The Toltec Civilization was an ancient Mesoamerican culture that thrived between the 10th and 12th centuries in what is now central Mexico. Known for their impressive architectural achievements, the Toltecs built the city of Tula, which featured large stone sculptures and pyramids. They were skilled artisans and traders, influencing later cultures, including the Aztecs. The Toltecs practiced a polytheistic religion, worshipping various gods, including Quetzalcoatl, the feathered serpent deity. Their society was organized into a hierarchical structure, with a ruling elite and a warrior class. The decline of the Toltec Civilization around the 12th century led to the rise of other Mesoamerican cultures.
