Bernardino de Sahagún (; c. 1499 – 5 February 1590) was a Franciscan friar, missionary priest and pioneering ethnographer who participated in the Catholic evangelization of colonial New Spain (now Mexico). Born in Sahagún, Spain, in 1499, he journeyed to New Spain in 1529. He learned Nahuatl and spent more than 50 years in the study of Aztec beliefs, culture and history. Though he was primarily devoted to his missionary task, his extraordinary work documenting indigenous worldview and culture has earned him the title as “the first anthropologist." He also contributed to the description of the Aztec language Nahuatl. He translated the Psalms, the Gospels, and a catechism into Nahuatl.
