Union of Transylvania with Romania was declared on December 1 [O.S. November 18] 1918 by the assembly of the delegates of ethnic Romanians held in Alba Iulia.
The national holiday of Romania, the Great Union Day (also called Unification Day[1]) occurring on December 1, commemorates this event. The holiday was set after the 1989 Romanian Revolution, and marks the unification not only of Transylvania, but also of the provinces of Banat, Bessarabia and Bukovina with the Romanian Kingdom, in 1918, the Union of Transylvania with Romania being the last event, sealing the unification of the country.
