Acamapichtli

First tlatoani of Tenochtitlan and founder of the Mexica royal line. The Mexica had been refugees and mercenaries on the swampy edge of the Lake Texcoco basin; Acamapichtli's election as ruler — confirmed by the more powerful Tepanecs of Azcapotzalco — gave them their first dynastic continuity. Every later Mexica ruler descended from him.
