S. Res. 307, Senate Resolution establishing the Overman Committee, September 19, 1918

In 1918 the Senate authorized the formation of the Overman Committee, named after its chair, Senator Lee Slater Overman of North Carolina. The committee’s initial directive was to investigate the U.S. Brewers Association. Since German immigrants had largely founded the major brewing companies in the United States, some members of Congress had concerns that they might be involved in supporting pro-German activities.

Investigating "Un-American" Activities and Restricting Immigration

World War I led to widespread concerns and speculation regarding threats to national security and democracy. Fear of “un-American” activities in the United States prompted the Senate to form the Overman Committee in 1918, which investigated possible pro-German, Bolshevik, and other activities and propaganda deemed dangerous to the nation. Public concern about the ethnic composition in the country and competition from foreign workers, meanwhile, pressured Congress to pass several laws in the early 1920s that banned or significantly restricted the number of immigrants admitted to the United States.

The nation having engaged in the greatest war in history with the purpose of saving the world for democracy, now emerges from that struggle confronted with the paramount duty of preserving democracy for the world.

Until now we have proceeded upon the theory that America was “the refuge of the oppressed of all nations,” and we have indulged the belief that upon their arrival here all immigrants were fused by the “melting pot” into a distinctive American type.
