In the 1920s, racist attitudes towards immigrants in the United States worsened due to a growing fear of communism and bolshevism following the Russian Revolution. Two Italian immigrants, Nicola Sacco and Bartolomeo Vanzetti, were arrested in 1920 for robbery and murder due to suspicions of being anarchists. In response to fears of radicals, the U.S. government restricted immigration through new laws in 1924. Black Americans also faced discrimination and intimidation from the revived Ku Klux Klan movement while some were starting to find more opportunities in business and education in cities, though many still lived in poverty and faced violence.
