The Aztec civilization of Central Mexico consisted of several communities with distinct cultures and languages. The Nahuatl-speaking tribes were the most popular and celebrated rituals based on their own version of myths and stories. While the Mesoamerican cultures shared many stories, rituals, and myths with the Aztecs, they were recognized as a separate community. The Aztecs were believed to come from the regions around Lake Texcoco and the Anahuac Valley. These regions collectively form the modern Mexico City we know today.
