Which factor resulted in passage of the immigration act of 1924?

The Immigration Act of 1924 was a federal law passed on May 16, 1924 to limit immigration. This law was much more restrictive than the Emergency Quota Act of 1921, and went further than the 1882 Chinese Exclusion Act by banning entry to the entire Chinese population and extending restrictions to other Asian immigrant groups, and to a lesser extent, to people from Eastern and Southern Europe; on the other hand, it did not apply to persons originating from the American continent.

The law was proposed in a context of strong xenophobia. Some of his most convinced followers were influenced by Madison Grant and his 1916 book, The Decline of the Great Race. Grant was a eugenicist and promoter of a racial hygiene theory designed to maintain the purity of the founding Nordic races because of their alleged superiority.
