 The Sinyavsky-Daniel case is widely considered to mark the end of the liberal Khrushchev Thaw period and the rise of political repression in the Soviet Union under hardliner Leonid Brezhnev, and a major starting impulse for the Soviet dissident movement.Andrei Sinyavsky, a well-known literary critic and writer in the Soviet Union, and his friend Yuli Daniel, a writer and translator, had begun sending their works to be published in the West due to strong censorship in the Soviet Union.Sinyavsky and Daniel often wrote topical stories and novellas that were satirical or critical of Soviet society, and would naturally be rejected for publication by the ruling Communist Party of the Soviet Union (CPSU).
