Special Section Introduction: Introducing Zacapu archaeology and the Uacusecha project

Abstract According to Purepecha oral tradition, the ancestors of the Uacusecha dynasty that ruled Michoacan at the beginning of the sixteenth century began their epic in the Zacapu region. The importance of this region also lies in the research carried out since the early 1980s that led to the elaboration of a regional sequence outlining the trajectory of pre-Hispanic societies centuries before the emergence of the Tarascan state. New research carried out on the area since 2009 has clarified this reference framework and opened new perspectives. The research focused on the Malpaís volcanic flows and its immediate surroundings. It addressed the transformations experienced by pre-Hispanic societies between a.d. 500 and a.d. 1580, and their interactions with the volcanic environment with unprecedented analytical detail. The joint contributions of remote sensing, archaeological fieldwork, dating, and geological study participate in renewing a diachronic approach of this unique landscape of northern Michoacan.
