The Aztec sacrifices
The Aztec sacrificed humans so they can repay the gods for making the universe. They believed that a divine power resided in three parts of the body—the head, the heart, and the liver. The Aztec thought that the gods required a ritual payment in the form of human hearts and blood to remain strong. Human sacrifices were elaborate, dramatic ceremonies designed to magically transform the human victims into living representatives of the gods before they were sacrificed. Most of the sacrifices where prisoners or war slaves. The Aztec also sacrificed women to the god Tlaloc, children.
