When used as anethnonym, Matlatzinca refers to the people of Matlatzinco.Matlatzinco was the Aztec (Nahuatl) term for the Toluca Valley. The political capital of the valley was also referred to as “Matlatzinco”; this was a large city whose ruins are today known as the archaeological site ofCalixtlahuaca. In Prehispanic times the Toluca Valley was the home to speakers of at least four languages:Otomi,Matlatzinca,Mazahua, andNahuatl. Thus speakers of any of these languages could be called “Matlatzinca” if they resided in the Toluca Valley. When the Aztec native historical sources or the Spanish chroniclers refer to “the Matlatzinca” it is often not clear where they mean speakers of the Matlatzinca language, the peoples of the Toluca Valley, or even the inhabitants of Calixtlahuaca.
The Matlatzinca language is part of theOto-Pamean subgroup of theOto-Manguean language family, which also includesOtomi,Mazahua,Pame andChichimeca Jonaz. Linguistically the term “Matlatzinca” refers to speakers of the Matlatzinca language. In ancient, historical and modern times, the Matlatzinca language was spoken in the Toluca Valley of central Mexico, west of the Valley of Mexico. The Matlatzinca language has two subgroups or dialects that are mutually unintelligible: one calledOcuiltec or Tlahuica and Matlatzinca proper. While originally one language they are now so removed that they are often considered separate languages.
