What Were Some Examples of American Nativism in the 1920s?

Some examples of American nativism in the 1920s were the resurgence of the Ku Klux Klan and its growth in the northern states, the emergence of the eugenics movement and an interest in racial purity prompted by the publication of Madison Grant's book "The Passing of the Great Race" and the enactment of legislation designed to significantly limit immigration. Following the end of Word War I, American nativists were strongly opposed to the influx of immigrants arriving from the war-torn European countries. Most of the attention was focused on the immigration of southeastern Europeans, Catholics and Jews.

By the end of the 1920s, immigration was reduced from 800,000 down to a strict limit of 150,000 per year. Immigration laws were influenced by author Madison Grant's warnings that the racial stock of the United States was being diluted by the arrival of people from the Polish ghettos, the Balkans and the Mediterranean region.

Originally formed to curtail the assimilation of African-Americans into society during the Reconstruction era, the Ku Klux Klan of the 1920s began targeting immigrants, Catholics, Jews and anyone the organization did not consider as representative of their view of the traditional American way of life.
