, he was elected as the new pope by the cardinals on 28 September 1823, taking the name of Leo XII. His election had been facilitated because he was thought to be close to death, but he unexpectedly rallied. He had even remarked about his own health to the cardinals, saying that they would be electing "a dead man". It was said in the conclave that he lifted his robes to show the cardinals a pair of swollen and ulcerated legs to deter them, but that made them even more eager to elect him. Before the conclave opened, the

While it was later indicated that the French court would not be amenable to the election of della Genga, Severoli's voting bloc decided to cast their votes for della Genga, seeing him receive 34 votes to become pope. Leo XII was 63 at the time of his election and frequently fell victim to infirmities. He was tall and thin with an ascetic look and a melancholic countenance. At this time Vincent Strambi served as bishop for the remainder of the pontificate of

Domestic policy

Leo XII's domestic policy was one of extreme conservatism: "He was determined to change the condition of society, bringing it back to the utmost of his power to the old usages and ordinances, which he deemed to be admirable; and he pursued that object with never flagging zeal." He condemned the Bible societies, and under

Laws such as that forbidding Jews to own property and allowing them only the shortest possible time in which to sell what they owned, and that requiring all Roman residents to listen to Catholic catechism commentary, led many of Rome's Jews to emigrate, to

In a regime that saw the division of the population into

. The pope also denied the Jews the right to possess material possessions and allowed them the shortest time to sell their belongings. He revived the regulations of the Middle Ages in regard to segregation and marks for identification. While often considered an archconservative Leo XII held a high opinion of the liberal Catholic priest Lamennais having a portrait of him hung in his private chambers. When the latter visited Rome in 1824 Leo offered him a Vatican apartment and in 1828 a cardinalate. According to Cardinal Nicholas Wiseman before the full

he said that Lamennais was " a distinguished writer, whose works had not only rendered eminent services to religion, but rejoiced and astonished Europe." However some believe that the quote was actually about the historian John Lingard. Leo XII had a fascination with archeology. When Jean-François Champollion deciphered the

, Leo XII invited him to Rome to study its obelisks. Leo XII later printed and engraved Champollion's work at his personal expense. Champollion later wrote to Cardinal Wiseman that "It is a real service which His Holiness renders to science, and I shall be happy if you will be good enough to place at his feet the homage of my profound acknowledgment.


Vaccination controversy

According to some contemporary authors such as G. S. Godkin, Leo XII was also said to have prohibited
vaccination Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating ...
. More recent scholarship has been unable to find any ban or any suggestion of a ban by Leo XII and his administration. Donald J. Keefe traced a quote by Leo XII which strongly condemned vaccination to "an unverified citation" by Dr. Pierre Simon in ''Histoire et philosophie du contrôle des naissances''. The response of the Papacy to the arrival of vaccination in Italy has been documented in ''Pratique de la vaccination antivariolique dans les provinces de l’État pontifical au 19ème siècle'', an article written by Yves-Marie Bercé and Jean-Claude Otteni for Revue d’Histoire Ecclésiastique. According to Bercé and Otteni, the biographers and contemporaries of Leo XII do not mention any interdict. The authors credit the origin of the mythical vaccination ban of Leo XII to the personality of Cardinal della Genga when he became pope in 1823. His intransigence and piety alienated liberal opinion very quickly. His austere spirituality made him the target of criticisms and mocking remarks. English travelers visiting the peninsula and many of the diplomats established in Rome remarked on the severity of the pontiff. The absence of a prohibition is evidenced by the fact that in 1828 the Medical-Surgical Society of Bologna was able to implement a vaccination campaign.

Jubilee

Leo XII celebrated the jubilee in 1825 in an event that saw more than half a million pilgrims travel to Rome to participate in the solemnities. To mark the event, Leo XII issued the encyclical ''Quod hoc ineunte'' on 24 May 1825 that proclaimed the jubilee.


Consistories

He held 8 consistories in which he elevated 25 new cardinals into the cardinalate. This included Cardinal Bartolomeo Alberto Cappellari – the future

– on 13 March 1826. In addition, Leo XII nominated three cardinals whom he reserved "'' in pectore''" but later revealed. For the December 1824 allocations, Leo XII considered elevating Félicité de La Mennais despite knowing about his crude character and extreme social and moral positions. Nevertheless, the nomination never occurred, however, other sources allege that he declined the pope's invitation. For the October 1826 allocation, Leo XII had nominated one cardinal ''in pectore'' whom he later revealed in 1828, however, several subsequent sources indicate that the renowned English historian John Lingard was also created a cardinal ''in pectore'' and simply never announced. In the 1828 consistory, the Bishop of Osimo e Cingoli Timoteo Maria Ascensi was to be made a cardinal but died nine days before the consistory occurred.
