Toltec is a term that refers to the ancient Mesoamerican civilization that flourished around 900 AD. The Toltec people were known for their expertise in architecture, art, and religion. However, there are several other synonyms that can be used instead of the word Toltec. One of the most common synonyms is the Nahua people, who were the dominant ethnic group in pre-Columbian Mexico. Another synonym is the Aztec civilization, which succeeded the Toltecs in the 14th century. The Mixtec people, who lived in the northern region of what is now Oaxaca, are also often referred to as Toltecs. Lastly, the Teotihuacan civilization, which predated the Toltecs, is also sometimes used as a synonym for the Toltec people.
