Iron Kingdom. The Rise and Downfall of Prussia, 1600-1947; Penguin, 2007

Winner of the Wolfson History Prize, Christopher Clark's Iron Kingdom: The Rise and Downfall of Prussia 1600-1947 is a compelling account of a country that played a pivotal role in Europe's fortunes and fundamentally shaped our world.

Prussia began as a medieval backwater, but transformed itself into a major European power and the force behind the creation of the German empire, until it was finally abolished by the Allies after the Second World War.

With great flair and authority, Christopher Clark describes Prussia's great battles, dynastic marriages and astonishing reversals of fortune, its brilliant and charismatic leaders from the Hohenzollerns of Brandenburg to Bismarck and Frederick the Great, the military machine and the progressive, enlightened values on which it was built.
