Betanzos was born around 1480 in the city of León, Spain. He graduated in civil and ecclesiastical law from the University of Salamanca. He made a pilgrimage to Rome and spent two years as a hermit on the island of
Ponza, near Naples. After returning to Salamanca he joined the Dominicans and was ordained a priest in 1513. Later that year, he traveled to Hispaniola with seven other Dominican friars and worked on the island for more than twelve years as a missionary. In 1516 he, with several other Dominicans, wrote a letter to
Las Casas on the rapid disappearance of the Indians of the Antilles, concerning the numbers of the aboriginal population, and the excesses thought to have been committed by the Spaniards. In 1518 Betanzos and Pedro de Córdoba attempted to establish a mission on the island of Margarita, but extreme hostility of the indigenous people forced the Dominicans to return to Hispaniola. In 1522, Betanzos, then vicar of the Dominican friars in Hispaniola, convinced the cleric Bartolomé de las Casas to enter the Dominican novitiate. In 1526, Betanzos went to Mexico, one of the first Dominicans; and he is considered the founder of the Dominican province of Santiago de México. According to Franciscan fray
Gerónimo de Mendieta, Betanzos did not know any native language and had little to do with Indians, his time being absorbed by administrative duties.
Tomás de Berlanga almost immediately claimed that it belonged to his newly founded province of Santa Cruz with the provincial seat at Santo Domingo. Betanzos went to Spain in 1531 and obtained from the Holy See the independence of his foundation. He also established the Dominican Province of
Guatemala. As Provincial of Mexico in 1535, he organized missions among three Indigenous groups stocks: the
Nahua people, the
Mixtec people, and the
Zapotec people. He returned to Spain in 1549, and died in September of the same year at Valladolid. The Bishopric of Guatemala was tendered to Betanzos, but he declined it. In his classic work on the evangelization of Mexico, French scholar Robert Ricard called Betanzos zealous, "an impetuous character, not well balanced, but not without intelligence" with a passionate temper. A portrait of Betanzos on
amatl (maguey paper) was held in the church of Tlazcantla, Tepetlaostoc (Mexico). ==Views==
