In a collaborative research project Dr. Deborah Nichols and                     Dr. Thomas Charlton 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. Nichols and Charlton 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.
