The Edwardian War was the early phase of the Hundred Years' War under Edward III of England, centered on his claim to the French throne and fights over French territory.
The Edwardian War is the first major phase of the Hundred Years' War in European History 1000 to 1500. It began in 1337, when Edward III of England pressed his claim to the French throne after the death of Charles IV, and France rejected that claim by backing Philip VI.
That succession dispute was not just a family argument. It sat on top of older tensions over land, trade, and political control. English kings still held territories in France, especially in the southwest, so the war mixed dynastic rivalry with a struggle over who really controlled those lands.
The conflict moved through a series of raids, naval clashes, and set-piece battles rather than one continuous campaign. One famous early English victory was the Battle of Crécy in 1346, where English archers using the longbow helped break traditional French attacks. That mattered because it showed that disciplined infantry and missile weapons could beat mounted nobles in the right terrain and formation.
The Edwardian War also damaged northern France badly. Armies lived off the land, towns and farms were disrupted, and civilians often paid the price even when they were not direct combatants. That pattern is one reason the war is more than a list of battles, it shows how medieval war could reshape society far from the royal courts.
This phase did not settle the dispute once and for all. Instead, it produced temporary truces, renewed fighting, and a longer Anglo-French rivalry that continued in later phases of the Hundred Years' War. If you see the term Edwardian War in this course, think of the opening round of that larger conflict, with Edward III’s claim, French resistance, and the shift in medieval warfare all tied together.
The Edwardian War matters because it shows how the Hundred Years' War began as both a dynastic crisis and a military turning point. In European History 1000 to 1500, that mix helps explain why medieval monarchies fought over inheritance, land, and prestige at the same time.
It also gives you a clear example of how warfare was changing. The longbow, stronger English tactical discipline, and the success at Crécy show that battlefield outcomes were no longer decided only by armored cavalry. That helps you track the broader shift from older feudal military habits toward more flexible forms of warfare.
The term also connects to the growth of centralization of power. Kings like Edward III were not just fighting for honor, they were trying to strengthen royal authority and claim larger political control. On essays or short-answer questions, you can use the Edwardian War to explain why England and France became more organized, more competitive, and more militarized in the late Middle Ages.

The Edwardian War is the opening phase of the Hundred Years' War, so it is not a separate conflict but part of the larger Anglo-French struggle. When you place it inside the longer war, you can see how the early fighting set patterns that continued later, including claims to the French crown, territorial raids, and repeated truces.
Edward III
Edward III is the central figure behind the Edwardian War because his claim to the French throne triggered the conflict. If a question asks why the war started, Edward III is the person you connect to dynastic ambition, royal legitimacy, and English intervention in French politics.
Battle of Crécy
Crécy is one of the best known examples of how the Edwardian War changed battlefield tactics. The English victory showed the power of longbowmen and defensive positioning against a larger French force, which makes it a useful case study for military innovation in the late Middle Ages.
Longbow
The longbow matters because it helped the English win battles like Crécy during the Edwardian War. In this period, it was not just a weapon, it changed how armies formed up and how cavalry charges fared, which is why it shows up in discussions of medieval warfare.
A timeline ID question may ask you to place the Edwardian War as the early phase of the Hundred Years' War, starting in 1337. In a short essay, you might use it to explain the causes of the wider Anglo-French conflict, especially Edward III's dynastic claim and the struggle over French territory. If a prompt gives you a battle description, look for clues like longbow use, English victories, or fighting on French soil and connect them back to this phase. On document or passage questions, it can show up as evidence of shifting military technology and the weakening of older feudal battle methods.
People often mix these up because the Edwardian War is part of the Hundred Years' War, not a separate conflict. Use Edwardian War when you mean the first major phase under Edward III, and use Hundred Years' War for the entire long conflict between England and France from 1337 to 1453.
The Edwardian War is the first major phase of the Hundred Years' War, beginning in 1337 under Edward III.
Its main cause was Edward III's claim to the French throne after Charles IV died without a direct male heir.
The war combined dynastic rivalry with territorial disputes, especially over English holdings in France.
Battles like Crécy show why the war mattered for military history, because longbows and tactics challenged older cavalry-based warfare.
The conflict caused major damage in northern France and led to truces that did not end the broader struggle.
The Edwardian War was the early phase of the Hundred Years' War, fought under Edward III of England beginning in 1337. It grew out of Edward's claim to the French throne and disputes over English-held lands in France. In this course, it shows how dynastic politics and military conflict were tied together in the late Middle Ages.
It started after Charles IV of France died in 1328 without a direct male heir, which opened a succession crisis. Edward III claimed the French crown through his mother, Isabella of France, but the French nobility rejected that claim and supported Philip VI instead. That political dispute turned into war over power, legitimacy, and territory.
It is not a different war, it is one phase of the larger Hundred Years' War. The Edwardian War refers to the earlier stage tied to Edward III, while the Hundred Years' War is the full conflict between England and France that lasted from 1337 to 1453. If a question asks about the whole war, use the broader term.
The Battle of Crécy is the clearest example because it shows English longbow tactics defeating a stronger French force. That battle is often used to explain why the Edwardian phase mattered militarily, not just politically. It also shows how the war affected French territory directly, since much of the fighting happened on French soil.
