The national day of Romania also called the Union Day or the Unification Day was set after the 1989 Romanian Revolution, when the communist regime came to an end. On this day all Romanians all over the world celebrate the unification of Transylvania (the central region of Romania, where Dracula’s castle is)—which had been under Austro-Hungarian Empire—with Romania. The union of Transylvania with Romania in 1918 was the last event which marked the unification of the country. A few days before that date, three other Romanian regions became part of Romania, after being under different occupations: Banat (Austro-Hungarian occupation), Bessarabia (Russian occupation), and Bukovina (Austro-Hungarian occupation).
