Who was pope before Gregory XIII?
Pope Gregory XIII
Pope Gregory XIII (Latin: Gregorius XIII; 7 January 1502 – 10 April 1585), born Ugo Boncompagni, was Pope of the Catholic Church from 13 May 1572 to his death in 1585. He is best known for commissioning and being the namesake for the Gregorian calendar, which remains the internationally accepted civil calendar to this day.

Upon the death of Pope Pius V (1566–1572), the conclave chose Cardinal Boncompagni, who assumed the name of Gregory XIII in homage to the great reforming Pope, Gregory I (590–604), surnamed the Great. It was a very brief conclave, lasting less than 24 hours. Many historians have attributed this to the influence and backing of the Spanish King. Cardinal Borromeo and the cardinals wishing reform accepted Boncompagni's candidature and so supported him in the conclave while the Spanish faction also deemed him acceptable due to his success as a nuncio in Spain.
