Seditious conspiracy is a federal crime, codified at 18 U.S.C. § 2384, that punishes two or more people who agree to use force against the United States government. A conviction carries up to 20 years in federal prison and a fine as high as $250,000. The charge sits in unusual territory: harder to prove than ordinary conspiracy, less extreme than treason, and brought only in rare cases involving organized plots against governmental authority.
What the Law Prohibits
The statute does not criminalize a single act. It criminalizes the plan — the meeting of minds between two or more people who intend to use force for one of several prohibited purposes.
Those purposes, as laid out in the statute, fall into four categories:
- Agreeing to forcibly overthrow or destroy the U.S. government.
- Conspiring to levy war against the United States.
- Planning to use force to oppose the government’s authority or to block the enforcement of any federal law.
- Agreeing to forcibly seize U.S. government property.
Every category requires force. Without it, there is no seditious conspiracy. That requirement is what separates the crime from political speech, protest, and organizing that the Constitution protects.
What Prosecutors Have to Prove
A federal prosecutor must establish three things beyond a reasonable doubt.
Two or More Participants
This is a conspiracy charge, so it requires at least two people. One person acting alone cannot commit seditious conspiracy, no matter how violent the plan.
An Agreement With Specific Intent
The core element is the agreement — a shared understanding among the participants to pursue a common illegal goal. Prosecutors do not need a signed document or a recorded handshake. The agreement can be inferred from communications, coordinated behavior, and surrounding circumstances. Encrypted messages, recorded phone calls, weapons purchases, and training activities have all served as evidence in past cases.
The intent behind the agreement matters as much as the agreement itself. Prosecutors must show that the defendants specifically intended to achieve one of the prohibited objectives in the statute. Vague hostility toward the government is not enough. The conspirators must have aimed their agreement at a concrete unlawful purpose, such as forcibly stopping the enforcement of a federal law.
No Overt Act Required
This is where seditious conspiracy diverges sharply from ordinary federal conspiracy. Under the general conspiracy statute, 18 U.S.C. § 371, prosecutors must prove that at least one conspirator took some concrete step toward carrying out the plan. 1Office of the Law Revision Counsel. 18 U.S. Code 371 – Conspiracy to Commit Offense or to Defraud United States Seditious conspiracy has no such requirement. The crime is complete once the agreement to use force for a prohibited purpose is formed. 2Office of the Law Revision Counsel. 18 USC 2384 – Seditious Conspiracy Prosecutors still introduce overt acts when they can — stockpiling weapons or conducting paramilitary training obviously strengthens the case — but the law does not require them.
Where Protected Speech Ends and the Crime Begins
The word “force” does the heaviest lifting in the statute. You can publicly call for the abolition of a federal agency, burn a flag on the Capitol steps, or publish a manifesto arguing the government is illegitimate. None of that is seditious conspiracy. The crime begins only when people agree to use physical force or violence to achieve their aims against the government.
The Supreme Court drew the modern line between protected advocacy and criminal incitement in Brandenburg v. Ohio (1969). Under that standard, the government cannot punish advocacy of illegal action unless the speech “is directed to inciting or producing imminent lawless action and is likely to incite or produce such action.” 3Justia US Supreme Court. Brandenburg v. Ohio, 395 U.S. 444 (1969) Angry rhetoric at a rally, abstract calls for revolution, and hyperbolic social media posts do not meet that threshold. What crosses the line is a group of people who move beyond talk and form a genuine agreement to use violence against the government or its operations.
In practice, prosecutors look for tangible preparations for force: acquiring weapons, surveilling government buildings, rehearsing assaults, or building armed formations to physically obstruct government proceedings. The plan must involve actual violence or physical power directed at governmental authority, not heated disagreement about policy.
How Seditious Conspiracy Compares to Treason and Insurrection
Seditious conspiracy sits in Chapter 115 of the federal criminal code alongside treason and insurrection. 4Office of the Law Revision Counsel. Chapter 115 – Treason, Sedition, and Subversive Activities All three target conduct against governmental authority, but the differences matter.
Treason is the only crime defined in the Constitution itself. Article III, Section 3 limits it to two acts: levying war against the United States, or adhering to its enemies by giving them aid and comfort. 5Constitution Annotated | Congress.gov. Article III Section 3 – Treason The Constitution imposes a uniquely high evidentiary bar: no one can be convicted of treason without the testimony of two witnesses to the same overt act, or a confession in open court. One person can commit treason; seditious conspiracy requires at least two. Treason also demands allegiance to the United States as an element, while seditious conspiracy applies to anyone within U.S. jurisdiction. Treason carries a potential death sentence; seditious conspiracy does not.
