退廃芸術
On 18 July 1931, the USDS announced a public, open, international competition, with entries due by 20 October (later extended to 1 December 1931). In September, the USDS amended the terms and explained the design of the Palace would not be awarded to a single architect or a group or firm. The USS claimed no single group could overcome the project's unprecedented challenges; it requires a joint effort of "all living creative forces of the Soviet society". The message foreshadowed the imminent nationalization of the formerly independent professional community, but no one, even the Party insiders like Iofan, Alabyan or Shchusev, could predict the outcome. Another covert purpose of the competition—suppression of undesirable architecture in a manner similar to the "Degenerate art" campaign in Germany—would be revealed by Alexey Tolstoy (another Party insider) later, just before the announcement of the winners. Tolstoy clearly warned the architects that Gothic architecture, "American skyscraperism" and "corbusianism" had become distinctly unwanted.
