Using fresh evidence and nontraditional ideas, the contributing authors of Mississippian Beginnings reconsider the origins of the Mississippian culture of the North American Midwest and Southeast (A.D. 1000–1600). Challenging the decades-old opinion that this culture evolved similarly across isolated Woodland populations, they discuss signs of migrations, missionization, pilgrimages, violent conflicts, long-distance exchange, and other far-flung entanglements that now appear to have shaped the early Mississippian past. Presenting recent fieldwork from a wide array of sites including Cahokia and the American Bottom, archival studies, and new investigations of legacy collections, the contributors interpret results through contemporary perspectives that emphasize agency and historical contingency. They track the various ways disparate cultures across a sizeable swath of the continent experienced Mississippianization and came to share similar architecture, pottery, subsistence strategies, sociopolitical organization, iconography, and religion. Together, these essays provide the most comprehensive examination of early Mississippian culture in over thirty years.
