Final answer:
Ellis Island and Angel Island were significant locations related to nativism in the United States during the late 1800s and early 1900s, as they were the primary immigration entry points influenced by nativist attitudes and policies.
Step-by-step explanation:
Some locations important to nativism in the late 1800s and early 1900s were Ellis Island and Angel Island. These were the main entry points for immigrants entering the United States, with Ellis Island serving primarily European immigrants and Angel Island serving mostly Asian immigrants. Nativist movements during this period, such as the American Protective Association and the Immigration Restriction League, aimed to limit the influx of certain ethnic groups into the country, advocating for laws like the literacy test and supporting acts like the Chinese Exclusion Act. Furthermore, nativism heavily influenced immigration policy, leading to the Emergency Quota Act of 1921 and the Immigration Act of 1924 which established quotas based on national origin.
