To determine the impact the fall of the Wari Empire had on domestic violence in coastal, peripheral, pre-Columbian Peruvian communities, human skeletal remains from 32 individuals from Ancon, Peru, were examined for cranial trauma. The lack of any form of contextual domestic abuse injuries found in the Middle Horizon, the time of the Wari, and the Late Intermediate Period, following imperial collapse, illustrates how Ancon's proximity to the Pacific Ocean's ample marine resources exempted its occupants from the stress felt by resourcedeprived highland populations of the same time period
