Abstract
Recent archaeological and epigraphic research suggests the existence of what could be Mesoamerica's first conquest state, centered at Monte Albán, the major Late Formative period Zapotec site in the Valley of Oaxaca. This paper explores the idea of an early Zapotec empire by examining evidence from one of Monte Albán's outlying regions, the southern Isthmus of Tehuantepec. The study is framed in terms of three hypothetical models of political and economic interaction, any one or combination of which could conceivably account for ancient Zapotec relationships with the southern Isthmus and its other hinterland regions.
