The Toltec Empire appeared in the Central Mexico area in the 10th century AD, when they established their central city of Tula. It is believed that the Toltecs were refugees from the northern Teotihuacán culture and migrated after its fall in 700 AD.
Little is known directly about the Toltecs because the Aztecs plundered the Tula ruins for building materials for their nearby capital, destroying most of the historical evidence that remained. Much of what we know about the Toltecs comes from legends carried on about them by later cultures.
The Toltec Empire was the first of the extreme militaristic cultures in the region that used their might to dominate their neighbors, a trend associated with the later cultures in the region, especially the Aztecs. Eventually the empire spread across most of Mexico, Guatemala, and as far south as the Yucatan, as they conquered lands previously controlled by the Mayans.
