The foreign relations of the Italian Republic are the Italian government's external relations with the outside world. Located in Europe, Italy has been considered a major European power since its unification in 1860. Its main allies are the NATO countries and the EU states, two entities of which Italy is a founding member. Italy was admitted to the United Nations in 1955, and it is a member and a strong supporter of a wide number of international organisations, such as the Organisation for Economic Co-operation and Development (OECD), the General Agreement on Tariffs and Trade and World Trade Organization (GATT and WTO), the Organization for Security and Co-operation in Europe (OSCE), the Council of Europe, and the Central European Initiative.

Its turns in the rotating presidency of international organisations include the Organization for Security and Co-operation in Europe, the G7 and the EU Council. Italy is also a recurrent non-permanent member of the UN Security Council. Italy is an important actor in the Mediterranean region and has close relations with the Romance-speaking countries in Europe and Latin America. Although it is a secular state,Articles 3, 7, 8, 19, 20 of the Constitution of Italy; Constitutional Court's Decision n. 203/1989 Rome hosts the Pope and the headquarters of the Catholic Church, which operates a large diplomatic system of its own. Italy is currently commanding various multinational forces and has significant troops deployed all over the world for peacekeeping missions, and for combating organized crime, illegal drug trade, human trafficking, piracy and terrorism.

History

National unification

The Risorgimento was the era from 1829 to 1871 that saw the emergence of a national consciousness. The Northern Italy monarchy of the House of Savoy in the Kingdom of Sardinia, whose government was led by Camillo Benso, Count of Cavour, had ambitions of establishing a united Italian state. In the context of the 1848 liberal revolutions that swept through Europe, an unsuccessful first war of independence was declared on Austria. In 1855, the Kingdom of Sardinia became an ally of Britain and France in the Crimean War, giving Cavour's diplomacy legitimacy in the eyes of the great powers.Enrico Dal Lago, "Lincoln, Cavour, and National Unification: American Republicanism and Italian Liberal Nationalism in Comparative Perspective." The Journal of the Civil War Era 3#1 (2013): 85–113.William L. Langer, ed., An Encyclopedia of World Cup History. 4th ed. 1968. pp 704–7. The Kingdom of Sardinia again attacked the Austrian Empire in the Second Italian War of Independence of 1859, with the aid of France, resulting in liberating Lombardy. On the basis of the Plombières Agreement, the Kingdom of Sardinia ceded Savoy and Nice to France, an event that caused the Niçard exodus, that was the emigration of a quarter of the Niçard Italians to Italy, and the Niçard Vespers.

In 1860–1861, Giuseppe Garibaldi led the drive for unification in Naples and Sicily conquering the Kingdom of the Two Sicilies (the Expedition of the Thousand),Mack Smith, Denis (1997). Modern Italy; A Political History. Ann Arbor: The University of Michigan Press. while the House of Savoy troops occupied the central territories of the Italian peninsula, except Rome and part of Papal States. This allowed the Sardinian government to declare a united Italian kingdom on 17 March 1861. In 1866, Italy allied with Prussia during the Austro-Prussian War, waging the Third Italian War of Independence which allowed Italy to annex Venetia.

After the Third Italian War of Independence (1866), when the Veneto and Friuli regions were ceded by the Austrians to the newly formed Kingdom Italy, Istria and Dalmatia remained part of the Austro-Hungarian Empire, together with other Italian-speaking areas on the eastern Adriatic. This triggered the gradual rise of Italian irredentism among many Italians in Istria, Kvarner and Dalmatia, who demanded the unification of the Julian March, Kvarner and Dalmatia with Italy. The Italians in Istria, Kvarner and Dalmatia supported the Italian Risorgimento: as a consequence, the Austrians saw the Italians as enemies and favored the Slav communities of Istria, Kvarner and Dalmatia. During the meeting of the Council of Ministers of 12 November 1866, Emperor Franz Joseph I of Austria outlined a wide-ranging project aimed at the Germanization or Slavization of the areas of the empire with an Italian presence:Die Protokolle des Österreichischen Ministerrates 1848/1867.

Finally, in 1870, as France abandoned its garrisons in Rome during the disastrous Franco-Prussian War to keep the large Prussian Army at bay, the Italians rushed to fill the power gap by taking over the Papal States. Italian unification was completed and shortly afterwards Italy's capital was moved to Rome. Later Italy formed the Triple Alliance (1882) with Germany and Austria.

