After Monte Albn reveals the richness and interregional relevance of Postclassic transformations in the area now known as Oaxaca which lies between Central Mexico and the Maya area and as contributors to this volume demonstrate achieved cultural centrality in panMesoamerican networks. Large nucleated states throughout Oaxaca collapsed after 700 C.E. including the great Zapotec state centered in the Valley of Oaxaca Monte Albn. Elite culture changed in fundamental ways as small citystates proliferated in Oaxaca each with a new ruling dynasty required to devise novel strategies of legitimization. The vast majority of the population though sustained continuity in lifestyle religion and cosmology. Contributors synthesize these regional transformations and continuities in the lower Rio Verde Valley the Valley of Oaxaca and the Mixteca Alta. They provide data from material culture architecture codices ethnohistoric documents and ceramics including a revised ceramic chronology from the Late Classic to the end of the Postclassic that will be crucial to future investigations.
