Vatican City
Vatican City has a reasonably well-developed transport network considering its size (consisting mostly of a piazza and walkways). A state that is long and wide, it has a small transportation system with no airports or highways. The only aviation facility in Vatican City is the Vatican City Heliport. Vatican City is one of the few independent countries without an airport, and is served by the airports that serve the city of Rome, Leonardo da Vinci-Fiumicino Airport, and to a lesser extent Ciampino Airport.
Theocracy
Following the Capture of Rome on 20 September 1870, the Papal States including Rome with the Vatican were annexed by the Kingdom of Italy. In 1929, with the Lateran Treaty signed with the Italian Government, the new state of Vatican City (population 842) – with no connection with the former Papal States – was formally created and recognized as an independent state. The head of state of the Vatican is the pope, elected by the College of Cardinals, an assembly of Senatorial-princes of the Church. They are usually clerics, appointed as Ordinaries, but in the past have also included men who were not bishops nor clerics. A pope is elected for life, and either dies or may resign. The cardinals are appointed by the popes, who therefore choose the electors of their successors.
