The Laws of War in the Late Middle Ages

The Laws of War in the Late Middle Ages examines the development and practice of military law and chivalric codes in medieval Europe. Through analysis of chronicles, legal texts, and military manuals, Maurice Keen traces how rules of warfare evolved from the 13th to 15th centuries. The book explores key concepts like declarations of war, treatment of prisoners, ransoms, and the distinction between legitimate and illegitimate combatants. Keen documents how these martial customs spread across European kingdoms and influenced combat, diplomacy, and knightly culture. Sections focus on practical matters such as the division of spoils, conduct during sieges, and procedures for settling military disputes. The text incorporates case studies from major conflicts including the Hundred Years' War. This scholarly work reveals how medieval societies sought to regulate warfare through an intricate system of laws, even as violence remained central to their way of life. The lasting influence of these martial codes on modern international law emerges as a significant theme.

🏰 Maurice Keen wrote this groundbreaking work while still a junior research fellow at Balliol College, Oxford, publishing it in 1965 when he was only 31 years old. ⚔️ The book was among the first scholarly works to extensively analyze how medieval military practices were influenced by the code of chivalry and Roman legal traditions. 👑 Keen's research revealed that ransoming captured nobles during warfare was not just a courtesy but a sophisticated economic system with established rules and price structures. 📜 The work draws heavily from previously untranslated medieval military manuals and legal treatises, including Christine de Pisan's "Book of Deeds of Arms and Chivalry." 🗡️ The book demonstrates how tournaments in the late Middle Ages served as both military training and legal precedent-setting events, where rules of engagement were tested and refined.
