According to Gabriel Kruell of UNAM's Instituto de Investigaciones Históricas, he spent his career at the [National Autonomous University of Mexico](https://www.edgepedia.org/national-autonomous-university-of-mexico) (UNAM), and he was elected to the United States National Academy of Sciences in 1995,[1](https://www.academiamh.com.mx/miembros/miguel-leon-portilla-2/) described by UNAM's gazette as the most decorated academic in Mexico.[2](https://www.gaceta.unam.mx/muere-miguel-leon-portilla/) His output comprised about 500 research articles and nearly fifty books, 31 of them translated into languages other than Spanish.[2](https://www.gaceta.unam.mx/muere-miguel-leon-portilla/)\n\n| | |\n|---|---|\n| **Born / died** | 22 February 1926, Mexico City – 1 October 2019, Mexico City, aged 93[3](https://www.juntadegobierno.unam.mx/integrante/miguel-leon-portilla) • [4](https://www.cambridge.org/core/journals/americas/article/in-memoriam-miguel-leonportilla-19262019/CC1A187713F26391EE862B933A68C337) |\n| **Field** | Nahuatl studies, pre-Hispanic history and thought, at UNAM's Instituto de Investigaciones Históricas (1957–2019)[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) |\n| **Training** | BA Loyola University Los Angeles (1948);

according to his essay \"En los cincuenta años de este libro\", he earned a [Bachelor of Arts](https://www.edgepedia.org/bachelor-of-arts) in 1948 and a master's degree summa cum laude in 1951 with a thesis on Bergson's *Las dos fuentes de la moral y la religión*.[6](http://hdl.handle.net/20.500.12525/137) • [1](https://www.academiamh.com.mx/miembros/miguel-leon-portilla-2/) In mid-1952 he approached the Nahuatl scholar Ángel María Garibay K., who made learning Nahuatl a condition for studying Nahuatl thought; Garibay tutored him twice a week and remained his mentor until Garibay's death in July 1967.[6](http://hdl.handle.net/20.500.12525/137) • [8](https://scholarworks.iu.edu/iupjournals/index.php/jwp/article/download/629/84/2002)\n\nHe completed the doctoral thesis *Filosofía náhuatl estudiada en sus fuentes* around mid-1956, defended it before a committee presided by Francisco Larroyo, and received the grade summa cum laude.[6](http://hdl.handle.net/20.500.12525/137) In 1957 he joined UNAM's Instituto de Historia (later the Instituto de Investigaciones Históricas) as a researcher and, with Garibay, founded the Seminario de Cultura Náhuatl; El Colegio Nacional credits him with founding the journal *Estudios de Cultura Náhuatl*, which appeared in 1959,[9](https://colnal.mx/integrantes/miguel-leon-portilla/) while *Ancient Mesoamerica* records it as founded by Ángel María Garibay in 1959 and continued by León-Portilla.[7](https://www.cambridge.org/core/journals/ancient-mesoamerica/article/miguel-leonportilla-and-archaeology/F096722EC343E74152D0E213C118319F) \n\nHis later appointments were: professor in UNAM's Facultad de Filosofía y Letras from 1957; director of the Instituto Indigenista Interamericano from 1960 to 1966; director of the Instituto de Investigaciones Históricas, dated 1963–1975 by El Colegio Nacional and 1966–1976 by the Academia Mexicana de la Historia; member of UNAM's governing Junta de Gobierno from 1976 to 1986; and emeritus researcher from 1988.[1](https://www.academiamh.com.mx/miembros/miguel-leon-portilla-2/) • [9](https://colnal.mx/integrantes/miguel-leon-portilla/) As director he created the institute's Anthropology Section and, with rector Guillermo Soberón's support, helped establish UNAM's Instituto de Investigaciones Antropológicas in 1973.[7](https://www.cambridge.org/core/journals/ancient-mesoamerica/article/miguel-leonportilla-and-archaeology/F096722EC343E74152D0E213C118319F) \n\n## Representative work\n\n**La filosofía náhuatl (1956).** The book, built from primary sources including the *Cantares mexicanos*, passages recorded by fray [Bernardino de Sahagún](https://www.edgepedia.org/bernardino-de-sahagun), and pre-Hispanic and colonial manuscripts such as the Borgia and Fejérváry-Mayer codices, reconstructed what the *tlamatinime*, the Nahuatl sages, thought about the origin of the gods, the order of the cosmos, the human condition, art, poetry, knowledge, and death.