The Origins of a Century-Long Conflict
At the heart of the Hundred Years' War lay a complex web of succession crises and territorial ambitions. The conflict between England and France was not merely a matter of military might but was deeply rooted in dynastic claims and economic interests.
Dynastic Claims to the French Throne
The dispute over the French throne was a significant catalyst for the war. Edward III of England claimed the French throne through his maternal lineage, challenging the French succession laws.
Edward III's Maternal Lineage
Edward III's mother, Isabella of France, was the daughter of Philip IV of France, providing Edward with a direct lineage to the French throne. This familial connection was a crucial argument in his claim.
Salic Law and Succession Disputes
The French, however, invoked the Salic Law, a legal code that prohibited succession through the female line. This law effectively barred Edward III from the throne, leading to a significant succession dispute.
The Confiscation of Gascony
Another critical factor was the confiscation of Gascony by Philip VI of France. Gascony was an English territory in southwestern France, and its confiscation had significant economic implications.
Economic Importance of the Region
Gascony was crucial for the English economy, particularly due to its wine production. The loss of this territory threatened English economic interests and contributed to the tensions leading to the Hundred Years' War.
Desmond Seward once noted, "The Hundred Years War was as much a civil war as a national conflict."
This observation highlights the complex nature of the conflict, involving both dynastic and territorial disputes.
Key Players Who Shaped the War
The Hundred Years' War was a complex conflict influenced by various individuals with distinct ambitions and strategies. The war was shaped by the interactions and decisions of several key players, whose actions had significant impacts on its progression and outcome.
Edward III and His Ambitious Vision
Edward III of England played a pivotal role in initiating the Hundred Years' War. His claim to the French throne was not merely a dynastic ambition but a strategic move to expand English territories and influence. Edward III's military campaigns and diplomatic maneuvers set the stage for the prolonged conflict.
Philip VI and the Valois Dynasty
Philip VI, the first king of the Valois dynasty, faced the challenge of defending the French throne against Edward III's claims. His reign was marked by efforts to consolidate power and resist English aggression, setting the tone for the Valois dynasty's stance during the war.

The Black Prince: England's Warrior Hero
The Black Prince, Edward III's eldest son, was a renowned military leader whose victories, particularly at the Battle of Crécy and the Battle of Poitiers, were crucial to English successes during the war. His military prowess and chivalric reputation made him a legendary figure.
Charles V the Wise: France's Strategic Genius
Charles V, who ruled France from 1364 to 1380, is remembered for his strategic genius. He implemented significant military and financial reforms, leveraging the work of constable Bertrand du Guesclin to turn the tide of the war in favor of the French. His reign marked a turning point in the conflict.
Key Player | Role | Impact |
---|---|---|
Edward III | King of England | Initiated the war with his claim to the French throne |
Philip VI | King of France | Defended the French throne against Edward III's claims |
The Black Prince | English Military Leader | Secured crucial victories for the English |
Charles V | King of France | Implemented reforms that turned the war in France's favor |
The First Phase: Edwardian War (1337-1360)
The year 1337 saw the outbreak of the Edwardian War, the first major phase of the Hundred Years' War. This period was marked by significant English victories that showcased their military prowess, particularly the use of the English longbow.
The Naval Battle of Sluys: Control of the Channel
The Edwardian War began with a decisive naval victory for the English at the Battle of Sluys in 1340. This battle gave England control over the English Channel, facilitating further military campaigns in France.
The Battle of Crécy and English Longbows
The Battle of Crécy in 1346 was a landmark English victory, largely due to the effectiveness of the English longbow. The longbow's range and firepower outclassed the French knights, demonstrating a significant shift in medieval warfare tactics.
The Siege of Calais: A Foothold in France
Following Crécy, the English successfully besieged Calais, capturing the city in 1347. This provided England with a crucial foothold in France, which remained under English control for over two centuries.
The Black Death's Devastating Impact
The Black Death, which struck Europe in the late 1340s, had a profound impact on both England and France, decimating populations and affecting the course of the war. The pandemic led to significant social and economic changes, influencing the progression of the conflict.
