From ca. 1700, the status of Purépecha changed, and throughout the 20th century, the Mexican government pursued a policy of Hispanicization. Speakers of indigenous languages were actively encouraged to abandon their languages in favor of Spanish. However, in accord with international changes in favor of recognizing the linguistic rights of indigenous peoples and promoting multiculturalism in colonial states, the Congress of the Union of Mexico approved the General Law of Linguistic Rights of the Indigenous Peoples in 2003, giving Purépecha and Mexico's other indigenous languages official status as "national languages."
