Intolerance in the 1920s
To keep the "true" American values, intolerance was displayed by restrictive legislation and violence. Immigrants from Northern and Western Europe became targets of those acts. Socialists and Atheists were also victims. Americans wanted them to conform with the rest.
To decrease the immigrant population, a literacy test was imposed in 1917, but approximately 1.25 million immigrants entered the United States in the first two years of the 1920s. Because of this, the government put a cap on the number of immigrants allowed into the United States. Then in 1924, the National Origins Act based immigrant admission on nationality. Immigrants from northern and western Europe had a higher quota compared to others while Asian immigrants were banned.
