Modern diplomacy began in the fifteenth century when the Italian city-states established resident embassies at the courts of their neighbors. By the sixteenth century, the forms and techniques of the new continuing diplomacy had spread northward to be further developed by the emerging European powers. “The new Italian institution of permanent diplomacy was drawn into the service of the rising nation-states. and served, like the standing army of which it was the counterpart, at once to nourish their growth and foster their idolatry. It still serves them and must go on doing so as long as nation-states survive.” Garrett Mattingly, author of Catherine of Aragon and The Armada, here tells the story of Western diplomacy in its formative period and explains the evolution of the diplomat’s function. His able and lively discussion also forms, in effect, a history of Western Europe from an entirely fresh point of view. “Garrett Mattingly develops his theme with historical skill, a sense of the relevance of his subject to modern problems, and a literary grace all too rare in works of serious scholarship.”-New York Herald Tribune “An important book...carefully and elegantly written.”-Times Literary Supplement “Presents the many facets of a highly complex subject in a way which is as readable as it is scholarly.”-American Historical Review “A remarkable book: bold, scholarly and original, it will appeal equally to the expert and to the historically-minded general reader.”-New Statesman and Nation
