About

He was an inquisitor and is venerated as a saint of the Catholic Church. He is chiefly notable for his role in the implementation of the Council of Trent, the Counter-Reformation, and the standardization of the Roman Rite within the Latin Church, known as the Tridentine Mass. Pius V declared Thomas Aquinas a Doctor of the Church.

As a cardinal, Ghislieri gained a reputation for putting orthodoxy before personalities, prosecuting eight French bishops for heresy. He also stood firm against nepotism, rebuking his predecessor Pope Pius IV to his face when he wanted to make a 13-year-old member of his family a cardinal and subsidize a nephew from the papal treasury.

By means of the papal bull of 1570, Regnans in Excelsis, Pius V excommunicated Elizabeth I of England for heresy and persecution of English Catholics during her reign. He also arranged the formation of the Holy League, an alliance of Catholic states to combat the advancement of the Ottoman Empire in Eastern Europe. Although outnumbered, the Holy League famously defeated the Ottomans at the Battle of Lepanto in 1571. Pius V attributed the victory to the intercession of the Blessed Virgin Mary and instituted the feast of Our Lady of Victory. Biographers report that as the Battle of Lepanto ended, Pius rose and went over to a window, where he stood gazing toward the East. "...[L]ooking at the sky, he cried out, 'A truce to business; our great task at present is to thank God for the victory which He has just given the Christian army'."
