Pope Pius VIII

Pope Pius VIII (Italian: Pio VIII; born Francesco Saverio Maria Felice Castiglioni; 20 November 1761 – 30 November 1830) was head of the Catholic Church and ruler of the Papal States from 31 March 1829 to his death in November 1830.

Pius VIII's pontificate was the shortest of the 19th century, and is likely the least remembered. His brief papacy witnessed the Catholic Emancipation in the United Kingdom in 1829, which he welcomed, and the July Revolution in France in 1830, which he accepted with reluctance. Pius VIII is often remembered for his writings on marriages between Catholics and Protestants: in the 1830 brief Litteris altero abhinc, he declared that a marriage could only be properly blessed if proper provisions had been made to ensure the bringing up of children in the Catholic faith. His death less than two years after his election to the papacy led to speculation of possible murder.

Francesco Saverio Castiglioni was born in Cingoli, Marche, the third of eight children of Count Ottavio Castiglioni (1714 - 1804) and his wife Sanzia/Sancia Teresa Ghislieri. His brother Filippo Giulio Castiglioni (1774 - 1846) married and had Radegonda Nazzarena Castiglioni, born in 1810, who was married to a maternal nephew of Pope Pius IX. His baptismal name was recorded as Francesco Saverio Maria Felice. An ancestor of his was Pope Celestine IV. He studied at the Collegio Campana run by the Society of Jesus and, after that, at the University of Bologna, where he earned a doctorate in canon and civil law (utroque iure) in 1785. He was ordained to the priesthood in Rome on 17 December 1785.

He served as the Vicar General of Anagni (1788–1790), Fano (1790–1797) and Ascoli Piceno (1797–1800).

On 11 August 1800 Castiglioni was appointed Bishop of Montalto. He received episcopal consecration on 17 August in Rome at the Church of Santi Domenico e Sisto. Cardinal Giuseppe Doria Pamphili served as consecrator, assisted by Nicola Buschi and Camillo Campanelli. He refused to swear allegiance to Napoleon or to his client state, the Kingdom of Italy. On 29 July 1808 he was arrested and taken to Milan. Castiglioni was subsequently taken to Pavia, to Mantua, and then to Turin, where he arrived on 10 November 1813. On 18 November he was brought back to Milan. Finally, after Napoleon fell, Castiglioni returned to his diocese on 16 June 1814. He was praised by Pope Pius VII who in 1816 elevated him to the cardinalate as the Cardinal-Priest of Santa Maria in Traspontina. He held various high offices thereafter, including that of Apostolic Penitentiary. He soon became a Cardinal-Bishop of the suburbicarian see of Frascati.

Castiglioni was considered a front-runner in the conclave of 1823. He was known to be close to Pius VII, who often referred to Castiglioni as "Pius VIII". However, he failed to gain the necessary votes, in part due to controversy surrounding an alliance between him and another favorite, Secretary of State Ercole Consalvi. Annibale Cardinal della Genga was elected instead, and he took the name of Pope Leo XII. Leo XII stated that Castiglioni would one day be called "Pius VIII".

After the death of Pope Leo XII in 1829, Castiglioni, who had all the qualities and skills required to be pope, was again considered to be a major candidate, though was questioned due to his frail health and age. Despite these concerns, he was elected as pope in the papal conclave of 1829. Given that both Popes Pius VII and Leo XII had referred to him as Pius VIII, it seemed only suitable that it was the pontifical name that he chose. He was crowned on 5 April 1829 by Cardinal Giuseppe Albani.

Throughout the conclave, Cardinal Albani settled on proposing Castiglioni as a candidate for the papacy on the basis that his infirmities and age would see a short papacy in which he could persuade the ailing pontiff to hand over aspects of governance to himself. This was on the basis that Albani did not desire to be pope, but rather to be appointed as Cardinal Secretary of State in which he would hold power in terms of ecclesial governance. Albani approached Castiglioni with his offer, drawing up an agreement which Castiglioni signed without demur. With Castiglioni elected, Albani ended up being appointed to his desired posting.
