of Teotihuacan and Cholula. People migrated away from the Tlaxcala area and eventually the zone became tributary provinces of the two powers. Teotihuacan established a trade corridor through Huamantla to connect it to points east and south, but no major settlements. Sometime after this, between 650 and 900 CE, there began Otomi migration into the Huamantla Valley and other parts of Tlaxcala in various waves. There is also evidence of Olmeca-Xicalanca and Tlaxco influence, with the rise of Cacaxtla. The fall of Teotihuacan allowed for local control of the trade corridor. However, from then until the colonial period, the major cultural force was Otomi. Much of this history is known from the Huamantla Codex, the largest document of its kind and one of the few that document the history of an Otomi people. It is in nine fragments, seven at the National Library of Anthropology and History in Mexico City and two in Germany at the Berlin State Library. The central story of the codex is a battle between newly arrived Otomis against those already established and aligned with Tlaxco at Atlangatepec. Victory went to the newcomers, allowing them passage and settlement near the Malinche Volcano, called the Tecoac dominion. These Tecoac Otomi were still a political force when the Spanish arrived. The document was likely commissioned shortly after the conquest, possibly by the Franciscans as the church and monastery of Huamantla are represented. The last indigenous consolidation of power in Huamantla was the creation of the Tlaxcallan dominion, from which the state gets its name. This was a Chichimeca political union that formed around 1100 CE, pushed out the Olmeca-Xilcalancas and divided the territory into four interdependent dominions. Otomi immigration still continued to the area after this, especially after the fall of Tula in 1168. Huamantla belonged to the dominion of Tecoac, one of the four that made up the Tlaxcallan kingdom. This area was first to have contact with Cortés and his army which made an incursion here in 1519 to be attacked, mostly by Otomi vassals. It was the first time the Spanish used their advanced weaponry and quickly dispersed the native soldiers. Colonial period Tlaxcala's role in the Conquest of Mexico allowed indigenous authorities to maintain a number of privileges with Spanish settlers. In 1528, an indigenous delegation went to Spain and one of their tasks was to solicit permission to found the settlement of Huamantla,
