This thesis deals with the cultural efforts of the Swedish labour movement during the periodof 1917-1939. It aims to examine the similarities and differences between social democratsand communists in their approach towards culture.My theoretical guidelines are the dialectic and materialistic view on history as set forth byKarl Marx and Friedrich Engels.I have examined some important individuals in the cultural debate within the Swedish labourmovement, such as Ture Nerman and Arthur Engberg, and I also briefly outline the debate inthe Soviet Union from the classics of Lenin and Stalin.I have found that the social democrats were mainly concerned with a democratic distributionof the existing bourgeois culture rather than working for the creation of a new proletarianculture; the communists on the other hand made considerable efforts to benefit the workers'own culture based on class struggle, but failed to threaten the social democratic ideologicalhegemony among the Swedish working class.
