In AP Euro, slavery refers to the transatlantic system of forced, unpaid African labor that Europeans expanded to staff New World plantations after indigenous populations collapsed, fueling mercantilist economies (Topics 1.9, 3.4) and later driving abolitionist reform movements (Topic 6.8).
Slavery is a labor system in which people are legally owned, bought, and sold, and forced to work without pay. In AP Euro, the term almost always points to the transatlantic slave-labor system. Per KC-1.3.IV.C, Europeans expanded the trade of enslaved Africans because plantation economies in the Americas needed massive labor forces right when demographic catastrophes (mostly disease) wiped out indigenous populations. The result was the Middle Passage, planter society, and millions of Africans forcibly shipped across the Atlantic.
The course tracks slavery across three moments. In Unit 1, it begins as part of exploration and the early Atlantic economy. In Unit 3, it scales up. KC-2.2.II.B states the transatlantic slave-labor system expanded in the 17th and 18th centuries as European demand for sugar, tobacco, and other New World products grew, making slavery the engine of mercantilist wealth. In Unit 6, the story flips. Religious and nongovernmental reform movements between 1815 and 1914 worked to end both serfdom and slavery, making abolition one of the signature social reforms of the industrial era.
Slavery is one of the few concepts that threads through three separate units, which makes it a continuity-and-change goldmine. It supports AP Euro 1.9.A (explain the causes for and development of the slave trade), AP Euro 3.4.A (continuities and changes in economic development, 1648-1815), and AP Euro 6.8.A (social reform movements, 1815-1914). The underlying logic ties together the course's economic themes. Mercantilism only works if colonies produce cheap raw goods, plantations only produce cheap goods with forced labor, and the consumer revolution in Europe (your coffee, sugar, and tobacco) runs on that labor. Then the Enlightenment and 19th-century reform impulses turn against the system, so slavery also becomes evidence for how ideas drive political change.

Transatlantic Slave Trade (Unit 1)
This is the specific mechanism behind slavery in the course. Topic 1.9 covers the why (plantation economies plus indigenous demographic collapse) and the how (the Middle Passage). If a question says 'slave trade,' it wants causes and development, not just a description of bondage.
Mercantilism and the Plantation System (Unit 3)
Think of slavery as the labor input that made mercantilism profitable. Colonies sent sugar and tobacco to Europe, Europe sent manufactured goods to Africa, and enslaved people were trafficked to the Americas. That triangular loop is why KC-2.2.II.B says the system expanded as demand for New World products rose.
Abolition and 19th-Century Reform (Unit 6)
By Topic 6.8, slavery shows up as the problem reformers attack. Religious and nongovernmental movements, like the British abolitionist movement, pushed to end slavery and serfdom. Same institution, opposite exam task. Now you explain why people dismantled it instead of why they built it.
Enlightenment Ideas and the Haitian Revolution (Units 4-5)
The 2023 DBQ asked whether the Haitian Revolution was caused primarily by Enlightenment ideas or by the conditions of enslavement. Slavery is the hinge of that whole prompt, so knowing the lived conditions of the plantation system gives you half your argument.
Multiple-choice questions usually test slavery as economics, not ethics. Stems ask why the slave trade expanded (plantation economies plus indigenous population collapse), what the triangular trade did for European economies, or what Portuguese sugar plantations in Brazil demonstrate about mercantilist development. One practice question even asks which philosophical development emerged partly to justify African slavery, so be ready to connect slavery to ideas about race and hierarchy. On the FRQ side, slavery anchors big causation and CCOT arguments. The 2023 DBQ asked you to weigh Enlightenment ideas against the conditions of enslavement as causes of the Haitian Revolution. The strongest move is showing change over time, from expansion in the 1600s-1700s to abolitionist attack in the 1800s, since that arc spans three units and screams continuity-and-change essay.
Both are coerced labor systems, but they are not the same thing on this exam. Serfs in Eastern Europe were legally bound to the land and owed labor to a lord, but they were not property that could be bought and sold like chattel slaves, and serfdom existed inside Europe rather than across the Atlantic. The CED for Topic 6.8 lists ending serfdom and ending slavery as two separate reform targets (Russia abolished serfdom in 1861). If a question is set in Russia or Eastern Europe, it almost certainly means serfdom; if it involves the Atlantic, plantations, or Africans, it means slavery.
Europeans expanded the trade of enslaved Africans because New World plantation economies needed labor after disease devastated indigenous populations (KC-1.3.IV.C).
The transatlantic slave-labor system grew during the 17th and 18th centuries because European demand for New World products like sugar and tobacco kept rising (KC-2.2.II.B).
Slavery was the labor backbone of mercantilism and helped fuel Europe's consumer revolution, since goods like sugar and coffee were produced by enslaved workers.
Between 1815 and 1914, religious and nongovernmental reform movements worked to abolish slavery, making abolition a major 19th-century social reform (Topic 6.8).
Slavery and serfdom are different systems; slavery means people held as property in the Atlantic world, while serfdom bound Eastern European peasants to the land.
Slavery spans Units 1, 3, and 6, so it is ideal evidence for continuity-and-change essays tracing the Atlantic economy from expansion to abolition.
In AP Euro, slavery means the transatlantic system of forced African labor that Europeans expanded to work New World plantations. It appears in Topic 1.9 (the slave trade), Topic 3.4 (mercantilism), and Topic 6.8 (abolition movements).
Two reasons, per KC-1.3.IV.C. Plantation economies in the Americas created enormous demand for labor, and demographic catastrophes (mainly epidemic disease) killed off the indigenous workers Europeans had first exploited.
Enslaved people were chattel property who could be bought and sold, mostly Africans trafficked across the Atlantic, while serfs were Eastern European peasants legally tied to a lord's land. The CED treats them as separate reform targets in Topic 6.8.
Not directly. The CED credits 19th-century religious and nongovernmental reform movements, like the British abolitionists, with working to end slavery between 1815 and 1914. Industrialization shaped the reform era, but abolition was driven by organized moral and political campaigns.
It anchors causation arguments. The 2023 DBQ asked whether the Haitian Revolution was caused primarily by Enlightenment ideas or by the conditions of enslavement, so you needed to use slavery as evidence and weigh it against intellectual causes.
