1920's and Prohibition

  • Formation of the FBI (July 1, 1908, restructured in 1924)

    Although established earlier, the FBI evolved during the 1920s into a more powerful agency focused on enforcing Prohibition laws, particularly under J. Edgar Hoover.
  • 18th Amendment was ratified

    Prohibition officially began with ratifying the 18th Amendment, which prohibited the manufacture, sale, and transportation of alcoholic beverages.
  • Volstead Act

    This act provided for the enforcement of Prohibition, defining what constituted "intoxicating liquors" and outlining the legal framework for enforcement.
  • Rise of Speakeasies

    With legal alcohol banned, underground bars known as speakeasies emerged, becoming popular social hubs where people could drink illicitly.
  • Prohibition Begins

    The 18th Amendment came into effect, leading to the nationwide prohibition of alcohol.
  • The Scopes "Monkey" Trial (July 10-21)

    This trial in Tennessee highlighted the cultural clash between science and religion, reflecting the broader social tensions of the era.
  • The Jazz Age

    This period saw the rise in popularity of jazz music, fostering a cultural revolution that included figures like Louis Armstrong and Duke Ellington
  • St. Valentine's Day Massacre

    This infamous gangland killing in Chicago, involving the Capone gang, highlighted the violent crime associated with illegal alcohol distribution during Prohibition.
  • The Stock Market Crash

    While technically at the end of the decade, the crash marked the beginning of the Great Depression, which was influenced by the economic conditions of the 1920s.
  • Repeal of Prohibition

    Although this event technically falls outside the 1920s, it marked the end of the 13 years of Prohibition, demonstrating the public's disillusionment with the law.
