This volume is the first to contain all of Luxemburg's eloquent writings on the 1917 Russian and 1918-19 German Revolutions. It also contains articles, essays and manuscripts on the European socialist movement prior to World War I and her effort to rebuild the socialist movement on revolutionary foundations in its aftermath. Much of this material appears in English for the first time. Her incisive contributions on revolutionary strategy, the German and Russian Revolutions, and the transition to socialism reveal a profound commitment to radical democracy, which becomes evident as she elaborates on her lived experience with razor-sharp conceptualizations of the mass strike. Her democratic commitment is also highlighted in her deepening conflict with the bureaucratic conservatism afflicting the German Social Democratic Party.She is horrified yet at the same time grimly analytical while surveying the unfolding violence and brutality of the First World War.Deeply inspired by Russia's 1917 upsurge, she is nonetheless compelled to analyze and criticize fatal limitations of the Russian Revolution.Swept up in the revolutionary chaos sweeping through Germany in 1918-1919 which results in her own martyrdom, she gives voice to revolution's final testament: "I was, I am, I shall be."