Insurrection, under 18 U.S.C. § 2383, punishes anyone who incites, assists, or engages in a rebellion against the authority of the United States. It targets actual participation in or direct support of a rebellion, while seditious conspiracy targets the agreement to use force, even if the planned violence never happens. Insurrection carries a maximum of 10 years, half the ceiling for seditious conspiracy. 4Office of the Law Revision Counsel. Chapter 115 – Treason, Sedition, and Subversive Activities But insurrection includes a consequence that seditious conspiracy does not: anyone convicted is permanently barred from holding any federal office by the terms of the statute itself.
Penalties
The statutory penalties for seditious conspiracy are up to 20 years in prison, a fine of up to $250,000, or both. 2Office of the Law Revision Counsel. 18 USC 2384 – Seditious Conspiracy 6Office of the Law Revision Counsel. 18 U.S. Code 3571 – Sentence of Fine Twenty years is the ceiling, not the default. The actual sentence depends on the federal sentencing guidelines and the specific facts, including the defendant’s role, whether violence actually occurred, and whether anyone was harmed.
The Terrorism Enhancement
Federal law defines a “federal crime of terrorism” as a listed offense that was calculated to influence or affect government conduct through intimidation or coercion. 7Legal Information Institute. Definition: Federal Crime of Terrorism From 18 USC 2332b(g)(5) If a seditious conspiracy conviction fits that definition, the sentencing guidelines call for a sharp upward adjustment that can push the sentence well above what the base offense level would otherwise produce. Prosecutors sought and obtained the enhancement in several of the January 6 seditious conspiracy cases.
Consequences Beyond Prison
The sentence and fine are only part of what follows a conviction.
Firearms
Federal law permanently prohibits anyone convicted of a crime punishable by more than one year of imprisonment from possessing firearms or ammunition. 8Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Because seditious conspiracy carries up to 20 years, a conviction triggers this ban automatically. Violating the ban is itself a separate federal felony.
Federal Pension
Federal employees convicted of seditious conspiracy lose their government pension. Under 5 U.S.C. § 8312, a conviction under 18 U.S.C. § 2384 disqualifies the individual, and their survivors, from receiving any annuity or retired pay based on their federal service. 9Office of the Law Revision Counsel. 5 U.S. Code 8312 – Conviction of Certain Offenses For a career government employee or military retiree, that forfeiture can exceed any fine the court imposes.
Public Office
Section 3 of the Fourteenth Amendment bars anyone who previously swore an oath to support the Constitution from holding office again if they “engaged in insurrection or rebellion” against the United States. 10Constitution Annotated | Congress.gov. Fourteenth Amendment Section 3 – Disqualification From Holding Office Whether a seditious conspiracy conviction automatically triggers this disqualification is unsettled. The amendment’s text references insurrection and rebellion rather than seditious conspiracy specifically, and the mechanism for enforcement remains contested. Congress can remove the disability by a two-thirds vote of each chamber.
Voting
Seditious conspiracy is a federal felony, and felony convictions affect voting rights. The rules vary entirely by state. In some, a conviction has no effect on voting rights at all. Most states restore rights after incarceration or completion of parole and probation. A smaller number require a pardon or impose an additional waiting period. Many states also condition restoration on payment of outstanding fines, fees, and restitution.
Why the Charge Is Rarely Brought
Seditious conspiracy prosecutions are uncommon for practical reasons, not legal ones. The charge demands proof that defendants formed a genuine agreement to use force against the government, not just that they committed acts of violence, which can be charged more simply as assault or weapons offenses. Proving the existence of an agreement and the specific intent behind it is harder than proving someone broke a window or carried a weapon into a restricted area. Prosecutors tend to reach for the charge only when the evidence clearly shows an organized plot aimed at governmental authority itself, rather than isolated criminal acts that happened to occur during a political event.
The charge also carries political weight that makes prosecutors cautious. Bringing a seditious conspiracy case signals that the government views the defendants’ conduct as an attack on the constitutional order, not merely a collection of ordinary crimes. Juries have sometimes been reluctant to convict on a charge that sounds so extreme, even when the evidence of a violent conspiracy is strong.
