(Pietro Francesco Orsini) (1724-1730) Born Gravina, Naples, 1649; died Rome. He became a Dominican, was made a cardinal, 1672, and was appointed successively bishop of Manfredonia, Cesena, and Benevento. As pope he was a disciplinarian, instituting numerous reforms and requiring absolute acceptance of the Bull "Unigenitus against Jansenism. In diplomatic affairs he lacked firmness, settling the controversy between the Kings of Naples, Savoy, and Portugal in an indecisive manner. His reputation suffered through his misplaced trust in Cardinal Coscia.
