From 1556 to 1560 he was counselor to the Inquisition in Venice, but his ardor caused trouble and he was recalled. In 1565 he went to Spain to look into the alleged heresy of the archbishop of Toledo and so seriously fell out with his companion, Cardinal Buoncompagni (later Gregory XIII), that they became enemies for life. He was created cardinal (1570) by St. Pius V. As pope, Sixtus V set about bringing order to the Papal States, which were at the mercy of brigands, and his methods, if violent, were successful. He spent a vast amount of money on the city of Rome, rebuilding countless churches, beautifying streets, and erecting new buildings and monuments. Sixtus left a tremendous surplus in the treasury by collecting new taxes, selling offices, and making loans. He reorganized the pontifical administration and the sacred college, which he set at the number of 70. He gave his sanction to Philip II of Spain's attempt to invade and restore Catholicism to England, an endeavor that ended in the defeat of the Spanish Armada. Sixtus V is one of the great figures of the Counter Reformation. He was succeeded by Urban VII.

Sixtus V

orig. Felice Peretti

(born Dec. 13, 1520, Grottammare, Ancona, Papal States—died Aug. 27, 1590, Rome) Pope (1585–90). A dedicated Franciscan and two-time inquisitor general of Venice, Sixtus was elected pope at a time when the Papal States were in chaos. He suppressed brigandage and restored order using harsh measures that won him many enemies. He raised vast sums through loans, taxes, and the sale of offices and carried out an extensive building program in Rome. He defined the Sacred College of Cardinals (1586), limiting the number of cardinals to 70, and his reforms of the Roman Curia (1588) lasted until the Second Vatican Council. An energetic supporter of the Council of Trent, whose decisions he implemented, Sixtus is recognized as one of the founders of the Counter-Reformation. His foreign policy was aimed at combatting Protestantism; he excommunicated the Protestant Henry of Navarre (later Henry IV of France) and promised subsidies in return for a Spanish invasion of England. He supported other Catholic rulers in Europe and moderated his position toward Henry when it became apparent the future king would convert to Catholicism.
