The Oxford Encyclopedia of American Military and Diplomatic History, a two-volume set, will offer both assessment and analysis of the key episodes, issues and actors in the military and diplomatic history of the United States. At a time of war, in which ongoing efforts to recalibrate American diplomacy are as imperative as they are perilous, the Oxford Encyclopedia will present itself as the first recourse for scholars wishing to deepen their understanding of the crucial features of the historical and contemporary foreign policy landscape and its perennially martial components.

Entries will be written by the top diplomatic and military historians and key scholars of international relations from within the American academy, supplemented, as is appropriate for an encyclopedia of diplomacy, with entries from foreign-based academics, in the United Kingdom and elsewhere.

The crucial importance of the subject is reflected in the popularity of university courses dedicated to diplomatic and military history and the enduring appeal of international relations (IR) as a political science discipline drawing on both. The Oxford Encyclopedia will be a basic reference tool across both disciplines - a potentially very significant market.
