The Antifa movement in Germany is a political current composed of multiple far-left, autonomous, militant anti-fascist groups and individuals. It has existed in different eras and incarnations, and takes its name from the historical Antifaschistische Aktion, an organisation affiliated with the Communist Party of Germany (KPD) that existed from 1932 to 1933. Antifa committees emerged across Germany after WWII with the involvement of trade unionist, socialist, communist and Christian groups; in the Soviet occupation zone and East Germany these were absorbed into the ruling Socialist Unity Party of Germany and became part of its official apparatus, ideology and language.