[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) He identified the *tlamatinime* as wise individuals who reflected on the meaning of existence, highlighting the poet-kings Nezahualcóyotl and [Nezahualpilli](https://www.edgepedia.org/nezahualpilli), and showed that philosophical reflection was not exclusive to Greece or Europe.[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) Nahuatl thought, he argued, was expressed poetically through diphrases: *in tlilli, in tlapalli* (\"the black ink, the red ink\") for wisdom; *in xochitl, in cuicatl* (\"the flower, the song\") for what is good and beautiful; *in ixtli, in yollotl* (\"the face, the heart\").[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) • [8](https://scholarworks.iu.edu/iupjournals/index.php/jwp/article/download/629/84/2002) The book was published in 1956 by the Instituto Indigenista Interamericano, reissued by UNAM's Instituto de Investigaciones Históricas in 1959, and translated into Russian (1961), English as *Aztec Thought and Culture* (University of Oklahoma Press, 1963), German (1970) and French (1985).[6](http://hdl.handle.net/20.500.12525/137) • [1](https://www.academiamh.com.mx/miembros/miguel-leon-portilla-2/)\n\n**Visión de los vencidos (1959).** This anthology of indigenous Nahuatl accounts of the Spanish Conquest, drawn from the *Anales de Tlatelolco*, and Sahagún's Book XII and illustrated by Alberto Beltrán, has been translated into some twenty languages, including English as *Broken Spears: The Aztec Account of the Conquest of Mexico* (1962), and is considered one of the most influential works in Mesoamerican historiography.[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) • [10](https://www.gaceta.unam.mx/miguel-leon-portilla-un-universitario-centenario/) UNAM's gazette called it the most widely circulated book UNAM has published,[2](https://www.gaceta.unam.mx/muere-miguel-leon-portilla/) and by its 2026 centenary coverage it had been reissued 35 times, with recent translations in Chinese and Nahuatl.[11](https://colnal.mx/noticias/recuerdan-a-miguel-leon-portilla-el-historiador-mas-importante-del-siglo-xx-en-la-fiesta-del-libro-y-la-rosa-2026/)\n\nHis other source work included *Trece poetas del mundo azteca* (1967), an anthology of the *tlamatinime* with his translations from the *Cantares mexicanos*, the facsimile edition of that manuscript (1994), and a 1986 edition of the *Colloquios y Doctrina Christiana*, Sahagún's record of the dialogues of the twelve first [Franciscans](https://www.edgepedia.org/franciscans) with indigenous sages, with his paleography and direct translation of the Nahuatl text.[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) • [1](https://www.academiamh.com.mx/miembros/miguel-leon-portilla-2/) According to an in memoriam published by the Academy of American Franciscan History, from 2005 he worked with Mexican scholars on a transcription of the Nahuatl text of the [Florentine Codex](https://www.edgepedia.org/florentine-codex) with Spanish translation, and his 1999 biography argued that Sahagún's use of native informants and questionnaires was a point of origin for modern ethnography.[4](https://www.cambridge.org/core/journals/americas/article/in-memoriam-miguel-leonportilla-19262019/CC1A187713F26391EE862B933A68C337) • [12](https://doi.org/10.1215/00141801-8579666) \n\n## Honors and recognition\n\nAccording to the Academia Mexicana de la Lengua, he was elected to that academy in 1961 (admission lecture 1962, chair VII), to El Colegio Nacional in 1971, and to the Academia Mexicana de la Historia in 1972, directing the latter from 1996 to 2004.