The 14th Amendment, explained in plain terms, is the Reconstruction-era addition to the U.S. Constitution that defines American citizenship, forbids states from denying anyone due process or equal protection of the laws, and gives Congress the power to enforce those guarantees through legislation. Ratified on July 9, 1868, it has five sections, and together they touch nearly every major civil rights question in American law.1National Archives. 14th Amendment to the U.S. Constitution: Civil Rights (1868)
Before this amendment, states could theoretically limit speech, restrict religious practice, or deny basic rights without violating the federal Constitution, because the Bill of Rights restrained only the federal government. And the Supreme Court had ruled in Dred Scott v. Sandford that people of African descent could not be U.S. citizens at all, free or enslaved.2Justia. Dred Scott v. Sandford The 14th Amendment overturned Dred Scott directly and set the stage for a century and a half of doctrine that reshaped what states are allowed to do to the people inside their borders.
Who Is a Citizen
Section 1 opens by defining citizenship. Anyone born or naturalized in the United States, and subject to U.S. jurisdiction, is a citizen of both the nation and the state where they live.3Congress.gov. U.S. Constitution – Fourteenth Amendment Birth on American soil is enough. It does not depend on the immigration status of a child’s parents or on the preferences of local officials.
The phrase “subject to the jurisdiction thereof” carves out narrow exceptions. Children born to foreign diplomats stationed in the U.S., and children born to enemy forces during a hostile occupation of American territory, fall outside the clause.4Congress.gov. Constitution Annotated – Citizenship Clause For everyone else born here, citizenship is automatic.
One boundary worth flagging: the amendment itself covers only birth on domestic soil. Citizenship for children born abroad is governed by federal statute rather than the Constitution, which means Congress can adjust those rules.5Office of the Law Revision Counsel. 8 USC 1401 – Nationals and Citizens of United States at Birth
Due Process of Law
The Due Process Clause forbids any state from taking a person’s life, liberty, or property without following fair legal procedures. It protects every person within a state’s borders, not just citizens.6Congress.gov. Amdt14.S1.3 Due Process Generally Courts read the clause as doing two different jobs.
Procedural Due Process
Before the government acts against you, it has to play by the rules. At minimum, that means notice of what is happening and a real chance to be heard before a neutral decision-maker.7Congress.gov. Amdt14.S1.5.4.3 Notice of Charge and Due Process If a city wants to demolish your building, it cannot show up with a bulldozer. It has to tell you why, let you object, and let an impartial body evaluate the dispute. What the specific procedures look like varies with what is at stake.
Substantive Due Process
Substantive due process looks not at the procedures but at whether the law itself is legitimate. The Supreme Court has read the word “liberty” to protect certain fundamental rights that are not written into the Constitution but are considered deeply rooted in American history and tradition.8Congress.gov. Amdt14.S1.6.3.1 Overview of Noneconomic Substantive Due Process This doctrine produced some of the most consequential rulings of the modern era. In Griswold v. Connecticut, the Court struck down a state ban on contraceptives and located a right to privacy in the amendment.9Justia. Griswold v. Connecticut In Obergefell v. Hodges, the Court held that the right to marry is a fundamental liberty under the Due Process Clause, extending marriage rights to same-sex couples nationwide.10Justia. Obergefell v. Hodges Which unenumerated rights qualify as fundamental remains actively debated.
Equal Protection of the Laws
The Equal Protection Clause requires every state to give all people within its borders the same legal protections. It targets government classifications: whenever a law treats one group differently from another, the state has to justify it.3Congress.gov. U.S. Constitution – Fourteenth Amendment How hard that justification has to work depends on who is being classified. Courts use three tiers of review.
- Strict scrutiny applies to laws that classify people by race. The government must prove the classification serves a compelling interest and is narrowly tailored to achieve it. Very few laws survive this test.11Legal Information Institute. Race-Based Classifications Overview
- Intermediate scrutiny applies to gender classifications, which must serve an important government interest and be substantially related to achieving it.
