Left-wing extremists are avowed opponents of the state and social order of the Federal Republic of Germany, which they defame as an order of capitalism marked by racism and fascism. Depending on their ideological-political orientation – revolutionary-Marxist or anarchist – they are aiming at establishing a socialist/Communist system or a "society free from rulers” (anarchy).
The left-wing extremists´ forms of action are manifold: They comprise public manifestations, overt agitation with flyers, calls for action via posters, periodic publications, electronic communications media and running in elections and attempts to covertly influencing social groups. Violations of the law including overt or covert offences like causing damage to property, mass militancy and also inflicting bodily harm are partly regardsd as a means to pursue their political objectives.
For years now, the internal security of the Federal Republic of Germany has been threatened in particular by militant left-wing extremists, mainly from the anarchist-autonomous scene.
In German left-wing extremism the following ideolgical currents can be distinguished:
a revolutionary-marxist wing, comprising i.a. the "Deutsche Kommunistische Partei” (DKP / German Communist Party), the "Marxistisch-Leninistische Partei Deutschlands” (MLPD / Marxist-Leninist Party of Germany) and individual overtly extremist structures within the "Partei des Demokratischen Sozialismus” (PDS / Party of Democratic Socialism) and the "Left-wing Party PDS" like the "Kommunistische Plattform" (KPF / Communist Platform).
among the Trotzkyist groups which have been particularly active in the past years are "Linksruck” (Swing to the Left) and "Sozialistische Alternative” (SAV / Socialist Alternative).
the major part of the violence-prone left-wing extremists is made up of anarchist groups, among them those calling themselves "Autonomists".
