ナワ族
One of the early complex cultures of Mesoamerica, the Otomi were likely the original inhabitants of the central Mexican highlands before the arrival of Nahuatl speakers around ca. 1000 AD, but were gradually replaced and marginalized by Nahua peoples. In the colonial period Otomi speakers helped the Spanish conquistadors as mercenaries and allies, which allowed them to extend into territories that had previously been inhabited by semi-nomadic Chichimecs, for example Querétaro and Guanajuato.
