On 15th January 1919, Rosa Luxemburg - one of the main leaders of the German Revolution - was brutally murdered by reactionary state forces, depriving the working class of one of its greatest fighters.

To commemorate Luxemburg's life, we republish here a video from an IMT school in London in 2014, where Marie Frederiksen (editor of the Danish Marxist newspaper Revolution) discusses the real revolutionary history, ideas, and traditions of Rosa Luxemburg, drawing out the valuable lessons we can learn for today.
