When the Aztec asked his god for a sign what happened?

When the Aztecs sought a sign from their god Huitzilopochtli, they received a vision of an eagle perched on a cactus, devouring a serpent. This imagery became a powerful symbol for the Aztec people and indicated the location where they should establish their capital, Tenochtitlán. The vision was interpreted as divine guidance, leading them to settle in the Valley of Mexico where they built a great civilization.
