The Internationalists

'It will change the way you remember the 20th century and read the news in the 21st' Steven Pinker

'A clarion call to preserve law and order across our planet' Philippe Sands

'A fascinating and important book ... given the state of the world, The Internationalists has come along at the right moment' Margaret MacMillan, Financial Times

Since the end of the Second World War, we have moved from an international system in which war was legal, and accepted as the ultimate arbiter of disputes between nations, to one in which it was not. Nations that wage aggressive war have become outcasts and have almost always had to give up their territorial gains. How did this epochal transformation come about? This remarkable book, which combines political, legal, and intellectual history, traces the origins and course of one of the great shifts in the modern world.

'Sweeping and yet personable at the same time, The Internationalists explores the profound implications of the outlawry of war. Professors Oona Hathaway and Scott Shapiro enrich their analysis with vignettes of the many individuals (some unknown to most students of History) who played such important roles in this story. None have put it all together in the way that Hathaway and Shapiro have done in this book' Paul Kennedy

'In this timely, elegant and powerful book, Oona Hathaway and Scott Shapiro help us understand the momentous significance of the individuals who imagined an end to war. As the world stands on the cusp of a return to an earlier age, The Internationalists is a clarion call to preserve law and order across our planet' Philippe Sands
