Imperial History & Territorial Expansion

Formed in 1428 through an alliance between the Mexica of Tenochtitlan, the Acolhua of Texcoco, and the Tepanec of Tlacopan, the Aztec Empire dominated central Mexico from the Gulf Coast to the Pacific. Their capital, Tenochtitlan, built on an island in Lake Texcoco, was an engineering marvel with raised causeways, stone aqueducts, and floating chinampa agricultural fields. Under Ahuitzotl and Moctezuma II, imperial tribute flowed into the Templo Mayor until the arrival of the Spanish conquistadors in 1519.
