The results, fixed at the Congress of Vienna in 1815, not only laid the foundations of the European world we know; it put in place a social order and a security system that lie at the root of many of the problems which dog the world today. Although the defining moments took place in Vienna, and the principle players included Tsar Alexander I of Russia, the Austrian Chancellor Metternich, the Duke of Wellington and the French master of diplomacy Talleyrand, as well as Napoleon himself, the accepted view of the gathering of statesmen reordering the Continent in elegant salons is a false one. Many of the crucial questions were decided on the battlefield or in squalid roadside cottages amid the vagaries of war. And the proceedings in Vienna itself were not as decorous as is usually represented.

Drawing on a wide range of first-hand sources in six languages, which include not only official documents, private letters, diaries and first-hand accounts, but also the reports of police spies and informers, Adam Zamoyski gets below the thin veneer of courtliness and reveals that the new Europe was forged by men in thrall to fear, greed and lust, in an atmosphere of moral depravity in which sexual favours were traded as readily as provinces and the 'souls' who inhabited them. He has created a chilling account, full of menace as well as frivolity.
