St. Pius V

In an incredible pontificate of 6 years, St. Pius V vigorously promulgated the decrees of the Council of Trent (1545-1563); issued the Roman Missal, the revised Breviary, and the Catechism of the Council of Trent; excommunicated Elizabeth I of England; established the Index of Forbidden Books; chose 314 bishops; wrote hundreds of bulls; and defeated the Turks at Lepanto in 1571, terminating their dominance of the Mediterranean Sea-all remarkably told in a short, readable biography.
