The First World War was a disaster whose repercussions are still felt. This book goes behind the battlefronts to focus on the politics of the war. David Stevenson explains why the governments of the day turned to violence in pursuit of their aims; why the resulting conflict expanded to global dimensions; why it could not be ended by compromise; the international significance of the Russian revolution and the entry into the war of the USA; and why the eventual peace settlement took the form it did.The First World War and International Politics sets the events of 1914-18 in the context of twentieth-century world history; it also illuminates the political background of wars in general, and illustrates Clausewitz's dictum that `war...is a true political instrument, a continuation of political activity by other means.'
