Mexico is a multicultural society. Besides its large majority of Spanish-speakers, it has approximately five million Indians who speak more than 50 Languages. As a resulta of the economic, social, and political changes of the 1910 Revolution, national interest was taken in the linguistic unification of the country. Two main theories were proposed to accomplish the task: (1) forced assimilation into Spanish through education conducted solely in that language and (2) a bilingual system in which indigenous populations were instructed in their own languages, with the subsequent teaching of Spanish. Education policies adhered mostly to the first theory, with bilingual programs being only intermiteently and unsuccessfully attempted.
