Richard Muller, a leading figure of the German Revolution in 1918, is unknown today. As the operator and unionist who represented Berlin’s metalworkers, he was main organiser of the Revolutionary Stewards’, a clandestine network that organised a series of mass strikes between 1916 and 1918. With strong support in the factories, the Revolutionary Stewards were the driving force of the Revolution. By telling Muller’s story, this study gives a very different account of the revolutionary birth of the Weimar Republic. First published in German by Karl Dietz Verlag as Richard Muller – Der Mann hinter der November Revolution, Berlin, 2008, this Eenglish edition was completerly revised for the English speaking audience and contains new sources and recent literature.
