Treaty of Troyes

Overview

The Treaty of Troyes is the 1420 agreement that kept Charles VI as king but made Henry V regent and heir to France.

Current Profile

The settlement arose from English conquest and Burgundian alignment after Montereau. Henry’s marriage to Catherine of Valois supplied its dynastic mechanism, while the Dauphin Charles was effectively disinherited.

Its governing design was an Anglo-French Dual Monarchy: England and France would remain separate kingdoms under one crown. Continued Dauphinist resistance and Henry’s death before Charles VI made the agreement dependent on an infant heir and exposed its fragility.

Key Characteristics

• Ratified on 21 May 1420 after English-Burgundian negotiations.
• Preserved Charles VI’s title during his lifetime.
• Made Henry regent and successor to the French crown.
• Joined succession to Henry’s marriage with Catherine.
• Excluded the Dauphin Charles from inheritance.
• Designed separate kingdoms under one crown rather than formal annexation.

Evidence

• Political preconditions: 490. Hundred Years’ War: England Triumphant (Part 4) links the treaty to conquest, Montereau, and Philip the Good’s alignment.
• Constitutional terms: 490. Hundred Years’ War: England Triumphant (Part 4) specifies kingship, regency, marriage, inheritance, and disinheritance.
• Fragility: 490. Hundred Years’ War: England Triumphant (Part 4) records continued resistance and Henry’s death with a nine-month-old son.

Qualifications

The episode presents the treaty as Henry’s extraordinary high point without treating it as a settled peace. Its legitimacy remained disputed, and the source ends before testing its longer-term institutional viability.

What Changed

• Created Troyes as the constitutional mechanism translating conquest and alliance into a disputed dynastic succession.

Relationships

• Charles VI of France - reigning king retained under the settlement.
• Charles VII of France - Dauphin excluded from succession.
• Catherine of Valois - bride whose marriage anchored the new dynastic line.
