Treaty of Brétigny

Overview

The Treaty of Brétigny is the 1360 Anglo-French settlement that exchanged Edward III’s French crown claim for a greatly enlarged sovereign Aquitaine, but did not create a durable political order.

Current Profile

The treaty follows Edward’s failed effort to take Reims and Paris and the Duke of Lancaster’s warning against risking decades of gains in one battle. Its terms resemble the earlier Windsor settlement: England receives extensive territory without French overlordship, while Edward renounces the French throne claim.

The episode treats Brétigny as a strong but unstable English result. War damage, free companies, ransom obligations, taxation, and the unresolved ability of Aquitanian subjects to appeal to Charles V undermine implementation. The Black Prince’s refusal of a French summons and Edward’s renewal of the crown claim reveal that legal text did not settle allegiance and enforcement.

Key Characteristics

• Negotiated in 1360 after Edward III’s final invasion failed to secure coronation or Paris.
• Grants England a greatly expanded sovereign Aquitaine.
• Requires Edward to renounce his claim to the French crown.
• Builds on earlier Windsor terms while reducing maximal English demands.
• Vulnerable to fiscal, territorial, and appellate implementation disputes.
• Eventually repudiated when war resumes.

Evidence

• Negotiating turn: 321: Hundred Years’ War: A Storm of Swords (Part 4) links failed conquest and Lancaster’s warning to negotiations.
• Core exchange: 321: Hundred Years’ War: A Storm of Swords (Part 4) describes sovereign Aquitaine in exchange for renouncing the crown claim.
• Implementation strain: 321: Hundred Years’ War: A Storm of Swords (Part 4) connects damaged lands, taxation, and Aquitanian appeals to renewed conflict.
• Breakdown: 321: Hundred Years’ War: A Storm of Swords (Part 4) says Edward tears up the treaty and reclaims the French throne after Charles acts against English possessions.

Qualifications

The episode summarizes negotiations and implementation rather than parsing every clause, ratification step, territorial transfer, or later legal argument. The exact status of renunciations and appeals remains source-scoped.

What Changed

• Created the treaty profile as a strong settlement whose enforceability lagged behind its territorial design.

Relationships

• Edward III of England - English king receiving territory and renouncing the crown claim.
• John II of France - captive French king whose earlier terms shaped the settlement.
• Charles V of France - French ruler who later uses Aquitanian appeals to reopen the contest.
• Aquitaine - territorial core and implementation problem of the treaty.
• Feudal Homage Sovereignty Conflict - legal hierarchy the treaty tries, but fails, to settle durably.
• Battlefield Victory and Political Control - treaty demonstrates the difficulty of institutionalizing military gains.
