# Fourteenth Amendment (Ratified July 9, 1868) > All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. The Fourteenth Amendment to the United States [[Constitution]] — ratified July 9, 1868 as part of the [[Reconstruction Amendments]] — is the most consequential constitutional provision after the original [[Bill of Rights]]. Its five sections restructured the relationship between federal and state power, established birthright citizenship, created the equal protection and due process guarantees that underpin virtually all modern civil rights law, and included a disqualification clause for insurrectionists that lay dormant for 150 years before being invoked against a former president. The Amendment matters for the KB because the conservative legal project to narrow its reach is the single most consequential legal battle in American politics. Nearly every major rights question of the last 75 years — desegregation, reproductive autonomy, marriage equality, affirmative action, voting rights, and now insurrection disqualification — runs through the Fourteenth Amendment. The [[Federalist Society]]-trained judicial supermajority is systematically contracting its protections, and understanding this project requires understanding the Amendment's architecture. Note: The Fourteenth is also covered in [[Reconstruction Amendments]] as part of the 13th-14th-15th package and its historical undermining. This page goes deep on the Fourteenth's individual doctrinal elements and their contemporary deployment. ## Section 1: The Four Clauses ### Citizenship Clause > All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. Birthright citizenship — *jus soli* — established as constitutional text. Overruled *[[Dred Scott v. Sandford]]* (1857), which held that Black people could never be citizens. The clause's "subject to the jurisdiction thereof" language was historically understood to exclude only children of foreign diplomats and enemy occupiers. **Contemporary assault.** The Trump administration issued an executive order in early 2025 purporting to end birthright citizenship for children of undocumented immigrants, arguing that such parents are not "subject to the jurisdiction" of the United States. This interpretation contradicts 150+ years of settled law, [[United States v. Wong Kim Ark]] (1898), and the plain historical meaning of the clause. Federal courts immediately blocked enforcement. The [[Heritage Foundation]] and allied organizations have provided the intellectual infrastructure for this challenge, reframing birthright citizenship as a "misinterpretation" despite its textual clarity. **The 2026 reaffirmation — and its limit.** In [[Trump v. Barbara]] (June 30, 2026), the Supreme Court struck down [[Executive Order 14160]] **6–3**, with Chief Justice [[John Roberts]] tracing *jus soli* from English common law through *Wong Kim Ark* and holding that U.S.-born children of unlawfully or temporarily present parents are "subject to the jurisdiction" of the United States. But the Court reaffirmed the Citizenship Clause on the **constitutional question by only 5–4**: Justice [[Brett Kavanaugh]] concurred in the judgment on statutory grounds alone (the order violated 8 U.S.C. §1401(a)) and wrote that Congress could amend the statute to create exceptions to birthright citizenship without offending the Fourteenth Amendment. Together with the three dissenters, that leaves four justices who would permit ending birthright citizenship by ordinary legislation — so the constitutional guarantee, though intact, now rests on a single vote. If the current Supreme Court narrows the Citizenship Clause, it would be the largest formal contraction of Fourteenth Amendment rights since *Plessy v. Ferguson* (1896). ### Privileges or Immunities Clause > No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States. This clause was intended by its framers to be the primary vehicle for protecting fundamental rights against state infringement. The *Slaughter-House Cases* (1873) — decided just five years after ratification — gutted it by distinguishing between national and state citizenship and holding that the clause protected only a narrow category of rights derived from national citizenship (like access to federal courts and navigable waters). This judicial evisceration is widely regarded as one of the worst decisions in Supreme Court history, and its consequences shaped all subsequent constitutional development: because Privileges or Immunities was killed, the heavy lifting of rights-protection against states shifted to the Due Process and Equal Protection Clauses, producing doctrinal frameworks the framers never intended. ### Due Process Clause > nor shall any State deprive any person of life, liberty, or property, without due process of law The Due Process Clause operates in two distinct doctrinal modes: **Procedural due process:** The government must follow fair procedures before depriving someone of life, liberty, or property — notice, hearing, opportunity