Returning and reuse: Diachronic perspectives on multi-component cemeteries and mortuary politics at Middle Neolithic and Early Bronze Age Tara, Ireland

•Fine-grained chronologies are needed to understand the roles of mortuary rituals.•Returning and reuse provide a diachronic framework to the development of cemeteries.•The community using Tara changed as it developed into a regional mortuary center.•Bronze Age mortuary politics, not Neolithic ancestors, led to centralization.•The centralization was brief as these social transformations ultimately failed.

Archaeologists studying multi-component cemeteries have argued that the societies who reused cemeteries were motivated by connecting to the past. However, often overlooked are the potential roles of mortuary events and sites as key social and political venues for creating, contesting, and unmaking relationships and identities for the later community independent of a connection to the past. In this paper, I explore the social and political roles that mortuary rituals at the Mound of the Hostages, Tara, Ireland played during the Middle Neolithic (3350–2800 BC) and Early Bronze Age (2300–1700 BC).Tara’s emergence as a regional mortuary center occurred only several hundred years after its initial reuse by Early Bronze Age peoples. Just as importantly, the burial activity that marked Tara as special in the Early Bronze Age was very brief, revealing that the regional centralization at Tara was ultimately unsuccessful. The analysis of cemetery formation at Tara is only possible due to the development of a fine-grained site specific chronology. These results have broad implications for how we understand cemetery formation, the reuse of mortuary monuments, and the dynamics of social complexity in prehistoric societies.
