In the not-quite-fifty years between the Franco-Prussian War and the end of the Great War, the German House of Hohenzollern resembled a soap opera in its familial intrigue. Emperor William I of Germany was a reactionary autocrat willing to place himself under the thumb of Otto von Bismarck, though his empress, Augusta, loathed the chancellor. Their son, Frederick III, comparatively liberal in his ideas and ignored for most of his life, ascended the throne in 1888 and died three months later — unfortunately for Germany. His wife, Victoria, the daughter of Queen Victoria of Great Britain, was shrewd and idealistic and Bismarck hounded her to her death. And their son, William II, was a flamboyant, power-mad megalomaniac who presided over the destruction of the dynasty. Aronson is less interested in the history of Germany, however, than in the interplay of personalities and hatreds within the family and between them and Bismarck, concentrating on such unofficial sources as court gossip of the era. If ever there was a ruling dynasty that deserved to fail, probably it was this one.
