Seditious conspiracy is a federal crime, defined by 18 U.S.C. § 2384, that punishes two or more people who agree to use force against the authority of the United States government. A conviction carries up to 20 years in federal prison.1Office of the Law Revision Counsel. 18 USC 2384 – Seditious Conspiracy Charges are historically rare, but the statute returned to prominence after the January 6, 2021 Capitol breach produced multiple convictions and sentences exceeding a decade.
What Prosecutors Have to Prove
Three elements sit at the heart of the offense. First, there must be two or more participants. A single person acting alone cannot be charged under this statute, no matter how extreme the conduct. Second, those participants must reach an agreement. The agreement does not need to be written or formal, but prosecutors have to show a shared understanding, usually built from coordinated communication, joint planning, and pooled resources. Third, the object of the agreement has to involve force or the threat of force against the federal government.1Office of the Law Revision Counsel. 18 USC 2384 – Seditious Conspiracy
The force element is where many prosecutions have failed. In 2010, charges against the Hutaree militia in Michigan were dismissed after a federal judge concluded that the government had not shown an agreement to use force against federal authority. Angry rhetoric, even rhetoric about armed resistance, was not enough on its own.
What Kinds of Plans the Statute Reaches
Section 2384 lists four categories of forcible action against the federal government:
- Conspiring to overthrow the government by forcibly removing officials or dismantling the federal structure.
- Conspiring to levy or wage war against the United States, including organizing paramilitary operations.
- Conspiring to oppose the authority of the government by force, or to prevent, hinder, or delay the execution of a federal law — for example, physically blocking the certification of an election or the enforcement of a court order.
- Conspiring to forcibly seize, take, or possess federal property, buildings, land, or documents.
Each category requires that force be the intended means. A group that organizes a letter-writing campaign to protest a federal policy is engaged in politics. A group that organizes to physically storm a federal building to stop that policy from being enforced has moved into the territory the statute covers.1Office of the Law Revision Counsel. 18 USC 2384 – Seditious Conspiracy The threat of force also qualifies when a group has the apparent means and intent to follow through, such as stockpiling weapons and drawing up tactical plans for an attack on a federal courthouse. The statute reaches the conspiracy itself; prosecutors do not need to prove the plan succeeded.
Where Protected Speech Ends
The First Amendment protects a wide range of political speech, including speech many people find alarming. You can publicly advocate for the overthrow of the government, criticize federal officials in harsh terms, or argue that armed revolution is morally justified. None of that, standing alone, is seditious conspiracy.
In Brandenburg v. Ohio (1969), the Supreme Court held that the government cannot punish advocacy of illegal action unless that advocacy is directed at producing imminent lawless action and is likely to actually produce it.2Library of Congress. Brandenburg v Ohio, 395 US 444 (1969) That test shields abstract calls for revolution, heated protest chants, and extremist organizing, so long as no one has taken the step of forming a concrete agreement to use force. Seditious conspiracy picks up at that step. Once individuals move from advocacy to a plan, the First Amendment protection falls away.
Penalties
A seditious conspiracy conviction carries a maximum of 20 years in federal prison.1Office of the Law Revision Counsel. 18 USC 2384 – Seditious Conspiracy The court may also impose a fine of up to $250,000, the standard federal ceiling for felony offenses.3Office of the Law Revision Counsel. 18 US Code 3571 – Sentence of Fine
Actual sentences turn on the Federal Sentencing Guidelines, which weigh the degree of planning, the amount of force used or threatened, the defendant’s role in the conspiracy, and prior criminal history. Judges may order restitution when the conspiracy caused damage to federal property or injury to government personnel. Supervised release typically follows the prison term, keeping the defendant under federal monitoring with strict conditions for several additional years.
A felony at this level also triggers a federal firearms ban. Anyone convicted of a crime punishable by more than one year in prison is prohibited from possessing firearms or ammunition.4Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
How Long the Government Has to Charge It
The general federal statute of limitations for non-capital offenses is five years, and seditious conspiracy falls within it.5Office of the Law Revision Counsel. 18 USC 3282 – Statute of Limitations Because conspiracy is treated as a continuing offense, the clock generally starts when the last act in furtherance of the conspiracy takes place, not when the agreement was first formed. That rule can meaningfully extend the window for prosecution.
How It Differs From Treason and Insurrection
Treason is the more severe charge. It applies to anyone who owes allegiance to the United States and either levies war against the country or gives aid and comfort to its enemies. Penalties range from a minimum of five years in prison and a $10,000 fine up to death, and a conviction permanently disqualifies the person from any federal office.6Office of the Law Revision Counsel. 18 US Code 2381 – Treason The dividing line is the enemies requirement. Treason involves a foreign enemy or the act of levying war; seditious conspiracy reaches domestic plots to use force against federal authority, with or without any foreign connection.
The insurrection and rebellion statute, 18 U.S.C. § 2383, punishes anyone who incites, assists, or participates in a rebellion against the United States, with up to 10 years in prison and permanent disqualification from federal office. Unlike seditious conspiracy, it reaches individual participants and does not require proof of a group agreement.7Office of the Law Revision Counsel. 18 USC 2383 – Rebellion or Insurrection
Recent Convictions
For most of its history the statute was used only a handful of times, with mixed results. The January 6, 2021 Capitol breach changed that. Oath Keepers founder Stewart Rhodes was convicted and sentenced to 18 years in prison. Proud Boys leader Enrique Tarrio received 22 years, the longest sentence handed down in any January 6 case.8U.S. Department of Justice. Proud Boys Leader Sentenced to 22 Years in Prison on Seditious Conspiracy and Other Charges Co-defendants received sentences ranging from 10 to 18 years. Those cases confirmed that federal prosecutors can secure convictions even when the conspiracy fails to achieve its ultimate objective.
