Soviet art is the visual art style produced after the Russian Revolution of 1917 and during the existence of the Soviet Union, until its collapse in 1991. The Russian Revolution led to an artistic and cultural shift within Russia and the Soviet Union as a whole, including a new focus on socialist realism in officially approved art.
