Book excerpt: The continuity issue has been a theme in German historiography for half a century. Historians have examined the foreign policy of Wilhelmine and Nazi Germany that led to two world wars. Dr. William Young examines the continuity of German Foreign Office influence in the formulation of foreign policy under the leadership of Otto von Bismarck (1862-1890), Kaiser William II (1888-1918), the Weimar Republic (1919-1933), and Adolf Hitler (1933-1945). He stresses the role and influence of strong German leaders in the making of policy and the conduct of foreign relations. German Diplomatic Relations 1871-1945 will be of value to individuals interested in the history of Germany, Modern Europe, and International Relations.
