This research explores the relationship between mortuary practice and sociopolitical change among a collection of communities incorporated into the Inca Empire. I conducted this work in the Chincha Valley of central Peru, an area controlled by a complex polity known as the Chincha Kingdom in the Late Intermediate Period, or LIP (AD 1000 – 1400). During the Late Horizon (AD 1400 – 1532), the Chincha Kingdom fell under the rule of the Inca Empire. In this study, I investigated a dense, well-preserved distribution of graves in the middle Chincha Valley. Using methods from archaeology, GIS, and Bayesian statistical modeling, I examined the nature and development of local mortuary practice in the mid-valley from the LIP to the Late Horizon and recorded over 500 well-preserved graves that cluster into 44 mortuary sites. These sites vary in layout and have two distinct grave types that differ in architecture and use: above-ground and subterranean graves (chullpas) and subterranean cists. Radiocarbon data indicate continuity, change, and innovation in tomb use and treatment of the dead through time. I argue that these diachronic mortuary patterns were products of negotiations among indigenous groups and the Inca. Mid-valley peoples manipulated the remains of their dead to produce new deceased persons before and during their incorporation into the Inca Empire. They dynamically reconfigured the ways relationships among the living and the deceased were performed, thereby transforming their sociopolitical landscape in the face of imperial conquest. This study provides support for a model of mortuary practice as an interface through which interactions between complex societies and expansionist empires occurred.
