1356: Poitiers, the King's Capture, and Political Disaster
p5John II the Good: Captivity, Internal Crisis, and the Treaty of Brétigny (1350–1364) · HIGH MIDDLE AGES
The Battle of Poitiers (1356) is one of the great disasters of the first phase of the Hundred Years’ War. John II is taken prisoner: the event strikes at the heart of the very idea of sovereignty, for the king is not merely a military commander, but the symbolic and legal pivot of the kingdom.
⚔️ A Defeat That Disorganizes Power
The king’s capture triggers an immediate crisis: who decides, who levies taxes, who negotiates? The Dauphin Charles must ensure governmental continuity, while princes, cities, and the Estates General seek to influence decisions.
🧩 Military Fragilties Revealed
Despite reform attempts (ordinances of 1351), the French army remains traversed by feudal logics: rivalries in command, unequal tactical discipline, and difficult coordination between contingents. Faced with a better-organized English army, backed by archers and a defensive posture, these weaknesses weigh heavily.
