The term Communist terrorism has been used to describe forms of organized violence used by some Marxist, socialist, communist or similar left-wing groups during revolutionary struggle, or during the consolidation or maintenance of power after revolutionary victory (see state terror).
Left wing revolutionary groups which engage in violence generally predicate it on one of two grounds:
The concept - adapted from historical materialism - that all remnants of the previous mode of production must be 'swept away' to solidify the new mode of production.
The belief among some later Marxists that lower classes lack an appropriate class consciousness (see false consciousness) and need to be shocked into awareness of their state. This kind of "liberating violence" is designed to spur the revolution on, often on the assumption that the lower classes will rise up once the weakness of the upper classes is exposed.
Western perspectives on terrorism committed by groups claiming adherence to Communist ideology
Terrorism in the form of 'communist fighting organizations' which operated in western Europe was seen as a threat by NATO and also by the Italian, German and British governments. In recent years, there has been a marked decrease in such terrorism, which has been substantially credited to the end of the Cold War and the fall of the U.S.S.R. However, at its apogee, communism was argued by some to be the major source of international terrorism (whether inspired by the ideology or supported by its states).
