What did this mean for SCE (southern central and eastern) Europeans and Asians?

The period of the 1890s-1924 was the largest period of immigration in U.S. history, when more than 20,000,000 people arrived in the U.S. The period was also one of intensifying nativism and racism, as many Anglo Americans feared the arrival of the “unwashed masses,” people largely migrating from southern, eastern, and central Europe (SCE). Their detractors deemed them racially inferior—even if the Europeans were marginally “white.” More frightening were Asians, considered beyond the pale and incapable of assimilation. Many feared that SCEs and Asians would outbreed native-born whites, interbreed with whites and thus contaminate Anglo Saxon racial purity and, in either process, imperil the nations racial superiority—just as the United States was entering a new century and international prominence.
