About Culhuacan
Fabled Toltec-Colhua capital and Early Postclassic city-state (c.600–1400 CE) on Lake Xochimilco eastern shore beneath Cerro de la Estrella, with 8 pyramid platforms, ballcourt, and urban terraces 100 ha, center of Colhua genealogy coveted by Mexica for legitimacy — Mexica rulers married Culhuacan daughters to claim Toltec blood. Excavated by INAH and by Parsons, Blanton; produced Coyotlatelco, Mazapan and Aztec I-IV ceramics, obsidian, chinampa canals. Overlain by colonial San Juan Evangelista monastery atop pyramid.
Why it mattersGenealogical heart of Postclassic legitimacy ideology; links Toltec fall to Aztec ethnogenesis via intermarriage claims.
