During a career that spanned sixty years, Gordon A. Craig (1913–2005) was one of America’s leading authorities on diplomatic history and international relations. This volume of previously uncollected essays (with one essay published here for the first time) includes several surveys, from different perspectives, of the field of diplomatic history; comparative studies of American and European conceptions of foreign policy and the balance of power; and essays on the theory and practice of diplomacy, focusing especially on the turbulent twentieth century.
