The contribution focuses on the perception and presentation of the October Revolution’s significance in the circle of Slovenian communists between 1920 and 1945. It is based especially on the contemporaneous mainstream and underground press, published by the Communist Party and at least partly available to a wider circle of readers. The analysis of the materials reveals an extremely affirmative attitude towards the October Revolution, since the Slovenian communists, as a part of the Yugoslav Communist Party and the international communist movement under the auspices of the Comintern, deemed it to be the most important watershed in the human history. At every anniversary of the Revolution, the Slovenian communists would repeatedly emphasise the fundamental principles that had enabled the victorious triumph of the Revolution under the leadership of the Bolshevik Party as well as the subsequent implementation of socialism in the Soviet Union. During the period between both world wars, the Slovenian communists would particularly underline the progress in the economic, cultural and social field; while during World War II they kept emphasising the power of the Soviet state and its Red Army, which was capable of confronting Hitler and whose power was also based on the October’s “accomplishments”.
