History

The name "Vatican" was already in use in the time of the Roman Republic for the Ager Vaticanus, a marshy area on the west bank of the Tiber across from the city of Rome, located between the Janiculum, the Vatican Hill and Monte Mario, down to the Aventine Hill and up to the confluence of the Cremera creek.

Because of its vicinity to their arch-fiend, the Etruscan city of Veii (another naming for the Ager Vaticanus was Ripa Veientana or Ripa Etrusca) and for being subjected to the floods of the Tiber, the Romans considered this originally uninhabited part of Rome insalubrious and ominous.

The particularly low quality of Vatican wine, even after the reclamation of the area, was commented on by the poet Martial  Tacitus wrote, that in AD 69, the Year of the Four Emperors, when the northern army that brought Vitellius to power arrived in Rome, "a large proportion camped in the unhealthy districts of the Vatican, which resulted in many deaths among the common soldiery; and the Tiber being close by, the inability of the Gauls and Germans to bear the heat and the consequent greed with which they drank from the stream weakened their bodies, which were already an easy prey to disease".

The toponym Ager Vaticanus is attested until the 1st century AD: afterwards, another toponym appeared, Vaticanus, denoting an area much more restricted: the Vatican hill, today's St. Peter's Square, and possibly today's Via della Conciliazione.

Under the Roman Empire, many villas were constructed there, after Agrippina the Elder (14 BC-18 October AD 33) drained the area and laid out her gardens in the early 1st century AD. In AD 40, her son, Emperor Caligula (31 August AD 12-24 January AD 41; r. 37-41) built in her gardens a circus for charioteers (AD 40) that was later completed by Nero, the Circus Gaii et Neronis, usually called, simply, the Circus of Nero.

The Vatican Obelisk was originally taken by Caligula from Heliopolis in Egypt to decorate the spina of his circus and is thus its last visible remnant. This area became the site of martyrdom of many Christians after the Great Fire of Rome in AD 64. Ancient tradition holds that it was in this circus that Saint Peter was crucified upside-down.

Opposite the circus was a cemetery separated by the Via Cornelia. Funeral monuments and mausoleums, and small tombs, as well as altars to pagan gods of all kinds of polytheistic religions, were constructed lasting until before the construction of the Constantinian Basilica of St. Peter in the first half of the 4th century. A shrine dedicated to the Phrygian goddess Cybele and her consort Attis remained active long after the ancient Basilica of St. Peter was built nearby. Remains of this ancient necropolis were brought to light sporadically during renovations by various popes throughout the centuries, increasing in frequency during the Renaissance until it was systematically excavated by orders of Pope Pius XII from 1939 to 1941. The Constantinian basilica was built in 326 over what was believed to be the tomb of Saint Peter, buried in that cemetery.

From then on, the area became more populated in connection with activity at the basilica. A palace was constructed nearby as early as the 5th century during the pontificate of Pope Symmachus (reigned 498-514)

Political system

The government of Vatican City has a unique structure. The pope is the sovereign of the state. Legislative authority is vested in the Pontifical Commission for Vatican City State, a body of cardinals appointed by the pope for five-year periods. Executive power is in the hands of the president of that commission, assisted by the general secretary and deputy general secretary. The state's foreign relations are entrusted to the Holy See's Secretariat of State and diplomatic service. Nevertheless, the pope has absolute power in the executive, legislative, and judicial branches over Vatican City. As the ex officio "Prince" of Vatican City, the Pope is the only absolute monarch in Europe.

There are departments that deal with health, security, telecommunications, etc.

The Cardinal Camerlengo presides over the Apostolic Camera to which is entrusted the administration of the property and protection of other papal temporal powers and rights of the Holy See during the period of the empty throne or sede vacante (papal vacancy). Those of the Vatican State remain under the control of the Pontifical Commission for the State of Vatican City. Acting with three other cardinals chosen by lot every three days, one from each order of cardinals (cardinal bishop, cardinal priest, and cardinal deacon), he in a sense performs during that period the functions of head of state of Vatican City.[citation needed] All the decisions these four cardinals take must be approved by the College of Cardinals as a whole.

The nobility that was closely associated with the Holy See at the time of the Papal States continued to be associated with the Papal Court after the loss of these territories, generally with merely nominal duties (see Papal Master of the Horse, Prefecture of the Pontifical Household, Hereditary officers of the Roman Curia, Black Nobility). They also formed the ceremonial Noble Guard. In the first decades of the existence of the Vatican City State, executive functions were entrusted to some of them, including that of delegate for the State of Vatican City (now denominated president of the Commission for Vatican City). But with the motu proprio Pontificalis Domus of 28 March 1968, Pope Paul VI abolished the honorary positions that had continued to exist until then, such as Quartermaster general and Master of the Horse.

Vatican City State, created in 1929 by the Lateran Pacts, provides the Holy See with a temporal jurisdiction and independence within a small territory. It is distinct from the Holy See. The state can thus be deemed a significant but not essential instrument of the Holy See. The Holy See itself has existed continuously as a juridical entity since Roman Imperial times and has been internationally recognized as a powerful and independent sovereign entity since Late Antiquity to the present, without interruption even at times when it was deprived of territory (e.g. 1870 to 1929). The Holy See has the oldest active continuous diplomatic service in the world, dating back to at least AD 325 with its legation to the Council of Nicea.

The Pope is ex officio head of state of Vatican City since the 1860s, functions dependent on his primordial function as bishop of the diocese of Rome. The term "Holy See" refers not to the Vatican state but to the Pope's spiritual and pastoral governance, largely exercised through the Roman Curia.[68] His official title with regard to Vatican City is Sovereign of the State of the Vatican City.

Pope Francis, born Jorge Mario Bergoglio in Buenos Aires, Argentina, was elected on 13 March 2013. His principal subordinate government official for Vatican City as well as the country's head of government is the President of the Pontifical Commission for Vatican City State, who since 1952 exercises the functions previously belonging to the Governor of Vatican City. Since 2001, the president of the Pontifical Commission for Vatican City State also has the title of president of the Governorate of the State of Vatican City. The president is Italian Cardinal Giuseppe Bertello, who was appointed on 1 October 2011.
