Unification of Moldova and Romania
The unification of Moldova and Romania is the idea that Moldova and Romania should become a single sovereign state and the political movement which seeks to bring it about. Beginning during the Revolutions of 1989 (including the Romanian Revolution and the independence of Moldova from the Soviet Union), the movement's basis is in the cultural similarity of the two countries, both being Romanian-speaking, and their history of unity as part of Greater Romania.
