How did isolationist beliefs affect immigration policy during 1920s?

Is nativism similar to isolationism? I only know how the nativist sentiment affected the immigration policy, but I don't know about the isolationist beliefs. Please explain. THANKS A LOT!

Isolationism is the policy that the country should basically ignore other countries and not get involved with their problems. After World War I, many Americans embraced isolationism to avoid being involved in another war with other countries. Geographically, America is isolated from the rest of the world; isolationism demanded that we remain economically and militarily isolated from Europe, Africa, and Asia.

Nativism means that the country wanted only "real" Americans here. For many people, that meant keeping out foreigners.

so, go back to the actual question,how did isolationist beliefs affect immigration policy during 1920s?

Please give me some ideas!THANKS!

Americans believed they had a great country. The isolationists didn't want to be involved with the rest of the world. Obviously, that also meant that they didn't want people from other countries here. Nativism (keeping the U.S. for Americans) went hand-in-hand with isolationism.

During the 1920s, isolationist beliefs had a significant impact on immigration policy in the United States. Isolationism refers to the belief and policy of non-intervention in foreign affairs, with a focus on protecting and preserving national interests.

The isolationist sentiment in the 1920s was partly a reaction to the devastating effects of World War I and a desire to avoid further involvement in international conflicts. This sentiment influenced immigration policy by promoting a more restrictive approach towards immigration.

Firstly, the Immigration Act of 1921, also known as the Emergency Quota Act, was passed in response to growing concerns about the influx of immigrants and the fear that they may pose a threat to American jobs and culture. This act established the first numerical quota system for immigration, limiting the number of immigrants accepted from each country based on a percentage of their population in the United States as of the 1910 census. The act effectively favored immigrants from Northern and Western Europe, as countries with larger populations in 1910 were given higher quotas.

Secondly, the Immigration Act of 1924, also called the Johnson-Reed Act, further restricted immigration. This act revised the quota system by shifting the reference year from 1910 to 1890, which favored immigrants from older-established groups and severely limited the number of immigrants from countries that had seen significant immigration in the previous decades, primarily from Southern and Eastern Europe. The goal was to preserve what many Americans deemed as "traditional American values" by reducing the number of immigrants from these regions who were considered culturally and ethnically different.

Now, let's address your question about nativism. Nativism refers to a political and social mindset that promotes and protects the interests of native-born citizens against those of immigrants. While there is an overlap between nativism and isolationism in terms of concerns about protecting national interests, they are not entirely identical concepts.

Nativist sentiments, rooted in xenophobia and a fear of losing political and economic power to immigrants, played a significant role in shaping immigration policy during the 1920s. The proponents of nativism advocated for immigration restrictions based on the belief that immigrants posed a threat to American society, culture, and economy. Their concerns were primarily about immigrants from Southern and Eastern Europe, as well as non-European immigrants.

In summary, isolationist beliefs in the 1920s influenced immigration policy by promoting a more restrictive approach. This led to the establishment of the quota system through the Immigration Acts of 1921 and 1924, which aimed to limit immigration and disproportionately favored immigrants from Northern and Western Europe. Nativist sentiments, although related, are not synonymous with isolationism but contributed to the push for immigration restrictions by focusing on protecting the interests of native-born citizens against those of immigrants.
