Repression of science in the Soviet Union

Many fields of scientific research in the Soviet Union were banned or suppressed with various justifications. All humanities and social sciences were tested for strict accordance with dialectical materialism. These tests served as a cover for political suppression of scientists who engaged in research labeled as "idealistic" or "bourgeois". Many scientists were fired, others were arrested and sent to Gulags. The suppression of scientific research began during the Stalin era and continued after his death.

The ideologically motivated persecution damaged many fields of Soviet science.