The Treaty of Brétigny: A False Peace
After decades of conflict, the Treaty of Brétigny emerged as a significant, albeit temporary, peace agreement between England and France in 1360. This treaty was a landmark moment in the Hundred Years' War, marking a brief period of respite from the violence that had ravaged both countries.
Terms and Territorial Exchanges
The Treaty of Brétigny was notable for its territorial adjustments. England gained significant territories in France, including Calais, Gascony, and other regions, in exchange for renouncing its claim to the French throne. This exchange was seen as a major concession by the English, but it ultimately proved to be a temporary measure.
The treaty's terms also involved substantial territorial exchanges, with the English securing control over several key French territories. However, the agreement's complexity and the challenges of implementing these territorial changes contributed to future tensions.
King John II's Ransom and Captivity
One of the treaty's most significant provisions was the agreement to release King John II of France from English captivity in exchange for a substantial ransom. King John II had been captured by the English at the Battle of Poitiers in 1356 and was being held prisoner.
The ransom was set at three million gold écus, a staggering amount that placed a heavy burden on the French economy. The payment of this ransom was to be made in installments, but it was not completed as agreed, leading to further complications.
Why the Peace Collapsed So Quickly
Despite the initial optimism surrounding the Treaty of Brétigny, the peace it established was short-lived. Several factors contributed to its collapse, including disagreements over the treaty's terms and the failure to complete King John II's ransom payments.
Reasons for Collapse | Description | Impact |
---|---|---|
Disagreements over Treaty Terms | The complexity and ambiguity of the treaty's terms led to differing interpretations by the English and French. | Renewed Tensions |
Failure to Complete Ransom Payments | The French struggled to pay the ransom for King John II, leading to a breach of the treaty's conditions. | Increased Hostility |
Territorial Disputes | The territorial exchanges agreed upon in the treaty were not fully implemented, causing further conflict. | Escalation of War |
The Treaty of Brétigny ultimately failed to bring lasting peace, and its collapse marked the beginning of another phase of the Hundred Years' War. Understanding the reasons behind its failure provides valuable insights into the complexities of medieval diplomacy and conflict resolution.

The Caroline Phase: French Resurgence (1369-1389)
Charles V's strategic reforms characterized the Caroline Phase of the Hundred Years' War, marking a period of significant French resurgence. This era, spanning from 1369 to 1389, was defined by Charles V's military and financial reforms, which laid the groundwork for France's recovery.
The reforms implemented by Charles V were multifaceted, aiming to strengthen the French military and economy. One of the key aspects was the reorganization of the military, making it more efficient and effective. This period also saw the rise of Bertrand du Guesclin, a renowned military leader who employed guerrilla warfare tactics to great success.
Charles V's Military and Financial Reforms
Charles V's reforms were pivotal in turning the tide of the war in favor of France. He focused on rebuilding the French army, improving its discipline, and enhancing its tactical capabilities. Financial reforms were also crucial, as they ensured a steady supply of funds to support the military efforts.
Bertrand du Guesclin's Guerrilla Warfare
Bertrand du Guesclin's adoption of guerrilla warfare tactics was a game-changer. By avoiding direct confrontations and employing hit-and-run strategies, du Guesclin was able to weaken the English forces significantly. His tactics not only drained English resources but also boosted French morale.
English Losses and Territorial Shrinkage
The Caroline Phase saw substantial English losses and a significant shrinkage of their territories in France. The effective French strategies under Charles V and du Guesclin led to the recapture of several key territories.
Territory | Status Before Caroline Phase | Status After Caroline Phase |
---|---|---|
Poitiers | Under English Control | Recaptured by France |
La Rochelle | Under English Influence | Regained by France |
Bordeaux | English Territory | Remained Under English Control |
Normandy | Partial English Control | Largely Freed from English Influence |
The Caroline Phase was a critical period in the Hundred Years' War, marking a significant shift in favor of the French. The strategic leadership of Charles V and the military prowess of Bertrand du Guesclin were instrumental in this French resurgence.
