Rosa Luxemburg's writings reveal one of the most brilliant and passionate minds drawn to the revolutionary socialist movement. Through the letters, pamphlets and theorising, we see an outstanding social and economic theorist, a dedicated political activist and a devoted confidant. Providing an extensive overview of her writings, this volume contains a number of items never before anthologised. Her work was broad in scope tackling capitalism and socialism; globalisation and imperialism; history; war and peace; social struggles, trade unions, political parties; class, gender, race; the interconnection of humanity with the natural environment. The editors provide an extensive and informative introduction outlining and evaluating her life and thought. This is the most comprehensive introduction to the range of Rosa Luxemburg's thought.
