Gietinger is less adept at exploring the significance of the murders, which he seems to think we can take as read. Although there’s a new preface, Verso haven’t thought through how to make the book relevant to British readers or to 2019, sidestepping the important question of what her death might mean to us now. Gietinger tells us that these killings were “one of the great tragedies of the twentieth century”. But why? What could Luxemburg and Liebknecht have achieved had they been allowed to live?...Gietinger writes that when the SPD sank Luxemburg’s body in the Landwehr Canal, they were “sinking the Weimar Republic along with it”. He doesn’t explain why this is the case, but this is one of several moments of mourning in this book – welcome intrusions in the forensic scrupulousness.
