The document discusses why the 1920s in the United States came to be known as the "Age of Intolerance". Socially, the decade saw openly racist organizations like the Ku Klux Klan gain prominence. Politically, prohibition laws were enacted but did not achieve the desired results. As a result of social discrimination and political prohibitions, crime rose significantly during the 1920s as criminal organizations like those led by Al Capone exploited black markets. In conclusion, the label "Age of Intolerance" fits the 1920s due to the widespread social and political intolerance and rise in criminal activity during the decade.
