Immigration Restriction League

The Immigration Restriction League was an American nativist and anti-immigration organization founded by Charles Warren, Robert DeCourcy Ward, and Prescott F. Hall in 1894. According to Erika Lee, in 1894 the old stock Yankee upper-class founders of the League were "convinced that Anglo-Saxon traditions, peoples, and culture were being drowned in a flood of racially inferior foreigners from Southern and Eastern Europe." Established during a period of increasing anti-immigration sentiment in the United States, the League was founded by Boston Brahmins such as Henry Cabot Lodge with the purpose of preventing immigrants from Eastern Europe and Southern Europe from immigrating to the US due to a belief that they were racially inferior to Northern Europeans and Western Europeans.
