What was the fear of foreigners during the 1920?

The fear of foreigners during the 1920s, often referred to as xenophobia, was largely fueled by rising nationalism and economic concerns following World War I. Many Americans viewed immigrants as potential threats to jobs, cultural values, and national security, exacerbated by the Red Scare and a belief that immigrants might bring radical ideas. This culminated in restrictive Immigration laws, such as the Immigration Act of 1924, which aimed to limit the influx of immigrants from certain countries, particularly Southern and Eastern Europe. The era was marked by a desire to preserve a homogeneous American identity amidst rapid social and demographic changes.
