Transition of the North-Eastern boundary in the 20th Century: The Venezia Giulia's case

The “Venezia Giulia” region, placed at the north eastern Italian border, during the XX century and particularly during the two world wars has been involved in several situations of strong crisis so as to produce significant border variations with territories which, fully or partially, were pertaining to different States. Several population movements occurred, and hereunder we want to recall that one resulting from dismemberment of “Venezia Giulia”, at the end of World War Two.
This dismemberment has caused a significant exodus of Italians from the territories of their historical settling-down: a diaspora that is still a matter of debate about the number of people involved. We studied the phenomenon analysing the “General Census of population speaking different language from Italian resident in the Kingdom of Italy”, of 1939, based on census surveys of 1936.
This recently acquired statistical source was kept secret, as far as the involved number is concerned, until 1998, and it derives from a copy on microfilm stored in the National Archives of Washington.
