The Hundred Years War (1337-1453) was a series of intermittent conflicts between England and France over claims to the French throne; on the AP World exam it illustrates Europe's political decentralization in Topic 1.6 and the slow shift from feudal armies toward centralized monarchies and national identity.
The Hundred Years War was a drawn-out, on-and-off conflict between England and France from 1337 to 1453, sparked when English kings claimed the right to the French throne. It wasn't one continuous war. Think of it as a 116-year rivalry made up of campaigns, truces, and flare-ups, with famous moments like the English longbow victory at Agincourt (1415) and Joan of Arc rallying French forces in the war's final phase.
For AP World, the war matters less as a list of battles and more as evidence of what Europe looked like from 1200 to 1450. Europe was politically fragmented, built on feudalism and decentralized monarchies, and this war exposed the weaknesses of that system. Feudal knights got cut down by paid commoners with longbows, kings started relying on taxes and professional soldiers instead of vassals, and ordinary people in both kingdoms began thinking of themselves as 'English' or 'French' rather than just subjects of a local lord. The war is basically feudalism's stress test, and feudalism failed it.
The Hundred Years War lives in Topic 1.6 (Developments in Europe from 1200-1450) within Unit 1: The Global Tapestry. It directly supports learning objective AP World 1.6.B, which asks you to explain the causes and consequences of political decentralization in Europe. The war is your best concrete example of that decentralization in action and of the forces starting to reverse it. England and France entered the war as feudal patchworks where kings depended on nobles for armies. They came out of it with stronger royal taxation, more professional militaries, and early national identities. That makes the war a perfect 'turning point' example for the Governance theme, and it sets up the centralized European states you'll see flexing maritime power in Units 3 and 4. If you can explain why a feudal lord mattered less in 1453 than in 1337, you understand the consequence the CED is after.

Feudalism (Unit 1)
Feudalism is the system the war broke. Kings who once depended on noble vassals for knights shifted to taxed, paid armies, which made monarchs stronger and lords weaker. The Hundred Years War is the go-to example for explaining how decentralized European monarchies started centralizing.
Black Death (Unit 1)
The plague hit Europe in the late 1340s, right in the middle of the war, killing 30-50% of the population. The two crises stacked on each other. Labor shortages weakened serfdom and the manorial system while the war weakened the nobility, so feudal Europe got squeezed from both ends.
Joan of Arc (Unit 1)
Joan is the war's most testable figure. A peasant girl claiming divine visions led French troops to victory, which shows you two CED ideas at once. Christianity still shaped European society (1.6.A), and a shared 'French' identity was forming around the monarchy and the war effort.
Battle of Agincourt (Unit 1)
Agincourt (1415) is the war's signature battle and the clearest snapshot of military change. English longbowmen, mostly commoners, shredded armored French knights. When cheap missile weapons beat expensive aristocratic cavalry, the social logic behind the knightly class started to crumble.
You won't be asked to recite battle dates. Multiple-choice questions use the Hundred Years War as evidence for Topic 1.6 claims, usually paired with a passage or image, asking what the war reveals about political decentralization, the decline of feudal warfare, or the rise of national identity in England and France. Practice questions hit exactly these angles, asking how the war reshaped the political landscape of both kingdoms and how it transformed the identity and consciousness of their peoples. Joan of Arc also shows up in comparison questions about women's roles in European history. No released FRQ has used the term verbatim, but it's strong evidence for an LEQ or DBQ about state-building or continuity and change in Europe from 1200 to 1450. The move you need to make is connecting the war to a bigger process, like 'the Hundred Years War accelerated centralization because monarchs replaced feudal levies with taxed professional armies,' rather than just name-dropping it.
The names sound like siblings but they're different wars in different periods. The Hundred Years War (1337-1453) was a dynastic fight between England and France over the French throne, and it belongs to Unit 1's medieval, feudal Europe. The Thirty Years' War (1618-1648) was a largely religious conflict in the Holy Roman Empire after the Protestant Reformation, centuries later. Quick check for the exam: throne dispute plus knights and longbows means Hundred Years War; Catholics versus Protestants in central Europe means Thirty Years' War.
The Hundred Years War (1337-1453) was a series of conflicts between England and France triggered by English claims to the French throne.
On the AP exam, the war is evidence for AP World 1.6.B because it shows both Europe's political decentralization and the forces that began centralizing power in monarchs.
Military changes like the English longbow at Agincourt made feudal knights obsolete and pushed kings toward paid, professional armies funded by royal taxation.
The war helped create early national identities, with people increasingly seeing themselves as English or French rather than just subjects of a local lord.
Joan of Arc connects the war to religion in Topic 1.6, since her claimed divine visions show how Christianity continued to shape European society and politics.
The Black Death struck mid-war and compounded its effects, so feudalism and serfdom were weakened by plague-driven labor shortages and war-driven political change at the same time.
It was a series of conflicts between England and France from 1337 to 1453, fought over English claims to the French throne. In AP World it appears in Topic 1.6 as an example of European political decentralization and the early shift toward centralized monarchies and national identity.
No, it lasted 116 years (1337-1453), and it wasn't continuous fighting. It was a string of campaigns broken up by truces and peace periods, which is why it's described as a series of conflicts rather than one long war.
The Crusades were religious wars launched by European Christians, mostly aimed at the Holy Land, starting in the late 1000s. The Hundred Years War was a dynastic and political fight between two Christian kingdoms over who should rule France. Religion drove the Crusades; succession and territory drove the Hundred Years War.
It's your concrete evidence for learning objective AP World 1.6.B on the causes and consequences of political decentralization in Europe. The war weakened feudal nobles, strengthened royal taxation and professional armies, and helped build English and French national identities.
France did, by 1453, driving the English out of nearly all their French territory, with Joan of Arc's victories helping turn the tide in the final phase. For the exam, though, the bigger point is that monarchs in both kingdoms came out stronger relative to their feudal nobles.
