order to facilitate communication between the Spanish and natives of the colonies. This led to Spanish missionaries teaching Nahuatl to Amerindians living as far south as Honduras and El Salvador. During the 16th and 17th centuries, Classical Nahuatl was used as a literary language, and a large corpus of texts from that period exists today. They include histories, chronicles, poetry, theatrical works, Christian canonical works, ethnographic descriptions, and administrative documents. The Spanish permitted a great deal of autonomy in the local administration of indigenous towns during this period, and in many Nahuatl-speaking towns the language was the de facto administrative language both in writing and speech. A large body of Nahuatl literature was composed during this period, including the Florentine Codex, a twelve-volume compendium of Aztec culture compiled by Franciscan Bernardino de Sahagún; Crónica Mexicayotl, a chronicle of the royal lineage of Tenochtitlan by Fernando Alvarado Tezozómoc; Cantares Mexicanos, a collection of songs in Nahuatl; a Nahuatl-Spanish/Spanish-Nahuatl dictionary compiled by Alonso de Molina; and the Huei tlamahuiçoltica, a description in Nahuatl of the apparition of Our Lady of Guadalupe. Grammars and dictionaries of indigenous languages were composed throughout the colonial period, but their quality was highest in the initial period. The friars found that learning all the indigenous languages was impossible in practice, so they concentrated on Nahuatl. For a time, the linguistic situation in Mesoamerica remained relatively stable, but in 1696, Charles II of Spain issued a decree banning the use of any language other than Spanish throughout the Spanish Empire. In 1770, another decree, calling for the elimination of the indigenous languages, did away with Classical Nahuatl as a literary language. Until Mexican Independence in 1821, the Spanish courts admitted Nahuatl testimony and documentation as evidence in lawsuits, with court translators rendering it in Spanish. Modern period Throughout the modern period the situation of indigenous languages has grown increasingly precarious in Mexico, and the numbers of speakers of virtually all indigenous languages have dwindled. Although the absolute number of Nahuatl speakers has actually risen over the past century, indigenous populations have become increasingly marginalized in Mexican society. In 1895, Nahuatl was spoken by over 5% of the population. By 2000, this proportion had fallen to 1.49%. Given the process of marginalization combined with the trend of migration to urban areas and to the United States, some linguists are warning of impending language death. At present Nahuatl is mostly
