The history of human conflict matters. Armed struggle is a problem older than recorded history and the study of the past has been shaped by an interest in the challenges of war and peace. Members of this cluster have research and teaching interests in the history of military operations, institutions, and theory, as well as diplomacy and the impact of war on society and culture. The cluster includes award-winning faculty and graduate students whose work spans North America, Europe, and Asia. This cluster aims to break down the long-standing divisions between “old” and “new” military history by fostering an intellectually engaged community of scholars broadly interested in military affairs as an engine of change in human society. Faculty members teach a number of popular undergraduate courses and enthusiastically encourage undergraduate and graduate research. Current and former graduate students have won nationally-competitive research grants, published books with distinguished presses, and hold academic positions in both civilian and military institutions of higher education. We welcome applications from prospective graduate students interested in the study of war, diplomacy, and their impact on societies and cultures in the early modern and modern world.
