Feudalism in AP World History: Modern
Feudalism was the political system of medieval Europe in which kings and great lords granted land, called fiefs, to vassals in exchange for military service and loyalty. Because many vassals ruled their own land, collected its revenue, and kept their own fighting men, power in Europe c. 1200-1450 was spread out among many nobles rather than concentrated in a central government.
This definition is part of Fiveable's AP World History: Modern review, which also has guided practice questions.
How Europe ended up running on land-for-loyalty deals
Feudal ties grew out of the breakdown of the Carolingian Empire in the 800s, when Viking and Magyar raids hit Western Europe and no central government could defend it. Local lords with armed horsemen filled that gap. Land was the main source of wealth, so land was what rulers had to offer in exchange for protection and soldiers.
By 1200, this arrangement was the normal way politics worked across much of Western Europe. Feudalism was a web of personal agreements that differed from region to region. There was never a single written code that applied everywhere.
The chain of obligations from king to knight
A lord granted a fief to a vassal, who swore an oath of loyalty (fealty) and promised to fight for the lord when called. Vassals could grant pieces of their own land to lesser vassals, such as knights, creating layers of obligation below the king.
The complication is that loyalty ran person to person, so the chain could tangle. A noble might hold land from more than one lord. English kings held lands in France as vassals of the French king, which helped set up conflicts like the Hundred Years' War (1337-1453).
At the bottom were peasants, many of them serfs bound to the land, who did the farming that fed the whole system. Their side of things is manorialism, the economic system of the self-sufficient estate. Feudalism describes relationships among the people who held power. Manorialism describes how peasants worked a lord's estate in return for protection. If a question is about oaths, knights, and nobles, it's asking about feudalism. If it's about crops, labor dues, and life on an estate, it's asking about manorialism. Topic 1.6 lists both as defining features of Europe, along with the idea that European farming relied on free and coerced labor, including serfdom.
Why royal power was limited
This is the cause-and-effect point the course is after. Topic 1.6, Europe from 1200 to 1450, asks you to explain why political power in Europe was decentralized during Unit 1 (1200-1450). Several things fed into that. Rulers had granted land and rights, sometimes including the right to hold courts or collect revenue, to nobles. Those nobles owed their lords military service and other obligations, and many of them were powerful local figures with their own armed followers.
The balance of power wasn't the same everywhere. Kings could reach beyond their own lands through royal officials, royal courts, and taxes, and some monarchies were much stronger than others. Still, in many places a king had to work with, and sometimes against, nobles who controlled land and fighting men.
A multiple-choice question might ask how obligations between lords and vassals contributed to political fragmentation. Use the source and answer choices to determine the best answer. Keep the political lord-vassal tie separate from the peasant labor system, since mixing them up is an easy mistake.
The Magna Carta (1215) makes a good piece of supporting evidence. English barons forced King John to accept limits on his power, which shows how much strength nobles could hold against a monarch.
Setting feudal Europe against Song China's bureaucracy
Topic 1.7 asks you to compare how states formed in different regions from 1200 to 1450. The standard contrast is with the Song Dynasty, which kept power through Confucianism and an imperial bureaucracy staffed by officials chosen through civil service exams. Song officials were appointed and paid by the state. European vassals held power largely because they held land.
The comparison fits several written question types. In the Long Essay Question, a comparison prompt on state building lets you use feudal Europe and Song China as your two cases. A strong thesis explains why the systems differed. Saying one was centralized and the other wasn't is only a starting point. In a Short-Answer Question with a source about medieval government, you might be asked to identify a similarity or difference, and naming feudal loyalty oaths versus an exam-based bureaucracy gives the specific evidence the question needs.
Japan works as a second comparison, since samurai served lords in exchange for land or income under a military government. If you use it, point out that Japan also had decentralized military power. That makes it a similarity case where Song China is a difference case.
What wore feudal ties down after 1300
The Black Death (1347-1351) killed a huge share of Europe's population. With fewer workers, surviving peasants could demand better terms, and serfdom weakened in Western Europe over the following century.
Warfare changed too. Paid soldiers, longbowmen, and eventually gunpowder weapons cut into the value of mounted knights, so the military reason for granting fiefs faded. Monarchs who could collect taxes and pay armies directly began pulling power back from nobles. That sets up later units, where stronger, more centralized European monarchies build armies and overseas empires after 1450. If a later question asks about state centralization in Europe, feudalism is the earlier system that centralization replaced.
