Lateran Treaty
The Lateran Treaty (; ) was one of the Lateran Pacts of 1929 or Lateran Accords, agreements made in 1929 between the Kingdom of Italy and the Holy See, settling the "Roman Question". They are named after the Lateran Palace, where they were signed on 11 February 1929. The Italian parliament ratified them on 7 June 1929. It recognized Vatican City as an independent state, with the Italian government, at the time led by Benito Mussolini as prime minister, agreeing to give the Roman Catholic Church financial compensation for the loss of the Papal States. In 1947, the Lateran Treaty was recognized in the Constitution of Italy as regulating the relations between the state and the Catholic Church.
Treaty of London (1915)
London Pact (), or more correctly, the Treaty of London, 1915, was a secret pact between the Triple Entente and the Kingdom of Italy. The treaty was signed in London on 26 April 1915 by the United Kingdom of Great Britain and Ireland, the French Third Republic, the Russian Empire, and the Kingdom of Italy. Its intent was to gain the alliance of Italy against its former allies, including the German Empire and Austria-Hungary. The main lure was promising large swaths of Austria-Hungary to the north of Italy and to the east across the Adriatic. Britain also promised funding. Italy promised to enter the war the next month. The alliance with Italy's old enemy Austria had been promoted by some politicians as a realpolitik move and had never been popular with the public. Also, the Allies could easily outbid Austria-Hungary and thereby won a military alliance with 36 million Italians. The secret provisions were published by the Bolsheviks when they came to power in Russia in late 1917.
