Ratified on July 28, 1868, the 14th Amendment reshaped American constitutional law through five sections that, explained section by section, define national citizenship, restrict what state governments can do to individuals, rewrite how House seats are apportioned, bar oath-breaking insurrectionists from office, protect the public debt, and give Congress the power to enforce all of it by legislation.1National Archives. 14th Amendment to the U.S. Constitution – Civil Rights (1868) Proposed by Congress in 1866 during Reconstruction, the amendment’s first section alone contains four separate clauses that have generated more litigation than nearly any other part of the Constitution.
Section 1: Citizenship, Due Process, and Equal Protection
Section 1 does four distinct things. It declares that every person born or naturalized in the United States, and subject to its jurisdiction, is a citizen of the country and of the state where they live.2Congress.gov. Amdt14.S1.1.2 Citizenship Clause Doctrine It then bars states from abridging the privileges or immunities of U.S. citizens, from depriving any person of life, liberty, or property without due process of law, and from denying anyone within their jurisdiction the equal protection of the laws.1National Archives. 14th Amendment to the U.S. Constitution – Civil Rights (1868)
The Citizenship Clause directly overturned the Supreme Court’s 1857 ruling in Dred Scott v. Sandford, which had held that people of African descent could never be U.S. citizens.3Justia Law. Dred Scott v Sandford, 60 U.S. 393 (1856) By writing citizenship into the Constitution, the amendment took the question away from state legislatures and made it a federal birthright.
Who Is “Subject to the Jurisdiction”
The phrase “subject to the jurisdiction thereof” excludes a narrow set of people from automatic birthright citizenship. In United States v. Wong Kim Ark (1898), the Supreme Court read it to cover two situations from longstanding legal tradition: children born to foreign diplomats with immunity, and children born to enemy forces during a hostile occupation of U.S. territory. Almost everyone else physically present in the country, including children of noncitizen immigrants, is within U.S. jurisdiction and qualifies for citizenship at birth. At the time of ratification, the exclusion also applied to members of Native American tribes, who were treated as having a separate political relationship with the federal government.
Due Process and Equal Protection in Context
The Fifth Amendment already imposed a due process requirement on the federal government; Section 1 extended that requirement to every state and local government. The Equal Protection Clause did something new, forbidding official discrimination by state actors. In 1868, both clauses were aimed at preventing Southern states from maintaining legal systems that treated formerly enslaved people as less than full members of society. Over time, they became the basis for a much larger body of civil rights law reaching well beyond Reconstruction.
How Section 1 Made the Bill of Rights Apply to States
When the Bill of Rights was adopted in 1791, the Supreme Court held in Barron v. Baltimore (1833) that its protections limited only the federal government. A state could restrict speech or conduct unreasonable searches without violating the Constitution. Section 1’s Due Process Clause changed that. Through a case-by-case process called selective incorporation, the Supreme Court has spent more than a century applying most Bill of Rights protections against state and local governments by asking whether a particular right is essential to the American system of ordered liberty.4Congress.gov. Modern Doctrine on Selective Incorporation of Bill of Rights
Nearly all major Bill of Rights protections now bind state governments, including free speech, press, religion, assembly, and petition under the First Amendment; the right to keep and bear arms, incorporated in McDonald v. City of Chicago (2010);5Justia Law. McDonald v City of Chicago, 561 U.S. 742 (2010) the Fourth Amendment’s search and seizure rules; the Fifth Amendment’s protections against double jeopardy and compelled self-incrimination; the Sixth Amendment’s speedy trial, jury, confrontation, and counsel rights; and the Eighth Amendment’s limits on excessive bail, excessive fines, and cruel and unusual punishment.
A few provisions remain unincorporated. The Fifth Amendment’s grand jury requirement does not apply to the states, and the Third, Seventh, Ninth, and Tenth Amendments have no meaningful incorporation.4Congress.gov. Modern Doctrine on Selective Incorporation of Bill of Rights Still, incorporation is why your state government must respect most of the individual rights Americans take for granted.
Section 2: Apportionment of Representatives
Section 2 replaced the original Constitution’s three-fifths compromise, which had counted enslaved people as three-fifths of a person for purposes of House representation.6Constitution Annotated. Article I Section 2 Clause 3 The new rule counted every person as a whole person, excluding only Native Americans not taxed.7Constitution Annotated. Amdt14.S2.1 Overview of Apportionment of Representation Formerly enslaved people would now be fully counted, which ironically threatened to give the defeated Southern states more political power than they had held before the war.
