Outline of Vatican City
Vatican City – an ecclesiastical or sacerdotal-monarchical state, being the sovereign territory of the Holy See and ruled by the Bishop of Rome—the Pope, the leader of the worldwide Catholic Church. The territory of this landlocked sovereign city-state consists of a walled enclave within the city of Rome, Italy. It has an area of approximately , and a population of just over 800. This makes Vatican City the smallest independent state in the world by both area and population.Geography of Vatican CityVatican City is an enclave in an urban area, and lacks the geographic features common to (much larger) countries:Demographics of Vatican City
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.
