Romanian Great Union Day

Romanian Great Union Day is observed every year on December 1. It is the national holiday of Romania, celebrating the unification of several historical Romanian provinces into a single modern state — a milestone that shaped the country as it is today.

History of Romanian Great Union Day

On December 1, 1918 the Great National Assembly of Alba Iulia declared the union of Transylvania (alongside Banat, Crișana, Maramureș) with the Kingdom of Romania, a historic act that completed the formation of Greater Romania.
Although earlier Romanian national holidays fell on other dates (for example May 10 — marking independence from the Ottoman Empire), after the fall of the communist regime in 1990 December 1 was officially adopted as the country’s National Day.
