"In Transylvania the National Assembly called at Alba Iulia on November18/December 1, 1918 voted, within the presence of over 100,000 delegates, to unite Transylvania and Banat with Romania.
The international peace treaties of 1919-1920 signed at Neuilly,Saint-Germain, Trianon and Paris, established the new European realities and also sanctioned the union of the provinces that were inhabited by Romanians into one single state (295,042 square kilometers, with a population of 15.5million)."
