NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New York Times Book Review • The Economist • The Christian Science Monitor • Bloomberg Businessweek • The Globe and Mail From the bestselling and award-winning author of Paris 1919 comes a masterpiece of narrative nonfiction, a fascinating portrait of Europe from 1900 up to the outbreak of World War I. The century since the end of the Napoleonic wars had been the most peaceful era Europe had known since the fall of the Roman Empire. In the first years of the twentieth century, Europe believed it was marching to a golden, happy, and prosperous future. But instead, complex personalities and rivalries, colonialism and ethnic nationalisms, and shifting alliances helped to bring about the failure of the long peace and the outbreak of a war that transformed Europe and the world. The War That Ended Peace brings vividly to life the military leaders, politicians, diplomats, bankers, and the extended, interrelated family of crowned heads across Europe who failed to stop the descent into war: in Germany, the mercurial Kaiser Wilhelm II and the chief of the German general staff, Von Moltke the Younger; in Austria-Hungary, Emperor Franz Joseph, a man who tried, through sheer hard work, to stave off the coming chaos in his empire; in Russia, Tsar Nicholas II and his wife; in Britain, King Edward VII, Prime Minister Herbert Asquith, and British admiral Jacky Fisher, the fierce advocate of naval reform who entered into the arms race with Germany that pushed the continent toward confrontation on land and sea. There are the would-be peacemakers as well, among them prophets of the horrors of future wars whose warnings went unheeded: Alfred Nobel, who donated his fortune to the cause of international understanding, and Bertha von Suttner, a writer and activist who was the first woman awarded Nobel’s new Peace Prize. Here too we meet the urbane and cosmopolitan Count Harry Kessler, who noticed many of the early signs that something was stirring in Europe; the young Winston Churchill, then First Lord of the Admiralty and a rising figure in British politics; Madame Caillaux, who shot a man who might have been a force for peace; and more. With indelible portraits, MacMillan shows how the fateful decisions of a few powerful people changed the course of history. Taut, suspenseful, and impossible to put down, The War That Ended Peace is also a wise cautionary reminder of how wars happen in spite of the near-universal desire to keep the peace. Destined to become a classic in the tradition of Barbara Tuchman’s The Guns of August, The War That Ended Peace enriches our understanding of one of the defining periods and events of the twentieth century. Praise for The War That Ended Peace “Magnificent . . . The War That Ended Peace will certainly rank among the best books of the centennial crop.”—The Economist “Superb.”—The New York Times Book Review “Masterly . . . marvelous . . . Those looking to understand why World War I happened will have a hard time finding a better place to start.”—The Christian Science Monitor “The debate over the war’s origins has raged for years. Ms. MacMillan’s explanation goes straight to the heart of political fallibility. . . . Elegantly written, with wonderful character sketches of the key players, this is a book to be treasured.”—The Wall Street Journal “A magisterial 600-page panorama.”—Christopher Clark, London Review of Books

The First World War followed a period of sustained peace in Europe during which people talked with confidence of prosperity, progress and hope. But in 1914, Europe walked into a catastrophic conflict which killed millions of its men, bled its economies dry, shook empires and societies to pieces, and fatally undermined Europe's dominance of the world. Beginning in the early 19th century, and ending with the assassination of Archduke Franz Ferdinand, historian Margaret MacMillan uncovers the huge political and technological changes, national decisions and - just as important - the small moments of human muddle and weakness that led Europe from peace to disaster.
