History of the Italian Republic through a referendum. In April 1945, the Allies of World War II advanced in the Po plain supported by the Italian resistance movement, and defeated the fascist Italian Social Republic, a puppet state instituted by Nazi Germany and headed by Benito Mussolini. Mussolini was killed by resistance fighters in April 1945. Victor Emmanuel formally abdicated on 9 May 1946; his son became king as Umberto II of Italy. A Constitutional Referendum was held on 2 June 1946. Republicans won, and the monarchy was abolished. The Kingdom of Italy was no more. The House of Savoy, the Italian royal family, was
King of the Romanians Romania. The kingdom of Romania was a constitutional monarchy for most of its existence with the exception of 1938–1944, during the dictatorships of Carol II (1938–1940) and Ion Antonescu (1940–1944). On 23 August 1944, Michael I restored the last democratic royal Constitution of 1923. However, during his second reign (1940–1947), Michael I reigned mostly as an extraconstitutional king, without a parliamentary vote. Parliament was initially suspended and reinstated only later, in 1946. Michael I was crowned and anointed by the Orthodox Patriarch, Nicodim Munteanu, in the Patriarchal Cathedral of Bucharest, on the day of his second accession, 6 September 1940.
