Imagine learning that your government once ran secret campaigns to disrupt lawful political groups, using forged letters, planted rumors, and informants. That is not a movie plot. It is the documented story of COINTELPRO, and understanding what COINTELPRO was helps explain why Americans still argue about security, surveillance, and trust.
Quick answer: COINTELPRO (short for Counterintelligence Program) was a set of covert FBI operations from 1956 to 1971 aimed at surveilling, discrediting, and disrupting domestic political groups, including the Communist Party, the Ku Klux Klan, civil rights organizations, Black nationalist groups, and antiwar activists. It was exposed in 1971 and investigated by Congress in the mid-1970s, leading to reforms.
What was COINTELPRO?
COINTELPRO was not one program but a series of them. The FBI launched the first in 1956, targeting the Communist Party USA. Over the next fifteen years, it added programs aimed at other groups the Bureau viewed as threats.
The word “counterintelligence” normally refers to stopping foreign spies. COINTELPRO turned those methods inward. Instead of gathering evidence for prosecution, agents often worked to weaken groups through secret, unofficial means, even when the groups were engaged in lawful speech and organizing.
The main programs at a glance
| Program (approximate start) | Main targets |
|---|---|
| Communist Party USA (1956) | The Communist Party and related organizations |
| Socialist Workers Party (1961) | A small socialist political party |
| White Hate Groups (1964) | The Ku Klux Klan and other white supremacist organizations |
| Black Nationalist-Hate Groups (1967) | Civil rights and Black nationalist organizations and leaders |
| New Left (1968) | Antiwar, student, and other left-leaning groups |
Note that one program did target violent white supremacists. Most of the effort and the most controversial examples, however, involved groups engaged in political dissent.
Why did it start? The Cold War context
To understand any government program, it helps to ask what problem its creators believed they were solving. In the 1950s, the United States and the Soviet Union were locked in the Cold War. Soviet espionage was real, and fear of infiltration shaped politics, as covered in our guide to American history that explains today.
FBI Director J. Edgar Hoover, who led the Bureau for nearly fifty years, was convinced that communism threatened the country. When prosecutions proved difficult, because speech and association are protected by the First Amendment, the Bureau looked for other ways to act. COINTELPRO was the result.
This is the central pattern worth noticing. An agency with a mission, little outside oversight, and a belief that the stakes were enormous can drift from enforcing the law to deciding what it thinks is best for the country. The people involved often believed they were protecting America.
What did COINTELPRO actually do?
Documents released later show a range of tactics. Some were ordinary investigation. Many were not.
- Surveillance: wiretaps, bugs, mail opening, and networks of informants.
- Forged and anonymous letters: sent to sow distrust between group members, spouses, or allies.
- Leaking damaging information: passing rumors or private details to reporters and employers.
- Infiltration and provocation: placing informants inside groups, some of whom encouraged conflict or illegal acts.
- Harassment: pressuring landlords, employers, and funders to cut ties with targets.
The goal, as the Bureau’s own memos described it in language later quoted by investigators, was to “disrupt” and “neutralize” groups. That is a very different goal from solving crimes.
Who was targeted?
Civil rights leaders and organizations
The most widely discussed example is the FBI’s surveillance and harassment of Dr. Martin Luther King Jr. The Bureau wiretapped him, collected information on his private life, and in 1964 mailed him an anonymous letter that many historians read as an attempt to push him toward suicide. Hoover viewed King as a dangerous figure, though investigators never established that he was a threat to national security. King’s activism was part of the broader history of voting rights in America, a context that helps explain why the FBI viewed him as a threat.
The Black Panther Party
The Bureau also targeted the Black Panther Party, which Hoover once called a leading threat to internal security. FBI efforts included informants, forged materials meant to inflame rivalries, and cooperation with local police. The Party’s own record is complicated, with community programs alongside armed confrontations and internal violence. Our article on the history of the Black Panther Party looks at both sides. The 1969 killing of Chicago Panther leader Fred Hampton during a police raid has been closely examined, with the FBI’s role as an informant source a documented part of the story.
The Klan, socialists, and the antiwar movement
COINTELPRO was not aimed only at one side of the political spectrum. The Bureau ran a program against the Ku Klux Klan that disrupted violent groups. But the Socialist Workers Party, student groups, and antiwar organizations were also targeted despite being largely lawful, and the civil rights programs received much of the later criticism.
When an agency decides which lawful ideas are too dangerous to tolerate, every citizen’s freedom to disagree is at stake.
How was it exposed?
For years, almost no one outside the Bureau knew COINTELPRO existed. That changed on the night of March 8, 1971, when a group calling itself the Citizens’ Commission to Investigate the FBI broke into a small FBI office in Media, Pennsylvania. They took files and mailed copies to newspapers.
