The goal of this work is to analyze nationalist and Neo-fascist organizations established in the territory of Friuli and Venezia-Giulia in the immediate postwar period. These associations, that mainly gathered together former soldier but also common citizens, aimed to defend and legitimate the Italian rights over Friuli Venezia-Giulia region that was still under the Allied control and whose future was uncertain. Among these groups, was not uncommon the presence of ambiguous organizations set up by former members of the Fascist regime formations. Most of these groups acted on their own initiative, but some of them, like the Osoppo Association, were directly linked to the Italian institutions. Therefore, this research pursues the goal of analyzing the protagonists, the organization and propaganda strategies carried out by the different players that were operating in the Italian Eastern border area during the complicated period that followed the Liberation and ended with the Peace Treaty.
