'''Pope Leo XII''' ({{langx|it|Leone XII}}; born '''Annibale Francesco Clemente Melchiorre Girolamo Nicola della Genga'''; 2 August 1760&nbsp;– 10 February 1829) was head of the [[Catholic Church]] and ruler of the [[Papal States]] from 28 September 1823 to his death in February 1829.'''<ref>For the correct biographical information, date and place of birth and surname, see Ph. Boutry, ''Souverain et Pontife. Recherche prosographiques sur la Curie romaine à l'age de la Restauration (1814–1846)'', Roma, Ecole francaise, 2002. pp. 359–361.</ref>'''

Leo XII was in ill health from the time of his [[Papal conclave|election]] to the [[papacy]] to his death less than 6 years later, though he was noted for enduring pain well. He was a deeply conservative ruler, who enforced many controversial laws, including one forbidding Jews to own property. Though he raised taxes, the Papal States remained financially poor.
