“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).

An untold story of scientists and engineers who changed the course of World War I Roy R. Manstan's new book documents the rise of German submarines in World War I and the Allies' successful response of tracking them with innovative listening devices—precursors to modern sonar. The Listeners: U-boat Hunters During the Great War details the struggle to find a solution to the unanticipated efficiency of the German U-boat as an undersea predator. Success or failure was in the hands and minds of the scientists and naval personnel at the Naval Experimental Station in New London, Connecticut. Through the use of archival materials, personal papers, and memoirs The Listeners takes readers into the world of the civilian scientists and engineers and naval personnel who were directly involved with the development and use of submarine detection technology during the war.

Despite the increasingly futile, bloody struggles for territory that had characterised the Eastern Front the previous year, the German and Austro-Hungarian commands held high hopes for 1916. After the success of the 1915 Gorlice–Tarnów Offensive, which had driven Russia out of Galicia and Poland, Germany was free to renew its efforts in the west. Austria-Hungary, meanwhile, turned its attention to defeating Italy. In an attempt to relieve pressure on their British and French allies at the Somme and Verdun, Russia launched one of the bloodiest campaigns in the history of warfare. General Brusilov's June advance was quickly characterised by innovative tactics, including the use of shock troops – a tactic that German armies would later adapt to great effect. The momentum continued with Romania's entry into the war and the declaration by the Central Powers of a Kingdom of Poland – two events which would radically transform the borders of post-war Europe. Drawing on first-hand accounts and archival research, internationally renowned historian Prit Buttar presents a dramatic account of an explosive year on the Eastern Front, one that gave Russia its greatest success on the battlefield but plunged the nation into revolution at home.
