This is a collection of Rosa Luxemburg's letters to her lover and comrade, Leo Jogiches which reveal another side to her character. This translation captures her passionate and fearless nature, a woman who refused to let politics obliterate her private life, refused to compromise, refused to accept that she could be faced with a choice between either her lover or her political career. The letters show Luxemburg at her most intimate and personal, but also shed light on the dramatic developments on the revolutionary left of the era. The letters are annotated where necessary and each section is preceded by a short note giving the context in which the letters were exchanged. An introductory essay provides the background to the stormy relationship and to the history of the period.
