The revival of the KKK in the early twentieth century reflected a society struggling with the effects of
Industrialization, urbanization, and Immigration. Klan chapters in major urban areas expanded as many white
Americans became bitter and resentful about Immigration from Asia and Eastern Europe. Klansmen complained
that these Immigrants were taking jobs away from whites and diluting the imagined "racial purity of American
society, Given that the country had been populated by Immigrants from the beginning, such ideas of racial purity
were complete myths.
