Hundred Years' War

A long sequence of conflicts that transformed monarchy, warfare and identity in France and England.

Overview

The Hundred Years' War was a series of conflicts between English and French rulers from 1337 to 1453, interrupted by truces, plague and civil war. Claims to the French crown interacted with control of territory and aristocratic honour.

Military change mattered, but taxation, administration and political legitimacy determined whether victories could be sustained.

The essential guide

01

Dynastic claim and territory

Edward III claimed the French crown while defending lands and rights in France. Alliances with Flemish and French princes made the war more than a national duel.

02

Battlefield victories

English armies won at Crécy, Poitiers and Agincourt through position, discipline and circumstance. Victory did not guarantee control of territory.

03

French recovery

Joan of Arc helped restore Charles VII's momentum, while reforms in finance and artillery strengthened royal armies. Internal English weakness undermined occupation.

04

State and identity

War expanded taxation and representative bargaining. Later nationalism projected clearer English and French identities backward onto complex loyalties.
