Decline of Teotihuacan

Timeline

1. 600–650Teotihuacan Valley · MexicoArchaeological evidence shows a significant drop in the city's population in the first half of the 7th century, with some residential areas abandoned and long-distance trade in obsidian and greenstone declining, indicating that Teotihuacan was losing its appeal as a regional distribution center.
2. 650–700Pyramid of the Sun and Pyramid of the Moon area · MexicoMany palaces and temples in the ceremonial center were deliberately burned and dismantled, elite tombs were disturbed, and large-scale public ceremonies ceased, marking the fundamental collapse of the city's political-religious order.
3. 650–700Mexican Highlands · MexicoAfter Teotihuacan's decline, city-states such as Xochicalco and Cacaxtla, and later precursor forces of the Toltecs, expanded across the highlands; Maya lowland polities also adjusted their relations with the northern metropolis, reorganizing Mesoamerica's overall political map.
