The social contract is the Enlightenment political theory, developed by Hobbes, Locke, and Rousseau, that government's authority comes from an agreement in which individuals give up some freedoms in exchange for protection of their rights, making consent of the governed (not divine right) the basis of legitimate rule.
The social contract is the idea that government is a deal. People agree to give up some of their natural freedom and obey a ruler or state, and in return the state protects their remaining rights. The radical part isn't the trade itself. It's where authority comes from. Under this theory, a government is legitimate because the governed consent to it, not because God appointed the king or because tradition says so. That's exactly how the CED frames it (KC-2.3.III.A): political theories like Locke's argued the state originated in the consent of the governed rather than in divine right or tradition.
The catch is that 'the social contract' isn't one single theory. Hobbes (writing during the chaos of the English Civil War) argued people hand over power to an absolute sovereign to escape a brutal state of nature, and they can't take it back. Locke argued people only surrender limited power to protect their natural rights to life, liberty, and property, so a government that violates the contract can be overthrown. Rousseau pushed further, arguing legitimate government must express the 'general will' of the people. The CED (KC-2.3.I.B) names Locke and Rousseau as the developers of political models based on natural rights and the social contract, and it also flags Rousseau's controversial arguments for excluding women from political life (KC-2.3.I.C). Same phrase, three very different governments.
The social contract lives at the heart of Topic 4.3 (The Enlightenment) and supports learning objectives AP Euro 4.3.A and AP Euro 4.3.B, which ask you to explain the causes and consequences of Enlightenment thought and its influence on intellectual life. But its reach is much wider. It's the intellectual weapon that challenges absolutism in Unit 3, shapes enlightened absolutism in Topic 4.6 (rulers like Frederick II claimed to serve the state, not just rule it), and detonates in Unit 5, where the French Revolution turns 'consent of the governed' from salon talk into the Declaration of the Rights of Man. For the exam's big-picture themes, this term is your go-to evidence for KC-2.1, the idea that different models of political sovereignty changed the relationship between states and individuals across 1648-1815. If a question asks how Europeans rethought where political power comes from, the social contract is almost always part of the answer.

John Locke and Natural Rights (Unit 4)
Locke is the version of the social contract the exam tests most. Because people form government to protect natural rights, a government that violates those rights breaks the contract and can be legitimately overthrown. That single move justifies revolution, and it shows up directly in MCQs about Two Treatises of Government.
Absolutism and Divine Right (Unit 3)
The social contract is the direct counter-theory to divine right. Louis XIV claimed authority flowed down from God; contract theorists said it flows up from the people. Hobbes complicates this nicely, since he used a social contract to justify absolute power, just without the religious justification.
Effects of the French Revolution (Unit 5)
The Revolution is the social contract put into practice. The Declaration of the Rights of Man and Citizen reads like Locke and Rousseau turned into law, and revolutionary ideals even inspired Toussaint L'Ouverture's revolt in Saint-Domingue (KC-2.1.IV.F). This is the change half of any continuity-and-change argument about sovereignty from 1648 to 1815.
Enlightened Absolutism (Unit 4)
Rulers like Frederick II of Prussia and Joseph II of Austria absorbed Enlightenment language without accepting consent of the governed. Frederick called himself 'first servant of the state,' which borrows contract-style logic while keeping all the power. Great evidence for arguing Enlightenment ideas were adopted selectively.
Multiple-choice questions usually pair the social contract with a stimulus, often an excerpt from Locke, Hobbes, or Rousseau, and ask you to identify the argument or its implications. Practice questions hit two angles repeatedly. First, Locke's claim that a government violating the contract can be overthrown (tied to Two Treatises of Government and its influence on revolutions). Second, the contrast between Locke and Rousseau, including Rousseau's exclusion of women from political life, which the CED calls out explicitly. No released FRQ has used the phrase verbatim, but the social contract is prime LEQ and DBQ material for prompts about challenges to absolutism, causes of the French Revolution, or continuity and change in political sovereignty from 1648 to 1815. The skill being tested isn't reciting the definition. It's using the right thinker's version as evidence and explaining what changed because of it.
These are opposing answers to the same question, where does political authority come from? Divine right says God grants the monarch power, so subjects owe obedience and rebellion is sin. The social contract says the people grant the government power through consent, so a government that breaks the deal loses legitimacy. On stimulus questions, watch the direction authority flows. Down from God means divine right (think Bossuet and Louis XIV); up from the people means social contract (think Locke). Also don't collapse the contract theorists into one. Hobbes used the contract to defend absolute rule, while Locke used it to justify overthrowing tyrants.
The social contract is the theory that government authority comes from the consent of the governed, who trade some freedom for protection of their rights, rather than from divine right or tradition (KC-2.3.III.A).
Hobbes, Locke, and Rousseau each wrote a different version. Hobbes justified absolute sovereignty, Locke justified limited government and the right to revolt, and Rousseau grounded government in the general will.
Locke's version matters most for the exam because it argues a government that violates natural rights breaks the contract and can be legitimately overthrown, an idea that fueled the American and French Revolutions.
Despite its language of equality, social contract theory had limits. Rousseau argued for excluding women from political life, a contradiction the CED highlights and writers like Wollstonecraft attacked.
Use the social contract as evidence for the theme of changing political sovereignty (KC-2.1), connecting Unit 3 absolutism, Unit 4 Enlightenment thought, and Unit 5 revolution into one continuity-and-change argument.
It's the Enlightenment theory that government is based on an agreement where individuals give up some freedoms in exchange for protection of their rights, making consent of the governed the source of legitimate authority. The CED credits Locke and Rousseau with developing political models based on natural rights and the social contract.
No. Hobbes used the social contract to justify absolute monarchy, arguing people permanently surrender power to a sovereign to escape the violent state of nature. Locke supported limited government with a right to revolt, and Rousseau's 'general will' pointed toward popular sovereignty. Same concept, three different governments.
Locke focused on protecting individual natural rights (life, liberty, property) and argued people can overthrow a government that violates them. Rousseau argued legitimate government must express the collective 'general will,' and he controversially argued women should be excluded from political life, a contrast the AP exam has tested directly.
They're opposites. Divine right says the monarch's authority comes from God, so subjects must obey. The social contract says authority comes from the people's consent, so a government that breaks the agreement loses legitimacy. This is the core ideological shift from Unit 3 absolutism to Unit 5 revolution.
Revolutionaries used contract logic to argue Louis XVI had forfeited his legitimacy, and documents like the Declaration of the Rights of Man and Citizen (1789) made consent and natural rights the basis of government. The CED notes these revolutionary ideals also inspired Toussaint L'Ouverture's revolt that created independent Haiti in 1804.
