Diego Guzmán de Haros
After he was ordained as a priest, he became chaplain of the Discalced Franciscans in Madrid. In 1608, he became a royal chaplain in the household of Philip III of Spain. He became a member of the Supreme Council of the Spanish Inquisition in August 1613. He also became a canon in the cathedral chapter of Cathedral of Toledo. The king also named him preceptor for his daughters the infantas Maria Anna of Spain.
He was named Patriarch of the West Indies on March 14, 1616 and Titular Archbishop of Tyre on April 18, 1616. He was subsequently consecrated as a bishop. On June 30, 1620, Pope Paul V named him Commissary Apostolic of the Bull of the Crusade he issued that year. He was appointed Archbishop of Seville on September 15, 1625.
Pope Urban VIII created him a cardinal in pectore in the consistory held on November 19, 1629. His appointment was published in the consistory of July 15, 1630. In early 1631, he traveled to the Kingdom of Hungary to accompany his former pupil Maria Anna of Spain to her wedding with Ferdinand III, Holy Roman Emperor. On his way home, he was to travel to Rome to receive the galero from the pope, but he died before that could happen, in Ancona, on January 21, 1631. He was initially buried in the Jesuit church in Ancona, and his remains were later returned to Madrid.
