The critique of existing politics and the quest for an antagonistic and emancipatory practice of politics is one of the most important aspects of Karl Marx’s theoretical endeavour. The aim of the article is to retrace the various phases and forms of Marx’s critique of politics, the connec-tions but also distances between the critique of politics and the critique of political economy, and how the very experience of historical ruptures such as the Paris Commune led to a think-ing of a new practice of politics, a practice of struggle but also of experimentation and collective subaltern ingenuity.
