RESUMO
Increasing violence and inter-group conflict in the American Southwest is prevalent into the 13th and 14th centuries AD. In the northern Mogollon region during this time period, the site of Grasshopper Pueblo experienced a shift in social organization as population movements occurred in response to regional stressors. The skeletal remains of 187 adult individuals from the site are analyzed for nonlethal and lethal trauma, musculoskeletal stress markers, and pathology as indicators of changing social dynamics. Nonlethal, healed trauma is present in all adult age groups and both sexes. Approximately one-third (n=63) of the population has healed cranial depression fractures. Females and males are fairly equal in the proportion of cranial injuries incurred; however more females are injured overall when post-cranial injuries are added. Musculoskeletal stress markers do not differ substantially among age groups or between sexes. Heavy musculature development is also similar for groups with and without cranial depression fractures. The results of this study suggest that interpersonal violence was ubiquitous within the pueblo and may have escalated as the community grew in size. Immigrants from other parts of the Southwest may have sought refuge at Grasshopper only to find that the community was experiencing its own social stress.
