Aztec Triple Alliance

1428/1429–1521

The Aztec Empire (Nahuatl Ēxcān Tlahtōlōyān, "Tribunal of Three Places") was the alliance formed after the Tepanec War among Tenochtitlan, Texcoco, and Tlacopan, sealed around 1428–1430. Tribute was divided so that two-fifths each went to Tenochtitlan and Texcoco and one-fifth to Tlacopan, with the three cities pledged to cooperate in future wars and to share conquered lands.

Overview

The Aztec Empire (Nahuatl Ēxcān Tlahtōlōyān, "Tribunal of Three Places") was the alliance formed after the Tepanec War among Tenochtitlan, Texcoco, and Tlacopan, sealed around 1428–1430. Tribute was divided so that two-fifths each went to Tenochtitlan and Texcoco and one-fifth to Tlacopan, with the three cities pledged to cooperate in future wars and to share conquered lands. It was a hegemonic, tribute-extracting military confederation rather than a centralized territorial empire, headed by the huey tlatoani of Tenochtitlan, advised by the cihuacoatl (internal ruler) and a Council of Four from whom future rulers were drawn. The Tenochtitlan line ran: Acamapichtli, Huitzilihuitl, Chimalpopoca, Itzcoatl (alliance founder, r. 1427–1440), Moctezuma I (r. 1440–1469, a great conqueror and reformer), Axayacatl, Tizoc, Ahuitzotl (r. 1486–1502, presiding over the empire's greatest territorial extent), Moctezuma II (r. 1502–1520), Cuitláhuac (d. 1520 of smallpox), and Cuauhtémoc (r. 1520–1521, the last). Texcoco's allied rulers included Nezahualcoyotl and Nezahualpilli; Tlacopan's founder-ruler was Totoquihuaztli.

Decline and legacy

The empire commanded a vast tribute economy in maize, cotton textiles, cacao, feathers, jade, and other precious goods, sustained by long-distance pochteca merchants and the great market at Tlatelolco; currency included cacao beans and cotton cloaks (quachtli). Its state religion centered on the war-and-sun god Huitzilopochtli and demanded large-scale human sacrifice, partly fed by ritualized "flower wars." Hernán Cortés landed in 1519, allied with the coastal Totonacs and the fiercely anti-Aztec Tlaxcalans, and seized Moctezuma II as a hostage. Following the Toxcatl massacre, the Mexica revolted and drove the Spanish out on La Noche Triste (30 June 1520), inflicting heavy casualties as the invaders fled the causeways at night. After a smallpox epidemic devastated the city (killing Cuitláhuac), Cortés returned with Tlaxcalan allies and a fleet of brigantines, and after a brutal siege of roughly 93 days captured Tenochtitlan on 13 August 1521. Cuauhtémoc was taken prisoner and later executed (1525) on Cortés's Honduras expedition. The empire's fall inaugurated the Viceroyalty of New Spain.
