Question: Of what nationality are both Maria and Ion Antonescu?
Context: King Michael's Coup was a "coup d'état" led by King Michael I of Romania during World War II on 23 August 1944.  The king removed the government of Ion Antonescu, which had aligned Romania with Nazi Germany, after the Axis front in northeastern Romania collapsed in the face of a successful Soviet offensive. A referendum on the policies of Ion Antonescu was held in Romania on 9 November 1941.  The referendum, the second that year on Antonescu's policies, were held after the extension of working hours on 2 October had been met with riots.  The vote was carried out orally, with a silence taken as a "yes" vote, and was approved with 99.99% in favour. The Iași pogrom or Jassy pogrom (pronounced:"Yash") of 29 June 1941 was a series of pogroms launched by governmental forces under Ion Antonescu in the Romanian city of Iaşi (Jassy) against its Jewish population, resulting in the murder of at least 13,266 Jews, according to Romanian authorities. Maria Antonescu (born Maria Niculescu, also known as Maria General Antonescu, later Maria Mareșal Antonescu, or Rica Antonescu; November 3, 1892 – October 18, 1964) was a Romanian socialite and philanthropist, the wife of World War II authoritarian Prime Minister and "Conducător" Ion Antonescu.  A long-time resident of France, she was twice married before her wedding to Antonescu, and became especially known for her leadership of charitable organization grouped in the Social Works Patronage Council organization, having Veturia Goga for her main collaborator.  The Council profited significantly from antisemitic policies targeting Romanian Jews, and especially from the deportation of Bessarabian Jews into Transnistria, taking over several hundred million lei resulting from arbitrary confiscations and extortion. The Wiesel Commission is the International Commission on the Holocaust in Romania, which was established by former President Ion Iliescu in October 2003 to research and create a report on the actual history of the Holocaust in Romania and make specific recommendations for educating the public on the issue.  The Commission, which was led by Nobel Peace Prize laureate Elie Wiesel as well as Jean Ancel, released its report in late 2004.  The Romanian government recognized the report's findings and acknowledged the deliberate participation in the Holocaust by the World War II Romanian regime led by Ion Antonescu.  The report assessed that between 280,000 and 380,000 Jews were murdered or died under the supervision and as a result of the deliberate policies of Romanian civilian and military authorities.  Over 11,000 Romani were also killed.  The Wiesel Commission report also documented pervasive antisemitism and violence against Jews in Romania before World War II, when Romania's Jewish population was among the largest in Europe. Mihai Robu (April 10, 1884—September 27, 1944) was a Romanian cleric, bishop of the Roman Catholic Diocese of Iaşi.  Born in Săbăoani, Neamţ County, He entered the Roman Catholic Theological Institute of Iași in 1894, being ordained deacon in 1906 and priest in 1907.  For several years, starting before his priestly ordination, he was in charge of the Iaşi seminarians.  During World War I, when the seminary was closed, he was a parish priest at Văleni, Faraoani and Bacău.  In 1920, he returned to teach when the seminary reopened, and was named secretary to Bishop Alexandru Cisar.  In 1922, he was named parish priest at Horlești and chaplain at an Iaşi monastery.  In 1925, he was consecrated Bishop of Iaşi by Cisar.  Among his activities were the building of numerous churches, special attention to the seminary and the opening of a new one at Luizi-Călugăra, support for the Catholic press and many visits to parishes in the diocese.  By 1943, during World War II, Robu had become disturbed by the treatment Moldavian Catholics were receiving from local officials who derided and harassed them as allegedly being ethnic Hungarians or Csangos.  He sent a petition to dictator Ion Antonescu in which he explained that the community were in fact ethnic Romanians, and asked that the mistreatment come to an end.  The government agreed with Robu, promising to investigate and punish those responsible.  In March 1944, due to the approach of the Eastern Front, he closed the seminary and withdrew with the students to Beiuş.  Meeting with repression from the German and Hungarian armies, he went to the mountains at Finiș in mid-September.  He caught double pneumonia and soon died.  Buried in Beiuş, his remains were moved to the old Roman Catholic cathedral in Iaşi in 1964. A referendum on the policies of Ion Antonescu was held in Romania on 5 March 1941.  Under pressure from Nazi Germany, King Carol II had appointed Antonescu as Conducător on 6 September 1940.  Voting was done orally, with voters answering yes or no.  Silence was taken to be a "yes".  The referendum was approved by 99.9% of voters.  A second referendum on Antonescu's policies was held in November. Radu D. Lecca (February 15, 1890–1980) was a Romanian spy, journalist, civil servant and convicted war criminal.  A World War I veteran who served a prison term for espionage in France during the early 1930s, he was a noted supporter of antisemitic concepts and, after 1933, an agent of influence for Nazi Germany.  While becoming a double agent for Romania's Special Intelligence Service (SSI), Lecca was involved in fascist politics, gained in importance during World War II and the successive dictatorships, and eventually grew close to "Conducător" Ion Antonescu. Ion Victor Antonescu (] ; June 15, 1882 – June 1, 1946) was a Romanian soldier and authoritarian politician who, as the Prime Minister and "Conducător" during most of World War II, presided over two successive wartime dictatorships.  After the war, he was convicted of war crimes and executed. The Socialist Peasants' Party (Romanian: "Partidul Socialist Țărănesc", or "Partidul Socialist Țărănist", PSȚ) was a short-lived political party in Romania, presided over by the academic Mihai Ralea.  Created nominally in 1938 but dissolved soon after, it reemerged during World War II.  A clandestine group, it opposed the fascist regime of Ion Antonescu, although its own roots were planted in authoritarian politics.  Looking to the Soviet Union for inspiration, the PSȚ was cultivated by the Romanian Communist Party (PCdR), and comprised a faction of radicalized social democrats, under Lothar Rădăceanu.
