American Protective League

The American Protective League was a private organization formed during World War I, comprising mostly of patriotic citizens and business allies. Its primary role was to assist government authorities in identifying and monitoring individuals suspected of disloyalty or anti-war activities, particularly targeting German-Americans. While it aimed to promote patriotism, its methods often involved surveillance, social pressure, and violation of privacy rights, leading to criticism for overreach. The League operated between 1917 and 1919, reflecting wartime efforts to maintain national security but also raising concerns about civil liberties.
