Jonathan Steinberg draws heavily on contemporary writings, allowing Bismarck's friends and foes to tell the story. What rises from these pages is a complex giant of a man: a hypochondriac with the constitution of an ox, a brutal tyrant who could easily shed tears, a convert to an extreme form of evangelical Protestantism who secularized schools and introduced civil divorce. Bismarck may have been in sheer ability the most intelligent man to direct a great state in modern times. His brilliance and insight dazzled his contemporaries. But all agreed there was also something demonic, diabolical, and overwhelming in Bismarck's personality. He was a kind of malign genius who, behind the various postures, concealed an ice-cold contempt for his fellow human beings and a drive to control and rule them. As one contemporary noted: "the Bismarck regime was a constant orgy of scorn and abuse of mankind, collectively and individually."

A brilliant study in power, this comprehensive biography brings Bismarck to life, revealing the stark contrast between the "Iron Chancellor's" unmatched political skills and his profoundly flawed human character.
