Vatican City , officially the Vatican City State (Italian: Stato della Città del Vaticano; Latin: Status Civitatis Vaticanae), is a sovereign country, city-state, microstate, and enclave surrounded by, and historically a part of, Rome, Italy. It became independent from Italy in 1929 with the Lateran Treaty, and is a distinct territory under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See, which is itself a sovereign entity under international law, maintaining the city-state's temporal power, governance, diplomatic, and spiritual independence. The Vatican is also a metonym for the pope, the Holy See, and the Roman Curia. The country has the world's smallest land area and the smallest population, with 764 citizens as of 2023.
