when did italy enter the first world war
Military history of Italy during World War I On 3 May 1915 Italy officially revoked the Triple Alliance. In the following days Giolitti and the neutralist majority of the Parliament opposed declaring war, while nationalist crowds demonstrated in public areas for it. (The nationalist poet Gabriele D'Annunzio called this period le radiose giornate di Maggioâ€”"the sunny days of May"). Giolitti had the support of the majority of Italian parliament so on 13 May Salandra offered his resignation to King Victor Emmanuel III, but then Giolitti learned that the London Pact was already signed: fearful of a conflict between the Crown and the Parliament and the consequences on both internal stability and foreign relationships, Giolitti accepted the fait accompli, declined to succeed as prime minister and Salandra's resignation was not accepted. On 23 May, Italy declared war on Austria-Hungary. This was followed by declarations of war on the Ottoman Empire (21 August 1915[1], following an ultimatum of 3 August), Bulgaria (19 October 1915) and the German Empire (28 August 1916).[2]
