AP European History
Pope Paul IV, born Giovanni Pietro Carafa, was the head of the Catholic Church from 1555 to 1559 and is best known for his staunch opposition to Protestantism and his role in the Catholic Reformation. His papacy marked a significant moment in the Wars of Religion, particularly with the establishment of the Roman Inquisition and the Index of Forbidden Books, which aimed to combat heresy and maintain Catholic orthodoxy. Paul IV's policies and reforms had lasting impacts on both the church and its relationship with various European states during a time of great religious conflict.
