In page Kazimir Malevich:

"

In autumn 1930, he was arrested and interrogated by the OGPU in Leningrad, accused of Polish espionage, and threatened with execution. He was released from imprisonment in early December.[1][2] Critics derided Malevich's art as a negation of everything good and pure: love of life and love of nature. The Westernizer artist and art historian Alexandre Benois was one such critic. Malevich responded that art can advance and develop for art's sake alone, saying that "art does not need us, and it never did".[citation needed] In 1934, Socialist Realism was officially imposed as the only permissible form of artistic expression in the Soviet Union, effectively banning avant-garde art.[3]
