“Medieval” has both a specific and a generic sense. The specific sense refers to the history of western Europe between the fall of Rome and the Renaissance or early modernity. Its geography is broadly coterminous with the use of Latin as a learned language and with the jurisdiction of the Church of Rome. The huge majority of practising “medievalists” study England, France, northern Italy, and to a slightly lesser extent the German lands, and there is now a significant interest in Scandinavia. Slavic cultures and Byzantium are considered separate fields. Southern Spain and southern Italy fall into an almost different field, or quasi-field, the “medieval Mediterranean,” entry into which virtually requires that one work on “contacts” across religious communities. This specific sense of the medieval world accounts for the vast majority of papers given at medieval conferences, the articles published in medieval journals, and the areas of expertise of those hired as medievalists. These areas include English peasants, French queens, and German nuns, but rarely Slavic chiefs, Byzantine tax systems, or Islamic thought.
