The term Communist terrorism refers to left-wing terrorism committed by various movements that claim adherence to the doctrines of Karl Marx during a revolutionary struggle, as well as to state terror during the consolidation of power after revolutionary victory.
Many Orthodox Communists have emphasized revolution over reform and offered a vision of the working classes sweeping away the capitalist system. Some of these communist movements and parties had adopted armed struggle and seen terrorism as a viable option; on the other hand some dissident leftist terrorist organisations, including some of those in Western democracies, had little faith in the working classes, believing them to have been corrupted and sometimes argued that "liberating violence" was necessary to spur the revolution on.
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).

Karl Kautsky (1919). "Revolution and Terror". Terrorism and Communism. Kautsky said: "It is, in fact, a widely spread idea that Terrorism belongs to the very essence of revolution, and that whoever wants a revolution must somehow come to some sort of terms with terrorism. As proof of this assertion, over and over again the great French Revolution has been cited." (Translated by W.H.
