1924 US Immigration Act – country based immigration quotas

> The ultimate goal of the immigration act according to the U.S. Department of State Office of the Historian was "to preserve the ideal of American homogeneity" and preserve racial homogeneity.

Interestingly it not only restricted the immigration of Africans and banned the immigration of Arabs and Asians but also restricted immigration of Southern Europeans and Eastern Europeans (especially Italians and Eastern European Jews).
