illinois and from the Atlantic plain to Eastern Oklahoma (though evidence of their influence is even more widespread).
