Abstract
The divergent views held by historians and sociologists as to what does and does not constitute nationalism will, I hope, provide me with some excuse for not attempting here a general definition of this phenomenon. Nor will I presume to adjudicate between the opinions of scholars like Hans Kohn who, confining their attention to Western Europe, will not hear of nationalism before the rise of modern states between the sixteenth and the eighteenth century, and of historians like G. G. Coulton who, after surveying the policy of the Papacy, the life of the Universities, the internal frictions in the monasteries and the history of medieval warfare, concluded that nationalism, which had been developing in Western Europe since the eleventh century, became a basic factor in European politics by the fourteenth. My paper is concerned with the medieval history of Eastern Europe: an area which I propose to define, by combining a geographical with a cultural criterion, as the group of countries which lay within the political or cultural orbit of Byzantium. The subject is vast and complex, and I can do no more than select a few topics for discussion. These I would like to present as arguments in support of three theses.
