The Lateran Treaty of 1929 was negotiated and signed by the Kingdom of Italy and the Holy See. The treaty recognized the Vatican City as an independence sovereign state. The Papal states had ruled several of the Italian states prior to the unification of Italy, an event evolving throughout the 19th century. One by one, these states were incorporated into the unified nation of Italy either by force or treaty until nothing remained of the Papal States except the Vatican City.
