The Chaco Anasazi

sociopolitical evolution in the prehistoric Southwest

Edición de la obra The Chaco Anasazi

In the tenth century AD, a remarkable cultural development took place in the harsh and forbidding San Juan Basin of northwestern New Mexico. From small-scale, simply organized, prehistoric Pueblo societies, a complex and socially differentiated political system emerged which has become known as the Chaco Phenomenon. The origins, evolution, and decline of this system have long been the subject of intense archaeological debate. In her book, The Chaco Anusazi: Sociopolitical evolution in the prehistoric Southwest, Lynne Sebastian examines the transition of the Chaco system from an acephalous society, in which leadership was situational and most decision making carried out within kinship structures, to a hierarchically organized political structure with institutional roles of leadership. She argues that harsh environmental factors did not provide the catalyst for such a transition, as has previously been thought. Rather the increasing political complexity was a consequence of improved rainfall in the region which permitted surplus production, thus allowing those farming the best land to capitalize on their material success. By combining information on political evolution with archaeological data and the results of a computer simulation, the author is able to produce a sociopolitically based model of the rise, florescence, and decline of the Chaco Phenomenon.
