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
Holy See
Although the Holy See is sometimes metonymically referred to as the "Vatican", the Vatican City State was distinctively established with the Lateran Treaty (1929) between the Holy See and Italy to ensure the temporal, diplomatic, and spiritual independence of the Papacy. As such, ambassadors are officially accredited to the Holy See and not the Vatican City State. Conversely, Papal nuncios to states and international organisations are recognised as representing the Holy See and the integrity of the Catholic Church along with its 1.3 billion members, not the Vatican City State, as prescribed also in the Canon law of the Catholic Church (1983). The "Holy See" thus refers to the See of Rome viewed as the central government of the Catholic Church. The Catholic Church, in turn, is the largest non-government provider of education and health care in the world, while the diplomatic status of the Holy See facilitates the access of its vast international network of charities.
