The American Civil Liberties Union

Since 1920, the ACLU has been the nation's guardian of liberty, working daily in courts, legislatures and communities to defend and preserve the individual rights and liberties that the Constitution and laws of the United States guarantee everyone in this country. The ACLU is best known for litigation efforts as the country’s largest public interest law organization; many of the ACLU’s ground-breaking cases have changed lives and made history.
