|Hymn to October, 1942, Alexander Gerasimov
In 1932, the Soviet state proclaimed that all artists must embrace the Socialist Realist philosophy and style. Its three principles were: partiinost (loyalty to the party), ideinost (correct ideological stance and content), and narodnost (ready accessibility to the people). In 1936, Stalin publicly attacked Dmitry Shostakovich in Pravda for his atonal music. This marked the end of artistic experimentation and the beginning of the purges in the creative unions.
