The Toltec culture () was a pre-Columbian Mesoamerican culture that ruled a state centered in Tula, Hidalgo, Mexico, during the Epiclassic and the early Post-Classic period of Mesoamerican chronology, reaching prominence from 950 to 1150 CE. The later Aztec culture considered the Toltec to be 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 Tōltēkatl (singular) or Tōltēkah (plural) came to take on the meaning "artisan". The Aztec oral and pictographic tradition also described the history of the Toltec Empire, giving lists of rulers and their exploits. Modern scholars debate whether the Aztec narratives of Toltec history should be given credence as descriptions of actual historical events. While all scholars acknowledge that there is a large mythological part of the narrative, some maintain that, by using a critical comparative method, some level of historicity can be salvaged from the sources. Others maintain that continued analysis of the narratives as sources of factual history is futile and hinders access to learning about the culture of Tula de Allende. Other controversies relating to the Toltec include the question of how best to understand the reasons behind the perceived similarities in architecture and iconography between the archaeological site of Tula and the Maya site of Chichén Itzá. Researchers are yet to reach a consensus in regards to the degree or direction of influence between these two sites. Origins of society at Tula While the exact origins of the culture are unclear, it likely developed from a mixture of the Nonoalca people from the southern Gulf Coast and a group of sedentary Chichimeca from northern Mesoamerica. The former of these is believed to have composed the majority of the new culture and were influenced by the Mayan culture centered in Teotihuacan. During Teotihuacan's apogee in the Early Classic period, these people were tightly integrated into the political and economic systems of the state and formed multiple large settlements in the Tula region, most notably Villagran and Chingu. Beginning around 650 CE, the majority of these settlements were abandoned as a result of Teotihuacan's decline. The Coyotlatelco rose as the dominant culture in the region. It is with the Coyotlatelco that Tula, as it relates to the Toltec, was founded along with a number of hilltop communities. Tula Chico, as the settlement is referred to during this phase,
