The arrival of Fascism in Italy and Nazism in Germany brought forth a new state of mind in Europe in the late 1930s. The atmosphere was one of war and growing unrest followed by an increased number of armed conflicts. In today’s Croatia, it was in Istria that Fascism first laid its roots, despite the existence of occasional and spontaneous forms of resistance. When the German occupant came to Croatia in 1941 and NDH was established (in reality just a marionette for Hitler’s Nazi policy), serious forms of resistance and antifascism started taking shape. This antifascism fight during the war, as for Croatia but also for the entire world, represented the best and only answer and form of retaliation towards such a cruel, violent and unjust regime that was at the heart of Nazi-Fascism, which managed to poison the majority, if not the entirety of the world. Academic literature and articles, along with Internet sources related to the topic were all used for the purpose of writing this thesis
