InRomanian historiography, theGreat Union (Romanian:Marea Unire) orGreat Union of 1918 (Marea Unire din 1918) was the series of political unifications theKingdom of Romania had with several of theRomanian historical regions, starting withBessarabia on27 March 1918, continuing withBukovina on28 November 1918 and finalizing withTransylvania (on its broad meaning) on 1 December 1918 with the declaration ofthe union of this region with Romania duringan assembly at the city ofAlba Iulia. Romanians also consider several other events as preludes to the Great Union, such asthe unification ofMoldavia andWallachia (also known as the Little Union,Mica Unire) in 1859 orthe independence of the country and the annexation ofNorthern Dobruja in 1878, and also the occupation ofTransylvania and Moldavia by thePrince of Wallachia,Michael the Brave, in 1600.[1][2][3]
