The most significant factor contributing to the growth of nativist attitudes in the U.S. after World War I was the fear of Immigration, particularly from Southern and Eastern Europe. The war heightened concerns about national security and the perceived threat of radical ideologies, such as communism and anarchism, which many associated with immigrant populations. Economic instability and competition for jobs during the post-war recession further fueled resentment towards immigrants, leading to a rise in nativist sentiments and restrictive immigration policies.
