Huitzilopochtli, god of war, fire, and the sun; Tlaloc the rain god; Itzli, god of sacrifice and stone knives; and Quetzalcoatl, creator god, were all worshiped by what people?

Huitzilopochtli, Tlaloc, Itzli, and Quetzalcoatl are all deities from the Aztec pantheon, worshiped by the Aztec civilization in central Mexico. The Incas (Peru), Maoris (New Zealand), and Mbuti (Congo) had completely different religious traditions and did not worship these specific gods. Quetzalcoatl the feathered serpent god is particularly iconic in Aztec mythology.
