What do Romanians celebrate on their December 1st National Day?
The short answer is 'unification and freedom', and the theme is probably a common one among many other countries in the world.
For Romanians, December 1st is the Great Union Day. On this day in 1918, during the reign of king Ferdinand I, Romania made of Moldova and Wallachia at the time – was united with Transylvania, Crisana, Banat and the Maramures area.
The unification happened in Alba Iulia, were the unification declaration was read during a public event, attended by over 100,000 Romanians. The declaration was read by Vasile Goldis, Romanian academician and politician.
Romania of that time also included the Republic of Moldova (Basarabia), Banat and the Cadrilater area, which are no longer part of today's Romania. In 1918, with this unification, Romania almost doubled its territory.
Later on in 1940, Romania lost Basarabia and Bucovina in 1940, after the Molotov-Ribentrop pact, the two regions being annexed to the Soviet Republic. The north of Transylvania went to Hungary, while the south of Dobrogea (the Cadrilater area) went to Bulgaria.
