I know these two were not Royalty per se, but they sure ACTED like they were. They ran Romania between them, gave important government positions to family and friends, and their three children acted like spoiled Princes and a Princess (they had one daughter, two sons). Furthermore, when Nicolae died, his oldest son, Nico, was to take over (much like Kim Jong Il took over from his old man, Kim Il Sung in North Korea). This was not a Communist leader, this was a despotic king and his queen.
Unfortunately, the Ceausescu's showed the WORST of Royalty the way they ran the country. It was "Love us, or die." Ceausescu called himself fancy names like "Genius Of The Carpathians" while Elena presented herself as a brilliant scientist (despite the fact that she flunked out of high school). Of course, when you're co-ruler of a country, you can have as many doctorates as you want, because of ghost written papers.
They lived in fancy houses, droves fancy cars, and wanted for nothing. All this while their people starved. They were building this big super palace in Bucharest when the Revolution of 1989 came. When I heard they were executed, I felt no sympathy. They died fast, unlike many of their victims. I believe that had they just given up, like the other Communist leaders of Eastern Europe did in 1989, they might not have been executed (although they might have received prison sentences). However, when they ordered the military to fire on the crowds, that was it. When the military switched sides, it was game over.
So while these two were not officially royal autocrats, they sure played the part well, didn't they.
