Archaeological data from the Jequetepeque Valley suggest that Late Moche warfare and religious sacrifice were embedded in a particular cosmological and gendered construction of the world. As a consequence, the pragmatic motives implicated in violent conflict were mediated by structures of practice specific to the Moche. An analysis of the archaeological record points to the existence of this cultural schema, the identification of which better explains the ascendancy of the famed priestess cult based at San José de Moro and the general decentralization of power in the Jequetepeque region. The evidence indicates that political relations in the valley were informed by a religious ideology that structured feasting, warfare, and sacrifice as specifically gendered but complementary domains. The spatial delimitation and sequential unfolding of ritual events were likely deemed essential for both socio-cosmic renewal and legitimate political advancement. This gendering of political and religious practices is reflected archaeologically in the division of centered and rural space and in the differential distribution of architectural forms, parochial feasting arenas, and iconographically charged artifacts. Ultimately, the archaeological record demonstrates that the political machinations of rural communities amplified this gendered sacrificial system within the context of the environmental upheavals of the Late Moche Period.
