Certain scientific fields in the Soviet Union were suppressed after being labeled as ideologically suspect.[2][3] In some cases the consequences of ideological influences were dramatic. The suppression of research began during the Stalin era and continued, in softened forms, after his regime.[4]Leon Trotsky had defended Einstein’s theory of relativity in Soviet intellectual circles but this became an anathema during the Stalin era and was only rehabilitated following the latter’s death.[5]
