A form of modern realism imposed in Russia by Stalin following his rise to power after the death of Lenin in 1924. The doctrine was formally proclaimed by Maxim Gorky at the Soviet Writers Congress of 1934, although not precisely defined. In practice, in painting it meant using realist styles to create rigorously optimistic pictures of Soviet life. Any pessimistic or critical element was banned, and this is the crucial difference from social realism. It was quite simply propaganda art, and has an ironic resemblance to the Fascist realism imposed by Hitler in Germany (see Entartete Kunst). Outside the Soviet Union, socialist artists produced much freer interpretations of the genre.
