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 Sèvres
Hostilities with Britain over the neutral zone of the Straits were narrowly avoided in the Chanak Crisis of September 1922, when the Armistice of Mudanya was concluded on 11 October, which led the former Allies of World War I to return to the negotiating table with the Turks in November 1922. This culminated in 1923 in the Treaty of Lausanne, which replaced the Treaty of Sèvres and restored large territory in Anatolia and Thrace to the Turks. Terms in the Treaty of Lausanne that were different from those in the Treaty of Sèvres included France and Italy only having areas of economic interaction rather than zones of influence; Constantinople was not opened as an international city; and there was to be a demilitarized zone between Turkey and Bulgaria.
