When people talk about suing police officers, jail staff, school officials, or other government actors for violating constitutional rights, they are often talking about Section 1983. It is one of the main federal legal tools used in civil rights litigation, and it shows up in cases involving excessive force, wrongful arrest, jail abuse, fabricated evidence, retaliation, and many other forms of state or local government misconduct.
In plain language, Section 1983 is the statute that lets a person bring a civil claim when someone acting under state or local authority deprives them of rights protected by the U.S. Constitution or federal law. The statute itself is short, but the law around it is anything but simple. Courts have spent decades defining who counts as a proper defendant, what rights are actionable, what immunities may apply, and when a city or county can be held responsible.
If you’re trying to understand the bigger picture, it may help to start with this broader guide to civil rights claims involving police misconduct and government accountability. In this post, you’ll get a focused explanation of Section 1983 itself: what it is, where it came from, what it covers, what it does not cover, and why attorney fit can matter so much in these cases.

Section 1983 refers to 42 U.S.C. § 1983, a Reconstruction-era federal statute originally derived from the Ku Klux Klan Act of 1871. The law creates a civil cause of action against a “person” who, under color of state law, deprives someone of rights secured by the Constitution or federal law. The statute itself does not create the underlying rights; instead, it provides a way to seek redress when rights from other sources, such as the Fourth, Eighth, or Fourteenth Amendments, are violated.
That distinction matters. Section 1983 is often described as a vehicle for enforcing federal rights, not the source of those rights. The Supreme Court has repeatedly treated it that way, and judicial resources on Section 1983 emphasize the same framework, including the Federal Judicial Center’s Section 1983 litigation materials and the Ninth Circuit’s updated Section 1983 outline.
Section 1983 emerged after the Civil War during Reconstruction, when Congress sought a federal remedy against abuses carried out under state authority, especially where local systems were unwilling or unable to protect constitutional rights. The Federal Judicial Center’s history of prison and civil rights litigation notes that the statute traces back to the Ku Klux Klan Act of 1871 and later became a major mechanism for suits against state officials after the Supreme Court interpreted “under color of state law” broadly in Monroe v. Pape.
That history helps explain why Section 1983 remains central today. Many of the most important constitutional rights people assert against police departments, correctional systems, municipalities, and public schools are enforced through this statute.
At a high level, a Section 1983 claim usually involves two core elements:
Those basic elements sound simple, but each one can generate extensive litigation.

“Under color of state law” generally refers to conduct tied to government authority. Police officers on duty are the most familiar example, but Section 1983 can also apply to sheriffs, jail officers, public school officials, social workers, municipal employees, and other state or local actors when they are using or misusing official power.
