The Aztec Civilization
By absorption of other cultural elements and by conquest the Aztec achieved a composite civilization, based on the heritage of Toltec and Mixteca-Puebla. They attained a high degree of development in engineering, architecture, art, mathematics, and astronomy. The Aztec calendar utilized a 260-day year and a 52-year time cycle. Aztec skill in engineering was evident in the fortifications of their island capital. The Aztec further developed sculpture, weaving, metalwork, ornamentation, music, and picture writing for historical records. Agriculture was well advanced and trade flourished.
The political and social organization was based on three castes—nobility, priesthood, and military and merchants. The priesthood was a powerful political as well as religious force. Aztec government was relatively centralized, although many conquered chiefs retained political autonomy; they paid tribute and kept commerce open to the Aztec. The Aztec had a large and efficient army. Prisoners of war were used for human sacrifice to satisfy the many gods of the Aztec pantheon, notably Huitzilopochtli, the chief god, who was god of war.
Spanish Conquest
When the Spaniards, under Hernán Cortés, arrived in 1519, the Aztec civilization was at its height. However, many subject Indian groups, rebellious against Aztec rule, were only too willing to join the Spanish. Initially, the invaders were aided by the fact that the Aztec believed them to be descendants of the god Quetzalcoatl. Montezuma, the last of the independent Aztec rulers, received Cortés, who made him prisoner and attempted to rule through him. The Aztec revolted, Montezuma was killed, and Tenochtitlán was razed (1521). Cuauhtémoc, last of the emperors, was murdered (1525), and the Spanish proceeded to subjugate Mexico.
