Anti-Soviet Agitation and Propaganda (ASA) was a
criminal offence in the
Soviet Union. To begin with the term was interchangeably used with
counter-revolutionary agitation. The latter term was in use immediately after the first
Russian Revolution in February 1917. The offence was codified in criminal law in the 1920s, and revised in the 1950s in two articles of the RSFSR Criminal Code. The offence was widely used against
Soviet dissidents.
