Whether in the past or present – left-wing militancy is a firmly established part of political protest and movement culture in Germany. The “Bundesfachstelle Linke Militanz”, based at the Institute for Democracy Research at the University of Göttingen, has been examining various facets of this phenomenon over the past years. The Bundesfachstelle challenges common prejudices against left-wing militancy and clarifies the need for action from the perspective of democracy research. Concluding the project, funded by the federal program "Demokratie Leben!", this publication presents current findings on left-wing militancy in Germany, as well as experiences in addressing it. The contributions speak to various fields of analysis – such as housing struggles, antifascism, or climate activism – as well as scene-specific manifestations of issues like sexism, antisemitism, or radicalization. The publication also presents and critically discusses approaches to preventive and educational engagement with left-wing militancy. The diverse contributions from both research and practice collected in this volume enable scholars and professionals in political education and prevention work to engage in a focused examination of the challenges and possible courses of action in addressing left-wing militancy.
