Pius V, Antonio Etrislieri (1504–1572)

Pope from 1566. His early career was in the Inquisition, a role which brought him the support of Paul IV who made him a cardinal in 1558. From the beginning of his own pontificate, he stressed his determination to carry out the reforms of the Council of Trent. He also excommunicated Elizabeth I of England, and organized the expedition against the Turks that won the victory of Lepanto.
