Vatican City, officially the State of the Vatican City (Italian: Stato della Città del Vaticano), is a landlocked sovereign city-state whose territory consists of a walled enclave within the city of Rome, the capital city of Italy. At approximately 44 hectares (110 acres), and with a population of around 900, it is the smallest country in the world by area. 
The Vatican City is a city-state that came into existence in 1929 and is thus clearly distinct from the central authority of the Roman Catholic Church, known as the Holy See, which existed long before 1929. Ordinances of Vatican City are published in Italian. Official documents of the Holy See are issued mainly in Latin. The two entities even have distinct passports: the Holy See, not being a country, only issues diplomatic and service passports; the state of Vatican City issues normal passports. In both cases the passports issued are very few.
The Lateran Treaty in 1929, which brought the city-state into existence, spoke of it as a new creation, not as a vestige of the much larger Papal States (756-1870) that had previously encompassed central Italy. Most of this territory was absorbed into the Kingdom of Italy in 1860, and the final portion, namely the city of Rome with a small area close to it, ten years later, in 1870.
