The Hundred Years' War was not a single, continuous century of combat, but a series of intermittent conflicts between the English House of Plantagenet and the French House of Valois. Lasting 116 years from 1337 to 1453, the struggle fundamentally reshaped European borders, military technology, and national identities.
Despite its famous name, the Hundred Years' War actually spanned 116 years. The conflict began in 1337 when King Edward III of England challenged the legitimacy of King Philip VI of France and did not conclude until 1353, following the Battle of Castillon. The name is a historiographical shorthand coined centuries later to group these related dynastic struggles into a single narrative arc.
The Chronology of a Century-Plus Conflict
To understand why a 116-year war is called the "Hundred Years' War," one must look at the periods of intense fighting punctuated by long stretches of uneasy peace, plague, and internal rebellion. Historians generally divide this era into three primary phases, each marked by shifting fortunes and legendary figures.
The Edwardian Phase (1337–1360)
This initial period was defined by English naval and land victories. Edward III sought to reclaim the French throne through his mother, Isabella, the daughter of Philip IV of France. The English utilized the chevauchée—a scorched-earth raid designed to weaken the enemy's resources and provoke a response. Major English victories at the Battle of Crécy (1346) and the Battle of Poitiers (1356) saw the capture of King John II of France. This phase ended with the Treaty of Brétigny in 1360, where Edward III renounced his claim to the French throne in exchange for expanded territories in Aquitaine.
The Caroline Phase (1369–1389)
Peace was short-lived. Charles V of France, known as "the Wise," spent the decade following the treaty rebuilding French military strength and financial stability. He resumed the war in 1369. Unlike his predecessors, Charles V avoided large-scale pitched battles where the English longbow was most effective. Instead, he employed the brilliant constable Bertrand du Guesclin to conduct a war of attrition and siege. By the time a truce was signed in 1389, the English had been pushed back to a small coastal strip around Bordeaux and Calais.
The Lancastrian Phase (1415–1453)
After a long hiatus marked by the Black Death and internal strife in both kingdoms, Henry V of England renewed the claim to the French throne. His victory at the Battle of Agincourt in 1415 remains one of the most famous military upsets in history. The Treaty of Troyes (1420) initially appeared to hand France to the English, naming Henry V as heir to the French throne. However, the emergence of Joan of Arc in 1429 and the subsequent crowning of Charles VII at Reims turned the tide. The war effectively ended in 1453 when the French regained all English-held territories except for the Pale of Calais.
Why the Misnomer? Origins of the Name
The term "Hundred Years' War" (Guerre de Cent Ans) did not exist while the fighting was occurring. Soldiers and civilians in 1400 did not think of themselves as being in year 63 of a century-long struggle. They viewed the conflict as a series of separate wars regarding feudal rights and dynastic succession.
The name was popularized by French historians in the early 19th century. Specifically, Jean de Wavrin and later historians like François Guizot and Chrysanthe Des Michels began using the term in the 1820s and 1830s to provide a cohesive structure to French history textbooks. The name "Hundred Years" was catchy, memorable, and roughly accurate enough for general education, even if it lacked the mathematical precision of the actual 116-year duration.
In the context of 2026 scholarship, the name is retained more for convenience than for chronological accuracy. Modern historians acknowledge that the conflict was more of a "long 14th and 15th-century war" that integrated social upheavals, the Black Death, and the transition from feudalism to the early modern state.
The Dynastic and Feudal Roots
The conflict was born from the complex web of feudal obligations that tied the English monarchy to the French soil. Since the Norman Conquest of 1066, the Kings of England had held lands in France, making them vassals to the French King. This created an intolerable paradox: a sovereign king (of England) was required to pay homage to another king (of France) for his continental territories.
The Problem of Salic Law
When Charles IV of France died in 1328 without a male heir, the direct line of the House of Capet ended. Edward III of England, as Charles’s nephew, had a strong blood claim. However, the French nobility, wary of being ruled by an English king, invoked Salic Law. This ancient legal code was reinterpreted to assert that the throne could not be inherited through the female line. This allowed Philip VI of the House of Valois to take the throne, directly precipitating the declaration of war by Edward III.
The Importance of Aquitaine
While the throne was the grand prize, the immediate cause of friction was the Duchy of Aquitaine (Gascony). This region was a major economic powerhouse, particularly in the wine trade. The French kings repeatedly tried to encroach on English rights in the region, leading to legal disputes and eventually military action. For England, losing Aquitaine meant a massive loss of tax revenue; for France, having a foreign power control a significant portion of their coast was a strategic nightmare.
