The first three amendments to the Constitution are the opening entries in the Bill of Rights, all ratified together on December 15, 1791.1National Archives. The Bill of Rights: A Transcription The First Amendment protects freedom of religion, speech, press, assembly, and petition. The Second Amendment protects the right to keep and bear arms. The Third Amendment prohibits the government from housing soldiers in private homes without the owner’s consent. The ten amendments in the Bill of Rights were added to answer critics who feared the new federal government would run over individual liberties, and courts have been defining what these three protect ever since.
The First Amendment
The First Amendment packs five separate protections into a single sentence. Each has generated its own body of law.
Religion
Two clauses govern religion. The Establishment Clause bars the government from creating a national religion or favoring one faith over another. The Free Exercise Clause protects your right to practice your chosen religion without government interference.2Congress.gov. First Amendment The government stays out of religion, and religion stays free of government control.
A federal statute called the Religious Freedom Restoration Act layers on additional protection. The federal government cannot substantially burden a person’s religious exercise unless it shows both that the burden advances a compelling government interest and that it uses the least restrictive means available.3Office of the Law Revision Counsel. 42 USC 2000bb-1 Free Exercise of Religion Protected Congress passed the Act after a 1990 Supreme Court decision allowed neutral, generally applicable laws to burden religious practice without heightened review.
Speech
Freedom of speech protects personal expression and political discourse from government interference. You can voice unpopular opinions, criticize elected officials, and advocate for change without punishment. The protection covers symbolic speech too, such as wearing an armband, burning a flag, or displaying a sign. But the right has limits.
The clearest line on advocacy of violence comes from Brandenburg v. Ohio, decided in 1969. The government cannot punish even extreme advocacy unless the speech is directed at producing imminent lawless action and is likely to actually produce it.4Library of Congress. Brandenburg v. Ohio Both prongs must be met. Vague calls for revolution at some undefined future date stay protected; urging a crowd to attack someone right now does not.
Other categories fall outside protection entirely. Fighting words, meaning face-to-face insults so provocative they are likely to cause an immediate violent reaction, can be punished. True threats can also be punished, and the Supreme Court clarified in 2023 that the government must prove the speaker consciously disregarded a substantial risk their words would be understood as a threat.5Supreme Court of the United States. Counterman v. Colorado Obscenity is unprotected as well, judged by a three-part test that weighs prurient appeal, patently offensive depiction of sexual conduct, and whether the work as a whole lacks serious literary, artistic, political, or scientific value.
When the government violates your free speech rights, a federal civil rights statute lets anyone whose constitutional rights have been violated by someone acting under state or local authority sue for damages.6Office of the Law Revision Counsel. 42 USC Ch. 21 Civil Rights
Press
Freedom of the press lets news organizations report on government without censorship. The strongest piece of this protection is the heavy presumption against prior restraint, meaning any attempt by the government to stop a publication before it reaches the public. In New York Times Co. v. United States, the Pentagon Papers case, the Supreme Court held that the government failed to meet its heavy burden of justifying such a restraint even when classified national defense material was at issue.7Library of Congress. New York Times Co. v. United States In practice, the government almost never succeeds at stopping a story before it runs.
Defamation is not protected speech, but the Constitution makes libel suits hard for public officials to win. Under the actual malice standard from New York Times Co. v. Sullivan, a public official must prove the speaker either knew the statement was false or acted with reckless disregard for its truth.8Justia U.S. Supreme Court Center. New York Times Co. v. Sullivan, 376 U.S. 254 (1964) Private individuals face a lower bar. In Gertz v. Robert Welch, Inc., the Court held that states may allow private plaintiffs to recover actual damages by proving negligence, though punitive damages still require actual malice.9Justia U.S. Supreme Court Center. Gertz v. Robert Welch, Inc., 418 U.S. 323 (1974)
Assembly and Petition
The right to peaceably assemble protects protests, marches, and rallies in public spaces. Local governments can impose reasonable restrictions on the time, place, and manner of gatherings, but those restrictions must be content-neutral. A city can require a permit for a march that blocks traffic. It cannot deny that permit because officials disagree with the marchers’ message.2Congress.gov. First Amendment
The right to petition covers signing petitions, filing lawsuits against the government, contacting representatives, and lobbying for legislation. Officials cannot retaliate against you for using any of these channels. People exercise this right constantly without thinking of it as a constitutional act.
