In Mesoamerican cultures, the god of war and sun, frequently depicted as a hummingbird, is Huitzilopochtli. He is a central deity in the Aztec pantheon, often associated with the sun and warfare. Huitzilopochtli is believed to demand rituals of human sacrifice to sustain his power and ensure the sun rises each day. His mythology reflects the cultural importance of battle and the reverence for solar energy in ancient Mesoamerica, symbolizing both life and destruction.