Section 2 added a penalty to counterbalance that risk. If a state denied the vote to any of its male citizens aged twenty-one or older for any reason other than participation in rebellion or conviction of a crime, that state’s congressional representation would shrink in proportion to the number of citizens excluded.7Constitution Annotated. Amdt14.S2.1 Overview of Apportionment of Representation The reduction was never actually enforced against any state, even during decades of widespread voter suppression across the South.
What Later Amendments Overrode
Section 2’s original language is narrower than it reads today. Three later amendments expanded voting rights past its limits: the 15th Amendment (1870) prohibited denying the vote on account of race, color, or previous condition of servitude;8Congress.gov. Fifteenth Amendment the 19th Amendment (1920) prohibited denying the vote on account of sex, eliminating Section 2’s male-only framing;9Congress.gov. Nineteenth Amendment and the 26th Amendment (1971) lowered the voting age to eighteen. The “crime” exception remains relevant. It is the constitutional basis most often cited for state laws that strip voting rights from people with felony convictions.
Section 3: Disqualification From Office
Section 3 bars anyone from holding federal or state office if they previously swore an oath to support the Constitution and then engaged in an insurrection or rebellion, or gave aid or comfort to those who did.10Congress.gov. Fourteenth Amendment In 1868, this was aimed squarely at former Confederate officials. The provision covers members of Congress, military officers, state legislators, and state executive or judicial officers who broke their loyalty oath.
The disqualification is not permanent. Congress can lift it for a specific individual by a two-thirds vote of both chambers.10Congress.gov. Fourteenth Amendment Congress used this power extensively after Reconstruction, passing amnesty acts that restored political eligibility to most former Confederates.
Section 3 After January 6
Section 3 was largely dormant for over a century until it drew intense attention after January 6, 2021. Several states tried to invoke it to disqualify candidates from federal office. The most prominent case reached the Supreme Court as Trump v. Anderson in 2024. The Court unanimously reversed the Colorado Supreme Court’s decision to remove a candidate from that state’s presidential primary ballot, holding that states have no power to enforce Section 3 against federal officeholders or candidates. That responsibility belongs to Congress.11Supreme Court of the United States. Trump v Anderson (2024)
The ruling left significant questions open, including how Congress would go about enforcing Section 3 and whether a criminal conviction for insurrection is required before the disqualification applies. Historically, no conviction was necessary; most former Confederates who were barred from office were never tried for a crime. The modern enforcement mechanism remains untested.
Section 4: Validity of Public Debt
Section 4 declares that the validity of the public debt of the United States, as authorized by law, shall not be questioned.12Constitution Annotated. Fourteenth Amendment Section 4 The original motivation was direct. The Union had borrowed heavily to fund the war, and the amendment guaranteed those debts would be honored in full, including pensions and bounties paid to soldiers who fought to suppress the rebellion.13Congress.gov. Amdt14.S4.1 Overview of Public Debt Clause
The flip side is equally blunt. Neither the federal government nor any state may pay any debt incurred in support of the Confederate cause, and no former slaveholder may claim compensation for the loss of enslaved people who were freed.12Constitution Annotated. Fourteenth Amendment Section 4 All such debts and claims were declared void.
The Debt Ceiling Question
Section 4 was written with Civil War debts in mind, but the Supreme Court recognized in Perry v. United States (1935) that its language reaches further, covering whatever concerns the integrity of public obligations, including government bonds issued long after the amendment was adopted. That broader reading fuels a recurring argument about the federal debt ceiling. Some scholars argue that a statute forcing the government to default on existing obligations effectively questions the validity of the public debt. Others contend the debt ceiling is a political question courts would decline to resolve. No court has ruled directly on the issue, and the debate resurfaces each time Congress approaches the borrowing limit.
Section 5: Congressional Enforcement Power
Section 5 gives Congress the authority to enforce the entire amendment through legislation.14Congress.gov. Fourteenth Amendment Section 5 It is the constitutional foundation for landmark federal civil rights statutes, including laws prohibiting racial discrimination in public accommodations, employment, and voting.
The enforcement power has limits. In City of Boerne v. Flores (1997), the Supreme Court held that legislation enacted under Section 5 must be “congruent and proportional” to the constitutional injury Congress is trying to prevent or remedy.15Justia Law. City of Boerne v Flores, 521 U.S. 507 (1997) Congress can pass laws that enforce the amendment’s guarantees, but it cannot use Section 5 to redefine those guarantees or expand constitutional rights beyond what the amendment protects. The Court struck down the Religious Freedom Restoration Act as applied to states on that ground, and the “congruence and proportionality” test remains the standard for evaluating Section 5 legislation.
