Introduction: What Happened after the Fall of Teotihuacan?

Abstract

The fall of Teotihuacan, associated with the internal revolt and the AD 550–570 “Great Fire,” shook Mesoamerica. Demographic displacements and military competition between sites were all characteristics of the subsequent Epiclassic period. This section will review data from my project “The Study of Tunnels and Caves in Teotihuacan (1987–1996),” behind the Pyramid of the Sun. Two of the four tunnels were extensively excavated and, for the first time, provide substantial evidence of subsistence, domestic and craft activities, and a vast array of ritual contexts from Epiclassic and Postclassic groups living at Teotihuacan. Radiocarbon samples from activity areas were analyzed with Bayesian statistics, providing the chronology for the Coyotlatelco occupation between ca. AD 640 and 820; the transition between Coyotlatelco/Mazapa by ca. AD 890–940; the Mazapa occupation between AD 940 and 1230; then a hiatus followed by the Aztec III occupation by ca. AD 1390–1460. Chemical analyses of activity areas in the Varillas Tunnel provided a different perspective for the study of activities. The presence of clear occupational levels and activity areas allowed us to reconstruct the life of post-Teotihuacan groups, with a large quantity and variety of ecofacts, human and faunal burials, and different types of instruments and complete objects.
