Brandenburg v. Ohio is the 1969 U.S. Supreme Court decision that set the modern First Amendment standard for when the government can punish speech that advocates illegal activity. The Court unanimously struck down Ohio’s criminal syndicalism law and held that even radical, inflammatory advocacy is constitutionally protected unless it is directed to inciting imminent lawless action and is likely to produce that action. That two-part requirement, now called the Brandenburg test, replaced looser standards the Court had used for half a century and still governs incitement cases today.
The Rally That Started It
Clarence Brandenburg, a Ku Klux Klan leader in Ohio, invited a Cincinnati television reporter to film a Klan rally in Hamilton County in the summer of 1964. The footage showed robed and hooded figures around a burning cross, some carrying firearms. Speakers directed hateful remarks at Black Americans and Jewish people and denounced the President, Congress, and the Supreme Court.1Justia. Brandenburg v. Ohio
On camera, Brandenburg said: “We’re not a revengent organization, but if our President, our Congress, our Supreme Court, continues to suppress the white, Caucasian race, it’s possible that there might have to be some revengeance taken.” He also mentioned a march on Washington planned for the Fourth of July.2Library of Congress. 395 US 444 – Brandenburg v. Ohio After the footage aired, Ohio prosecuted him.
The Law Ohio Used
Ohio charged Brandenburg under its Criminal Syndicalism Act, which made it a crime to advocate violence, sabotage, or other unlawful methods of achieving political or industrial change, and to voluntarily assemble with any group that taught those ideas. The statute did not require the state to prove that anyone acted on the speech, or even that anyone was likely to. Advocacy alone was enough.
Brandenburg was convicted, fined $1,000, and sentenced to one to ten years in prison.2Library of Congress. 395 US 444 – Brandenburg v. Ohio The Ohio intermediate appellate court affirmed, and the state supreme court dismissed his appeal without opinion. He then went to the U.S. Supreme Court.
What the Supreme Court Held
The Court reversed Brandenburg’s conviction in a per curiam opinion, issued by the Court as a whole rather than authored by a single justice. Its central holding was direct: a state cannot forbid advocacy of force or lawbreaking “except where such advocacy is directed to inciting or producing imminent lawless action and is likely to incite or produce such action.”1Justia. Brandenburg v. Ohio
The problem with Ohio’s statute, the Court said, was that it punished “mere advocacy” of violence with no requirement of any connection to imminent illegal conduct. A person could be convicted just for expressing the belief that revolution or sabotage was justified, even in the abstract, even to a small audience, and even if no one acted. That violated the First Amendment. The opinion also declared that “Whitney v. California cannot be supported” and directly overruled that 1927 precedent.2Library of Congress. 395 US 444 – Brandenburg v. Ohio
The Three-Part Brandenburg Test
Courts and scholars break the rule into three requirements that must all be satisfied before speech can be punished as incitement:
- Intent. The speaker must have specifically intended to provoke illegal conduct, not simply expressed a belief that illegal conduct is justified.
- Imminence. The illegal action must be imminent. Calls for revolution “someday” or violence at an unspecified future time do not qualify.
- Likelihood. The speech must be objectively likely to produce the illegal action. A speaker who wants to cause a riot is still protected if the audience is unlikely to follow through.
All three conditions must be met at the same time.1Justia. Brandenburg v. Ohio The bar is high by design. Abstract teaching, philosophical defense of radical ideas, and heated rhetoric about the desirability of illegal action all remain protected.
What the Test Replaced
For fifty years before Brandenburg, the Court had used standards that gave the government much more room to punish speech.
In Schenck v. United States (1919), Justice Oliver Wendell Holmes wrote that speech could be restricted if it created a “clear and present danger” of a harm Congress had the power to prevent. The formulation sounded protective, but courts applied it loosely enough to uphold convictions for distributing anti-war leaflets and running communist study groups.
By the Cold War, the standard had shifted further. In Dennis v. United States (1951), the Court upheld convictions of Communist Party leaders under a balancing test asking “whether the gravity of the evil, discounted by its improbability, justifies such invasion of free speech as is necessary to avoid the danger.”3Justia. Dennis v. United States The more serious the feared outcome, the less likely it needed to be. And Whitney v. California (1927) had earlier upheld a criminal syndicalism conviction under a “bad tendency” test that asked only whether speech tended to produce harmful results. Whitney stood until Brandenburg explicitly overruled it.
