Vatican City
The name Vatican first appeared in the time of the Roman Republic. It described a marshy area on the west bank of the Tiber River. This land sat between the Janiculum and Monte Mario hills. Ancient Romans called this region Ager Vaticanus, meaning Vatican territory. The poet Martial wrote about the poor quality of wine produced there even after reclamation efforts. Tacitus recorded that soldiers camped in these unhealthy districts during AD 69. He noted many deaths among common soldiery due to disease from drinking the nearby stream water.
Agrippina the Elder drained the area in the early first century AD. She laid out gardens where her son Caligula later built a circus for charioteers. Nero completed this structure which became known as the Circus of Nero. The Vatican obelisk stands today as the last visible remnant from that ancient circus. Caligula brought this stone monument from Heliopolis in Egypt to stand at the center of the spina. Tradition states Saint Peter was crucified upside down within this same circus grounds after the Great Fire of Rome in AD 64.
Opposite the circus lay a cemetery separated by the Via Cornelia street. Funeral monuments and mausoleums were constructed before the Constantinian Basilica of St. Peter rose in the first half of the fourth century. Remains of this ancient necropolis were discovered during renovations by popes throughout centuries. Systematic excavation occurred from 1939 to 1941 under Pope Pius XII. The land mass became more populated following activity around the basilica.
A diplomatic agreement signed on the 11th of February 1929 resolved the Roman Question. Prime Minister Benito Mussolini represented King Victor Emmanuel III while Cardinal Secretary of State Pietro Gasparri spoke for Pope Pius XI. This treaty established the independent state of Vatican City. It took effect on the 7th of June 1929 when ratified by both parties. The document created a new sovereign entity rather than preserving vestiges of the larger Papal States which had covered much of Central Italy between 756 and 1870.
Before this agreement, popes resided within the Vatican walls since 1870 after Rome was annexed by Italian forces. They refused to leave the compound until the dispute ended. Pope Pius IX served as the last ruler of the Papal States before losing secular power. He became known as a prisoner in the Vatican during those decades. The Lateran Treaty granted the Holy See temporal jurisdiction over a small territory while reaffirming Catholic Christianity's special status in Italy.
The boundaries of the proposed territory were influenced by existing fortification walls built under Paul III, Pius IV, and Urban VIII. Some tracts lacked physical walls but used building lines as boundaries. A modern wall was constructed for a small part of the frontier. St. Peter's Square remains distinguished from Italian territory only by a white line along its limit where it touches Piazza Pio XII.
Vatican City operates as an absolute elective monarchy governed by the Holy See. The pope holds principal legislative, executive, and judicial power over the state. This makes him the only absolute monarch remaining in Europe today. Legislative authority is managed in the pope's name by the Pontifical Commission for Vatican City State. Cardinals appointed by the pope serve five-year terms on this commission.
Executive power rests with the president of that commission who also serves as president of the governorate. General secretaries assist this leader in daily operations. Foreign relations belong to the Holy See's Secretariat of State rather than the city-state itself. The cardinal camerlengo presides over the Apostolic Camera during sede vacante periods when the papal throne stands empty. Three other cardinals chosen by lot every three days help administer property and rights during these vacancies.
Pope Leo XIV born Robert Francis Prevost in Chicago became head of state on the 8th of May 2025. Raffaella Petrini serves as president of the Governorate since the 1st of March 2025 after appointment by Pope Francis. She was reconfirmed by Pope Leo XIV on the 9th of May 2025. Judicial functions operate through four bodies including a Supreme Court and Tribunal established under codes from 2013.
The Pontifical Swiss Guard was founded by Pope Julius II on the 22nd of January 1506. These soldiers remain responsible for personal security of the pope and residents within Vatican City. All recruits must be Catholic unmarried males between ages 19 and 30 with Swiss citizenship. They complete basic training with Swiss Armed Forces before joining. Members carry small arms and traditional halberds while wearing distinctive uniforms.
In 2005 the Guard numbered 134 members according to official records. The Corps of Gendarmerie handles public order border control traffic regulation and criminal investigation duties. This force maintains 130 personnel working under the Directorate for Security Services and Civil Defence. The Palatine Guard and Noble Guard disbanded in 1970 under Pope Paul VI leaving only these two active units.
Civil defence falls to the Corps of Firefighters established in 1941. They manage fire fighting flooding natural disasters and mass casualty incidents. A bunker inaugurated in 1980 stores extensive historical documents under reinforced concrete vaults. St. Peter's Square remains normally safeguarded by Italian police forces despite being part of Vatican territory.
Financial reports showed a surplus of 6.7 million euros in 2007 but deficits exceeding 15 million euros appeared in 2008. The US Department of State listed Vatican City among nations of concern for money laundering in 2012. Cardinal George Pell headed a secretariat for economy announced in February 2014 after charging senior clerics with offences. Pope Francis appointed an auditor-general authorized to audit any agency at any time.
Tourist foot traffic creates high per-capita crime rates focused on purse snatching and pickpocketing in St. Peter's Square. Perpetrators arrested there face trial by Italian authorities since Italian police patrol that area daily. The state runs no prison system except detention cells for pre-trial confinement. Convicted individuals serve terms in Italian prisons paid for by Vatican funds.
St. Peter's Basilica stands as a renowned work of Renaissance architecture designed by Bramante Michelangelo Giacomo della Porta Carlo Maderno and Gian Lorenzo Bernini. The Sistine Chapel displays frescoes including works by Perugino Domenico Ghirlandaio Sandro Botticelli plus ceiling and Last Judgment paintings by Michelangelo. Raphael and Fra Angelico decorated interior spaces throughout the complex.
UNESCO added the Vatican to
its World Heritage Sites list in 1984 making it the only site consisting entirely of one state. It holds registration in the International Register of Cultural Property under Special Protection according to the 1954 Hague Convention. The Vatican Apostolic Library houses collections of highest historical scientific and cultural importance alongside museum treasures.
Guided tours access gardens and excavations beneath the basilica while general public enters Saint Peter's Square freely. Tickets free of charge required beforehand for papal audiences held in halls adjacent to major ceremonies. The Vatican Museums incorporate the Sistine Chapel charging entrance fees for most visitors. New wings built by Raffaele Stern between 1774 and 1820 expanded exhibition space significantly.
Pope Pius XI founded the Pontifical Academy of Sciences in 1936 following earlier efforts by Pope Pius IX in 1847. This academy brings together mathematicians physicists natural scientists and medical experts contributing to epistemological studies and history of science. Members include astrophysicist Martin John Rees mathematician Cédric Villani theoretical physicist Edward Witten plus Nobel laureates Jennifer Doudna Emmanuelle Charpentier Ernest
Rutherford Luigi Luca Cavalli-Sforza Francis Collins Robert J. White Alexander Fleming.
The Vatican Observatory dates back to the sixteenth century continuing contributions through partnerships with University of Arizona institutions. It operates infrared and optical telescopes including the Vatican Advanced Technology Telescope located there. Research focuses on cosmological models stellar classification binary stars nebulae philosophical interdisciplinary studies at Berkeley California centers.
First telescopes installed in Vatican Gardens near St. Peter's Basilica became useless due to light pollution in the 1930s. Pope Pius XI moved operations to Castel Gandolfo extraterritorial palace subsequently. The observatory maintains an extensive library containing meteorite collections while participating in International Astronomical Union activities.
