The Enlightenment was a 17th-18th century European intellectual movement emphasizing reason, natural rights, and skepticism of traditional authority; in APUSH, its ideas crossed the Atlantic through print culture and gave colonists the political vocabulary to justify resistance and revolution.
The Enlightenment was an intellectual movement of the 1600s and 1700s built on a simple but radical idea. Human reason, not tradition, religion, or royal authority, should be the test of whether a law or government is legitimate. Thinkers like John Locke argued that people have natural rights (life, liberty, property) and that government exists through a social contract. If a government breaks that contract, the people can replace it.
For APUSH, what matters is how these ideas traveled and what colonists did with them. The CED (KC-2.2.I.A) says Enlightenment ideas spread to British North America as part of a larger transatlantic exchange of people and ideas, carried by the growing print culture of newspapers, pamphlets, and books. By the 1760s and 1770s, colonists resisting British taxes weren't inventing arguments from scratch. They were applying Enlightenment political thought, mixed with their own experience of self-government, to claim that Parliament was violating their rights (KC-2.2.I.D). The Declaration of Independence is basically Locke translated into a breakup letter to King George III.
The Enlightenment lives in two units. In Unit 2 (Topic 2.7, Colonial Society and Culture), it supports APUSH 2.7.A, which asks you to explain how the movement of ideas across the Atlantic shaped American culture, and APUSH 2.7.B, where Enlightenment political thought fuels colonists' growing mistrust of imperial control. In Unit 3, it becomes a cause of revolution. APUSH 3.5.A lists the colonists' "ideological commitment" as a factor in the Patriot victory, and that ideology is Enlightenment ideology. Topic 3.13 (APUSH 3.13.A) then asks you to trace how those ideals of self-government and liberty kept shaping society through 1800. The Enlightenment is one of the best continuity threads in the whole first half of the course, running from colonial pamphlets to the Declaration to the Constitution. It maps squarely onto the American and National Identity (NAT) theme.

Natural Rights and the Social Contract (Unit 3)
These are the Enlightenment's two workhorse ideas in APUSH. Natural rights say government can't take away what you're born with, and the social contract says government rules only by consent. Jefferson packed both into the Declaration of Independence almost word for word from Locke.
First Great Awakening (Unit 2)
The CED pairs these two movements in KC-2.2.I.A because both spread across colonial lines and taught ordinary people to question established authority. The Awakening did it through emotional religion, the Enlightenment through cold reason. Together they primed colonists to challenge Britain.
Transatlantic Print Culture and Anglicization (Unit 2)
Enlightenment ideas didn't teleport to America. They arrived in books, newspapers, and pamphlets as part of the same Anglicization process that made colonists feel English. The irony is that absorbing English political thought eventually gave colonists the tools to reject English rule.
American Revolutionary War (Unit 3)
APUSH 3.5.A credits the Patriots' "ideological commitment and resilience" as a reason they beat a richer, stronger Britain. That commitment was Enlightenment-fueled. Soldiers and civilians believed they were defending natural rights, which kept the cause alive through brutal years like Valley Forge.
Expect the Enlightenment in stimulus-based MCQs, usually attached to an excerpt from Locke, the Declaration of Independence, or a Revolutionary-era pamphlet, asking what intellectual tradition the author draws on. The right answer often hinges on spotting natural rights or social contract language. For essays, the Enlightenment is a go-to piece of evidence for causation arguments about the Revolution. The 2023 LEQ asking how transatlantic trade changed colonial society from 1607 to 1776 rewarded essays that connected commerce to the flow of ideas, since the same ships carrying goods carried Enlightenment texts. No released FRQ requires the word "Enlightenment" verbatim, but it strengthens almost any Period 2-3 argument about why colonists resisted Britain or how revolutionary ideals reshaped society. Don't just name-drop it. Explain the mechanism, meaning show how a specific idea (consent of the governed, natural rights) led to a specific action (Declaration, republican state constitutions).
Both swept the colonies in the 1700s and both undermined deference to traditional authority, so the exam loves to put them side by side. The difference is the source of truth. The Enlightenment trusted human reason and science; the Great Awakening trusted emotional, personal religious experience. The Enlightenment shaped elite political thought (Jefferson, Franklin), while the Awakening reached ordinary people through revival preachers like Whitefield and Edwards. If a stimulus talks about rights, reason, or contracts, think Enlightenment. If it talks about sin, salvation, or revival, think Awakening.
The Enlightenment was a 17th-18th century intellectual movement that made reason and natural rights, not tradition or monarchy, the standard for judging government.
Enlightenment ideas reached the colonies through transatlantic print culture, part of the broader exchange of people and ideas covered in Topic 2.7 (KC-2.2.I.A).
Colonists combined Enlightenment political thought with their local experience of self-government to justify resistance to British imperial control (KC-2.2.I.D).
Locke's natural rights and social contract theory show up almost directly in the Declaration of Independence, making the Enlightenment a core cause of the Revolution.
The Patriots' Enlightenment-based ideological commitment is one of the factors APUSH 3.5.A credits for the American victory despite Britain's military advantages.
Don't confuse it with the First Great Awakening; the Enlightenment used reason while the Awakening used religious emotion, though both weakened traditional authority.
The Enlightenment was a 17th-18th century intellectual movement emphasizing reason, natural rights, and skepticism of traditional authority. In APUSH it appears in Topic 2.7 as ideas spreading across the Atlantic and in Unit 3 as the ideological backbone of the American Revolution.
Not by itself. The CED lists Enlightenment political thought as one of several sources of colonial resistance, alongside local experience with self-government, religious diversity, and anger at imperial corruption (KC-2.2.I.D). On an LEQ, treat it as one major cause among several, which is exactly the kind of nuance that earns complexity points.
The Enlightenment was a secular movement based on reason and science; the First Great Awakening was a religious revival based on emotional, personal salvation. Both happened in the 1700s and both eroded deference to traditional authority, which is why the CED groups them together in Topic 2.7.
John Locke. His ideas about natural rights (life, liberty, property) and the social contract appear almost directly in Jefferson's Declaration of Independence in 1776, including the right of people to overthrow a government that violates their rights.
Mainly Units 2 and 3. It appears in Topic 2.7 (Colonial Society and Culture) as part of transatlantic intellectual exchange, in Topic 3.5 as fuel for the Patriot cause, and in Topic 3.13 as a continuity thread of self-government ideals running through 1800.
