Vatican City, officially the Vatican City State, is a landlocked independent country, city-state, microstate, and enclave within Rome, Italy. It became independent from Italy in 1929 with the Lateran Treaty, and it is a distinct territory under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See, itself a sovereign entity under international law, which maintains the city-state's temporal power and governance, diplomatic, and spiritual independence.
The Vatican City State is a neutral nation, which has not engaged in any war since its formation in 1929 by the Lateran Treaty. It has no formal military compact or agreement with neighbouring Italy, although responsibility for defending the Vatican City from an international aggressor is likely to lie primarily with the Italian Armed Forces. When presenting the Lateran Treaty to the Italian parliament in 1929, Benito Mussolini declared: "It is evident that we [the Italian state] will be the necessary guarantors of this neutrality and inviolability [of Vatican City], since, in the remote hypothesis someone wanted to hurt her, he would first have to violate our territory." Although the Vatican City state has never been at war, it was exposed, together with properties of the Holy See in Rome, to bombings during World War II.
Pope Pius IX was head of the Catholic Church from 1846 to 1878. His reign of 32 years is the longest of any pope in history. He was notable for convoking the First Vatican Council in 1868 and for permanently losing control of the Papal States in 1870 to the Kingdom of Italy. Thereafter, he refused to leave Vatican City, declaring himself a "prisoner in the Vatican".
The Papal States, officially the State of the Church, were a conglomeration of territories on the Apennine Peninsula under the direct sovereign rule of the pope from 756 until 1870. They were among the major states of Italy from the 8th century until the Unification of Italy, between 1859 and 1870.
Pope Pius VII was head of the Catholic Church from 14 March 1800 to his death in August 1823. He ruled the Papal States from June 1800 to 17 May 1809 and again from 1814 to his death. Chiaramonti was also a monk of the Order of Saint Benedict in addition to being a well-known theologian and bishop.
The Holy See exercised political and secular influence, as distinguished from its spiritual and pastoral activity, while the pope ruled the Papal States in central Italy.
The Palatine Guard was a military unit of the Vatican. It was formed in 1850 by Pope Pius IX, who ordered that the two militia units of the Papal States be amalgamated. The corps was formed as an infantry unit, and took part in watch-keeping in Rome. The only occasion on which it saw active service was during the token resistance on 20 September 1870 to the occupation of Rome by Italian government troops.
The Prince Assistant to the Papal Throne was a hereditary title of nobility available in the Papal Court from the early 16th century until the reforms of Pontificalis Domus by Pope Paul VI in 1968, when the Papal Court was reformed into the current Papal Household. The title is not currently in use, though it has not been formally suppressed.
The Roman question was a dispute regarding the temporal power of the popes as rulers of a civil territory in the context of the Italian Risorgimento. It ended with the Lateran Pacts between King Victor Emmanuel III of Italy and Pope Pius XI in 1929.
The Napoleon Tiara was a papal tiara given to Pope Pius VII in June 1805 a few months after he presided at the coronation of Napoleon I and Joséphine de Beauharnais. While lavishly decorated with jewels, it was deliberately too small and heavy to be worn and meant as an insult to the Pope. In the painting of The Coronation of Napoleon by Jacques-Louis David, the tiara is held behind the Pope by one of his aides.
The black nobility or black aristocracy are Roman aristocratic families who sided with the Papacy under Pope Pius IX after the Savoy family-led army of the Kingdom of Italy entered Rome on 20 September 1870, overthrew the Pope and the Papal States, and took over the Quirinal Palace, and any nobles subsequently ennobled by the Pope prior to the 1929 Lateran Treaty.
The Gendarmerie Corps of Vatican City State is the gendarmerie, or military police and security force, of Vatican City, Holy See and its extraterritorial properties. It was founded in 1816 as Corps of Gendarmes by Pope Pius VII, renamed the Central Security Office in 1970, the Security Corps in 1991, and was restored to its original name in 2002.
The Capture of Rome on 20 September 1870 was the final event of the unification of Italy (Risorgimento), marking both the final defeat of the Papal States under Pope Pius IX and the unification of most of the Italian Peninsula under the Kingdom of Italy, a constitutional monarchy.
The Roman Court or Papal Curia was reformed by the papal bull Pontificalis Domus issues by Pope Paul VI in 1969. It abolished the role of the old Roman nobility at the papal court with the exception of the position of Prince Assistant to the Papal Throne. The titles abolished, such as the Grand Master of the Sacred Apostolic Hospice and Marshal of the Holy Roman Church and the Sacred Conclave, remain heredity but are now purely honorary.
The Corsican Guard was a military unit of the Papal States composed exclusively of Corsican mercenaries on duty in Rome, having the functions of an urban militia and guard for the Pope.
The Pontifical Swiss Guard is an armed force and honour guard unit maintained by the Holy See that protects the Pope and the Apostolic Palace within the territory of the Vatican City State. Established in 1506 under Pope Julius II, the Pontifical Swiss Guard is among the oldest military units in continuous operation.
The Papal Zouaves were an infantry battalion, later regiment, dedicated to defending the Papal States. Named after the French zouave regiments, the Zuavi Pontifici were mainly young men, unmarried and Catholic, who volunteered to assist Pope Pius IX in his struggle against the Italian unificationist Risorgimento.
Pontificalis Domus was a motu proprio document issued by Pope Paul VI on 28 March 1968, in the fifth year of his pontificate. It reorganized the Papal Household, which had been known until then as the Papal Court.
The Corps of Firefighters of the Vatican City State is the fire brigade of the Vatican City State. It was founded in its present form by Pope Pius XII in 1941, although its origins are much older.
The papal nobility are the aristocracy of the Holy See, composed of persons holding titles bestowed by the Pope. From the Middle Ages into the nineteenth century, the papacy held direct temporal power in the Papal States, and many titles of papal nobility were derived from fiefs with territorial privileges attached. During this time, the Pope also bestowed ancient civic titles such as patrician. Today, the Pope still exercises authority to grant titles with territorial designations, although these are purely nominal and the privileges enjoyed by the holders pertain to styles of address and heraldry. Additionally, the Pope grants personal and familial titles that carry no territorial designation. Their titles being merely honorific, the modern papal nobility includes descendants of ancient Roman families as well as notable Catholics from many countries. All pontifical noble titles are within the personal gift of the pontiff, and are not recorded in the Official Acts of the Holy See.
