To many, Eastern Europe is nearly synonymous with Slavic Europe. The equation is certainly not new. To Hegel, the “East of Europe” was the house of the “great Sclavonic nation,” a body of peoples which “has not appeared as an independent element in the series of phases that Reason has assumed in the World”. If necessary, Europe may be divided into western and eastern zones along a number of lines, according to numerous criteria. Historians, however, often work with more than one set of criteria. The debate about the nature of Eastern Europe sprang up in Western historiography in the days of the Cold War, but despite Oskar Halecki's efforts explicitly to address the question of a specific chronology and history of Eastern Europe, many preferred to write the history of Slavic Europe, rather than that of Eastern Europe. Today, scholarly interest in Eastern Europe focuses especially on the nineteenth and twentieth centuries, the period of nationalism. The medieval history of the area is given comparatively less attention, which often amounts to slightly more than total neglect. For most students in medieval studies, Eastern Europe is marginal and East European topics simply exotica. One reason for this historiographical reticence may be the uneasiness to treat the medieval history of the Slavs as (Western) European history.
