What Is the Definition of Sedition in U.S. Law?

Sedition in U.S. law is a federal crime defined by 18 U.S.C. § 2384, and it punishes an agreement between two or more people to use force against the United States government, its authority, its laws, or its property. The crime is the agreement itself. No shot has to be fired, no building seized, no law actually blocked. If two or more people form a genuine, shared plan to use physical force for one of the purposes the statute lists, the offense is already complete, and each person faces up to 20 years in federal prison.¹

What the Statute Actually Covers

Section 2384 reaches five kinds of forcible objectives when two or more people conspire to pursue them:

Overthrowing the government of the United States by force.
Levying war against the United States.
Using force to oppose the authority of the federal government.
Using force to prevent, hinder, or delay the execution of any federal law.
Using force to seize, take, or possess any property of the United States.

The common thread is physical force used to bypass legal processes. A sit-in at a federal building during a protest is not the same thing as a coordinated plan to take the building by force. The statute does not care how conspirators meet, organize, or communicate. What it cares about is the forcible objective they agreed on.¹

What the Government Has to Prove

A seditious conspiracy case rests on three elements. Prosecutors have to show that an agreement existed between at least two people, that the agreement involved using force for one of the statutory purposes, and that the defendants specifically intended to carry it out.¹

The agreement does not have to be written down or formally declared. A shared understanding worked out through meetings, messages, or coordinated preparation can satisfy the element. What has to be present is a mutual commitment, not parallel grievances.

Intent is where most of these cases turn. The government has to show that defendants genuinely intended to use force, not just that they talked about it. Angry speeches, inflammatory posts, even weapons stockpiling do not automatically add up to seditious conspiracy. Prosecutors need evidence that the conduct reflected a real, shared operational plan rather than fantasy or bluster.

One feature sets this statute apart from the general federal conspiracy law at 18 U.S.C. § 371: seditious conspiracy has no overt act requirement. The agreement itself is the completed crime. In practice, prosecutors still introduce overt acts because juries find a bare agreement hard to convict on, but the statute does not require any.¹

Where the First Amendment Draws the Line

Sedition is narrower than most people think. Harsh criticism of the government, abstract calls for revolution, and organizing around deeply unpopular political goals all sit inside the First Amendment. The dividing line is a concrete agreement to use physical force.

The Supreme Court drew that line in Brandenburg v. Ohio (1969). Advocacy of illegal action cannot be punished unless the speech is directed at producing imminent lawless action and likely to actually produce it.² Saying “the government deserves to be overthrown” to a crowd is protected. Telling armed co-conspirators “we attack the federal courthouse on Tuesday” likely is not. Specificity, imminence, and likelihood do the work.

This is where sedition prosecutions tend to fall apart. Juries are reluctant to convict when the evidence is mostly talk, even extreme talk. The convictions that have stuck involved detailed operational planning and concrete steps toward execution; cases built on inflammatory rhetoric alone tend to lose.

Penalties and Collateral Consequences

A seditious conspiracy conviction is a federal felony carrying up to 20 years in prison per defendant.¹ Because the statute directs that defendants “shall be fined under this title,” the maximum fine is set by the general federal sentencing provision at $250,000 for an individual convicted of a felony.³

The consequences do not end at the prison gate. Any offense punishable by more than one year of imprisonment triggers a lifetime federal ban on possessing firearms or ammunition under 18 U.S.C. § 922(g)(1).⁴ A felony record also affects employment, professional licensing, and voting rights in many jurisdictions.

Section 3 of the Fourteenth Amendment adds a separate consequence for anyone who previously swore an oath to support the Constitution as a federal or state official and then engaged in insurrection or rebellion. That person is barred from holding federal or state office, covering members of Congress, presidential electors, and civil and military officers at both levels.⁵ Whether a seditious conspiracy conviction by itself triggers that disqualification remains an open legal question, because Section 3 refers to “insurrection or rebellion” rather than to seditious conspiracy specifically.

How Sedition Differs From Treason and Insurrection

Sedition, treason, and insurrection get used interchangeably in ordinary conversation. They are three separate crimes.

Treason

Treason is defined in the Constitution itself and codified at 18 U.S.C. § 2381. It requires that the defendant owe allegiance to the United States and either levy war against the country or adhere to its enemies by giving them aid and comfort. Penalties range from death to a minimum of five years in prison and a fine of at least $10,000, with a permanent bar on holding federal office.⁶

The allegiance element is the key difference. Treason can only be committed by someone who owes loyalty to the United States, and historically it has involved aiding a foreign enemy. Seditious conspiracy has no allegiance requirement and focuses on domestic plots. A non-citizen on U.S. soil could face seditious conspiracy charges but likely not treason.

Insurrection and Rebellion

Under 18 U.S.C. § 2383, insurrection covers anyone who participates in, incites, or gives aid to an armed uprising against U.S. authority. The maximum penalty is 10 years in prison and a fine, and conviction bars the person from holding federal office.⁷

The practical difference from seditious conspiracy is timing. Insurrection punishes actual participation in or direct support of a violent uprising. Seditious conspiracy punishes the agreement to carry one out, even if the violence never happens. Sedition is the earlier-stage offense, which is why prosecutors can reach plots still in the planning phase.

Why Sedition Charges Are Rare

The federal government has brought seditious conspiracy charges only a handful of times in the past century, and the record is mixed. Prosecutors won convictions against members of a Puerto Rican nationalist movement in the 1950s after a plot that included a 1954 shooting inside the U.S. Capitol, and again after the 1993 World Trade Center bombing against Omar Abdel Rahman and nine co-defendants over a broader plan to attack New York City landmarks. An Arkansas jury acquitted all defendants from the white supremacist group “The Order” in the 1980s after a two-month trial. A 2010 prosecution of the Hutaree militia in Michigan collapsed when a federal judge ruled that plotting violence against individual government officials, without a broader plan to resist federal power itself, did not satisfy the statute.

The most recent prosecutions came out of the January 6, 2021 breach of the U.S. Capitol. Federal juries convicted members of the Oath Keepers and Proud Boys of seditious conspiracy, with sentences reaching 18 years. In 2025, the incoming presidential administration pardoned or commuted the sentences of many January 6 defendants, and in early 2026 the Department of Justice moved to vacate the seditious conspiracy convictions entirely. The pattern reflects how much prosecutorial discretion and political context shape whether sedition charges are brought, tried, and allowed to stand.
