Lynching: Definition, Federal Law, and Civil Lawsuits

Lynching is an extrajudicial killing carried out by a mob acting under a claimed justification of enforcing social order, race, or tradition. The definition and federal law around lynching came together slowly: researchers settled on a four-part standard in 1940, but Congress did not make lynching a federal crime until the Emmett Till Antilynching Act was signed on March 29, 2022. That law treats lynching as a hate crime conspiracy under 18 U.S.C. § 249 and carries a maximum sentence of 30 years in prison.

What Counts as a Lynching

In 1940, anti-lynching activists meeting at the Tuskegee Institute agreed on four elements that had to be present before an incident would be classified as a lynching. All four must be met:

A death occurred.
The killing was illegal, happening outside any legal process.
A group carried it out, generally understood to mean three or more people.
The mob claimed a justification tied to enforcing justice, racial hierarchy, or tradition.

That fourth element is what separates lynching from other group killings. A bar fight that turns fatal involves a group, but the participants aren’t claiming to enforce a social order. Lynching mobs believed, or at least publicly declared, that they were serving a purpose higher than the law they were breaking. The Tuskegee criteria became the standard used by researchers, journalists, and government bodies for decades, and they remain the benchmark for historical counts. The U.S. Senate, in a 2005 resolution, acknowledged that at least 4,742 people, predominantly Black Americans, were reported lynched between 1882 and 1968, with documented incidents in all but four states.¹

How Federal Law Defines and Punishes Lynching Today

The Emmett Till Antilynching Act does not create a standalone federal crime called “lynching.” Instead, it amended the existing federal hate crime statute at 18 U.S.C. § 249 by adding two conspiracy provisions.²

Under subsection (a)(5), anyone who conspires to commit a hate crime offense that results in death or serious bodily injury faces up to 30 years in federal prison, a fine, or both. Under paragraph (a)(6), the same 30-year maximum applies when the conspiracy involves kidnapping, aggravated sexual abuse, or an attempt to kill.

“Serious bodily injury” is a defined federal term. It covers injuries involving a substantial risk of death, unconsciousness, extreme physical pain, obvious and lasting disfigurement, or prolonged loss of function of a body part or organ.³

The practical difference between the Tuskegee definition and the federal statute matters. The historical standard focused on what made lynching culturally distinct: mob action cloaked in social authority. The federal statute focuses on what makes it prosecutable: a conspiracy to commit bias-motivated violence that causes death or severe harm. A prosecutor does not need to prove the defendants believed they were enforcing a social order. The prosecution needs to show they conspired to commit a hate crime and that someone died or was seriously injured as a result.

The underlying hate crime offenses themselves already carried severe penalties before the 2022 amendment. If a hate crime based on race, color, religion, or national origin results in death, the defendant faces imprisonment for any term of years up to life. The Emmett Till Act filled a gap by specifically targeting the conspiracy element, recognizing that lynching is by its nature a group act.²

The law passed the House 422–3 and cleared the Senate unanimously before President Biden signed it. It is named for Emmett Till, a 14-year-old Black boy kidnapped and murdered in Mississippi in 1955 by two white men who were acquitted by an all-white jury.⁴

When Federal Prosecutors Can Bring a Case

Federal prosecutors cannot simply file charges under the Emmett Till Act whenever mob violence occurs. Section 249 requires a written certification from the Attorney General or a designee before any federal prosecution can go forward. The certification must establish that at least one of four conditions is met:²

The state lacks the legal authority to prosecute.
The state has asked the federal government to take over.
A state prosecution resulted in a verdict or sentence that left the federal interest in eliminating bias-motivated violence clearly unaddressed.
Federal prosecution is necessary to secure substantial justice.

Murder is traditionally a state crime. The federal government steps in only when the bias motivation triggers a federal interest that the state has not adequately addressed. This gatekeeping was the design choice that finally made the law acceptable to Congress after more than a century of failed bills.

A federal prosecution does not block a state prosecution for the same conduct. The Supreme Court reaffirmed in 2019 that because federal and state governments are separate sovereigns, prosecution by both for the same act does not violate the prohibition against double jeopardy.⁵ A defendant could face state murder charges and a separate federal conspiracy prosecution under the Emmett Till Act for the same killing.

Civil Lawsuits Available to Victims and Families

The criminal statute is not the only avenue. Survivors and the families of lynching victims have had a civil remedy since 1871, when Congress passed the Ku Klux Klan Act in response to racial violence in the South. That law, now codified at 42 U.S.C. § 1985(3), allows anyone injured by a conspiracy to deprive them of equal protection under the law to sue the conspirators for damages.⁶

The civil standard is different from the criminal one. A plaintiff does not need to prove the conspiracy was motivated by a specific protected characteristic listed in the hate crime statute. The claim requires showing that two or more people conspired to deny someone equal protection, that at least one conspirator took an action to advance the conspiracy, and that the plaintiff was injured as a result. Damages can cover the full scope of harm caused.

A related provision, 42 U.S.C. § 1983, creates potential liability for government officials and, in some circumstances, municipalities. The 1871 Act was passed in part because local police in the South routinely failed to protect Black citizens from mob violence. Under current law, a local government can be held liable when an official policy or widespread practice led to a failure to protect someone from a known threat of violence. Simple negligence by a single officer is not enough, but a pattern of deliberate indifference can be.

Why It Took Over a Century to Pass a Federal Law

The first federal anti-lynching bill was introduced on January 20, 1900, by Representative George Henry White of North Carolina, then the only Black member of Congress. The bill died in the Judiciary Committee without a vote.⁷ More than 200 anti-lynching bills followed over the 20th century, and every one failed. The Dyer Anti-Lynching Bill passed the House in 1922 but was filibustered to death in the Senate. The Costigan-Wagner Bill met the same fate in the 1930s.

Between 1890 and 1952, seven presidents petitioned Congress to act. The Senate found in its 2005 resolution that 99 percent of lynching perpetrators escaped punishment by state or local officials, and it formally apologized to victims and their descendants for its own failure to pass legislation.¹ The apology carried no legal force. Another 17 years passed before the Emmett Till Antilynching Act became law.