How Courts Have Applied the Test
Later cases show where the line falls in practice. The pattern is consistent: incitement prosecutions of pure speech almost always fail.
Hess v. Indiana (1973)
At an antiwar demonstration at Indiana University, police arrested Gregory Hess after he shouted “We’ll take the fucking street later” as officers were clearing protesters. The Supreme Court reversed his conviction, calling the statement nothing more than “advocacy of illegal action at some indefinite future time.” The words were not directed at any particular person or group and were not shown to be likely to produce imminent disorder.4Justia. Hess v. Indiana This is where most incitement cases collapse: if the speaker is not calling for action right now, Brandenburg protects the speech.
NAACP v. Claiborne Hardware Co. (1982)
Civil rights leader Charles Evers gave speeches urging Black citizens in Mississippi to boycott white-owned businesses, warning at times that those who broke the boycott would face consequences. White merchants sued, arguing the speeches incited violence and economic harm. The Court held that Evers’ “emotionally charged rhetoric” did not cross the Brandenburg line, writing that an advocate “must be free to stimulate his audience with spontaneous and emotional appeals for unity and action in a common cause. When such appeals do not incite lawless action, they must be regarded as protected speech.”5Justia. NAACP v. Claiborne Hardware Co. Heated political rhetoric, even with implicit threats, is not incitement unless all three parts of the test are met.
What Brandenburg Does Not Cover
Brandenburg governs incitement. Other categories of unprotected speech operate under separate rules and should not be confused with the incitement standard.
A true threat is a statement communicating a serious intent to commit violence against a particular person or group. It does not need to produce imminent action or be likely to spark a riot; what matters is whether the speaker expressed a genuine intention to harm. In Watts v. United States (1969), decided the same year as Brandenburg, the Court distinguished true threats from “political hyperbole.” An antiwar protester who said “the first man I want to get in my sights is L.B.J.” was engaging in crude political speech, not making a real threat, given the conditional phrasing and the audience’s laughter.6Justia. Watts v. United States In Counterman v. Colorado (2023), the Court held that the government must prove at least recklessness on the speaker’s part for a true-threat prosecution, and the majority noted that incitement requires a higher mental-state showing because it sits so close to protected political advocacy.7Supreme Court of the United States. Counterman v. Colorado
Fighting words are face-to-face insults so provocative that they are likely to cause an immediate violent reaction from the person targeted. The Court recognized this narrow exception in Chaplinsky v. New Hampshire (1942). Unlike incitement, fighting words are defined by their effect on the individual listener rather than the potential to spark broader illegal action. The Supreme Court has not upheld a fighting-words conviction since Chaplinsky itself.
Criminal solicitation, where a person asks or directs another individual to commit a specific crime, falls outside Brandenburg’s protection entirely. Telling a crowd that banks deserve to be robbed is abstract advocacy; handing someone a gun and telling them to rob the bank on the corner is solicitation. In United States v. Hansen (2023), the Court confirmed that criminal solicitation in the legal sense is much narrower than ordinary “encouragement” and requires conduct that goes well beyond expressing support for illegal activity in the abstract.
Why the Standard Still Holds
No Supreme Court decision has weakened Brandenburg. If anything, the trend has gone the other direction. Counterman explicitly reaffirmed that incitement demands a higher mental-state showing than other categories of unprotected speech, precisely because of how close it sits to protected political advocacy.7Supreme Court of the United States. Counterman v. Colorado
The practical consequence is that the government almost never successfully prosecutes pure speech as incitement. A speaker who tells a crowd that the government deserves to be overthrown, that violence is morally justified, or that a particular group should be harmed is protected as long as the words are not directed at producing immediate illegal action by an audience likely to act on them. That protection extends to speech most people find repulsive. Brandenburg himself was a Klan leader making racist threats on camera, and the Court still found his conviction unconstitutional. The principle behind the ruling is that the government’s power to silence speakers based on the content of their ideas is more dangerous than the speech.
