The story of global cooperation between nations and peoples is a tale of dreamers goading us to find common cause in remedying humanity’s worst problems.  But international institutions have also provided a tool for the powers that be to advance their own interests and stamp their imprint on the world.  Mark Mazower’s Governing the World tells the epic story of that inevitable and irresolvable tension—the unstable and often surprising alchemy between ideas and power. From the beginning, the willingness of national leaders to cooperate has been spurred by crisis: the book opens in 1815, amid the rubble of the Napoleonic Empire, as the Concert of Europe was assembled with an avowed mission to prevent any single power from dominating the continent and to stamp out revolutionary agitation before it could lead to war.
