Umberto II (Italian: Umberto Nicola Tommaso Giovanni Maria di Savoia; 15 September 1904Â â 18 March 1983) was the last king of Italy. Umberto's reign lasted for 34 days, from 9 May 1946 until his formal deposition on 12 June 1946, although he had been the de facto head of state since 1944. Due to his short reign, he was nicknamed the May King (Italian: Re di maggio).
Umberto was the third child and only son among the five children of Victor Emmanuel III and Elena of Montenegro. As heir apparent to the throne, he received a customary military education and pursued a military career afterwards. In 1940, he commanded an army group during the brief Italian invasion of France shortly before the French capitulation. In 1942, he was promoted to Marshal of Italy but was otherwise inactive as an army commander during much of World War II. Umberto turned against the war following Italian defeats at Stalingrad and El Alamein, and tacitly supported the ouster of Benito Mussolini.
