AP European History Unit 3 ReviewAbsolutism and Constitutionalism

AP Euro Unit 3 covers how European states built and organized political power between 1648 and 1815, after the Peace of Westphalia made the sovereign state the basic unit of European politics. The big idea is that monarchs and elites fought over who held sovereignty, and that struggle produced two competing models. France and Russia centralized power in the monarch (absolutism), while England and the Dutch Republic limited rulers through law and representative institutions (constitutionalism). The unit also tracks the economic engine behind state power, including mercantilism, the Agricultural Revolution, and the transatlantic slave-labor system.

What this unit covers

The Westphalian world and the fight over sovereignty

• The Peace of Westphalia (1648) ended the Thirty Years' War and established the sovereign state. After 1648, rulers controlled what happened inside their borders, and religion faded as the main reason states went to war.
• Secular systems of law replaced religious justifications as the basis for new political institutions. Politics started running on state interest, not confessional loyalty.
• Inside each state, monarchs competed with nobles, churches, town governments, and regional assemblies over how much power the crown actually held. Different outcomes of that fight explain why France looks nothing like England by 1700.

Absolutism in action

• Louis XIV of France is the model. He and his finance minister Jean-Baptiste Colbert extended the central state's administrative, financial, military, and religious control over the French population. Versailles turned the nobility into courtiers who competed for the king's attention instead of plotting against him.
• Absolute monarchs limited the nobility's role in governing but preserved aristocratic social status and legal privileges. That trade is the core mechanism. Nobles gave up political power and kept their tax exemptions and titles.
• Peter the Great "westernized" Russia, reshaping political, religious, and cultural institutions to look more like Western Europe. Catherine the Great continued strengthening central authority later in the period.
• The Hohenzollerns built Prussia into a militarized, centralized state where the army and bureaucracy were the backbone of royal power.

Constitutionalism in England and the Dutch Republic

• The English Civil War (1642-1651) was a fight among the monarchy, Parliament, and other elites over their roles in the political structure. Charles I lost his head; England briefly became a republic under Cromwell.
• The Glorious Revolution (1688) settled the question. James II was replaced by William and Mary, who accepted the English Bill of Rights (1689). The result was a constitutional monarchy where Parliament, not the king, held ultimate authority.
• The Dutch Republic, born from a Protestant revolt against the Habsburg monarchy, developed an oligarchy of urban gentry and rural landholders who governed to promote trade and protect traditional rights. It became the commercial and financial center of 17th-century Europe (the Dutch Golden Age).

The economic engine: mercantilism, agriculture, and global trade

• Mercantilism treated wealth as a zero-sum competition. States drew resources from New World colonies, hoarded bullion, and protected domestic industry. Colbert's policies in France are the textbook example.
• The transatlantic slave-labor system expanded in the 17th and 18th centuries as European demand for New World products like sugar grew.
• The Agricultural Revolution raised productivity and increased the food supply, helped along by crops imported from the Americas. More food meant population growth and labor freed up for other work.
• The putting-out system (cottage industry) moved manufacturing into rural households, and labor and trade were increasingly freed from traditional guild and government restrictions. Overseas products fueled a consumer revolution in Europe.

Balance of power, diplomacy, and the military revolution

• After Westphalia, the balance of power structured diplomacy and warfare. The goal was to prevent any single state (usually France) from controlling the continent.
• The military revolution changed who could compete. Greater reliance on infantry, firearms, mobile cannon, and elaborate fortifications required heavier taxation and larger bureaucracies. States that could fund the new warfare (France, Prussia, Russia, Britain) pulled ahead.
• Poland is the cautionary tale. The Polish monarchy could not consolidate authority over its nobility, so Prussia, Russia, and Austria partitioned it out of existence by 1795. Weak central power meant elimination from the map.

Unit 3, Absolutism and Constitutionalism at a glance

Why Unit 3, Absolutism and Constitutionalism matters in AP Euro

This unit answers one of the course's central questions, which is how states acquire and organize power. The absolutism-versus-constitutionalism comparison is the single most common comparison setup in the entire course, and the economic story here (mercantilism, slavery, the Agricultural Revolution) is the launching pad for everything industrial and imperial that follows.

• The sovereign state and balance-of-power diplomacy created here are the operating system of European politics through 1914. Every later war and peace settlement runs on Westphalian logic.
• The contrast between centralized and limited government sets up the political debates of the Enlightenment, the French Revolution, and 19th-century liberalism.
• Mercantilism and the global economic network explain where Europe's capital came from, which you need to explain industrialization.

How this unit connects across the course

• The religious wars and Habsburg conflicts from the Reformation era (Unit 2) are the backstory. Westphalia ends that world, and Unit 3 explains what replaced it.
• Colonial wealth from the Age of Exploration (Unit 1) is what mercantilist states are competing over. Unit 3 shows the system Europe built to extract and manage it.
• Locke's justification of the Glorious Revolution and Enlightenment critiques of absolutism (Unit 4) grow directly out of this unit's political experiments.
• Louis XIV's expensive wars and the absolutist tax system create the French fiscal crisis that detonates in the French Revolution (Unit 5), and the Agricultural Revolution plus the putting-out system are the preconditions for industrialization (Unit 6).

