use during the papal conclave of 1644. He was created Cardinal in pectore in 1627 and published in 1629. Papacy Election The 1644 conclave for the election of a successor to Pope Urban VIII was long and contentious, lasting from 9 August to 15 September. A large French faction led by Urban VIII's nephews objected to the Spanish candidate, as an enemy of Cardinal Mazarin, who guided French policy. They put up their own candidate (Giulio Cesare Sacchetti) but could not establish enough support for him and agreed to Cardinal Pamphili as an acceptable compromise, though he had served as legate to Spain. Mazarin, bearing the French veto of Pamphili, arrived too late, and the election was accomplished. Relations with France Pamphili chose to be called Innocent X. Soon after his accession he initiated legal action against the Barberini for misappropriation of public funds. The brothers Francesco Barberini, Antonio Barberini and Taddeo Barberini fled to Paris, where they found a powerful protector in Cardinal Mazarin. Innocent X confiscated their property, and on 19 February 1646, issued a papal bull decreeing that all cardinals who might leave the Papal States for six months without express papal permission would be deprived of their benefices and eventually of their cardinalate itself. The French parliament declared the papal ordinance void in France, but Innocent X did not yield until Mazarin prepared to send troops to Italy. Henceforth the papal policy towards France became more friendly, and somewhat later the Barberini were rehabilitated when the son of Taddeo Barberini, Maffeo Barberini, married Olimpia Giustiniani, a niece of Innocent X. In 1653, Innocent X, with the Cum occasione papal bull, condemned five propositions of Jansenius's Augustinus, as heretical and close to Lutheranism. This led to the formulary controversy, Blaise Pascal's writing of the Lettres Provinciales, and finally to the razing of the Jansenist convent of Port-Royal and the subsequent dissolving of its community. Relations with Parma The death of Pope Urban VIII is said to have been hastened by his chagrin at the result of the First War of Castro, a war he had undertaken against Odoardo Farnese, the duke of Parma. Hostilities between the papacy and the Duchy of Parma resumed in 1649, and forces loyal to Pope Innocent X destroyed the city of Castro on 2 September 1649. Innocent X objected to the conclusion of the Peace of Westphalia, which his nuncio, Fabio Chigi,
