The immigration restrictions of the 1920s were introduced because of the nativist belief that northern Europeans were superior to southern and eastern Europeans. This belief was based on the idea of eugenics, which held that certain races were biologically superior to others. The Immigration Act of 1924 established a quota system based on national origin, which restricted the number of immigrants from southern and eastern Europe. The act was supported by many Americans who believed that the influx of immigrants was responsible for urban overcrowding and crime.
