Acamapichtli becomes the first Aztec tlatoani

1372

The Mexica of Tenochtitlan elected their first dynastic ruler, a prince of Culhua-Toltec lineage whose coronation gave the young city-state the genealogical prestige it craved. Under Acamapichtli and his successors, the Aztecs would transform from tribute-paying vassals of Azcapotzalco into the dominant power of the Valley of Mexico, their island capital growing with each generation.
