Manege Affair
The Manege Affair was an episode when Nikita Khrushchev together with other Party leadership visited an anniversary art exhibition "30 Years of the Moscow Artists' Union" at Moscow Manege on December 1, 1962. It resulted in Khruschev's angry rant against "filth, decadence and sexual deviations" he saw along with the traditional works of Socialist Realism. After the visit, he arranged a campaign to tighten the grip of the Party over culture. This has been described as the beginning of the end of the Cultural Thaw in the Soviet Union. The episode is covered in detail in the book "Unofficial Art in the Soviet Union" by Paul Sjeklocha and Igor Mead and in other publications.
