American Civil Liberties Union [SEP] Overview
The ACLU was founded in 1920 by a committee including Helen Keller, Roger Nash Baldwin, Crystal Eastman, Walter Nelles, Morris Ernst, Albert DeSilver, Arthur Garfield Hays, Jane Addams, Felix Frankfurter, Elizabeth Gurley Flynn, and Rose Schneiderman. Its focus was on freedom of speech, primarily for anti-war protesters. It was founded in response to the controversial Palmer raids, which saw thousands of radicals arrested in matters which violated their constitutional search and seizures protection. During the 1920s, the ACLU expanded its scope to include protecting the free speech rights of artists and striking workers, and working with the National Association for the Advancement of Colored People (NAACP) to decrease racism and discrimination.
