The wars carried out by the aztec empire were linked to the

the practice of human sacrifice

Explanation: The Aztec Empire, or the Triple Alliance was an alliance of three Nahua city-states: Mexico-Tenochtitlan, Texcoco and Tlacopan. These three city-states ruled the area in and around the Valley of Mexico from 1428 until the combined forces of the Spanish conquistadores and their native allies defeated them in 1521.

The Aztec Empire was organized with a strong central government headed by the emperor. The priests and warriors came next and they were made up of nobles who enjoyed a high status in Aztec society. The bulk of Aztec armies however, were made up of commoners who are required to serve time in compulsory military service. Serving in the military was also the only way for a commoner to attain higher status in the Aztec Empire.

The sacrifice of war captives was an important part of many of the Aztec religious festivals. Warfare therefore served a dual purpose for the Aztecs. It was the main driving force of the Aztec economy and secondly it was directly tied to the success of their religious practices.
