Pope Pius V

Who was Pope Pius V?

Pope Pius V, born Antonio Ghislieri, was the head of the Catholic Church from 7 January 1566 to his death in 1572. He is venerated as a saint of the Catholic Church. He is chiefly notable for his role in the Council of Trent, the Counter-Reformation, and the standardization of the Roman rite within the Latin Church. Pius V declared Thomas Aquinas a Doctor of the Church and patronized prominent sacred music composer Giovanni Pierluigi da Palestrina.

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 subsidise a nephew from the Papal treasury.

In affairs of state, Pius V excommunicated Elizabeth I of England for schism and persecution of English Catholics during her reign. He also arranged the formation of the Holy League, an alliance of Catholic states. Although outnumbered, the Holy League famously defeated the Ottoman Empire, which had threatened to overrun Europe, at the Battle of Lepanto. This victory Pius V attributed to the intercession of the Blessed Virgin Mary and instituted the feast of Our Lady of Victory.
