This volume brings together essays on the nature of political organization of the Moche, a complex pre-Inca society that existed on the north coast of Peru from c. 100 to 800 CE . Since the discovery of the royal tombs of Sipaacute;n in 1987, the Moche have become one of the best-known pre-Hispanic cultures of the Americas and the focus of a number of archaeological projects. But the nature of Moche political organization is still debated. Some scholars view the Moche as a monolithic state, others see a clear distinction between a northern and southern Moche polity, and yet others argue that the most accurate model is one in which each valley contained an independent polity. In a presentation of new data and new perspectives, the authors debate these competing theories. Based on a set of papers presented by sixteen international scholars at the Dumbarton Oaks Pre-Columbian Studies symposium held in Lima, Peru, in 2004, this volume marks an important point in the development of Moche archaeology and will be a landmark work in Pre-Columbian studies.
