Back in 1999, the Rosa Luxemburg Foundation chose the name of probably the best-known socialist in the German-speaking world. Many people associate her and her work with consistent, intelligent, and honest left-wing politics. Rosa Luxemburg (1871–1919) fascinates as an emancipated, versatile, and even artistic woman who lived and worked in a time that continues to carry weighty implications for the political Left today. Her views had no chance in the socialist and workers’ movement in the last century; she was ahead of her time. Yet for today’s political Left, her approaches prove extraordinarily inspiring. The name Rosa Luxemburg has become a matter of identity for the Foundation—perhaps even more than was foreseeable when the name was chosen over 20 years ago. That is why we are also dedicated to what is associated with Rosa Luxemburg: ruthless criticism of capitalism and the articulation of convincing alternatives.
