First Amendment: Full Text and What It Protects

The First Amendment to the United States Constitution is a single 45-word sentence that protects five freedoms against government interference: religion, speech, press, assembly, and petition. Its full text and what it protects have been shaped by more than two centuries of Supreme Court interpretation, and each of the five freedoms now carries its own legal standard.

The Full Text

“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.”¹

Those words were ratified on December 15, 1791 as part of the Bill of Rights, the first ten amendments that set limits on federal power.² The sentence packs six distinct protections into one clause. Courts have treated each separately, so the practical meaning of the amendment depends on which right is at stake.

Who the First Amendment Binds

The amendment restricts government action. It does not reach private conduct. A private employer who fires you over something you said, a social media platform that removes your post, or a venue that cancels your event has not violated your First Amendment rights. The Supreme Court put it directly in Manhattan Community Access Corp. v. Halleck: the Free Speech Clause “prohibits only governmental, not private, abridgment of speech.”³

The opening words also matter: “Congress shall make no law.” Originally, only the federal government was bound. After the Fourteenth Amendment was ratified in 1868, the Supreme Court read its Due Process Clause to extend most Bill of Rights protections to state and local governments as well, a process known as incorporation.⁴ City councils, state legislatures, public school boards, and police departments are all now bound. A narrow exception treats a private entity as a government actor when it performs a traditional public function, is compelled by the government, or acts jointly with a government body.⁵ Outside those situations, First Amendment claims against private parties fail.

Religion: Two Clauses Working Together

The amendment’s first fourteen words contain two religion clauses. The Establishment Clause bars the government from sponsoring, promoting, or favoring any religion. The Free Exercise Clause protects your right to believe and practice as you choose.⁶

Establishment Clause

For decades, courts applied a three-part test from Lemon v. Kurtzman (1971) that examined secular purpose, primary effect, and government entanglement with religion.⁷ That is no longer the controlling standard. In Kennedy v. Bremerton School District (2022), the Supreme Court held that Establishment Clause questions should be decided by “reference to historical practices and understandings” rather than the Lemon framework. The case involved a public high school football coach who was fired for kneeling in silent prayer at midfield after games. The Court ruled for the coach and directed lower courts to draw the line between permissible and impermissible government involvement with religion “in accordance with history and the understanding of the Founding Fathers.”⁸ Lower courts are still working out what that means in practice.

Free Exercise Clause

Free exercise protects both belief and religious practice. When a law is not neutral toward religion or does not apply to everyone equally, courts apply strict scrutiny, the highest level of judicial review. The government must show a compelling reason for the restriction and prove that no less burdensome alternative exists.⁹ In Sherbert v. Verner (1963), the Court held that South Carolina could not deny unemployment benefits to a Seventh-Day Adventist who was fired for refusing to work on her Sabbath, because forcing her to choose between her faith and her livelihood placed an unconstitutional burden on her practice.¹⁰

Speech: What Is and Isn’t Protected

The speech clause covers more than spoken words. It extends to written work, symbolic conduct, political donations, and silence. The core question in most speech cases is whether the government is targeting the content of what you say or merely regulating when, where, and how you say it.

Protected Expression

Public speech on political, social, and cultural topics receives the strongest protection. You cannot be punished for holding unpopular views. Symbolic acts count too. In Texas v. Johnson (1989), the Supreme Court held that burning an American flag as political protest is protected expression, however offensive many people find it.¹¹

Content-neutral rules on the time, place, and manner of speech are allowed, but they must serve a significant interest, be narrowly tailored, and leave open other ways to communicate the same message.¹² A city can require a parade permit. It cannot deny the permit because officials dislike the marchers’ message.

Commercial Speech

Advertising is protected, but less strongly than political speech. Courts apply the four-part test from Central Hudson Gas and Electric Corp. v. Public Service Commission (1980): the speech must concern lawful activity and not be misleading, the government’s interest must be substantial, the regulation must directly advance that interest, and it must not be broader than necessary.¹³ That is why the government can prohibit false advertising but cannot broadly ban truthful ads for legal products.

Categories the First Amendment Does Not Protect

A few narrow categories of speech fall outside First Amendment protection. Courts have been reluctant to expand the list.

Incitement. Speech directed at producing imminent lawless action, and likely to produce it, can be punished. Vague calls for future rebellion or general advocacy of illegal conduct remain protected. This standard comes from Brandenburg v. Ohio (1969).¹⁴
Fighting words. Words aimed at a specific person that by their nature tend to provoke an immediate violent reaction, as recognized in Chaplinsky v. New Hampshire (1942).¹⁵
Obscenity. Material qualifies only if it meets all three parts of the Miller v. California (1973) test: the average person applying community standards would find it appeals to a sexual interest, it depicts sexual conduct in a patently offensive way as defined by state law, and the work as a whole lacks serious literary, artistic, political, or scientific value. Material with serious value is protected however explicit it is.¹⁶
True threats. Statements communicating a serious intent to commit violence against a particular person or group. Political rhetoric and hyperbole do not qualify.
Defamation. False statements of fact that damage reputation can create civil liability. For public officials and public figures, New York Times Co. v. Sullivan (1964) requires proof of “actual malice,” meaning the speaker knew the statement was false or acted with reckless disregard for whether it was true.¹⁷

Press and Prior Restraint

The press clause protects the ability of news organizations and journalists to gather and publish information about government activity. Its strongest feature is the near-total bar on prior restraint, meaning the government generally cannot block publication before it happens. In New York Times Co. v. United States (1971), the Pentagon Papers case, the government sought to stop the New York Times and Washington Post from publishing classified documents about the Vietnam War. The Supreme Court held that the government had not met the “heavy burden” required to justify a prior restraint, and publication went forward.¹⁸ Courts apply this protection to both traditional print outlets and digital media.

Assembly and Petition

The final clause protects two related rights: peaceable assembly and petitioning the government for a redress of grievances.¹ Assembly covers protests, rallies, marches, and public meetings. As with speech, content-neutral time, place, and manner rules are allowed. A government can require permits for large gatherings or limit them to certain hours and locations, but it cannot use those rules as cover for suppressing a particular viewpoint.¹² Participants cannot be punished simply for associating with an unpopular cause.

The petition right lets you contact representatives, lobby for policy changes, circulate petitions, and sue over government rules. It also protects you from government retaliation for doing so. In practice, this is the clause that keeps whistleblowers, activists, and ordinary citizens able to demand accountability without fear of official reprisal.

Students in Public Schools

Public school students keep their First Amendment rights, though schools can regulate expression that disrupts learning. In Tinker v. Des Moines (1969), the Supreme Court held that students do not “shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.” Schools can restrict student expression only when it would “materially and substantially interfere with the requirements of appropriate discipline in the operation of the school.” A vague worry that speech might cause a problem is not enough.¹⁹

Off-campus speech, including online posts, is handled differently. In Mahanoy Area School District v. B.L. (2021), the Court sided with a student suspended from cheerleading over a profane weekend social media post made from a convenience store. The Court gave three reasons schools have less authority over off-campus expression: the school rarely stands in a parental role off campus, allowing regulation of all off-campus speech would effectively hand schools control over a student’s entire life, and public schools have their own interest in protecting students’ ability to voice unpopular views.²⁰ Schools may still act on serious off-campus bullying, direct threats against students or staff, or breaches of school computer systems.
