Dr. Walker Cosgrove

Professor of History

While trained as a medievalist, I am broadly interested in all areas of history, particularly pre-modern religious history. In my ancient and medieval history classes we attempt to understand how prophets, poets, dramatists, philosophers, and theologians wrestled with the human condition and life's most persistent questions. In these classes we interact with some of the world's most remarkable writers and thinkers. Among them are Homer, Aeschylus, Sophocles, Plato, Aristotle, Virgil, Augustine, and the anonymous medieval poets of Beowulf, Song of Roland, El Cid, and Sir Gawain and the Green Knight, as well as St. Benedict, St. Bonaventure, and Dante. In all of these we find works that are as alive and relevant as the day they were written. I also co-teach a class on the Italian Renaissance, which includes a trip to Florence, Italy.

Another area that interests me is "historical memory." This means how various peoples remember certain historical events and eras, and how those "memories" get passed down through the ages and become an "objective" history to them. I consider the issue of "historical memory" in all of my courses to some degree. I am especially interested in "historical memory" in my courses in on the crusades and Islamic/Middle Eastern history. In the crusades class we certainly study the crusades in their medieval world, but we also consider how the crusades relate to our own contemporary society and how they are "remembered" today in the West and the Middle East. In my Muslim World class we consider how various Islamic groups view the birth, growth, and development of Islam. In my Modern Middle East class, we examine how certain events acquire significance for various ethnic and tribal peoples, as well as how the past is remembered in such issues as the Israel-Palestine conflict, the Arab Spring, and Arab-Persian-Turkish interactions. We also discuss how radical Muslims think about their own history.
