Young Lords in the context of Lincoln Park, Chicago

COINTELPRO (a syllabic abbreviation derived from Counter Intelligence Program) was a series of covert and illegal projects conducted between 1956 and 1971 by the United States Federal Bureau of Investigation (FBI) aimed at surveilling, infiltrating, discrediting, and disrupting American political parties and organizations that the FBI perceived as subversive.

Groups and individuals targeted by the FBI included feminist organizations, the Communist Party USA, anti-Vietnam War organizers, activists in the civil rights and Black power movements (e.g., Martin Luther King Jr., Malcolm X, and the Black Panther Party), Student organizations such as Students for a Democratic Society (SDS) and Student Nonviolent Coordinating Committee (SNCC), environmentalist and animal rights organizations, the American Indian Movement (AIM), Chicano and Mexican-American groups like the Brown Berets and the United Farm Workers, and independence movements (including Puerto Rican independence groups, such as the Young Lords and the Puerto Rican Socialist Party). Although the program primarily focused on organizations that were part of the broader New Left, they also targeted white supremacist groups, such as the Ku Klux Klan and the National States' Rights Party.

In Marxist theory, the Lumpenproletariat (German: [ˈlʊmpn̩pʁoletaʁi̯ˌaːt] ; /ˌlʌmpənproʊlɪˈtɛəriət/) is the underclass devoid of class consciousness. Karl Marx and Friedrich Engels coined the word in the 1840s and used it to refer to the unthinking lower strata of society exploited by reactionary and counter-revolutionary forces, particularly in the context of the revolutions of 1848. They dismissed the revolutionary potential of the Lumpenproletariat and contrasted it with the proletariat. Among other groups, criminals, vagabonds, and prostitutes are usually included in this category.

The Social Democratic Party of Germany made wide use of the term by the turn of the 20th century. Vladimir Lenin and Leon Trotsky followed Marx's arguments and dismissed the revolutionary potential of the group, while Mao Zedong argued that proper leadership could utilize it. The word Lumpenproletariat, popularized in the West by Frantz Fanon's The Wretched of the Earth in the 1960s, has been adopted as a sociological term. However, what some consider to be its vagueness and its history as a term of abuse has led to some criticism. Some revolutionary groups, most notably the Black Panther Party and the Young Lords, have sought to mobilize the Lumpenproletariat.
