A major cause of nativist attitudes during the 1920s was the fear of cultural and economic competition from immigrants. The United States experienced a significant influx of immigrants during this period, primarily from Southern and Eastern Europe, which led to concerns about the preservation of American values, identity, and prosperity. Many nativist Americans believed that these immigrants threatened the nation's stability and the jobs of American-born individuals. Additionally, the end of World War I intensified these fears, as returning soldiers faced increased competition for jobs and resources. The nativist sentiment culminated in the passage of restrictive immigration laws such as the Immigration Act of 1924, which significantly reduced the number of immigrants coming to the United States.