- Rational basis review applies to most other classifications, which only need a rational connection to a legitimate government purpose. Courts give legislators wide latitude here.12Congress.gov. Equal Protection and Rational Basis Review Generally
This clause produced Brown v. Board of Education, which held that racially segregated public schools are inherently unequal and dismantled the legal architecture of “separate but equal.”13Justia. Brown v. Board of Education of Topeka It continues to reshape the law. In 2023, the Court ruled in Students for Fair Admissions v. Harvard that race-conscious admissions programs at Harvard and the University of North Carolina violated the clause. The majority held that the universities’ programs used overbroad racial categories that lacked a meaningful connection to their stated educational goals, and that admissions are zero-sum, so a benefit to one applicant necessarily comes at the expense of another.14Justia. Students for Fair Admissions, Inc. v. President and Fellows of Harvard College
How the Bill of Rights Applies to the States
This is probably the amendment’s most far-reaching practical effect, and many people don’t realize it exists. The 14th Amendment gave the Supreme Court a textual basis to apply federal Bill of Rights protections to state and local governments, a process known as incorporation.15Congress.gov. Amdt14.S1.4.1 Overview of Incorporation of the Bill of Rights The Court did not do it all at once. It took a case-by-case approach called selective incorporation, asking whether a particular right is essential to due process.
Over more than a century, that process brought nearly all of the first eight amendments to bear on the states. Your right to free speech, to practice your religion, to be free from unreasonable searches, to have an attorney in a criminal trial, and to keep firearms for lawful purposes like self-defense all bind state governments today because of the 14th Amendment’s Due Process Clause.16Justia. McDonald v. City of Chicago
A few provisions remain unincorporated. The Third Amendment’s restriction on quartering soldiers has never been formally applied to the states. The Fifth Amendment’s grand jury indictment requirement does not bind state prosecutors, and the Seventh Amendment right to a jury trial in civil cases stays limited to federal courts. Everything else in the first eight amendments now operates the same way at every level of government.
Apportionment and Voting Rights
Section 2 changed how political power is counted. Congressional seats are distributed based on each state’s total population, replacing the original Constitution’s Three-Fifths Compromise, which had counted enslaved people as only three-fifths of a person.17Congress.gov. Fourteenth Amendment Section 2 Section 2 also carries a penalty: if a state denies voting rights to adult male citizens, its congressional representation can be reduced proportionally. An exception in the text permits disenfranchisement for “participation in rebellion, or other crime.”
That exception has had lasting consequences. In Richardson v. Ramirez, the Supreme Court relied on this language to uphold state laws stripping convicted felons of the vote, reasoning that Section 2 specifically contemplated such disenfranchisement and therefore it could not violate the Equal Protection Clause.18Justia. Richardson v. Ramirez The gendered “male inhabitants” language was later superseded by the 15th and 19th Amendments.
Disqualification for Insurrection
Section 3 bars certain people from ever holding public office again. Anyone who previously swore an oath to support the Constitution while serving in a government role, and then engaged in insurrection or rebellion against the United States, cannot serve as a member of Congress, a presidential elector, or any civil or military officer at the federal or state level. The same disqualification applies to anyone who gave aid or comfort to enemies of the country.3Congress.gov. U.S. Constitution – Fourteenth Amendment
A criminal conviction is not required. During Reconstruction, most officials disqualified under Section 3 had not been convicted of anything. The disqualification is not permanent either. Congress can lift it by a two-thirds vote in both chambers.
The question of who enforces Section 3 sat dormant for over a century before returning to national attention. In Trump v. Anderson (2024), the Supreme Court ruled that individual states cannot enforce Section 3 against candidates for federal office. Only Congress has that power against federal officeholders and candidates, drawing its authority from Section 5.19Justia. Trump v. Anderson States can still disqualify candidates for state-level offices under Section 3. What form congressional enforcement has to take against federal candidates was left open.
Public Debt and Enforcement
Section 4 declares that the validity of U.S. public debt, lawfully authorized, “shall not be questioned,” and covers federal obligations including pensions and bounties related to suppressing insurrection.20Congress.gov. Fourteenth Amendment Section 4 The same section voids any debts incurred in support of rebellion and prohibits any government from compensating former slaveholders for the loss of enslaved people.21Legal Information Institute. Public Debt Clause The public debt language has surfaced periodically in modern debates over the federal debt ceiling, with scholars and officials disagreeing about whether it constrains Congress’s ability to default on Treasury obligations.
Section 5 gives Congress the power to enforce the entire amendment through legislation.22Congress.gov. U.S. Constitution – Amendment 14 Section 5 This is the constitutional foundation for 42 U.S.C. ยง 1983, which lets individuals sue state and local officials who violate their constitutional rights while acting in an official capacity.23Office of the Law Revision Counsel. 42 USC 1983 – Civil Action for Deprivation of Rights Section 1983 is one of the most frequently used tools in federal court. Without it, the amendment’s guarantees would lack much of their practical bite, because individuals would have no straightforward way to hold government actors accountable.
