The definition of the regional limits of chiefly influence during the Mississippian period in the southeastern United States remains unresolved. In the Gulf Coastal Plain between the Mississippi and Black Warrior rivers, some studies have explored the role that interpolity interactions played in influencing a polity’s social and political complexity through time. It has been argued that the larger, more complex polities were able to preempt the development of more complex political structures among the smaller polities. Using research at the Pevey (22Lw510) and Lowe-Steen (22Lw511) mound sites on the Pearl River in Lawrence County, Mississippi, this book explores the social and political mechanisms by which these polities may have interacted with each other and the geographic limit to the effects of inter-polity competition. The Pevey site is a nine-mound Mississippian site and Lowe-Steen is a two-mound site located 18 kilometers to the north of Pevey. These sites provide a “missing link" of sorts to explore questions about inter-polity interactions because of their centrality to the study region and their unusual size. By filling a void in the regional dataset, this study allows us to better understand the capacity of the largest polities to negatively effect the political development of their smaller neighbors. | Mississippian Polity and Politics on the Gulf Coastal Plain by Patrick C.
