A magisterial history of international government, from the award-winning author of Dark Continent and Hitler's Empire In 1815 the shocked and exhausted victors of the decades of fighting that had engulfed Europe for a generation agreed to a new system for keeping the peace. Instead of independent states changing sides, doing deals and betraying one another, a new, collegial 'Concert of Europe' would ensure that the brutal chaos of the Napoleonic Wars never happened again. Mark Mazower's remarkable new book recreates two centuries of international government - the struggle to spread values and build institutions to bring order to an anarchic and dangerous state system.
