Byzantine Studies at Notre Dame is a research-oriented field of inquiry devoted to the interdisciplinary study of the history and legacy of the Byzantine Empire (324–1453).
It investigates the long-lived and influential Byzantine Empire, whose territory stood between the Islamic Middle East and Catholic Europe. As the Greek continuation of the Eastern Roman Empire, its story spans the period from the ancient world to the early modern era.
In fashioning orthodox Christianity, in preserving and developing the intellectual and literary traditions of the Greco-Roman world, and in defining the notion of a Christian Empire, Byzantium became one of the great formative cultures in European history. Its legacy remains powerful to this day in Greece, the Balkans, Russia, the Black Sea, the Eastern Mediterranean, and among Orthodox communities throughout the world. 
The Anastos Collection is the heart of Byzantine Studies at Notre Dame. This superb research library, gathered by the renowned Byzantinist Milton V. Anastos, came to Notre Dame in 1997. Located beside the collections of the University's renowned Medieval Institute, this library allows scholars to pursue their research in a setting that encourages them to think of Byzantium in relation to the other societies and cultures prevalent in the ancient, medieval, and early modern worlds. Faculty and student researchers also benefit from the Stavros Niarchos Foundation Reading Room for Byzantine Studies, located on the seventh floor of the University’s Hesburgh Libraries.
