How did Madison Grant see these newer immigrant groups endangering America?

Madison Grant viewed newer immigrant groups, particularly those from Southern and Eastern Europe, as a threat to the racial and cultural integrity of America. He believed that these immigrants were racially inferior and would undermine the nation’s social fabric, leading to a decline in its Anglo-Saxon heritage. Grant argued that their arrival would result in increased crime, poverty, and a dilution of American values, which he believed were rooted in a predominantly Nordic population. His views were influential in shaping early 20th-century Immigration policies and eugenics movements.
