The Aztecs believed in many gods and goddesses, kind of like superheroes, who they thought had special powers and could control different parts of the world. They thought that to keep these gods happy, they had to offer them gifts and sacrifices, kind of like leaving cookies out for Santa.
The Aztecs believed in a big god called Huitzilopochtli, who was the god of war and the sun. They believed that he needed a lot of sacrifices to keep him happy and to make the sun rise every day, so they made him the most important god in their religion.
They also believed in a goddess called Coatlicue, who was the mother of all the other gods. She was very powerful and had the power to give and take life.
The Aztecs had a lot of different ceremonies and rituals to honor their gods. They would make offerings of food, flowers, and sometimes even human sacrifices. They had priests who were in charge of performing these ceremonies and making sure the gods were happy.
The Aztecs were very dedicated to their religion and believed that it was important to keep their gods happy in order to ensure their own safety and prosperity. However, when the Spanish arrived in the 1500s, they brought with them their own religion, Christianity, and forced the Aztecs to convert. This led to the decline of Aztec religion and culture.
