Archaeological explanations for incidents of violence range from environmental degradation to conflicts over territorial boundaries to raiding for women and/or food. Research presented here argues that migration corridors may also create situations of conflict leading to outright violence using the case study of the Gallina, an Ancestral Pueblo group living in what is now northern New Mexico from approximately A.D. 1100 – 1300. Prior research in the Gallina region focused on the high degree of violence in the region, with no clear understanding about the origins or nature of that violence. I argue in this chapter that by understanding groups in relation to their neighbors, archaeologists can better understand regional processes like migration and violence. Specifically, GIS and least-cost path analyses suggest that the violence in the region is episodic, but also spatially and temporally patterned in ways that correlate with potential corridors of movement of migrants from the Four Corners, traveling through northern New Mexico, toward the Rio Grande and Rio Chama areas.
