Question: When did Italy join the same conflict as Albert I of the country that held the 1920 Summer Olympics which the country polkagris comes from also participated?

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 Maggio -- ``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, following an ultimatum of 3 August), Bulgaria (19 October 1915) and the German Empire (28 August 1916). <SEP> herman carel felix clotilde von heijden (11 april 1890 in weerselo – 17 november 1982 in boxtel) was a football (soccer) player from the netherlands, who represented his home country at the 1920 summer olympics. there he won the bronze medal with the netherlands national football team. he was also present at the 1912 summer olympics although he did not play and therefore received no medal. later he became mayor of rosmalen, north brabant (1923–1955). <SEP> 260 competitors, 247 men and 13 women, took part in 100 events in 18 sports.
