Twenty years after the breakdown of the Stalinist regimes in Eastern Europe the terror exercised by these regimes remains the main object of Communist Studies. However, there is also a small “boom” in research on communism as a social movement. Since 1989/90 several works on the history of the Communist party of Germany (KPD) in the Weimar republic have been published which understand the KPD as a social movement. They focus on the local conflicts, participants and fields of action of the then largest communist party outside the Soviet Union. They also draw in a fertile way on new methodical approaches, for example in writing a social history of the KPD. Beginning with a controversy about Hermann Weber’s concept of “Stalinization” the article delivers a short, historiographical overview of the most important more recent publications. It traces developments and controversies and offers a synopsis of KPD studies twenty years after the end of “actually existing socialism”.
