Toltec The Toltec culture is an archaeological Mesoamerican culture that dominated a state centered in Tula, Hidalgo, Mexico in the early post-classic period of Mesoamerican chronology (ca. 900–1168 CE). The later Aztec culture saw the Toltecs as their intellectual and cultural predecessors and described Toltec culture emanating from "Tōllān" ] (Nahuatl for Tula) as the epitome of civilization; in the Nahuatl language the word "Tōltēcatl" ] (singular) or "Tōltēcah" ] (plural) came to take on the meaning "artisan".