[13](https://academia.org.mx/academicos-2019/item/miguel-leon-portilla-2) • [9](https://colnal.mx/integrantes/miguel-leon-portilla/) His prizes included the Premio Elías Sourasky (1966), a [Guggenheim Fellowship](https://www.edgepedia.org/guggenheim-fellowship) (1969), the Premio Nacional de Ciencias Sociales, Historia y Filosofía (1981), the Premio Universidad Nacional (1994), the Medalla Belisario Domínguez (1995), the Premio Menéndez Pelayo (2001), the Serra Award of the Americas (1978), and the Gran Cruz de la Orden de Alfonso X el Sabio (1999);[3](https://www.juntadegobierno.unam.mx/integrante/miguel-leon-portilla) • [9](https://colnal.mx/integrantes/miguel-leon-portilla/) • [4](https://www.cambridge.org/core/journals/americas/article/in-memoriam-miguel-leonportilla-19262019/CC1A187713F26391EE862B933A68C337) the US Library of Congress named him a Living Legend in 2014.[8](https://scholarworks.iu.edu/iupjournals/index.php/jwp/article/download/629/84/2002) His election to the United States National Academy of Sciences came in 1995.[1](https://www.academiamh.com.mx/miembros/miguel-leon-portilla-2/)\n\n## Reception and later scholarship\n\nThe 1956 thesis caused a stir: according to an obituary for Dr. Miguel León-Portilla in *The Americas*, philosophers, including the neokantian Francisco Larroyo, objected that native peoples of Mexico were incapable of true philosophy, and Larroyo called the question anachronistic and the thesis's methodology false.[12](https://doi.org/10.1215/00141801-8579666) • [14](https://revistas.um.es/navegamerica/article/download/567131/359801) In his 1964 review of the English edition, H. B. Nicholson credited the book's reliance on native-language texts and called its linguistic analyses often very valuable, but argued that León-Portilla had often overstated his case, questioning whether a truly professional group of full-time thinkers devoted to rational inquiry existed among the Nahuas and doubting that the *tlamatinime* were sharply separated from the priesthood.[15](https://read.dukeupress.edu/hahr/article/44/4/591/159147/Aztec-Thought-and-Culture-A-Study-of-the-Ancient)\n\nFrom the 1980s, Alfredo López Austin and others reformulated the concept of a Nahuatl philosophy centered on exceptional sage-poets into a broader Nahuatl *cosmovisión*, an ideological and cultural framework regulating social life, and criticized León-Portilla's translations as imprecise and shaped by European classical vocabulary, citing examples such as *teyacayani*, which he rendered as \"teólogo\" but which means leader or guide, and *mictlanmatini*, rendered \"físico\" but meaning knower of the region of the dead.[5](https://historicas.unam.mx/sites/default/files/recurso-descarga/miguel-leon-portilla-gabriel-kruell.pdf) • [14](https://revistas.um.es/navegamerica/article/download/567131/359801) According to a study published on Dialnet, in a 1993 appendix to the seventh edition of *La filosofía náhuatl*, León-Portilla acknowledged that the texts from which he had drawn Nahuatl philosophy could hardly be confronted with surviving pre-Hispanic codices, and he shifted the emphasis toward mythical texts.[16](https://dialnet.unirioja.es/descarga/articulo/5301868.pdf) A separate dispute concerns the English title *Broken Spears*: scholars including John Schwaller argue the Nahuatl phrase should read \"broken bones\" (*omitl*) rather than \"broken spears\" (*mitl*), a point-counterpoint published in *The Americas* in 2009.[12](https://doi.org/10.1215/00141801-8579666)\n\n## Centenary and recent standing\n\nIn 2026, the centenary of his birth, INAH and the Secretaría de Cultura held a homage at the Museo Nacional de Culturas Populares, and El Colegio Nacional held another in April 2026, where the historian Javier Garciadiego called him \"the most important historian of the twentieth century\".[17](https://www.inah.gob.mx/images/boletines/2026/120/Boletin_120.pdf) • [11](https://colnal.mx/noticias/recuerdan-a-miguel-leon-portilla-el-historiador-mas-importante-del-siglo-xx-en-la-fiesta-del-libro-y-la-rosa-2026/) El Colegio Nacional, with UNAM, the [Universidad Iberoamericana](https://www.edgepedia.org/universidad-iberoamericana), and the academies of History and Language, published a posthumous book by him, and his collected works have been issued in about 10 volumes.[11](https://colnal.mx/noticias/recuerdan-a-miguel-leon-portilla-el-historiador-mas-importante-del-siglo-xx-en-la-fiesta-del-libro-y-la-rosa-2026/) • [9](https://colnal.mx/integrantes/miguel-leon-portilla/) \n\n## References\n\n1.
