Anti-Soviet agitation and propaganda (ASA) (Russian: антисове́тская агита́ция и пропага́нда (АСА)) was a criminal offence in the Soviet Union. Initially, the term was interchangeably used with counter-revolutionary agitation. The latter term was in use immediately after the October Revolution of 1917. The offence was codified in criminal law in the 1920s, and revised in the 1950s in two articles of the Russian SFSR Criminal Code. The offence was widely used against Soviet dissidents.[1]
