1) In 1918, through a series of national assemblies, the historical Romanian provinces of Basarabia, Bucovina, and Transylvania voted to unite with Romania, forming a single Romanian state.
2) This unification, known as the Great Union of 1918, fulfilled the centuries-old dream of the Romanian people to live united in one country despite being divided among several states.
3) The Great Union was made possible by Romania's entry into World War I on the side of the Entente and favored by several historical factors, and it led to the establishment of Greater Romania.
