Original sentence: After the fall of Teotihuacan the Nahua peoples began to arrive in central Mexico displacing Oto-Manguean peoples and rapidly becoming the dominant group in the area.David Wright Carr argues that Proto-Otomi was probably one of the languages spoken in the greatest mesoamerican ceremonial center of the classical period, Teotihuacan.Founded in the twelth century the Otomi citystate of Xaltocan held a dominant position in the basin of Mexico, extending its power northwards dominating the valley of Mezquital in Hidalgo and even reaching as far as the current state of San Luís Potosí.Other important Otomi citystates of the post-classic period were Xilotepec in Northwestern Mexico state.The main argument for this hypothesis being that most of central Mexico is known to have been inhabited by speakers of the Oto-Pamean languages before the arrival of Nahuatl speakers
