Later years of expansion
By the reign of Ahuitzotl, the Mexica were the largest and most powerful faction in the Aztec Triple Alliance. Building on the prestige the Mexica had acquired over the course of the conquests, Ahuitzotl began to use the title "huehuetlatoani" ("Eldest Speaker") to distinguish himself from the rulers of Texcoco and Tlacopan. The alliance still technically ran the empire. But the Mexica Emperor now assumed nominal if not actual seniority.
