King Victor Emmanuel III of Italy abdicates and is succeeded by Umberto II.

Victor Emmanuel III was King of Italy from 29 July 1900 until his abdication on 9 May 1946. A member of the House of Savoy, he also reigned as Emperor of Ethiopia from 1936 to 1941 and King of the Albanians from 1939 to 1943, following the Italian invasions of Ethiopia and Albania. During his reign of nearly 46 years, which began after the assassination of his father Umberto I, the Kingdom of Italy became involved in two world wars. His reign also encompassed the birth, rise, and fall of the Fascist regime.

Umberto II 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.
