How Europe went into the First World War. For a long time it was considered a foregone conclusion that the German Empire bore the main responsibility for the outbreak of the First World War because of its dreams of great power. In his groundbreaking new work, renowned historian and bestselling author Christopher Clark (Prussia) comes to a different assessment. Clark meticulously describes the interests and motivations of the most important political actors in the European metropolises and paints a picture of a complex world in which mutual mistrust, misjudgements, arrogance, expansionist plans and nationalist aspirations led to a situation in which a spark was enough to trigger the war, the devastating consequences of which hardly anyone was able to estimate. It is already apparent that "The Sleepwalkers" will be one of the most important new publications on the 100th anniversary of the outbreak of the First World War.
