Final answer:
The Emergency Quota Law of 1921 was a nativist policy that aimed to restrict immigration by establishing quotas based on nationality.
Step-by-step explanation:
The enactment of a nativist policy that aimed to restrict immigration can be seen in the Emergency Quota Law of 1921. This law was implemented to temporarily limit the number of newcomers who might compete for jobs. It established quotas based on nationality, restricting immigration from non-Western European countries. An example of a nativist policy that was enacted into law is the National Origin Formula, which was established by the Emergency Quota Act of 1921 and further solidified by the Immigration Act of 1924. These laws aimed to restrict immigration significantly by imposing quotas that favored immigrants from certain Western European countries, reflecting the nativist desire to preserve a white, Anglo-Saxon, Protestant majority in America. It was a response to the high levels of immigration from Southern and Eastern Europe, and the perceived threat to American jobs and social order. This formula remained in effect until it was overturned by the Immigration and Nationality Act of 1965, which sought to eliminate race-based and nation-based discrimination in immigration policies. During the 1920s, nativism influenced America’s immigration policy by leading to the passage of laws that discriminated against certain immigrant groups, primarily targeting those who were nonwhite or non-Protestants. The nativist organizations such as the American Protective Association and the Immigration Restriction League played a crucial role in cultivating xenophobic sentiments and fostering legislative action aimed at limiting the immigration of these demographics.
