No political parties of present-day Germany are separated by a wider gulf than the two parties of labor, one democratic and reformist, the other totalitarian and socialist-revolutionary. Social Democrats and Communists today face each other as bitter political enemies across the front lines of the Cold War; yet they share a common origin in the Social Democratic Party of Imperial Germany. How did they come to go separate ways? By what process did the old party break apart? How did the prewar party prepare the ground for the dissolution of the labor movement in World War I, and for the subsequent extension of Leninism into Germany? To answer these questions is the purpose of Carl Schorske's study.

This groundbreaking comparative study rediscovers the socialists of Russia’s borderlands, upending conventional interpretations of working-class politics and the Russian Revolution. Researched in eight languages, Revolutionary Social Democracy challenges long-held assumptions by scholars and activists about the dynamics of revolutionary change.

Not to repeat past mistakes: the sudden resurgence of a sympathetic interest in social democracy is a response to the urgent need to draw lessons from the history of the socialist movement. After several decades of analyses worthy of an ostrich, some rudimentary facts are being finally admitted. Social democracy has been the prevalent manner of organization of workers under democratic capitalism. Reformist parties have enjoyed the support of workers.

Beyond France’s own national historiography, the French Revolution was a fundamental point of reference for the nineteenth-century socialist movement. As Jean-Numa Ducange tells us, while Karl Marx never wrote his planned history of the Revolution, from the 1880s the German and Austrian social-democrats did embark on such a project. This was an important moment for both Marxism and the historiography of the French Revolution. Yet it has not previously been the object of any overall study. The French Revolution and Social Democracy studies both the social-democratic readings of the foundational revolutionary event, and the place of this history in militant culture, as seen in sources from party educationals, to leaflets and workers’ calendars. First published in 2012 as La Révolution française et la social-démocratie. Transmissions et usages politiques de l’histoire en Allemagne et Autriche, 1889–1934 by Presses Universitaires de Rennes in 2012.

Dr Ryder begins this full-scale treatment of the German Revolution by summarizing the origins and development of German Social Democracy up to the party's historic vote for war credits on 4 August 1914. He then considers the socialists' attitudes to the war, notably in relation to the controversial question of annexations, and traces the growth of a threefold split inside the socialist party.
