Military History of Italy - World War I

World War I

For more details on this topic, see Italy in World War I.

In spite of its official status as member of the Triple Alliance together with Germany and Austria-Hungary, in the years before the outbreak of the conflict the Italian government had enhanced its diplomatic efforts towards United Kingdom and France. This was because the Italian government had grown convinced that a support of Austria (which had been also the traditional enemy of Italy during the 19th century Risorgimento) would not grant to Italy the Italian-speaking lands the country was aiming for in its territorial expansion: Trieste, Istria, Zara and Dalmatia, all Austrian possessions. In fact, a secret agreement signed with France in 1902 practically nullified Italy's membership in the Triple Alliance.

A few days after the outbreak of the conflict, on 3 August 1914, the government, led by the conservative Antonio Salandra, declared that Italy would not commit its troops, maintaining that the Triple Alliance had only a defensive stance, whereas Austria-Hungary had been the aggressor. In reality, both Salandra and the minister of Foreign Affairs, Sidney Sonnino, started diplomatic activities to probe which side was ready to grant the best reward for Italy's entrance in the war. Although the majority of the cabinet (including former Prime Minister Giovanni Giolitti) was firmly contrary to the intervention, numerous intellectuals, including socialists such as Ivanoe Bonomi, Leonida Bissolati and Benito Mussolini, declared in favour of the intervention, which was then mostly supported by the Nationalist and the Liberal parties.

The diplomatic moves led to the London Pact (26 April 1915), signed by Sonnino without the approval of the Italian Parliament. By the Pact, in case of victory Italy was to be given Trentino and the South Tyrol up to the Brenner Pass, the entire Austrian Littoral (with Trieste, Gorizia-Gradisca and Istria, but without Fiume), parts of western Carniola (Idrija and Ilirska Bistrica) and north-western Dalmatia with Zadar and most of the islands, but without Split. Other agreements concerned the sovereignty of the port of Valona, the province of Antalya in Turkey and part of the German colonies in Africa.

Germany and Austria-Hungary had only advanced the possibility of negotiating parts of the Trentino and Eastern Friuli, without Gorizia and Trieste. The offer of the French colony of Tunisia was deemed unsatisfactory.

In April 1915 Italy joined the Entente and on 3 May 1915 officially rejected the Triple Alliance. In the following days Giolitti and the neutralist majority of the Parliament fought to keep Italy out of the conflict, while the nationalists demonstrated in the squares in favour of entrance into the war (the nationalist poet Gabriele D'Annunzio defined them le radiose giornate di Maggio - "the sunny days of May"). On 13 May Salandra presented his resignation to King Victor Emmanuel III. Giolitti, fearful of a further blow to governing institutions, declined to succeed as prime minister and also resigned. Italy thenceforth entered the war under the impetus of a relative minority of its population and politicians.
