What were the Aztec religious beliefs that affected how they reacted to the Spanish?

The Aztecs believed in a complex system of polytheistic deities, with rituals like human sacrifice to appease the gods. When the Spanish arrived and attempted to convert them to Christianity, it challenged their deeply ingrained religious beliefs and led to resistance and conflict. The Spaniards' destruction of Aztec temples and suppression of their religious practices further fueled the resistance against the Spanish conquest.
