What was the goal of the origins act of 1924?

The Immigration Act of 1924, also known as the Johnson-Reed Act, aimed to significantly reduce immigration from Southern and Eastern Europe, as well as prohibit immigration from Asia. It established a quota system based on national origins, favoring immigrants from Northern and Western Europe. The act reflected the nativist and xenophobic sentiments of the time, promoting a vision of American homogeneity while limiting the influx of diverse populations. Ultimately, it sought to preserve the existing demographic composition of the United States.
