Final answer:
Nativists sought to stop immigration from Asia, supported by laws like the Chinese Exclusion Act and the National Origins Act of 1924, which established quotas and effectively banned Asians and limited 'new' immigrants from Europe.
Step-by-step explanation:
Nativists believed that all immigration from Asia had to be stopped. This sentiment was prevalent in the late nineteenth and early twentieth centuries, particularly in the United States. Nativists, who were often native-born Protestants of northern European ancestry, aimed to protect their vision of a white, Anglo-Saxon, and Protestant America. They supported measures such as the Chinese Exclusion Act of 1882 and later the National Origins Act of 1924, which both aimed to curb the immigration of nonwhite, non-Protestant, Jews, and other groups perceived as different from the established American populace.
The National Origins Act of 1924 was specifically designed to limit immigration from southern and eastern Europe, with a particularly harsh stance against Asians, by setting quotas on the number of immigrants based on the nationalities' representation in the 1890 census and excluding any group ineligible for citizenship.
