Was Bismarck the "German devil" or a “good European?” This is the radical alternative in which the first German Chancellor, thought to be the founder of modern Germany, is still considered. The book studies the social world, the political choices and the way power was wielded of the Chancellor. Was Bismarck a conservative or a revolutionary? Was he a dictator or an opportunist? Did he fuel nationalism and racial anti-Semitism at the end of the 19th c. or did he postpone its spread? Through these “facets” of Bismarck, the author examines the main stakes of contemporary German history and the most important European power.
