Prehistory of Warfare Volume 56 Number 3, May/June 2003
by Steven A. LeBlanc

Humans have been at each others' throats since the dawn of the species.

In the early 1970s, working in the El Morro Valley of west-central New Mexico, I encountered the remains of seven large prehistoric pueblos that had once housed upwards of a thousand people each. Surrounded by two-story-high walls, the villages were perched on steep-sided mesas, suggesting that their inhabitants built them with defense in mind. At the time, the possibility that warfare occurred among the Anasazi was of little interest to me and my colleagues. Rather, we were trying to figure out what the people in these 700-year-old communities farmed and hunted, the impact of climate change, and the nature of their social systems--not the possibility of violent conflict.

One of these pueblos, it turned out, had been burned to the ground; its people had clearly fled for their lives. Pottery and valuables had been left on the floors, and bushels of burned corn still lay in the storerooms. We eventually determined that this site had been abandoned, and that immediately afterward a fortress had been built nearby. Something catastrophic had occurred at this ancient Anasazi settlement, and the survivors had almost immediately, and at great speed, set about to prevent it from happening again.

Thirty years ago, archaeologists were certainly aware that violent, organized conflicts occurred in the prehistoric cultures they studied, but they considered these incidents almost irrelevant to our understanding of past events and people. Today, some of my colleagues are realizing that the evidence I helped uncover in the El Morro Valley is indicative of warfare endemic throughout the entire Southwest, with its attendant massacres, population decline, and area abandonments that forever changed the Anasazi way of life.
