Vincenzo Marcon (known as “Davilla”) was a communist militant, born in Trieste, who
led the PCd’I (Partito Comunista d’Italia) Julian “federation” between 1942 and 1943.
That year, he was dismissed by the new direction of that organisation, gathered around Luigi Frausin, who replaced Marcon’s line (focused on a strong collaboration with the Slovenian partisan movement) with another one based on the unity of the Italian antifascist parties and movements following the politics of the Committees of National Liberation. Thanks to the analysis of the documentation produced by the Italian political police and the Italian and Slovenian communist movements, this article provides the first scientific analysis of Marcon’s role in the communist ranks in the Upper-Adriatic Littoral during the “partisan war”.
