The Aztec society revolved around keeping the gods happy. They worshipped several gods and goddesses, believing that different gods were in charge of different parts of nature, as well as events like sacrifice and war.
Huitzilopochtli was the most important Aztec god, the sun god. According to legend, he led the people from Aztlan to central Mexico where they settled. He was also the god of war and god of human sacrifice. Sacrifices were made to him to keep the world from falling into a never-ending night.
