What group saw a revival in membership due to nativism?

The Ku Klux Klan experienced a revival in membership during the 1920s due to the rise of nativism in the United States. This period saw a growing sentiment against immigrants and a push for a so-called "pure" American identity, which the Klan capitalized on by promoting white supremacy and anti-immigrant rhetoric. Their influence expanded beyond the South, attracting members from various regions who resonated with their nativist agenda.
