Miroslav Krleža adhered to the idea od Social Democracy rather early but after the crash of the Second Internacional he abandoned the idea of creating a classless society peacefully, and thrilled by the October Revolution in Russia, he declared himself a Bolshevik and started advocating Socialist Revolution. He became a member of the Communist Party of Yugoslavia (KPJ). Having been socialistically oriented, he criticized the Kingdom of SHS, regime of Great Serbia and prevailing unitarianism. He advocated political conception of federalism, as well as autonomy and artistic creation while criticizing Stalinist dictatorship in the Soviet Union which led to conflict with the radicals in the KPJ who proclaimed the aesthetics of social realism. All of this, as well as difference of opinion between Krleža and others on the political left, led to conflict of the literary left. During the Second World War Krleža was in Zagreb but he refused to join the Partisans justifying himself with fear for his own life. Right after the War, as the political circumstances changed with "Resolution on the situation in the KPJ", Krleža became programmer and director of cultural and scientific initiatives under protection of Josip Broz Tito. Krleža was in charge of the Yugoslavian exhibition, which was based on his theory of convergent development of Yugoslavian peoples through the history, at the Exhibition of Medievel Art in Paris in 1950. He postulated concepts of the rebellious consciousness m, the philosophy of resistance and permanent aspiration to consolidation which culminated in People's Liberation Struggle as a synthesis.
