The emergence of agrarian village life in the Middle Ohio Valley has traditionally been viewed as an isolated, autochthonous development. Fort Ancient (AD 1000-1650) societies are seen as direct descendants of preceding Late Woodland (AD 500-1000) groups. The processes presumed to underlie this transition are gradual aggregation and a growing reliance on maize over time. This project examines village development in detail at Turpin (33HA19), a well-known transitional site in the Little Miami Valley of southwestern Ohio. Relying on the tenets of macroevolutionary theory, I develop a multiscalar framework with four scales of analysis focused on better understanding village development. First, I thoroughly examine one early Fort Ancient site, Turpin, with a focus on community structure, household architecture, chronology, and material culture. Second, I place these finding in the context of contemporary communities in the Middle Ohio Valley, comparing sites based on community structure, architectural style, and ceramic characteristics. Third, I expand scope of analysis by adding contemporary early Mississippian sites in the Lower Ohio Valley and eastern Tennessee, providing a comparative framework for understanding the importance of interregional contact in cultural change. Finally, considering cultural transitions during the period between AD 1000 and AD 1400 occurred in the contexts of the Medieval Climate Anomaly, I use prehistoric drought data to examine shifting climatic conditions in the Midcontinent. These conditions reflect potential push and pull factors influencing the movement of people throughout this region. The findings of this multiscalar project provide evidence that the early Fort Ancient period in the Lower Miami Valleys was catalyzed by an influx of Mississippian migrants. Excavations at Turpin have produced evidence of two early Fort Ancient communities. One house in each community was excavated. House 1 is a Mississippian-style wall trench structure first constructed between cal. AD 1040 and cal. AD 1188, and then renovated between cal. AD 1162 and cal. AD 1250. The basin of this structure was filled with refuse, including Mississippian-like shell tempered vessels with plain surfaces. House 2 is another Mississippian-style wall trench structure built between cal. AD 1206 and cal. AD 1270. This house basin was filled with more classic Fort Ancient ceramics after its occupation ended. Comparing early Fort Ancient sites in the Lower Miami Valleys with contemporary Fort Ancient and Mississippian sites suggests that sites like Turpin, Guard, and State Line were occupied by Mississippian people. These three sites all demonstrate notable Mississippian characteristics, including shell tempered ceramics, circular villages, wall trench houses, and non-local individuals. The movement of Mississippians into the Middle Ohio Valley occurred at a time in which Mississippian polities to the west experienced significant multi-decadal droughts. During this time, the Middle Ohio Valley remained relatively wet. These conditions provided important push (drought) and pull (wet conditions) factors for maize agriculturalists. I argue that mounting evidence from Turpin and other early Fort Ancient sites, many of which stand in stark contrast to preceding Late Woodland settlements, reflect the remains of Mississippian communities, the founders of which emigrated from Mississippian centers like Angel, Kincaid, and Cahokia.
