Lateran Treaty
Negotiations for the settlement of the Roman Question began in 1926 between the government of Italy and the Holy See, and culminated in the agreements of the Lateran Pacts, signed—the Treaty says—for King Victor Emmanuel III of Italy by Benito Mussolini, Prime Minister and Head of Government, and for Pope Pius XI by Pietro Gasparri, Cardinal Secretary of State, on 11 February 1929. It was ratified on 7 June 1929. The agreements were signed in the Lateran Palace, hence the name by which they are known.
Treaty of Rapallo (1920)
The treaty was signed on 12 November 1920 in Rapallo, near Genoa, Italy. Tension between Italy and Yugoslavia arose at the end of World War I, when the Austro-Hungarian Empire dissolved and Italy claimed the territories assigned to it by the secret London Pact of 1915. According to the pact, signed in London on 26 April 1915 by the Kingdom of Italy and Triple Entente, in case of victory at the end of World War I, Italy was to obtain several territorial gains including former Austrian Littoral, Northern Dalmatia and notably Zadar (Zara), Šibenik (Sebenico), and most of the Dalmatian islands (except Krk and Rab).
