“An original book…about individuals who used ideas to change the world” (The New Yorker)—the fascinating exploration into the creation and history of the Paris Peace Pact, an often overlooked but transformative treaty that laid the foundation for the international system we live under today.
In 1928, the leaders of the world assembled in Paris to outlaw war. Within the year, the treaty signed that day, known as the Peace Pact, had been ratified by nearly every state in the world. War, for the first time in history, had become illegal. But within a decade of its signing, each state that had gathered in Paris to renounce war was at war. And in the century that followed, the Peace Pact was dismissed as an act of folly and an unmistakable failure. This book argues that the Peace Pact ushered in a sustained march toward peace that lasts to this day.
A “thought-provoking and comprehensively researched book” (The Wall Street Journal), The Internationalists tells the story of the Peace Pact through a fascinating and diverse array of lawyers, politicians, and intellectuals. It reveals the centuries-long struggle of ideas over the role of war in a just world order. It details the brutal world of conflict the Peace Pact helped extinguish, and the subsequent era where tariffs and sanctions take the place of tanks and gunships.
The Internationalists is “indispensable” (The Washington Post). Accessible and gripping, this book will change the way we view the history of the twentieth century—and how we must work together to protect the global order the internationalists fought to make possible. “A fascinating and challenging book, which raises gravely important issues for the present…Given the state of the world, The Internationalists has come along at the right moment” (The Financial Times).

“A fascinating and challenging book, which raises gravely important issues for the present... Given the state of the world, The Internationalists has come along at the right moment.”—Margaret MacMillan, The Financial Times
"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, Professor of History, Yale University, and author of The Rise and Fall of Great Powers
"The Internationalists, by Yale law school professors Scott Shapiro and Oona Hathaway, is a provocative, fascinating, and significant book. It deserves to be on the bookshelf of all serious students of foreign affairs and promises to rattle conventional wisdom as well as foster a healthy debate."—Jay Winik, author of April 1865 and 1944, Historian-in-Residence, Council on Foreign Relations
“A searching analysis of contending views of state violence and warfare….Rich in implication, particularly in a bellicose time, and of much interest to students of modern history and international relations.”—Kirkus Reviews
“Hathaway and Shapiro adopt a fundamentally revisionist perspective on the oft-dismissed Kellogg-Briand Peace Pact of 1928, positing that the agreement ‘marked the beginning of the end’ of war between states. The pact inspired the human-rights revolution, the use of economic sanctions, and the creation of international organizations focusing on peace….the authors provocatively argue that, since 1945, conquest ‘has nearly disappeared’ as ‘an accepted procedure for changing borders’.…Hathaway and Shapiro’s conclusion can be debated—but not easily dismissed.”—Publishers Weekly
"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 maintain law and order across our planet."—Philippe Sands QC, Professor of Law, University College London and author of East West Street
“An engrossing narrative that provides a new framework for interpreting international relations over the previous five centuries.”—Library Journal, Starred Review
