NoemvrianaThe Noemvriana (Νοεμβριανά, "November Events") of , or the Greek Vespers (after the Sicilian Vespers), was a political dispute which led to an armed confrontation in Athens between the royalist government of Greece and the forces of the Allies over the issue of Greece's neutrality during World War I. Friction existed between the two sides from the beginning of World War I. The unconditional surrender of the border fortress of Roupel in May 1916 to the Central Powers' forces, mainly composed of Bulgarian troops, was the first event that led to the Noemvriana.
Population exchange between Greece and TurkeyThe 1923 population exchange between Greece and Turkey (I Antallagí, Mübâdele, Mübadele) stemmed from the "Convention Concerning the Exchange of Greek and Turkish Populations" signed at Lausanne, Switzerland, on 30 January 1923, by the governments of Greece and Turkey. It involved at least 1.6 million people (1,221,489 Greek Orthodox from Asia Minor, Eastern Thrace, the Pontic Alps and the Caucasus, and 355,000–400,000 Muslims from Greece), most of whom were forcibly made refugees and de jure denaturalized from their homelands.
National SchismThe National Schism (Ethnikós Dichasmós), also sometimes called The Great Division, was a series of disagreements between King Constantine I and Prime Minister Eleftherios Venizelos regarding the foreign policy of Greece in the period of 1910–1922 of which the tipping point was whether Greece should enter World War I. Venizelos was in support of the Allies and wanted Greece to join the war on their side, while the pro-German King wanted Greece to remain neutral, which would favor the plans of the Central Powers.
Kingdom of ItalyThe Kingdom of Italy (Regno d'Italia, ˈreɲɲo diˈtaːlja) was a state that existed from 17 March 1861, when Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 2 June 1946, when civil discontent led to an institutional referendum to abandon the monarchy and form the modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the Risorgimento. That process was influenced by the Savoy-led Kingdom of Sardinia, which can be considered Italy's legal predecessor state.
