Mihály I (in Romanian Mihai I al României, Szinaja, October 25, 1921 – Aubonne(wd), December 5, 2017) II. Son of King Charles of Romania and Princess Ilona of Greece and Denmark, grandson of King Ferdinand I of Romania, King of Romania from 1927 to 1930 and from 1940 to 1947. He was born in the city of Sinaja in 1921. He was already the official ruler of the country at the age of six after his grandfather, Ferdinand I, died, and his father, Prince Charles, abdicated the Romanian throne and left the country. Since he was still a minor in 1927, regents ruled in his place. Due to the parliament's dissatisfaction with the regency system, II. Károly returned to the country in 1930 and replaced Mihály on the throne, at the same time making him the number one candidate for the throne and appointing him Grand Voyeur of Gyulafehérvár. In 1940, Ion Antonescu carried out a coup, and the new government put the 18-year-old Mihály on the throne without the consent of the parliament. The power of the new king was very limited, although he officially held a number of ranks and titles, the country was governed by the fascist party leader, Ion Antonescu. In 1944, while the Soviet troops were approaching the Romanian border, Mihály began to cultivate closer and closer relations with the allied powers, so much so that he took back power on August 23, 1944, arrested Antonescu and handed him over to the Romanian communists. The country sided with the Allies, concluding an armistice with them and officially entering the war against Germany, but Soviet troops nevertheless soon invaded the country. In June 1948, he married Princess Anna de Bourbon-Parma, with whom he had five daughters. 1947. on December 30, the Romanian communists called on him to leave the throne and announced the end of the kingdom and the establishment of the People's Republic. After a few days, he resigned, and on January 3, 1948, he was expelled from the country along with many members of the royal family. He was stripped of his citizenship that same year.

1927-1930: Mihály came to the throne at the age of six, after his grandfather, Ferdinand I, died, and his father, II. Károly resigned. Three regents exercised power instead of the king. During this period, the Romanian mint produced coins with the previous royal coats of arms and portraits, but instead of the king's name, the inscription "Regatul României" (Romanian Kingdom) was used. The coins were made of silver, bronze, nickel and aluminum. The largest denomination was 5 lei. 1930-1940: II. Károly returned to the country and took back the throne from Mihály. The coinage again used the king's portrait and coat of arms, as well as the inscription "Carol II Regele României" (Carol II King of Romania). The material of the coins remained the same, but the denominations increased. The largest denomination was 100 lei. 1940-1947: Ion Antonescu staged a coup and put Mihály on the throne. However, the king's power was limited and the country became an ally of Nazi Germany. The coinage still used the king's portrait and coat of arms, but the inscription "Mihai I Regele României" (Mihály I King of Romania). The material of the coins changed, due to the war there was a metal shortage. The coins were made of aluminum, iron, zinc, copper and nickel. The largest denomination was 20 lei. In 1944, King Mihály sided with the Allies and arrested Antonescu. After the war, the Communist Party grew stronger and forced the king to resign in 1947. This marked the end of the Romanian kingdom and coinage.
