Rosa Luxemburg (1871 - 1919) is widely regarded as one of the most creative writers of modern socialism and the foremost female theoretician of European radicalism. Her wide-ranging and incisive works, which include studies on capitalism's inherent drive for global expansion, the relation between spontaneity and organization, and the inseparability of democracy and socialism, have made her a pole of attraction for theorists and activists around the world. Her fiercely independent intellect and uncompromising defense of human liberty speaks more powerfully to our era than to any other. This volume contains a new English translation of Luxemburg's most important book, The Accumulation of Capital as well as her response to its critics. Taken together, they constitute one of the most important Marxist studies of the globalization of capital.
