The Aztecs worshiped many gods. When they took over a new tribe or culture they often adopted the new tribe's gods into the Aztec religion.
The Sun
One of the most important aspects of Aztec religion was the sun. The Aztecs called themselves the "People of the Sun". They felt that in order for the sun to rise each day the Aztecs needed to perform rituals and sacrifices to give the sun strength.
Main Gods
Despite worshiping many gods, there were certain gods that the Aztecs considered more important and powerful than the others. The most important god to the Aztecs was Huitzilopochtli. Here are some of the most important gods to the Aztecs.
The god Huitzilopochtli by Unknown
Huitzilopochtli - The most fearsome and powerful of the Aztec gods, Huitzilopochtli was the god of war, the sun, and sacrifice. He was also the patron god of the Aztec capital city of Tenochtitlan. The Great Temple in the center of the city was built in honor of Huitzilopochtli and Tlaloc. His name is thought to mean "left-handed hummingbird". He was often drawn with feathers and holding a scepter made from a snake.
Tlaloc - Tlaloc was the god of rain and water. While Tlaloc helped the Aztecs much of the time by sending rain and causing plants to grow, he also could get angry and send thunder storms and hail. Tlaloc was worshiped at the Great Temple in the city of Tenochtitlan and also at the top of a tall mountain named Mount Tlaloc. He was often drawn with fangs and big goggle-like eyes.
Quetzalcoatl - Quetzalcoatl was the god of life and wind. His name means "feathered serpent" and he was usually drawn as a serpent which could fly, very much like a dragon. When Cortez first arrived at the Aztecs, many thought that he was the god Quetzalcoatl in human flesh.
Tezcatlipoca - Tezcatlipoca was a powerful god associated with many things including magic, the night, and the earth. He was a rival god to Quetzalcoatl. According to Aztec mythology, he was the first god to create the sun and the earth, but was struck down by Quetzalcoatl and turned into a jaguar. There was a large temple built to him in the city of Tenochtitlan just south of the Great Temple. His name meant "smoking mirror".
Chicomecoatl - Chicomecoatl was the Aztec goddess of agriculture, nourishment, and corn. She was often drawn as a young girl carrying flowers or a woman using the sun as a shield. Her name meant "seven snakes".
