Vatican City

Vatican City, officially Vatican City State, is a landlocked independent city-state, microstate and enclave within Rome, Italy. It became independent from Italy in 1929 with the Lateran Treaty, and it is a distinct territory under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See, itself a sovereign entity of international law, which maintains the city state's temporal, diplomatic, and spiritual independence. With an area of 49 hectares and a 2019 population of about 453, it is the smallest state in the world both by area and population.