to be heard. Relatively uncontroversial. **Substantive due process:** Certain rights are so fundamental that no process is sufficient to justify government infringement. This doctrine — which reads "liberty" as encompassing unenumerated fundamental rights — produced the constitutional protections for contraception (*Griswold*), interracial marriage (*Loving*), abortion (*Roe*, overturned by *Dobbs*), intimate conduct (*Lawrence*), and same-sex marriage (*Obergefell*). *[[Dobbs v. Jackson Women's Health Organization]]* (2022) explicitly contracted substantive due process by holding that unenumerated rights must be "deeply rooted in this Nation's history and tradition" — a test that would exclude any right not recognized in 1868 (or, per Alito's methodology, in centuries of prior common-law tradition). [[Clarence Thomas]]'s concurrence called for overruling *Griswold*, *Lawrence*, and *Obergefell* using the same reasoning. ### Equal Protection Clause > nor deny to any person within its jurisdiction the equal protection of the laws The clause that ended legal segregation (*[[Brown v. Board of Education]]*, 1954), struck down anti-miscegenation laws (*[[Loving v. Virginia]]*, 1967), and established heightened scrutiny for race- and sex-based classifications. The doctrinal framework: **Strict scrutiny** for race-based classifications (must be narrowly tailored to a compelling government interest). **Intermediate scrutiny** for sex-based classifications (must be substantially related to an important government interest). **Rational basis** for everything else (must be rationally related to a legitimate government interest). **Affirmative action reversal.** *Students for Fair Admissions v. Harvard* (2023) effectively ended race-conscious admissions in higher education, holding that Harvard and UNC's programs violated the Equal Protection Clause. Chief Justice [[John Roberts]]'s majority opinion inverted the clause's historical purpose — written to protect newly freed Black citizens from discriminatory state action — into a prohibition on programs designed to remedy the ongoing effects of that discrimination. The opinion represents the completion of a decades-long project to transform "equal protection" from a sword against racial hierarchy into a shield protecting the racial status quo. ## Section 2: Apportionment > Representatives shall be apportioned among the several States according to their respective numbers, counting the whole number of persons in each State... But when the right to vote at any election... is denied to any of the male inhabitants of such State, being twenty-one years of age, and citizens of the United States, or in any way abridged... the basis of representation therein shall be reduced in the proportion which the number of such male citizens shall bear to the whole number of male citizens twenty-one years of age in such State. The penalty clause: if a state denies the vote to eligible citizens, its congressional representation is proportionally reduced. It has never been enforced. Not once. During the decades when Southern states disenfranchised virtually their entire Black population through poll taxes, literacy tests, and violence, no state lost a single House seat. Section 2 is the textbook example of a constitutional enforcement mechanism rendered meaningless by political unwillingness to invoke it. ## Section 3: Insurrection Disqualification > No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath... to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. Originally applied to former Confederate officials after the [[American Civil War]]. Congress removed the disability for most ex-Confederates in 1872 and for all remaining ones in 1898. The clause lay dormant for over 150 years. **The Trump cases (2023-2024).** Following the [[January 6 Capitol Attack]], voters and officials in Colorado and Maine moved to disqualify Trump from presidential primary ballots under Section 3, arguing he had "engaged in insurrection." The Colorado Supreme Court ruled Trump disqualified; Maine's Secretary of State reached the same conclusion. *Trump v. Anderson* (2024): The U.S. Supreme Court reversed unanimously on jurisdictional grounds, holding that states cannot unilaterally enforce Section 3 against federal candidates — only Congress can do so through implementing legislation. The Court did not reach the merits of whether Trump "engaged in insurrection." The decision effectively rendered Section 3 unenforceable absent congressional action (which Congress has not taken and is unlikely to take given partisan composition). The ruling's structural implication: a constitutional disqualification provision that cannot be enforced without the consent of the political faction that committed the insurrection is a dead letter. This parallels the broader KB pattern of rights without enforcement infrastructure. ## Section 4: Public Debt > The validity of the public debt of the United States, authorized