Каэтан
Vitoria was born in Burgos or Vitoria-Gasteiz and was raised in Burgos, the son of Pedro de Vitoria, of Alava, and Catalina de Compludo, both of noble families. As per modern scholarship, he had Jewish ancestry on his maternal side (the Compludos), being related to famous converts like Paul of Burgos and Alfonso de Cartagena. He became a Dominican in 1504, and was educated at the College Saint-Jacques in Paris, where he was influenced by the work of Desiderius Erasmus. He went on to teach theology from 1516 (under the influences of Pierre Crockaert and Thomas Cajetan). In 1522 he returned to Spain to teach theology at the college of Saint Gregory at Valladolid, where many young Dominicans were being trained for missionary work in the New World. In 1524, he was elected to the Chair of theology at the University of Salamanca, where he was instrumental in promoting Thomism (the philosophy and theology of St. Thomas Aquinas). Francisco de Vitoria died on 12 August 1546 in Salamanca.
