Hundred Years War

The Hundred Years War (1337-1453) was a series of conflicts between England and France over territory and the French throne; in AP Euro it matters as the backstory that weakened feudal nobles, strengthened national identity, and cleared the way for the centralized 'new monarchies' of Topic 1.5.

What is the Hundred Years War?

The Hundred Years War was a long, on-and-off fight between England and France lasting from 1337 to 1453. It started when English kings claimed the French throne and escalated into a struggle over French territory. England dominated early on (thanks partly to the longbow), but France rallied, famously behind Joan of Arc, and eventually pushed the English off the continent almost entirely.

Here's the AP Euro twist: the course officially starts around 1450, so the war itself is technically pre-course background. What you're actually responsible for is its aftermath. The war exhausted the old feudal nobility, taught monarchs how to raise national taxes and professional armies, and gave both English and French people a shared sense of 'us versus them.' Those are exactly the ingredients new monarchs like Louis XI of France and Henry VII of England used to build centralized states. Think of the Hundred Years War as the demolition crew that cleared the lot where the modern state got built.

Why the Hundred Years War matters in AP Euro

This term lives in Unit 1 (Renaissance and Exploration), specifically Topic 1.5, New Monarchies from 1450 to 1648. It supports learning objective AP Euro 1.5.A, explaining the causes and effects of political institutions from 1450 to 1648. The CED's essential knowledge (KC-1.5.I.A) says new monarchies built the foundation of the modern state by monopolizing tax collection, employing military force, and dispensing justice. The Hundred Years War is the 'cause' side of that cause-and-effect. Wartime taxation, royal armies replacing noble levies, and battered aristocracies are precisely what made those monopolies possible. If an exam question asks why centralized monarchies emerged around 1450, this war is your go-to context.

How the Hundred Years War connects across the course

Joan of Arc (Unit 1)

Joan rallied French forces at Orléans in 1429 and turned the war's momentum toward France. For AP purposes, she's a symbol of the rising national identity the war created, loyalty to 'France' itself rather than to a local feudal lord.

Longbow (Unit 1)

The English longbow mowed down French knights at battles like Crécy and Agincourt. That's not just military trivia. It shows armored noble cavalry becoming obsolete, which weakened the feudal aristocracy and made monarchs' professional armies the future.

Treaty of Picquigny (Unit 1)

In 1475, England's Edward IV invaded France one more time, and Louis XI simply paid him to go home. The treaty formally closed the book on English claims and shows the new-monarchy playbook in action, using royal cash and diplomacy instead of feudal warfare.

Concordat of Bologna (Unit 1)

The same French crown the war had strengthened kept centralizing into the 1500s. The 1516 Concordat gave the French king power to appoint bishops, extending royal control from taxes and armies into the church, just as KC-1.5.I.A describes.

Is the Hundred Years War on the AP Euro exam?

You won't be asked to narrate battles. The Hundred Years War shows up as context and causation. Multiple-choice stems pair it with a passage or map about state-building and ask what resulted from the war (centralized taxation, standing armies, national identity, weakened nobility). No released FRQ has used the term verbatim, but it's strong contextualization material. If a DBQ or LEQ asks about the rise of centralized states or new monarchies, opening with 'after the Hundred Years War devastated the feudal nobility and forced monarchs to develop national taxes and armies...' is exactly the kind of relevant context that earns the contextualization point. One trap to avoid is spending your essay on pre-1450 details. The exam wants the war's effects after 1450, not its medieval play-by-play.

The Hundred Years War vs Thirty Years' War

Easy to mix up because both names are just lengths of time, but they're two centuries and two units apart. The Hundred Years War (1337-1453) was England vs. France over territory and the throne, and it's Unit 1 background for new monarchies. The Thirty Years' War (1618-1648) was a religious-turned-political war centered in the Holy Roman Empire, ending with the Peace of Westphalia. Quick check on a question: dynastic claims and Joan of Arc mean Hundred Years; religion and Westphalia mean Thirty Years.

Key things to remember about the Hundred Years War

  • The Hundred Years War (1337-1453) was a series of conflicts between England and France over French territory and competing claims to the French throne.

  • AP Euro tests the war's effects, not its battles, because the course starts around 1450, right as the war ends.

  • The war weakened the feudal nobility and pushed monarchs toward national taxation and professional armies, the core features of new monarchies in KC-1.5.I.A.

  • Fighting a foreign enemy for over a century forged early national identities in both England and France, shifting loyalty from local lords to the crown.

  • Joan of Arc symbolizes the French national revival, and the longbow symbolizes the military decline of the feudal knight; both are shorthand for bigger structural changes.

  • Use the war as contextualization in any essay about the rise of centralized states between 1450 and 1648.

Frequently asked questions about the Hundred Years War

What was the Hundred Years War in AP Euro?

It was a series of wars between England and France from 1337 to 1453, fought over French territory and English claims to the French throne. In AP Euro it serves as the backdrop for Topic 1.5, since its aftermath produced the centralized new monarchies.

Is the Hundred Years War actually on the AP Euro exam?

Mostly as context, since the course begins around 1450 and the war ends in 1453. You won't be quizzed on battle dates, but you should be able to explain how the war's effects (weakened nobles, royal taxes, national armies) led to new monarchies under learning objective AP Euro 1.5.A.

How is the Hundred Years War different from the Thirty Years' War?

The Hundred Years War (1337-1453) was a dynastic and territorial fight between England and France. The Thirty Years' War (1618-1648) was a religious and political war centered in the Holy Roman Empire that ended with the Peace of Westphalia. They're separated by about 170 years and tested in completely different parts of the course.

Did the Hundred Years War actually last 100 years?

No, it lasted 116 years (1337-1453), and it wasn't one continuous war but a series of conflicts broken up by truces. The name is a later historians' label for the whole stretch of fighting.

How did the Hundred Years War lead to new monarchies?

It drained and discredited the feudal nobility, forced kings to create national taxation and professional armies, and built shared national identities. Rulers like Louis XI of France inherited those tools after 1453 and used them to centralize power, which is exactly what KC-1.5.I.A means by monopolies on taxes, military force, and justice.
