Pope Paul III (Latin: Paulus III; Italian: Paolo III; born Alessandro Farnese; 29 February 1468 – 10 November 1549) was head of the Catholic Church and ruler of the Papal States from 13 October 1534 to his death, in November 1549.
Paul III came to the papal throne in the time following the sack of Rome in 1527, which was rife with uncertainties in the Catholic Church as the Protestant Reformation progressed. His pontificate initiated the Catholic Reformation with the Council of Trent in 1545, and witnessed wars of religion in which Emperor Charles V launched military campaigns against the Protestants in Germany. He recognized new Catholic religious orders and societies such as the Jesuits, the Barnabites, and the Congregation of the Oratory. His efforts were distracted by nepotism to advance the power and fortunes of his family, including his illegitimate son Pier Luigi Farnese.
