Recent investigations of Morton Village, a Mississippian and Oneota community formed following Oneota migration into the central Illinois River valley around AD 1300, focus on evaluating the social context for the remarkable violence evidenced at the adjacent Norris Farms 36 cemetery. Here, we use the concepts of thirdspace and hybridity to examine three areas of village life: creation of the physical structure of the village, ritual, and foodways. Within these three areas, we identify transformations of Mississippian and Oneota practices that support the interpretation that villagers were engaged in the formation of a coalescent community.
