From the Viking invasions to the Crusades to the Hundred Years’ War, wars were crucial agents of change in medieval Europe. The Oxford Encyclopedia of Medieval Warfare and Military Technology examines all aspects of warfare and military technology in medieval times. Approximately 1,000 articles signed by the leading experts in medieval military history provide an exhaustive and accurate view of how and why wars were waged throughout Europe, the Byzantine Empire, and the Crusader States between 500 c.e. to 1500.

The Oxford Encyclopedia of Medieval Warfare and Military Technology contains articles on military leaders; battles; sieges; individual fortresses; and military technology focusing on subjects such as armor, navigational techniques, and siege warfare tactics. In addition, each regional overview—such as Britain, the Byzantine Empire, and Hungary—includes a discussion of primary sources, an introductory narrative, and an entry on historiography providing a depth and breadth of coverage not found in any other resource on the subject.
