Rule of law is the principle that every person, even those in power, must follow and is accountable to the same laws that govern everyone else. In AP Gov, it's one of the four core American values (Topic 4.1) and the foundation behind checks and balances and impeachment (Topic 1.6).
Rule of law is the idea that the law sits above everyone, including the people who write and enforce it. The CED defines it exactly this way in Topic 4.1: every person, even those in power, must follow and is accountable to the same laws that govern all. No president, senator, or judge gets a personal exemption.
The flip side of rule of law is arbitrary governance, where outcomes depend on who you are or who you know rather than what the law says. The Constitution builds rule of law into the structure of government itself. Separation of powers and checks and balances exist so that if an official abuses power, there's a legal process to hold them accountable (think impeachment in the House and removal after a Senate trial). Federalist No. 51 makes the underlying logic famous: because men aren't angels, you need a government that can control the governed and also control itself.
Rule of law shows up in three places in the CED, which makes it unusually high-yield. In Topic 1.1 (Ideals of Democracy), it underpins limited government, the idea that government power cannot be absolute. In Topic 1.6 (Principles of American Government), learning objectives 1.6.A and 1.6.B explain how separation of powers and checks and balances put rule of law into practice, including legal actions like impeachment and removal against officials who abuse power. In Topic 4.1 (American Attitudes about Government and Politics), learning objective 4.1.A names rule of law as one of the four core values, alongside individualism, equality of opportunity, and free enterprise, that shape how citizens view the federal government. If you can connect a structural feature from Unit 1 to a core belief from Unit 4, you're doing exactly what the exam rewards.

Checks and Balances (Unit 1)
Checks and balances is rule of law turned into machinery. Each branch can legally restrain the others, so accountability doesn't depend on anyone's good intentions. Impeachment and removal are the clearest example of the law reaching the powerful.
Due Process (Units 1 and 3)
Due process is rule of law applied to individuals. It guarantees the government follows fair, consistent legal procedures before taking your life, liberty, or property, which is what 'same laws for everyone' looks like in a courtroom.
Judicial Review (Unit 2)
Judicial review lets courts strike down government actions that violate the Constitution. Since Marbury v. Madison, it's been the main enforcement tool ensuring even Congress and the president stay subject to the highest law.
Limited Government (Unit 1)
Limited government is the democratic ideal that power cannot be absolute, and rule of law is what makes that limit real. The Constitution writes the limits down; rule of law means officials actually have to obey them.
Rule of law is most likely to appear in multiple-choice questions asking you to identify which core American value a scenario illustrates or challenges. Classic stems include a government official getting preferential treatment in a criminal investigation (a direct violation of rule of law) or Yick Wo v. Hopkins (1886), where the Court struck down a law applied in a discriminatory way against Chinese laundry owners, reinforcing that laws must be applied equally. You may also see tension questions, like affirmative action pitting equality of opportunity against individualism, where you have to pick the right pair of values. No released FRQ has used the term verbatim, but it's a natural fit for the Concept Application FRQ and for Argument Essays that cite Federalist No. 51, since the whole document argues for structures that keep power accountable to law.
These overlap but aren't identical. Limited government (Topic 1.1) is the ideal that government power cannot be absolute. Rule of law (Topic 4.1) is the principle that everyone, including officials, is accountable to the same laws. Think of limited government as the goal and rule of law as one of the conditions that achieves it. On the exam, if a question is about the structure restraining government (separation of powers, federalism), it's pointing at limited government. If it's about equal application of laws or holding an official accountable, it's rule of law.
Rule of law means every person, even those in power, must follow and is accountable to the same laws that govern all (the CED's exact definition in Topic 4.1).
It is one of the four core American values, along with individualism, equality of opportunity, and free enterprise, that shape citizens' attitudes about government.
Checks and balances and separation of powers (Topic 1.6) enforce rule of law by allowing legal action, including impeachment and removal, against officials who abuse power.
Federalist No. 51 explains why these structures are necessary, since government must be designed to control itself, not just the governed.
Yick Wo v. Hopkins (1886) is a go-to example of rule of law, because the Court struck down a law that was applied in a discriminatory way against Chinese laundry owners.
A scenario where someone powerful gets special treatment under the law is a direct challenge to rule of law, and that's the most common way MCQs test it.
It's the principle that every person, even those in power, must follow and is accountable to the same laws that govern everyone. The CED lists it in Topic 4.1 as one of four core American values, and Topic 1.6 shows how checks and balances enforce it.
No, but they're related. Limited government is the ideal that government power can't be absolute, while rule of law specifically means laws apply equally to everyone, officials included. Rule of law is one of the mechanisms that makes limited government real.
Rule of law is the broad principle that everyone is subject to the same laws, while due process is its application to individuals, guaranteeing fair legal procedures before government takes your life, liberty, or property. Due process is rule of law in action at the personal level.
Yick Wo v. Hopkins (1886) is a strong one. The Supreme Court struck down a San Francisco law applied in a discriminatory way against Chinese laundry owners, reinforcing that laws must be applied equally to all. Impeachment and removal of officials also illustrate it.
Yes, that's the whole point. The Constitution gives the House the power to impeach and the Senate the power to remove a president who abuses power, which is the CED's main example of rule of law being enforced through checks and balances.
