After the breakup of the Austro-Hungarian Empire after World War I, the 1919 Treaty of Saint-Germain-en-Laye gave Susak and several other territories to the relatively new nation of Italy. The Italian government under the fascist government of Benito Mussolini began the Italianization of these new Italian territories. On Susak, for example, the Italian government changed the spellings and pronunciations of several of the island's surnames. Tarabokija became Tarabocchia; Picinić became Picini. {immigrants from Susak would give Italian as their ethinicity and non Croatian, they themselves would spell Tarabocchia instead of Tarabokija since the Austro-Hungarian government had spent many efforts to reduce the Italian population.