The Second Amendment
The Second Amendment reads: “A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.”10Congress.gov. Second Amendment For most of American history, courts argued about whether this protected an individual right or only a collective right tied to militia service. The Supreme Court answered in 2008.
An Individual Right
In District of Columbia v. Heller, the Court struck down a Washington, D.C., handgun ban and held that the Second Amendment protects an individual’s right to possess a firearm for traditionally lawful purposes such as self-defense in the home, without any connection to militia service.11Supreme Court of the United States. District of Columbia v. Heller Two years later in McDonald v. City of Chicago, the Court extended this individual right to state and local governments through the Fourteenth Amendment.12Justia U.S. Supreme Court Center. McDonald v. City of Chicago, 561 U.S. 742 (2010) No city or state can simply ban handguns outright.
Carrying Firearms in Public
The 2022 decision in New York State Rifle & Pistol Association v. Bruen extended the right beyond the home. New York had required applicants for concealed carry permits to demonstrate a special need for self-defense. The Court struck the requirement down and held that the Second and Fourteenth Amendments protect the right to carry a handgun outside the home for self-defense.13Justia U.S. Supreme Court Center. New York State Rifle and Pistol Association Inc. v. Bruen, 597 U.S. (2022)
Bruen also changed how courts evaluate gun laws. When the amendment’s text covers someone’s conduct, that conduct is presumptively protected, and the government can only regulate it by showing the restriction is consistent with the nation’s historical tradition of firearm regulation. The Court did confirm that restrictions in sensitive places like courthouses, polling places, and legislative buildings remain valid.
Limits on the Right
The right is not unlimited. Federal law prohibits certain people from possessing firearms, including convicted felons and those adjudicated as mentally ill. Background checks are required for purchases from licensed dealers. These restrictions have survived challenges because Heller itself said longstanding prohibitions on possession by felons and the mentally ill are presumptively lawful.14Constitution Annotated. Amdt2.4 Heller and Individual Right to Firearms
The National Firearms Act separately regulates categories of weapons including machine guns, short-barreled rifles, and suppressors.15Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act These items must be registered with the ATF, and purchasers must submit fingerprints and pass a background check. Prohibited persons who possess firearms face up to 15 years in prison.16Office of the Law Revision Counsel. 18 USC 924 Penalties The general federal fine ceiling for any felony conviction is $250,000.17Office of the Law Revision Counsel. 18 U.S. Code 3571 Sentence of Fine
The Third Amendment
The Third Amendment is the shortest and least litigated of the three. It prohibits the military from housing soldiers in any private home without the owner’s consent during peacetime. In wartime, quartering can occur only as prescribed by a law passed by Congress.18Congress.gov. U.S. Constitution Third Amendment The amendment answered the British Quartering Acts, which had forced colonists to feed and shelter British troops in their own homes.
Case law on the Third Amendment is thin, but one ruling is worth knowing. In Engblom v. Carey, the Second Circuit Court of Appeals held that National Guard members qualify as “soldiers” under the amendment, that the amendment applies to state governments through the Fourteenth Amendment, and that the protection extends to anyone with a possessory interest in their living quarters, not just property owners.19Justia. Engblom v. Carey, 572 F. Supp. 44 (S.D.N.Y. 1983)
How These Amendments Apply to the States
By their text, the first three amendments restrict only the federal government. That is no longer how they function. Starting in 1925, the Supreme Court began treating the protections as binding on state and local governments through the Fourteenth Amendment’s Due Process Clause. In Gitlow v. New York, the Court held that freedoms of speech and press are among the fundamental liberties protected against state action.20Justia U.S. Supreme Court Center. Gitlow v. New York, 268 U.S. 652 (1925) Over later decades the Court extended incorporation to every clause of the First Amendment, to the Second Amendment through McDonald, and, at least in the Second Circuit, to the Third Amendment through Engblom. Today your local police department and your state legislature are bound by these amendments the same way Congress is.
