In Aztec culture, the god associated with creation and war is Huitzilopochtli. He was seen as a powerful deity, embodying the duality of life and death through his roles in warfare and agriculture. As the protector of the Aztec people, he demanded human sacrifices to ensure the sun's rise and the continuation of life. Huitzilopochtli's significance in mythology illustrates the importance of both creation and destruction in the natural order, as well as the cultural values surrounding sacrifice and devotion in Aztec society.
