Fred Hampton (August 30, 1948 - December 4, 1969) was an African-American activist and revolutionary, chairman of the Illinois chapter of the Black Panther Party (BPP), and deputy chairman of the national BPP. Hampton and fellow Black Panther Mark Clark were killed during a raid by a tactical unit of the Cook County, Illinois State's Attorney's Office, in conjunction with the Chicago Police Department and the Federal Bureau of Investigation in December 1969. In January 1970, a coroner's jury held an inquest and ruled the deaths of Hampton and Clark to be justifiable homicide. However, a civil lawsuit was later filed on behalf of the survivors and the relatives of Hampton and Clark.

According to a 1969 Chicago Tribune report, "The raid ended the promising political career of Cook County State's Atty. Edward V. Hanrahan, who was indicted but cleared with 13 other law-enforcement agents on charges of obstructing justice. Bernard Carey, a Republican, defeated him in the next election, in part because of the support of outraged black voters." The families of Hampton and Clark filed a US$47.7 million civil suit against the city, state, and federal governments. The case went to trial before Federal Judge J. Sam Perry. After more than 18 months of testimony and at the close of the Plaintiff's case, Judge Perry dismissed the case. The Plaintiffs appealed and the U.S. Court of Appeals for the Seventh Circuit reversed, ordering the case to be retried. More than a decade after the case had been filed, the suit was finally settled for $1.85 Million. The two families each shared in the settlement. Jeffrey Haas, who, together with his law partners G. Flint Taylor and Dennis Cunningham and attorney James D. Montgomery, were the attorneys for the plaintiffs in the federal suit Hampton v. Hanrahan, wrote in his book about Hampton's death that Chicago was worse off without Hampton: Of course, there's also the legacy that, without a young leader, I think the West Side of Chicago degenerated a lot into drugs. And without leaders like Fred Hampton, I think the gangs and the drugs became much more prevalent on the West Side. He was an alternative to that. He talked about serving the community, talked about breakfast programs, educating the people, community control of police. So I think that that's unfortunately another legacy of Fred's murder. In 1990, the Chicago City Council unanimously passed a resolution, introduced by then-Alderman Madeline Haithcock, commemorating December 4, 2004, as "Fred Hampton Day in Chicago". The resolution read in part: "Fred Hampton, who was only 21 years old, made his mark in Chicago history not so much by his death as by the heroic efforts of his life and by his goals of empowering the most oppressed sector of Chicago's Black community, bringing people into political life through participation in their own freedom fighting organization."
