Paul Levi remains one of the most interesting and controversial figures in the early history of the Communist movement. As leader of the KPD after the murder of Rosa Luxemburg and Karl Liebknecht, he successfully built up a party of a third of a million members, but by 1921 Comintern pressure for `Bolshevisation' forced Levi's resignation and expulsion.This is the first English edition of Levi's writings and thus fills a gap in the canon of German communist literature.
