Consequences of conquest? The analysis and interpretation of subadult trauma at Puruchuco-Huaquerones, Peru

This paper examines bioarchaeological evidence of violence and traumatic injury on subadult skeletal remains from two Late Horizon (A.D. 1470–1540) cemeteries within the archaeological zone of Puruchuco-Huaquerones, Peru. Here we present the frequency and types of traumatic lesions on the 242 subadults analyzed. We observed significant increases in the frequency of subadult trauma, particularly among the burials associated with Spanish Conquest. Specifically, we noted a statistically significant increase in the frequency of cranial trauma in a subsample of individuals from one of two cemeteries at the site, 57AS03. These perimortem cranial injuries suggest an intensification of violence and lethality that may have affected the children from this community. We then discuss the biocultural implications of this analysis within the context of Spanish invasion and conquest.

► We examine subadult trauma at the archaeological site of Puruchuco-Huaquerones. ► Two distinct cemetery areas are examined, one including post- contact material. ► The nature and frequency of subadult trauma changes in post-contact materials. ► An increase in frequency and lethal injuries is associated with Spanish conquest.
