On June 28, 1914, Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were murdered in Sarajevo – triggering a series of bad decisions that culminated in World War I. A century later, the world is again roiled by conflict and uncertainty, exemplified in the Middle East, Ukraine, and the East and South China Seas. Can an understanding of the mistakes made in 1914 help the world to avoid another major catastrophe? To be sure, the global order has changed dramatically over the last hundred years. But the growing sense that we have lost control over history, together with serious doubts about the capabilities and principles of our leaders, lends a certain relevance to the events in Sarajevo in 1914.