Technological and Tactical Evolution
The 116 years of conflict saw a total revolution in how wars were fought. At the start of the war in 1337, the armored knight was the undisputed master of the battlefield. By 1453, the rise of professional infantry and the introduction of gunpowder had rendered the traditional feudal knight nearly obsolete.
| Feature | Early War (1337) | Late War (1453) |
|---|---|---|
| Primary Weaponry | Swords, Lances, Crossbows | Longbows, Early Cannon, Handgonnes |
| Army Composition | Feudal Levies & Knights | Mercenary Companies & Standing Armies |
| Tactics | Heavy Cavalry Charges | Defensive Archery, Artillery Sieges |
| Armor | Chainmail with limited plate | Full Articulated Plate Armor |
| Fortifications | Stone Castles & Keeps | Earthworks & Cannon-resistant Walls |
The Dominance of the Longbow
The English longbow is perhaps the most iconic element of this era. Capable of firing up to 10-12 arrows per minute with enough force to penetrate standard mail, it allowed the English to win battles despite being frequently outnumbered. The victory at Agincourt, where a weary English force decimated the cream of French nobility, was largely attributed to the tactical deployment of longbowmen behind protective stakes.
The Rise of Artillery
While the longbow dominated the middle of the war, the closing stages belonged to the cannon. The French, under the guidance of the Bureau brothers, developed the most advanced artillery train in Europe. At the Battle of Castillon (1453), French cannons shredded English charges, effectively ending the war and proving that the era of the archer and the knight was yielding to the era of the gunner.
Societal and Economic Impact
The war was fought against the backdrop of the Black Death, which first arrived in Europe in 1347. The plague killed between 30% and 50% of the population, leading to massive labor shortages and social unrest.
The End of Feudalism
The high mortality rates from both the plague and the war gave surviving peasants more bargaining power. In England, this contributed to the Peasants' Revolt of 1381. In France, the Jacquerie of 1358 saw desperate rural populations rise against the nobility who failed to protect them from English raids. These events accelerated the decline of the feudal system, as monarchs began to rely on taxed-based professional armies rather than the traditional service of the landed gentry.
National Identity
Before the war, the English aristocracy spoke French, and "national" identity was secondary to feudal loyalty. By the end of the conflict, the two nations had distinct identities. The English began to champion the English language in law and literature (notably through Geoffrey Chaucer), while the French unified around the concept of the "sacred soil" of France, a sentiment galvanized by the martyrdom of Joan of Arc.

Why the "Hundred Years" Label Persists
In 2026, the term "Hundred Years' War" remains the standard designation in academic and popular history because it effectively encapsulates a specific geopolitical era. It marks the transition from the Middle Ages to the Renaissance. While the 116-year figure is the factual duration, the "Hundred Years" label serves as a symbolic marker for the long-term struggle between two burgeoning nation-states.
The war's conclusion in 1453 coincided with other world-changing events, most notably the Fall of Constantinople to the Ottoman Empire. Together, these events signaled the end of the medieval world order. The 116-year conflict wasn't just about land; it was the birth pains of modern France and England.
FAQs
Did the fighting happen every day for 116 years?
No. The war consisted of several "hot" periods of intense combat followed by years, or even decades, of truces, ceasefires, and stalemates. Some periods, like the years between 1389 and 1415, saw very little direct conflict between the two monarchies, although proxy wars and internal civil strife continued.
Who actually won the Hundred Years' War?
France is considered the ultimate victor. By 1453, the English had lost nearly all their continental possessions, including the prized Duchy of Aquitaine, which they had held for centuries. Although England retained Calais until 1558, they were forced to abandon their claim to the French throne in all but name.
What was the role of Joan of Arc?
Joan of Arc was a peasant girl who claimed divine guidance. She convinced the Dauphin (the future Charles VII) to let her lead a relief force to the besieged city of Orléans in 1429. Her success broke the English momentum and provided the French with the religious and nationalistic fervor needed to reclaim their territory.
How did the war change military history?
It marked the shift from heavy cavalry (knights) to disciplined infantry and the first significant use of gunpowder in European field battles. The English longbow forced a change in armor design, and the French development of a permanent standing army (compagnies d'ordonnance) set the stage for modern military structures.
Is the 116-year duration universally accepted?
Most historians agree on the 1337–1453 timeframe. However, some argue that the conflict was part of a much longer "Second Hundred Years' War" that lasted until the defeat of Napoleon in 1815, as England and France continued to clash globally for centuries.
Practical Recommendation for Further Study
For those looking to verify the specific legal and genealogical claims of the era, the British Library's medieval archives and the Archives Nationales of France provide digitized versions of the original treaties, including the Treaty of Brétigny and the Treaty of Troyes. Understanding these documents is essential for moving beyond the simplified "Hundred Years" narrative and appreciating the complex legal maneuvering that sustained the conflict for 116 years.
