Tenochtitlan

1325/1326–1428 as tributary *altepetl*; core of the empire thereafter

Tenochtitlan, the Mexica (Aztec) capital, was founded on an island in Lake Texcoco — traditionally in 1325 — where, per the migration legend, the wandering Mexica saw the promised divine omen of an eagle perched on a nopal cactus (the image enshrined on the modern Mexican flag). The Mexica had arrived as impoverished latecomers and mercenaries, and initially served and paid tribute to the powerful Tepanec city of Azcapotzalco under its king Tezozomoc.

Overview

Tenochtitlan, the Mexica (Aztec) capital, was founded on an island in Lake Texcoco — traditionally in 1325 — where, per the migration legend, the wandering Mexica saw the promised divine omen of an eagle perched on a nopal cactus (the image enshrined on the modern Mexican flag). The Mexica had arrived as impoverished latecomers and mercenaries, and initially served and paid tribute to the powerful Tepanec city of Azcapotzalco under its king Tezozomoc. Lacking legitimate dynastic rank, Mexica leaders petitioned Culhuacan for a royal bride, and her son Acamapichtli became the first tlatoani (traditionally enthroned 1372/1376), founding the imperial dynasty; he replaced houses of cane with stone, built a great temple, and was said to have promulgated the first Aztec laws. He was followed by Huitzilihuitl and Chimalpopoca.

Decline and legacy

The city was an engineering marvel, built on chinampas (highly productive raised agricultural beds reclaimed from the lake), linked to the mainland by causeways with removable bridges, and supplied with fresh water by aqueduct from Chapultepec. When Chimalpopoca died amid the Tepanec succession crisis under Maxtla, the Mexica under Itzcoatl allied with Texcoco and Tlacopan to destroy Azcapotzalco (1428), transforming Tenochtitlan from a tributary town into an imperial capital. At its height it and its twin, Tlatelolco (with its vast market), together may have held 200,000 or more inhabitants, astonishing the Spanish who compared it to Venice. Tenochtitlan fell to Cortés on 13 August 1521 and was systematically razed; Mexico City, with its cathedral built over the ruins of the Templo Mayor, rose in its place.