World War I

Even after 1870, after the unification of Italy, many ethnic Italian-speakers (Italians in Trentino-Alto Adige/Südtirol, Savoyard Italians, Corfiot Italians, Niçard Italians, Swiss Italians, Corsican Italians, Maltese Italians, Istrian Italians, and Dalmatian Italians) remained outside the borders of the Kingdom of Italy, planting the seeds of Italian irredentism.

Italy entered into the World War I in 1915 with the aim of completing national unity: for this reason, the Italian intervention in the World War I is also considered the Fourth Italian War of Independence, in a historiographical perspective that identifies in the latter the conclusion of the unification of Italy, whose military actions began during the revolutions of 1848 with the First Italian War of Independence.

Italy defeated the Ottoman Empire in 1911–1912.Charles Stevenson, A Box of Sand: The Italo-Ottoman War 1911–1912: The First Land, Sea and Air War (2014) By 1915, Italy had acquired in Africa a colony on the Red Sea coast (Eritrea), a large protectorate in Somalia and administrative authority in formerly Turkish Libya. Outside of Africa, Italy possessed a small concession in Tientsin in China (following the Boxer Rebellion) and the Dodecanese Islands off the coast of Turkey.

In 1915, Italy abrogated its alliance and declared war on the Austro-Hungarian Empire, leading to bloody conflict mainly on the Isonzo and Piave fronts. Britain, France and Russia had been "keen to bring neutral Italy into World War I on their side. However, Italy drove a hard bargain, demanding extensive territorial concessions once the war had been won". In a deal to bring Italy into the war, under the London Pact, Italy would be allowed to annex not only Italian-speaking Trentino and Trieste, but also German-speaking South Tyrol, Istria (which included large non-Italian communities), and the northern part of Dalmatia including the areas of Zadar (Zara) and Šibenik (Sebenico). Mainly Italian Fiume (present-day Rijeka) was excluded.

In November 1918, after the surrender of Austria-Hungary, Italy occupied militarily Trentino Alto-Adige, the Julian March, Istria, the Kvarner Gulf and Dalmatia, all Austro-Hungarian territories. On the Dalmatian coast, Italy established the first Governorate of Dalmatia, which had the provisional aim of ferrying the territory towards full integration into the Kingdom of Italy, progressively importing national legislation in place of the previous one. The administrative capital was Zara. The Governorate of Dalmatia was evacuated following the Italo-Yugoslav agreements which resulted in the Treaty of Rapallo (1920). After the war, the Treaty of Rapallo between the Kingdom of Serbs, Croats and Slovenes (later the Kingdom of Yugoslavia) and the Kingdom of Italy (12 November 1920), Italy annexed Zadar in Dalmatia and some minor islands, almost all of Istria along with Trieste, excluding the island of Krk, and part of Kastav commune, which mostly went to the Kingdom of Serbs, Croats and Slovenes. By the Treaty of Rome (27 January 1924), the Free State of Fiume (Rijeka) was divided between Italy and Yugoslavia. Also, Italy occupied southern Albania and established a protectorate over Albania, which remained in place until 1920.Nigel Thomas. Armies in the Balkans 1914–18. Osprey Publishing, 2001, p. 17.

The Allies defeated the Austrian Empire in 1918 and Italy became one of the main winners of the war. At the Paris Peace Conference in 1919, Prime Minister Vittorio Emanuele Orlando focused almost exclusively on territorial gains, but he got far less than he wanted, and Italians were bitterly resentful when they were denied control of the city of Fiume. The conference, under the control of Britain, France and the United States refused to assign Dalmatia and Albania to Italy as had been promised in the Treaty of London. Britain, France and Japan divided the German overseas colonies into mandates of their own, excluding Italy. Italy also gained no territory from the breakup of the Ottoman Empire.

Italy did not receive other territories promised by the Treaty of London, so this outcome was denounced as a Mutilated victory. The rhetoric of Mutilated victory was adopted by Benito Mussolini and led to the rise of Italian fascism, becoming a key point in the propaganda of Fascist Italy. Historians regard Mutilated victory as a "political myth", used by fascists to fuel Italian imperialism and obscure the successes of liberal Italy in the aftermath of World War I.G.Sabbatucci, La vittoria mutilata, in AA.VV., Miti e storia dell'Italia unita, Il Mulino, Bologna 1999, pp.101–106 Italy also gained a permanent seat in the League of Nations's executive council.
