The foundations of socialist North Korean literature were laid in the period between 1945 and 1960s, when North Korea adopted many Soviet-style forms of organization. Along with them, restrictions and political imperatives found their way to literature. Immediately after the liberation, North Korea followed in the footsteps of Soviet literature. But by the de-Stalinization of the mid-1950s in the Soviet Union, the relationship changed. Kim Il-sung saw the moment as an opportunity to lessen the control of the Soviets and increase his own. He accomplished this by denouncing all things "foreign" in literature in a speech entitled "On Eliminating Dogmatism and Formalism and Establishing "Juche" in Ideological Work". From there on, North Korean literature would have a nationalistic outlook, but Soviet elements introduced during the 1940s would remain steadfast.
