Vatican City is an independent city-state enclaved within Rome, Italy. Established with the Lateran Treaty (1929), it is distinct from, yet under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See. With an area of 44 hectares (110 acres), and a population of about 1000, it is the smallest sovereign state in the world by both area and population.
