Quick answer: which part of the Fourteenth Amendment protects civil rights?
One‑sentence summary
The short answer is that Section 1 of the Fourteenth Amendment contains multiple clauses that together protect civil rights, and modern civil‑rights law most often relies on the Due Process Clause and the Equal Protection Clause for state action claims.
This explanation starts from the Amendment text and then walks through how courts have used each clause in practice, so readers can see where doctrine is settled and where questions remain; the Amendment text is the primary source for those provisions National Archives Fourteenth Amendment text.

Why the question matters for voters and readers
Voters and civic readers often encounter claims that a single clause ‘protects’ a right. In practice, courts decide which clause applies based on the type of claim and the governing precedents, which affects the remedies available and who can bring a case.
Understanding which clause a case relies on helps readers interpret court opinions and public debates about civil rights, lawmaking, and enforcement; authoritative analysis and opinions explain those doctrinal choices in context Constitution Annotated.
What Section 1 of the Fourteenth Amendment says and why each clause matters
Text and immediate meanings of each clause
Section 1 contains four operative parts relevant to civil rights: the Citizenship Clause, the Privileges or Immunities Clause, the Due Process Clause, and the Equal Protection Clause, and together they form the Amendment’s core civil‑rights framework.
The plain text of Section 1 is the starting point for analysis, and readers should consult the historical language when comparing clauses and claims National Archives Fourteenth Amendment text. For a compact site overview of what the Amendment means in practice, see 14th Amendment meaning.
How the clauses relate to state action and individual rights
The Citizenship Clause defines national citizenship, which matters for determining who may claim protection under national law; it establishes that persons born or naturalized in the United States are national citizens, a foundation for later rights claims.
The Privileges or Immunities Clause originally promised to protect certain rights of national citizenship from state interference, but the scope of those rights has been subject to long legal debate and change; modern summaries of the Amendment describe how courts have treated these provisions over time Constitution Annotated.
The Due Process Clause bars states from depriving any person of life, liberty, or property without due process of law and has been a primary vehicle for applying many federal rights to the states through incorporation.
The Equal Protection Clause requires states to afford equal protection of the laws to persons within their jurisdiction and has been central to litigation that challenges state laws and practices as discriminatory.
Privileges or Immunities Clause: history, the Slaughter‑House Cases, and modern interest
The Slaughter‑House Cases and their effect
In the Slaughter‑House Cases of 1873 the Supreme Court interpreted the Privileges or Immunities Clause narrowly, a decision that sharply limited the Clause’s use as a route for national civil‑rights claims for many decades Slaughter‑House Cases opinion.
The practical consequence of that narrow reading was to shift most incorporation and national‑rights arguments to other provisions, notably the Due Process Clause.
Section 1 contains multiple clauses relevant to civil rights; modern civil‑rights enforcement has relied primarily on the Due Process and Equal Protection Clauses, while the Privileges or Immunities Clause was limited by the Slaughter‑House Cases and has only recently seen renewed interest.
Why some scholars and judges have urged revival
In recent decades some scholars and a minority of judges have argued that the Privileges or Immunities Clause deserves renewed attention as a textual and historical route to protect national rights against the states, though that view remains contested. For recent scholarly discussion see a law review note and commentary such as IJ analysis.
Analyses of modern opinions and scholarship note this renewed interest but also emphasize that, as of 2026, the Clause has not replaced the established doctrinal pathways used by courts Constitution Annotated.
Due Process Clause and incorporation: how most Bill of Rights protections reached the states
Original development of incorporation doctrine
Beginning in the early 20th century, courts increasingly relied on the Fourteenth Amendment’s Due Process Clause to make many protections in the Bill of Rights enforceable against state governments; this process is known as incorporation and became the dominant judicial approach.
Authoritative legal summaries explain that incorporation proceeded case by case, with courts analyzing whether a particular right was fundamental to the concept of ordered liberty before applying it to the states Constitution Annotated.
Role of the Due Process Clause in modern incorporation cases
In modern incorporation cases the Due Process Clause has served as the primary doctrinal vehicle for applying federal rights at the state level, and some major opinions reaffirm that approach while acknowledging doctrinal complexity.
One high‑profile example that highlights ongoing doctrinal questions is the Court’s treatment of Second Amendment incorporation in McDonald v. City of Chicago, which illustrates both reliance on Due Process and the presence of alternative views McDonald v. City of Chicago opinion.
Equal Protection Clause: the central tool against state discrimination
Historic uses: Brown and ending school segregation
The Equal Protection Clause has been the primary constitutional instrument for challenging state laws and practices that are discriminatory in purpose or effect, most famously in the Court’s decision in Brown v. Board of Education that rejected state‑sponsored school segregation.
