Socialist realism became state policy in 1934 when the First Congress of Soviet Writers met and Stalin's representative Andrei Zhdanov gave a speech strongly endorsing it as "the official style of Soviet culture". It was enforced ruthlessly in all spheres of artistic endeavour. Form and content were often limited, with erotic, religious, abstract, surrealist, and expressionist art being forbidden. Formal experiments, including internal dialogue, stream of consciousness, nonsense, free-form association, and cut-up were also disallowed. This was either because they were "decadent", unintelligible to the proletariat, or counter-revolutionary.
