Regele Mihai la Bucuresti de Paste Aprilie 1992

"He was again proclaimed king in September 1940, at the age of 19, and reigned until December 30, 1947, when the communists forced him to abdicate and leave the country. One year later, the communist regime stripped him of his Romanian citizenship...

...The king’s exile, however, didn’t end in December 1989, when the communist regime in Romania was overthrown through a bloody revolution. The new regime led by former Communist Party member Ion Iliescu, didn’t allow King Michael to return and it was only in 1997 that the king got back his Romanian citizenship and the right to return to the country...

...The king was first allowed to return to Romania in the spring of 1992, on Easter. Over one million people reportedly gathered in Bucharest to see him. This alarmed the regime of president Ion Iliescu, which didn’t allow the king to return to Romania for several years. In 1994, King Michael flew to Otopeni Airport but was not allowed to enter the country."
