Question: Who was the last monarch to reign in Romania, from 20 July 1927 to 8 June 1930 and again from 6 September 1940 until his abdication on 30 December 1947?
Context: Victory Nunatak ( ) is a conspicuous island-like nunatak with three rocky summits, the southernmost and highest rising to 360 meters.  It rises above the ice of southeastern Mobiloil Inlet 8 nautical miles (15 km) southeast of Kay Nunatak on the east coast of Antarctic Peninsula.  The nunatak was first mapped by W.L.G. Joerg from air photos taken by Lincoln Ellsworth on November 23, 1935.  It was subsequently photographed from the air by United States Antarctic Service (USAS) in September 1940, the Falkland Islands Dependencies Survey (FIDS) in August 1947, and the Ronne Antarctic Research Expedition (RARE) (Trimetrogon air photography) in December 1947.  It was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1961; when viewed from the air three dots and a dash, Morse code for the letter "V", are apparent on the surface of the feature. The Kingdom of Romania (Romanian: "Regatul României" ) was a constitutional monarchy which existed between 13 March 1881 and 30 December 1947, specified by the first three Constitutions of Romania (1866, 1923, 1938).  The Kingdom of Romania began with the reign of King Carol I of Romania who gained Romanians' independence from the Ottoman Empire in the Romanian War of Independence (part of the Russo-Turkish War of 1877-1878), and ended with the abdication of King Michael I of Romania on 30 December 1947, imposed by the Soviet Union with the tacit and secret, implicit consent of its allies (as a result of the Yalta Conference and secret agreements).  As such, it is quite distinct from the Romanian Old Kingdom, which refers strictly to the reign of King Carol I of Romania, between 14 March (O.S.) 1881 and 27 September (O.S.) 1914. Victor Emmanuel III (Italian: "Vittorio Emanuele III" , Albanian: "Viktor Emanueli III" ; 11 November 1869 – 28 December 1947) was the King of Italy from 29 July 1900 until his abdication on 9 May 1946.  In addition, he claimed the thrones of Ethiopia and Albania as Emperor of Ethiopia (1936–41) and King of the Albanians (1939–43), claims not recognised by the other great powers.  During his long reign (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 Italian Fascism. No. 8 Elementary Flying Training School (No. 8 EFTS) was a Royal Australian Air Force (RAAF) pilot training unit that operated during World War II.  It was one of twelve elementary flying training schools employed by the RAAF to provide introductory flight instruction to new pilots as part of Australia's contribution to the Empire Air Training Scheme.  No. 8 EFTS was established in September 1940 at Narrandera, New South Wales.  Training ceased in December 1944 and the school was reduced to maintaining base infrastructure and aircraft.  It was officially disbanded in June 1945 and renamed Care and Maintenance Unit (CMU) Narrandera.  The CMU was disbanded in December 1947. Michael I (Romanian: "Mihai I" ] ; born 25 October 1921) reigned as King of Romania, from 20 July 1927 to 8 June 1930 and again from 6 September 1940 until his abdication on 30 December 1947. Ferdinand I (Ferdinand Viktor Albert Meinrad; 24 August 1865 – 20 July 1927), nicknamed "Întregitorul" ("the Unifier"), was King of Romania from 10 October 1914 until his death in 1927. The succession order to the throne of the Romanian monarchy, abolished since 1947, was regulated by the monarchical constitution of 1923 and the 1884 Law of the Romanian Royal House Rules enacted pursuant to the 1866 Constitution of Romania which had confirmed the enthronement of Prince Karl (Carol) of Hohenzollern-Sigmaringen.  The defunct 1923 Constitution stipulated Salic law, according to which the throne was hereditary in King Carol I's legitimate descent and, if his male issue failed, in the descent of his brothers of the Sigmaringen princely branch of the House of Hohenzollern, according to agnatic primogeniture and to the perpetual exclusion of females and their descendants.  The last monarch to reign in Romania was King Michael I, who was born in 1921, abdicated his throne on 30 December 1947 under coercion, and went into exile in Switzerland. The Blitz was a German bombing offensive against Britain in 1940 and 1941, during the Second World War.  The term was first used by the British press as an abbreviation of "Blitzkrieg" (lightning war).  The Germans conducted mass air attacks against industrial targets, towns and cities, beginning with raids on London towards the end of the Battle of Britain in 1940, a battle for daylight air superiority between the "Luftwaffe" and the Royal Air Force over the United Kingdom.  By September 1940, the "Luftwaffe" had failed and the German air fleets ("Luftflotten") were ordered to attack London, to draw RAF Fighter Command into a battle of annihilation.  Adolf Hitler and "Reichsmarschall" Hermann Göring, commander-in-chief of the "Luftwaffe", ordered the new policy on 6 September 1940.  From 7 September 1940, London was systematically bombed by the "Luftwaffe" for 56 out of the following 57 days and nights.  Most notable was a large daylight attack against London on 15 September. Carol II (15 October 18934 April 1953) reigned as King of Romania from 8 June 1930 until his enforced abdication on 6 September 1940. Ernest Urdăreanu (1897–1985) was the Minister of the Court during the reign of King Carol II of Romania (1930–1940).  As closest confidant of the King Urdăreanu was, alongside Madame Lupescu, the King’s mistress, the third member of the triumvirate which held virtually all power in the state during the thirties of the last century.  It is alleged that he was, after the King, the most powerful and the most hated man in Romania.  Following the abdication of the King in 1940, Urdăreanu left the country together with him and Madame Lupescu to seek asylum and he stayed with them for the rest of his life.