Among the papers was a routine-looking document with the word COINTELPRO on it. Journalists reported on it, and in the following months additional documents emerged, including through Freedom of Information Act requests from other researchers. The FBI formally ended the programs in April 1971, though it argued some activities should continue in other forms.
Notice what made this possible: a free press willing to publish, and ordinary citizens willing to take risks. It is a good example of the points in our media literacy guide about how information reaches the public.
The Church Committee and the reforms that followed
In 1975, the U.S. Senate created a special panel chaired by Senator Frank Church to investigate intelligence agencies. The Church Committee held public hearings and issued detailed reports in 1975 and 1976. It concluded that COINTELPRO had gone well beyond lawful investigation and had violated the rights of Americans.
The findings contributed to a series of reforms in the late 1970s, including:
- Attorney General guidelines limiting when the FBI can open domestic investigations.
- Permanent congressional intelligence committees to provide ongoing oversight.
- The Foreign Intelligence Surveillance Act (FISA) of 1978, which created a court to review certain surveillance requests.
This is a good illustration of separation of powers at work. Congress investigated the executive branch and then wrote new rules to constrain it. The rules themselves have been revised many times since, so check current official sources such as the Department of Justice for what applies today.
How do people interpret COINTELPRO?
Historians agree on the basic documented facts. Where people differ is in interpretation and values. Here are the strongest versions of the main perspectives.
The “abuse of power” view
Critics argue that COINTELPRO shows what happens when a powerful agency operates in secret. They point out that many targets were engaged in protected speech, that the Bureau sometimes acted on political or personal animus, and that the damage to individuals and movements was real. On this view, the lesson is that strong, independent oversight is essential in any era.
The “security in context” view
Others emphasize that officials faced real threats: Soviet espionage, and in the late 1960s and early 1970s a wave of bombings and violence by some radical groups. They argue that agents were responding to genuine dangers and that some programs, like those aimed at the Klan, were justified. On this view, the failure was not the goal of protecting the country but the lack of clear legal limits on methods.
Where the evidence points
The documentary record, including the Bureau’s own files, supports the conclusion that many tactics were unlawful and that lawful political activity was targeted. Both of the perspectives above can accept that. The deeper disagreement is about values: how much risk a free society should tolerate in order to protect liberty, and who should decide.
Security and liberty are not enemies, but balancing them takes oversight, transparency, and citizens willing to ask hard questions.
Why COINTELPRO still matters
COINTELPRO connects to many other chapters of American life. Questions about who has power in America and how it is checked run straight through this history. So do debates over modern surveillance, protest policing, and informants, which we will explore further in our upcoming guide to the history of policing in America.
The story is also a reminder of how fragile constitutional protections can be. The Bill of Rights protects speech, assembly, and privacy, but those protections only work when institutions respect them and citizens notice when they do not.
Finally, it is a story about trust. Historians note that the revelations deepened public skepticism of government in the 1970s, a skepticism that still shapes politics on the left and right. Understanding the history can help us talk about it honestly. Our guide on how to talk about politics with family offers practical ways to do that without the shouting.
Think about it: If you were designing oversight for a powerful security agency, what rules would you want in place so that it could stop real threats without targeting lawful dissent? Would your answer change if the people being watched were from a political group you disagree with?

Frequently asked questions
What does COINTELPRO stand for?
COINTELPRO is short for Counterintelligence Program. The FBI used the term for a series of covert operations that began in 1956. Counterintelligence normally means catching foreign spies, but these programs were aimed at domestic groups and individuals.
Was COINTELPRO legal?
Many of its tactics were illegal or violated constitutional protections, including burglaries, wiretaps without proper authority, and interference with free speech and association. The Church Committee and later investigations concluded that the programs went well beyond lawful investigation. Courts and Congress later imposed new limits, though historians debate how durable those limits are.
Who did COINTELPRO target?
Targets included the Communist Party USA, white supremacist groups like the Ku Klux Klan, the Socialist Workers Party, civil rights organizations and leaders, Black nationalist groups, the Black Panther Party, and parts of the antiwar and New Left movements. Most of the programs, and most of the documented effort, focused on left-leaning and civil rights groups—a pattern that reflected and reinforced the political realignment of the era.
How did the public find out about COINTELPRO?
In March 1971, a group calling itself the Citizens’ Commission to Investigate the FBI broke into an FBI office in Media, Pennsylvania, and mailed stolen files to journalists. The documents revealed the program’s name and methods. Later press reports, lawsuits, and the Church Committee’s investigations in the mid-1970s exposed much more.
Does COINTELPRO still exist?
The FBI formally ended the programs in 1971, and reforms followed in the 1970s. Whether similar practices have reappeared is debated. Oversight bodies and inspectors general have documented later problems with surveillance and investigations. For the current rules governing FBI activity, check official sources such as the Department of Justice and FBI websites.
