How is the red scare and national origins act related?

The Red Scare and the National Origins Act are related through their reflection of the prevailing fears and societal attitudes in the United States during the early 20th century. The Red Scare, particularly after World War I, was marked by a widespread fear of communism and radical leftism, leading to heightened suspicion of immigrants and leftist ideologies. The National Origins Act of 1924 established restrictive Immigration quotas aimed primarily at limiting the influx of immigrants from Southern and Eastern Europe, as well as Asia, which were viewed as potential sources of radicalism. Both phenomena illustrate the era's xenophobia and the desire to maintain a homogeneous national identity in response to perceived threats.
