Mercantilism is the economic theory, dominant in Europe from the 16th to 18th centuries, that a nation's power comes from its wealth (especially gold and silver), so the state should regulate trade to export more than it imports and use colonies as sources of raw materials and captive markets.
Mercantilism is the idea that the world's wealth is a fixed pie, so the only way for a nation to get richer is to grab a bigger slice than its rivals. In practice, that meant European states stockpiled gold and silver, pushed for a favorable balance of trade (exporting more than they imported), and treated colonies as economic tools. Colonies shipped cheap raw materials to the mother country, and the mother country sold finished goods back, often banning the colonies from trading with anyone else.
The key thing for AP World is that mercantilism is state-driven. Governments did not stay out of the economy; they sponsored exploration voyages, chartered joint-stock companies, and wrote laws controlling who their colonies could trade with. This is the economic logic behind the maritime empires of Unit 4. Spain extracting silver from the Americas, Portugal building a trading-post empire, and England, France, and the Dutch racing across the Atlantic all make sense once you see them as states competing for a bigger slice of that fixed pie.
Mercantilism lives mainly in Unit 4 (Transoceanic Interconnections, 1450-1750), where it explains why states funded exploration in the first place. Learning objective AP World 4.2.A asks you to describe the role of states in maritime exploration, and 4.2.B asks for the economic causes and effects of that exploration. Mercantilism is the answer to both. Monarchs paid for caravels and Columbus because they believed overseas wealth equaled national power. It also connects to 4.8.A, since mercantilist trade reshaped social structures across both hemispheres.
Then it matters again in Unit 5, but as the thing that ends. Under learning objective AP World 5.7.A, you need to explain how Western European countries abandoned mercantilism for free trade as Adam Smith's laissez-faire capitalism caught on after 1750. That makes mercantilism a perfect continuity-and-change anchor across two units, which is exactly the kind of cross-period thinking essays reward.

Adam Smith and Laissez-Faire Capitalism (Unit 5)
Smith's Wealth of Nations (1776) argued the opposite of mercantilism. Wealth is not a fixed pie of gold; free trade can grow the pie for everyone. The CED explicitly says Western Europe abandoned mercantilism for free trade in the 1750-1900 period, so know mercantilism as the 'before' picture and laissez-faire as the 'after.'
State-Sponsored Maritime Exploration (Unit 4)
Mercantilism explains the 'why' behind Topic 4.2. Portugal's trading-post empire, Spain's sponsorship of Columbus, and English, French, and Dutch Atlantic crossings were all state investments aimed at capturing trade wealth before a rival did.
Colonies and Cash Crops (Unit 4)
Under mercantilism, a colony exists to serve the mother country. It grows cash crops like sugar and tobacco, ships raw materials home, and buys finished goods back. This one-way relationship is the engine behind plantation economies and the Atlantic system.
Atlantic Slave Trade (Unit 4)
Mercantilist plantation colonies demanded massive coerced labor, which fueled the Atlantic slave trade. When an exam question asks how economic developments affected social structures (4.8.A), this is the dot to connect.
Multiple-choice questions usually test mercantilism through cause and effect. Expect stems asking what economic system emerged from European exploration, how mercantilist policies shaped the relationship between mother countries and colonies, or how those policies created an early form of global economic integration. The answer pattern is consistent. States regulate trade, colonies supply raw materials and buy finished goods, and rival powers compete for bullion and markets.
No released FRQ has used the term verbatim, but mercantilism is high-value evidence for essays. It works as causation evidence for why states sponsored exploration (Unit 4), and it is a textbook change-over-time move in a Unit 5 essay, since you can argue Europe shifted from state-controlled mercantilism to free-market capitalism after Adam Smith. If a DBQ touches on early modern empires or industrial-era economics, mercantilism is contextualization gold.
Both are about trade and profit, but they disagree on the government's job. Mercantilism says the state should control trade because wealth is a fixed pile of gold to fight over. Laissez-faire capitalism, pushed by Adam Smith after 1776, says the government should step back because free markets create new wealth. On the AP exam, mercantilism dominates 1450-1750 and gets abandoned for free trade in the 1750-1900 period.
Mercantilism is the theory that national power comes from accumulating wealth, especially gold and silver, through a favorable balance of trade where exports exceed imports.
Mercantilism treats colonies as tools that supply cheap raw materials to the mother country and serve as a captive market for its finished goods.
Mercantilism explains why European states sponsored maritime exploration from 1450 to 1750, which is exactly what learning objectives 4.2.A and 4.2.B ask about.
Under mercantilism, governments actively regulated the economy, the opposite of the laissez-faire approach that replaced it.
Western European countries abandoned mercantilism for free trade between 1750 and 1900 as Adam Smith's ideas spread, a major change tested under learning objective 5.7.A.
Mercantilist competition between European powers created an early form of global economic integration by linking the Americas, Africa, Europe, and Asia into one trade system.
Mercantilism is the 16th-18th century European economic system where the state regulated trade to build national wealth, measured in gold and silver, by exporting more than it imported and using colonies as sources of raw materials and markets for finished goods.
No. Mercantilism relies on heavy government control of trade and assumes wealth is a fixed amount to compete over. Capitalism, especially Adam Smith's laissez-faire version from 1776, argues free markets with minimal state interference create new wealth. The AP World CED frames the shift from mercantilism to free trade as a key change in the 1750-1900 period.
They believed national power depended on hoarding bullion and outselling rivals, so monarchs sponsored exploration, built colonial empires, and restricted colonial trade to keep wealth flowing home. This is the economic cause behind Portuguese, Spanish, English, French, and Dutch voyages in Unit 4.
It was a major driver. Mercantilist colonies existed to produce exports like sugar and tobacco, and plantation owners turned to enslaved African labor to maximize that output. The CED connects these economic developments to social transformations under learning objective 4.8.A.
There is no single end date, but the AP answer is that Western European countries began abandoning mercantilism for free trade policies in the 1750-1900 period, largely because Adam Smith's Wealth of Nations (1776) made the case for laissez-faire capitalism.