The Brown opinion remains a landmark example of Equal Protection in action and shows how the Clause can correct entrenched, state‑sanctioned discrimination Brown v. Board opinion.
How Equal Protection is applied today
Today Equal Protection challenges appear in many contexts, including claims about race, sex, and other classifications; courts assess such claims by asking whether a law makes an unjustified or unconstitutional distinction among persons.
Legal analyses note that Equal Protection doctrine uses different levels of scrutiny depending on the classification at issue and the nature of the right, so outcomes turn on both factual findings and doctrinal categorization Constitution Annotated.
McDonald and the continuing doctrinal debate: Due Process versus Privileges or Immunities
What the Court held in McDonald v. City of Chicago
In McDonald v. City of Chicago the Supreme Court held that the Second Amendment right to keep and bear arms applies to the states, and the majority relied on principles associated with the Due Process Clause to incorporate that right against the states.
The McDonald majority’s reliance on Due Process underscores the clause’s long role in the incorporation project and shows how the Court frames fundamental‑rights analysis in practice McDonald v. City of Chicago opinion.
Why the concurrence matters for future doctrine
Although the majority used Due Process reasoning, a concurring opinion in McDonald urged renewed attention to the Privileges or Immunities Clause as an alternative route for incorporation, an argument that sparked scholarly discussion and some judicial curiosity.
Commentators and analysts have tracked this split reasoning because it highlights an open doctrinal question: whether future courts will shift toward the Privileges or Immunities Clause or continue to rely on Due Process for incorporation SCOTUSblog analysis of McDonald. For additional perspectives, see Cato Institute analysis.
How to decide which clause applies: practical criteria and jurisprudential signals
Common tests courts use
Courts choose among Equal Protection, Due Process, and occasionally Privileges or Immunities theories by looking at the text, precedent, history, and the substance of the asserted right; discriminatory classification claims generally proceed under Equal Protection while rights‑based incorporation claims have used Due Process.
Readers should remember that the choice of theory is procedural as well as substantive, because it affects the standard of review and the types of relief a court may order Constitution Annotated.

Use primary sources where possible
When advocates bring Equal Protection or Due Process claims
In practice lawyers often plead multiple theories when the factual record permits, for example advancing an Equal Protection claim for discriminatory intent while also asserting a Due Process claim for an incorporated liberty interest, because courts may accept one route over another.
The Constitution Annotated and major opinions provide the jurisprudential signals that practitioners use to decide which theories are most likely to reach the merits in a given jurisdiction Constitution Annotated.
Common mistakes and pitfalls when reading about the Fourteenth Amendment and civil rights
Misreading the scope of the Privileges or Immunities Clause
A common error is to assume the Privileges or Immunities Clause currently provides broad protections without acknowledging the effect of the Slaughter‑House Cases, which limited the Clause’s practical role for many decades.
Readers should check the Slaughter‑House opinion and later commentary to understand why that Clause has been historically dormant as a tool for national civil‑rights claims Slaughter‑House Cases opinion.
Confusing incorporation with federal guarantees
Another frequent pitfall is conflating the existence of a federal right with its enforceability against states; incorporation is the process that determines whether a federal right binds state governments, and that has been mostly handled through the Due Process Clause.
To avoid overreading commentary, look to primary documents and authoritative summaries for how the Court has handled incorporation decisions Constitution Annotated.
Practical examples: Brown, McDonald, and how a modern claim might proceed
Brown v. Board – Equal Protection in practice
Brown v. Board of Education applied the Equal Protection Clause to state‑sponsored school segregation, holding that separate educational facilities are inherently unequal and mandating desegregation in public schools.
Readers studying Brown should consult the opinion to see how the Court framed Equal Protection analysis in the context of entrenched state practices Brown v. Board opinion.
McDonald – incorporation debate in a modern case
As noted earlier, McDonald shows incorporation achieved through Due Process in the majority, accompanied by a concurrence urging the Privileges or Immunities Clause, and illustrates how a single case can fuel doctrinal debate.
That decision is useful for readers who want to compare majority and concurring reasoning on incorporation and to see how judges frame competing legal histories McDonald v. City of Chicago opinion.
A simple hypothetical to show clause selection
Imagine a plaintiff challenges a state law that singles out a racial group for exclusion from a public benefit; that claim would usually be framed under the Equal Protection Clause because it involves a discriminatory classification by the state.
By contrast, if a litigant argues that a fundamental free‑speech right in the Bill of Rights has been infringed by a state rule, the claim is often pleaded as an incorporated right under the Due Process Clause, following precedent and doctrinal practice Constitution Annotated.
