In a collaborative research project Dr. Thomas Charlton and Dr.                 Deborah Nichols will conduct archaeological research at the Aztec               site of Otumba which is located in the Teotihuacan Valley,                      Mexico.  One season of fieldwork will be followed by a year of                  analysis.  The Otumba city-state includes a large central "city"                area and smaller surrounding "rural" sites.  The investigators                  will conduct a systematic surface survey and sampling of the city               area to collect artifactual samples in order to understand how                  the site developed over time.  They will then repeat the process                at ca. three rural sites to determine the degree of economic                    interaction between them and the center.  They will then conduct                excavations at the center to learn how the city functioned                      economically and how it related to other similar city-states.                   Since the Aztec practiced irrigation agriculture, Drs. Charlton                 and Nichols will excavate the canal system to reconstruct its                   morphology, development and its importance for agricultural                     production.                                                                                                                                                     At the time Columbus discovered the New World, the Aztec had                    established a large, complex and centrally administered empire.                 While historical accounts provide some insight into how this                    empire functioned, archaeologists have argued about the processes               which led to its development.  This research should help to                     answer the question and provide more general insight into how                   complex societies arise.
