ACLU
The American Civil Liberties Union (ACLU) is a nonprofit organization in the United States focused on defending and preserving individual rights and liberties guaranteed by the United States Constitution and federal law. Founded in 1920, the ACLU has played a central role in litigating and campaigning on issues such as freedom of speech, equal protection, due process, and separation of church and state, making it a pivotal institution in the Civil rights movement and broader struggles for civil liberties.
The ACLU was established in 1920 by a coalition including Roger Nash Baldwin, Crystal Eastman, and Albert DeSilver, in response to wartime civil liberties restrictions like the Espionage Act of 1917 and the Sedition Act. Early work included defending freedom of speech for dissenting writers and labor activists and challenging government surveillance and deportations during the First Red Scare. During the 1920s and 1930s the ACLU engaged in cases involving the Scopes Trial era controversies over academic freedom and church–state separation. Throughout the 1940s and 1950s the organization expanded its litigation program and began to litigate civil liberties claims under the Fourteenth Amendment and federal statutes, positioning itself to play a major role in mid‑20th century civil rights litigation.
During the mid‑20th century, the ACLU worked alongside organizations such as the National Association for the Advancement of Colored People (NAACP) and civil rights lawyers including Thurgood Marshall to challenge segregation and discriminatory laws. The ACLU filed amicus briefs and represented plaintiffs in cases addressing voting rights, public accommodations, and school desegregation. Although the NAACP Legal Defense Fund led many landmark racial equality cases, the ACLU contributed legal resources, public advocacy, and support for activists during the Montgomery Bus Boycott and the broader Civil Rights Movement. The organization also defended civil liberties for civil rights demonstrators and challenged state and local efforts to suppress protest and free assembly.
The ACLU uses litigation, amicus briefs, legislative advocacy, and public education. Notable constitutional strategies include invoking the First Amendment for speech and religious liberty claims, and the Fourteenth Amendment for equal protection and due process challenges. Landmark cases involving the ACLU or its affiliates include challenges to school prayer and religious displays, defense of controversial speech in cases resembling the precedents of Brandenburg v. Ohio and New York Times Co. v. Sullivan‑era law, and litigation on criminal procedure rights related to Miranda v. Arizona principles. The ACLU has been involved in cases on racial discrimination, voting rights, Reproductive rights (notably matters connected to Roe v. Wade precedents), and modern privacy and surveillance issues implicating the Fourth Amendment.
Free speech and civil liberties are core ACLU priorities. The organization has defended unpopular or extremist speech to uphold broad First Amendment protections, litigating on behalf of protesters, journalists, and religious minorities. The ACLU has also campaigned on digital privacy and mass surveillance, opposing warrantless surveillance programs and advocating reforms to the USA PATRIOT Act. In education, the ACLU has argued for academic freedom, the rights of students and teachers under the Establishment Clause, and protections for LGBTQ+ students and staff consistent with Title IX and equal protection jurisprudence.
The ACLU's defense of absolute free‑speech principles has sometimes produced controversy. Critics have faulted the organization for defending the speech rights of extremist groups, claiming it affords legitimacy to hateful ideologies. Internally, the ACLU has faced disputes over strategic priorities, including tensions between civil liberties absolutism and commitments to racial justice and economic equality. Funding sources and partnerships occasionally attract scrutiny from political opponents who argue advocacy positions reflect ideological bias. The organization has periodically adjusted policies (for example on hate speech defense and selective litigation) in response to public criticism and evolving civil‑rights debates.
The ACLU operates through a national office and a network of state affiliates coordinated with the ACLU Foundation, a 501(c)(3) public charity that conducts litigation and education. Governance includes a national board of directors and executive leadership; notable leaders have included Anthony Romero and recent presidents such as Susan Herman and current president Deborah Archer. Funding comes from private donations, grants, and membership dues; the ACLU declines government funding for legal activities to preserve independence. The organization also receives support from philanthropic foundations and engages in targeted fundraising for litigation campaigns.
Over a century, the ACLU has shaped constitutional doctrine, protected dissent, and expanded interpretation of civil liberties across issues from racial equality and voting rights to privacy and LGBTQ+ protections. Its litigation strategy and public advocacy influenced major Supreme Court jurisprudence and legislative debates, contributing to the erosion of legalized segregation and the expansion of individual rights. While debates about tactics and priorities persist, the ACLU remains a consequential institution in American public life and a continuing force in legal battles over the balance between government authority and individual freedoms, alongside other actors such as the NAACP Legal Defense and Educational Fund, civil rights organizations, and public interest law firms.
