(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).

Document 10: Military history of Italy during World War II: However Italy's conquests were always heavily contested, both by various insurgencies (most prominently the Greek resistance and Yugoslav partisans) and Allied military forces, which waged the Battle of the Mediterranean throughout and beyond Italy's participation. Ultimately the Italian empire collapsed after disastrous defeats in the Eastern European and North African campaigns. In July 1943, following the Allied invasion of Sicily, Benito Mussolini was arrested by order of King Victor Emmanuel III, provoking a civil war. Italy's military outside of the peninsula itself collapsed, its occupied and annexed territories falling under German control. Italy surrendered to the Allies at the end of the Italian Campaign.

Document 14: Yale University: Between 1925 and 1940, philanthropic foundations, especially ones connected with the Rockefellers, contributed about $7 million to support the Yale Institute of Human Relations and the affiliated Yerkes Laboratories of Primate Biology. The money went toward behavioral science research, which was supported by foundation officers who aimed to "improve mankind" under an informal, loosely defined human engineering effort. The behavioral scientists at Yale, led by President James R. Angell and psychobiologist Robert M. Yerkes, tapped into foundation largesse by crafting research programs aimed to investigate, then suggest, ways to control, sexual and social behavior. For example, Yerkes analyzed chimpanzee sexual behavior in hopes of illuminating the evolutionary underpinnings of human development and providing information that could ameliorate dysfunction. Ultimately, the behavioral-science results disappointed foundation officers, who shifted their human-engineering funds toward biological sciences.
Document 15: Military history of Italy during World War II: The participation of Italy in the Second World War was characterized by a complex framework of ideology, politics, and diplomacy, while its military actions were often heavily influenced by external factors. The imperial ambitions of the Fascist regime, which aspired to restore the Roman Empire in North Africa and the Mediterranean (the Mare Nostrum, or the Italian Empire), were partially met with the annexation of Albania and the Province of Ljubljana, and the occupation of British Somaliland and other territories, but ultimately collapsed after defeats in the East and North African campaigns. In July 1943, following the Allied invasion of Sicily, Benito Mussolini was arrested by order of King Victor Emmanuel III, provoking a civil war. Italy surrendered to the Allies at the end of the Italian Campaign. The northern half of the country was occupied by Germans with the fascists help and made a collaborationist puppet state (with more than 600,000 soldiers), while the south was governed by monarchist and liberal forces, which fought for the Allied cause as the Italian Co-Belligerent Army (at its height numbering more than 50,000 men), helped by circa 350,000 partisans of disparate political ideologies that operated all over Italy.