Timeline

• 1642-1651: The English Civil War pits Charles I against Parliament over who controls taxation, religion, and the army. Charles I is executed in 1649, proving a king could be held accountable.
• 1648: The Peace of Westphalia ends the Thirty Years' War, establishes state sovereignty, and pushes religion out of the center of European diplomacy.
• 1643-1715: The reign of Louis XIV, the longest in European history, defines absolutism through Versailles, Colbert's mercantilism, and near-constant warfare.
• 1685: Louis XIV revokes the Edict of Nantes, ending toleration for French Protestants and showing religious control as a tool of absolutist state-building.
• 1688-1689: The Glorious Revolution replaces James II with William and Mary, and the English Bill of Rights locks in parliamentary supremacy and limited monarchy.
• 1682-1725: Peter the Great westernizes Russia, building St. Petersburg, reorganizing the church and army, and forcing the nobility into state service.
• 1700s: The military revolution matures. States that can tax heavily and run large bureaucracies (Prussia, Russia, Britain, France) outcompete those that cannot.
• 1772-1795: Prussia, Russia, and Austria partition Poland in three stages, erasing a major state whose monarchy never controlled its nobility.

Key people and groups

• Louis XIV: The "Sun King" of France, the definitive absolute monarch who centralized administration, religion, and the military under the crown.
• Jean-Baptiste Colbert: Louis XIV's finance minister and the architect of French mercantilism, building state-sponsored industry and colonial trade.
• Charles I: English king whose clashes with Parliament over money and power triggered the English Civil War; executed in 1649.
• Oliver Cromwell: Parliamentary commander who ruled England as Lord Protector after the civil war, a republican experiment that didn't outlast him.
• William and Mary: Co-monarchs invited to take the English throne in 1688 who accepted the Bill of Rights, sealing constitutional monarchy.
• James II: Catholic English king whose policies alarmed Parliament and provoked the Glorious Revolution.
• Peter the Great: Russian tsar who forcibly westernized Russia's political, religious, and cultural institutions.
• Catherine the Great: Russian empress who continued centralizing state power later in the period.
• The Hohenzollerns: Prussia's ruling dynasty, builders of a militarized absolutist state punching above its size.
• Dutch urban gentry: The merchant oligarchy that governed the Dutch Republic to promote trade and protect traditional rights.

Unit 3, Absolutism and Constitutionalism on the AP exam

This unit is built for the comparison skill. Expect prompts asking you to compare absolutist and constitutional states, usually France or Russia against England or the Dutch Republic, in multiple-choice sets, short-answer questions, and long essays. Continuity-and-change prompts also love this unit's economics, asking how commercial practices changed (mercantilism, the slave trade, cottage industry) versus what stayed the same from 1648 to 1815.

• Document-based and stimulus questions often hand you a royal decree, a political treatise, or an image of Versailles and ask you to analyze its purpose, audience, or point of view. Think about why Louis XIV would want nobles living at court, or why Parliament framed the Bill of Rights the way it did.
• Causation questions target the English Civil War and Glorious Revolution. Be ready to explain both causes (monarch versus Parliament over taxation and religion) and consequences (parliamentary sovereignty, a model for limited government).
• Contextualization points are easy to earn here if you can place a document in the post-Westphalia world of sovereign states and balance-of-power competition.

Essential questions

• Why did some European states centralize power in the monarch while others developed limits on royal authority?
• How did the Peace of Westphalia change the way European states related to each other and justified war?
• How did mercantilism, colonial extraction, and the slave-labor system fuel European state power?
• What happened to states, like Poland, that failed to build effective central authority?

Key terms to know

• Absolutism: A system where the monarch holds supreme authority, unrestrained by representative bodies or legal checks.
• Constitutionalism: A system where the ruler's power is limited by law and shared with representative institutions.
• Sovereignty: A state's supreme authority over its own territory and internal affairs, the core principle established at Westphalia.
• Divine right of kings: The claim that monarchs get their authority directly from God and answer only to Him.
• Mercantilism: The economic theory that national power depends on accumulating wealth, so the state should control trade and extract resources from colonies.
• Balance of power: The diplomatic principle that no single state should be allowed to gain enough strength to control Europe.
• Military revolution: The shift to infantry, firearms, mobile cannon, and fortifications that forced states to raise taxes and build bureaucracies to compete.
• Putting-out system: Cottage industry where merchants supplied raw materials to rural households that produced goods at home, bypassing urban guilds.
• Agricultural Revolution: Improvements in farming productivity that increased food supply and supported population growth.
• English Bill of Rights: The 1689 settlement that limited royal power and guaranteed parliamentary authority after the Glorious Revolution.
• Parliamentary sovereignty: The principle that the legislature, not the monarch, holds final authority in the state.
• Versailles: Louis XIV's palace, used to control the nobility by pulling them into elaborate court ritual and away from independent power.
• Partition of Poland: The division of Poland among Prussia, Russia, and Austria, completed in 1795, after its monarchy failed to control the nobility.

Common mix-ups

• The English Civil War and the Glorious Revolution are two different events. The civil war (1642-1651) was bloody and ended with a king's execution and a failed republic. The Glorious Revolution (1688) was nearly bloodless and produced the lasting constitutional settlement.
• Absolutism did not abolish the nobility. Monarchs cut nobles out of governing but protected their social rank and legal privileges. That bargain is exactly what the exam wants you to explain.
• The Dutch Republic was constitutional but not democratic. It was an oligarchy run by wealthy urban gentry and landholders, not a government elected by ordinary people.
• Westphalia reduced religion as a cause of war between states, but it did not end religious policy inside states. Louis XIV revoking the Edict of Nantes in 1685 shows monarchs still used religious uniformity as a tool of control.
