This course introduces and engages with historiographical questions central to our understanding of the Byzantine Empire from its inauguration in the fourth century to its fall in the fifteenth century. Sample sources - available in original and translation - are examined and analyzed using a variety of current methodological approaches. We consider aspects of political, economic, social, and cultural and intellectual history. The main areas of focus in a specific year will depend on the interests of the group. The aim is to provide students with concrete tools that will inform and strengthen their own research and teaching.
