In Aztec religion, who was the most important deity?

In Aztec religion, the most important deity was actually the god of War, who is often identified as Huitzilopochtli, the god of the sun and warfare. While the god of Maize, known as Centeotl, held significant importance due to the agricultural society of the Aztecs, deity Centeotl was not regarded as the most central figure in Aztec cosmology and rituals. The Aztecs placed a great emphasis on warfare and sacrifice to appease powerful deities who would ensure victories in battle, favor in agricultural production, and ultimately the continuation of their society.

The god of Water, Tlaloc, and the god of the Underworld, Mictlantecuhtli, were also influential within the pantheon, but neither surpassed the importance attributed to Huitzilopochtli in their religious practices and societal structure. Thus, the correct answer highlights the pivotal role Huitzilopochtli played in the Aztec belief system.
