Tlatoani

Tlahtoāni (Classical Nahuatl: tlahtoāni pronounced [t͡ɬaʔtoˈaːniˀ] , "ruler, sovereign"; plural tlahtohqueh [t͡ɬaʔˈtoʔkeʔ]) is a historical title used by the dynastic rulers of āltepēmeh (singular āltepētl, often translated into English as "city-state"), autonomous political entities formed by many pre-Columbian Nahuatl-speaking peoples in the Valley of Mexico during the Postclassic Period. The title of huēyi tlahtoāni ([ˈweːjiˀ t͡ɬaʔtoˈaːniˀ], "great ruler, emperor") was used by the rulers of the Aztec Empire, an alliance between the āltepēmeh of Tenochtitlan, Tetzcoco, and Tlacopan. Each āltepētl had its own tlahtoāni who would concurrently function as its ruler, high priest and commander-in-chief. The tlahtoāni wielded ultimate authority over all land within the āltepētl, overseeing tribute collection, market activities, temple affairs, and the resolution of judicial disputes. Typically a dynastic ruler hailing from the royal lineage, the tlahtoāni served for life. However, in certain instances, a council of nobles, elders, and priests could elect a tlahtoāni from a pool of four candidates.
