This biographical and cultural-historical study focuses on the life of the Carinthian ironworker Ivan Ditinger, who in the 1920s was one of the first and closest collaborators of Lovro Kuhar - Prežihov Voranec in the party cell in Guštanj until the writer’s emigration in 1930. Ditinger learned about communism in the spring of 1919 from Kuhar, who was ten years younger than him, and both are among the first Slovenian communists. Their commitment to the problems of social disadvantage of the peasantry and the working class, which were not solved by the time after the end of the First World War, due to the specific social and national situation of both actors on the new Austrian-Yugoslav border (1920), convincingly describes and explains the reasons for the mass zeal for communism of the young and middle generation in the next two decades until the Second World War.