by law... shall not be questioned. Originally designed to prevent future Congresses from repudiating Union Civil War debt or assuming Confederate debt. Has been invoked in modern debt-ceiling crises as a potential basis for presidential authority to continue paying obligations despite a statutory debt limit — the argument being that the debt ceiling itself violates Section 4 by threatening the validity of authorized debt. No president has tested this theory. ## Section 5: Enforcement Power > The Congress shall have the power to enforce, by appropriate legislation, the provisions of this article. The enforcement clause — and its judicial narrowing — represents another front in the conservative legal project. *City of Boerne v. Flores* (1997) and *Shelby County v. Holder* (2013) limited Congress's Section 5 power by holding that enforcement legislation must be "congruent and proportional" to documented constitutional violations. [[Shelby County v. Holder]] used this framework to gut the [[Voting Rights Act of 1965]]'s preclearance regime, ruling that the coverage formula was based on outdated data — despite Congress's extensive evidentiary findings when reauthorizing the Act in 2006. ## The Incorporation Doctrine The Fourteenth Amendment's most practically consequential legacy may be the incorporation doctrine — the process by which the Supreme Court has applied most of the [[Bill of Rights]] against state and local governments through the Due Process Clause. The original Bill of Rights constrained only the federal government (*Barron v. Baltimore*, 1833). The Fourteenth Amendment's framers intended to change this, but the *Slaughter-House Cases* killed the most natural textual vehicle (Privileges or Immunities). The Court subsequently accomplished incorporation through Due Process instead — selectively "incorporating" individual Bill of Rights protections against the states over the course of the twentieth century. Today, nearly all Bill of Rights protections apply to states: the [[First Amendment]]'s speech and religion clauses, the [[Second Amendment]]'s right to bear arms (*[[McDonald v. Chicago]]*, 2010), the [[Fourth Amendment]]'s search-and-seizure protections, the [[Fifth Amendment]]'s self-incrimination and double-jeopardy protections, the [[Sixth Amendment]]'s trial rights, and the [[Eighth Amendment]]'s cruel-and-unusual-punishment bar. Without the Fourteenth Amendment's incorporation function, no state or city would be constitutionally bound by any of these protections. ## Why It Matters for the KB **The master battlefield.** The conservative legal project's most consequential ongoing work is narrowing the Fourteenth Amendment. Birthright citizenship (Citizenship Clause), reproductive autonomy and marriage equality (Due Process/substantive due process), affirmative action and anti-discrimination law (Equal Protection), voting rights enforcement (Section 5), and insurrection accountability (Section 3) — every major front in the culture war runs through this single amendment. The [[Federalist Society]] pipeline from law school to federal bench exists largely to populate courts with judges who will contract these protections. **The incorporation stakes.** If the Due Process Clause's incorporation doctrine were ever revisited, the entire structure of rights enforcement against state governments would collapse. Every [[Bill of Rights]] protection incorporated through the Fourteenth would become enforceable only against the federal government. This is not a live doctrinal threat but represents the theoretical endpoint of the strict-constructionist project. **Historical rhyme.** The Amendment was gutted once before — by the *Slaughter-House Cases*, *Cruikshank*, *Plessy*, and the post-Reconstruction courts that read it into meaninglessness. The current contraction project (Dobbs, Students for Fair Admissions, Shelby County, Trump v. Anderson) represents a potential second cycle of judicial narrowing. The KB tracks whether history is repeating. **Section 3 as accountability test.** The insurrection disqualification clause's fate — rendered unenforceable by a Court that declined to reach the merits — demonstrates the pattern: constitutional accountability mechanisms fail when the institutions responsible for enforcement are captured or unwilling. Connects to [[January 6 Capitol Attack]], [[Reconstruction and Its Overthrow]], and the broader theme of structural democratic vulnerability. ## See Also - [[Constitution]] — the foundational document - [[Bill of Rights]] — the first ten amendments, incorporated against states through this amendment - [[Reconstruction Amendments]] — the 13th-14th-15th package and its historical undermining - [[Reconstruction and Its Overthrow]] — how the Amendment was first gutted - [[Civil Rights Act of 1964]] — the [[Second Reconstruction]]'s legislative centerpiece - [[Voting Rights Act of 1965]] — Fifteenth Amendment enforcement gutted via Section 5 narrowing - [[Shelby County v.
