Vatican City

Vatican City, officially the Vatican City State, is a landlocked sovereign state and city-state; it is enclaved within Rome, the capital city of Italy and seat of the Catholic Church. It became independent from the Kingdom of Italy in 1929 with the Lateran Treaty. It is governed by the Holy See, itself a sovereign entity under international law, which maintains its temporal power, governance, diplomacy, and spiritual independence. Vatican is also used as a metonym for the pope, the central authority of the Roman Catholic Church, and the Holy See and the Roman Curia.
