It is not often that a great power vanishes into thin air overnight, but that is exactly what happened to Prussia. With the stroke of a pen, a state that had stood at the center of European politics for centuries was abruptly ordered off the stage of history, dismissed as a bearer of militarism and reaction in Germany by Law No. 46 of the Allied Control Council, signed on Feb. 25, 1947.  Few tears were shed. But Iron Kingdom, Christopher Clarks stately, authoritative history of Prussia from its humble beginnings to its ignominious end, presents a much more complicated and compelling picture of the German state, which is too often reduced to a caricature of spiked helmets and polished boots. Prussia and its army were inseparable, but Prussia was also renowned for its efficient, incorruptible civil service; its innovative system of social services; its religious tolerance; and its unrivaled education system, a model for the rest of Germany and the world. This too was Prussia  a tormented kingdom that, like a tragic hero, was brought down by the very qualities that raised it up.  Mr. Clark, a senior lecturer in modern European history at Cambridge University, does an exemplary job. A lively writer, he organizes masses of material in orderly fashion, clearly establishing his main themes and pausing at crucial junctures to recapitulate and reconsider. Prussia, a self-invented artifact right down to its name, demands the kind of careful demythologizing that it receives from Mr. Clark, who gently but insistently exposes the flaws in most of the received wisdom about his subject. A result is an illuminating, profoundly satisfying work of history, brightened by vivid character sketches of the principals in his drama.  To take just one example of many, Mr. Clark challenges the notion that Frederick William I (1713-40) achieved what one 19th-century Prussian historian called the perfection of absolutism. While it is true, Mr. Clark acknowledges, that Frederick curbed the power of the nobility and from Berlin imposed centralized rule over the region known as the Mark Brandenburg, posterity has greatly exaggerated the power of the nascent Prussian state, whose officials numbered not more than a few hundred men.  Official documents passed to their destinations through the hands of pastors, vergers, innkeepers and schoolchildren who happened by, Mr. Clark writes. In one principality an investigation found that most government communications took up to 10 days to travel just a few miles, partly because their first stop was the local tavern, where they were unsealed, passed around and discussed over glasses of brandy, finally arriving at their destinations, in the words of investigators, so dirtied with grease, butter or tar that one shudders to touch them. The supposedly well-oiled machine of Prussian absolutism squeaked and creaked, especially in the hinterlands.  The myth of Prussian militarism, likewise, receives careful scrutiny. A large, disciplined army transformed the Mark Brandenburg, with its poor soil, scant natural resources and lack of access to the sea, into a regional power. But the militarization of society did not really begin until the late 19th century, and even then Mr. Clark questions whether the Prussian experience set it apart from the rest of Europe. France and Britain were equally committed to empire-building and military might. The civility and anti-militarism of British society were perhaps more a matter of self-perception than a faithful representation of reality, he writes. It is also worth noting that the German peace movement developed on a scale unparalleled elsewhere.  Similarly, in the 1930s conservative Prussian landowners provided the Nazis with widespread enthusiastic support, but most of the officers who plotted against Hitler came from the Prussian officer corps. Prussia, under the Social Democrat Otto Braun and his police chief, Albert Grzesinski, was a stronghold of democracy in the days leading up to the Nazi assumption of power, and Mr. Braun, in his own way, epitomized the Prussian ideal.  His endless appetite for work, his fastidious attention to detail, his dislike of posturing and his profound sense of the nobility of state service were all attributes from the conventional catalog of Prussian virtues, Mr. Clark writes.  Prussian problems and flaws were acute, intractable and ultimately fatal. If geography is destiny, Prussia was doomed from the start. Surrounded by hostile powers, it could secure its future only by acquiring territory, but each acquisition created new, troubled borders, which fed the appetite for conquest.  Under rulers like Frederick William (the Great Elector, 1640-88) and Frederick the Great (1740-86), the modest state of Brandenburg played a weak hand brilliantly, selling its favors to the highest bidder, fighting or remaining neutral as self-interest demanded, arranging advantageous dynastic marriages and gradually acquiring coveted parcels of territory, including the Duchy of Prussia.  There could be no happy ending to Prussias restless ambitions, driven by a profound sense of insecurity that deepened with German unification. A patched-together kingdom assumed primacy within a patched-together country.  There was an unsettling sense that what had so swiftly been put together could also be undone, that the empire might never acquire the political or cultural cohesion to safeguard itself against fragmentation from within, Mr. Clark writes. Deep-seated fears of encirclement by hostile powers, a purely Prussian obsession, he writes, found expression in the Schlieffen plan of World War I, which called for lightning offensives against France and then Russia.  Perhaps most dangerous, Prussias security depended on an army that had never been subject to civilian control. It was, Mr. Clark writes, a praetorian guard under the personal command of the king.  This, he adds, was Prussias most fateful legacy to the new Germany. And, he might have added, to the rest of the world.
Christopher Clark presents an authoritative history of a state remembered for its militarism, but which had benign qualities too.
