How are the army and religious beliefs linked in the Aztec Empire?

Religion, with several public ceremonies aimed to win their gods' favor, was a key element of the Aztec Empire.

Explanation:

Human sacrifices for the Sun God was one of the most significant rites and required a constant supply of prisoners of war, who were killed as offerings to the gods. This meant that the Aztec military had to constantly find new conquests and apply war practices that allowed them to keep prisoners alive for the sacrifices.
