We review the diplomatic landscape of Europe on the eve of war in the summer of 1914—and then follow the dizzying cascade of events that followed after the assassination of the Archduke Franz Ferdinand in Sarajevo on June 28, 1914. We trace on the ensuing crisis that ricocheted through embassies, banquet halls, and barracks all across Europe, and plunged all the great powers of the continent into a war that soon spread around the world.
