Prohibition
On the timeline · around 1920–1933 ·
What happened
The Eighteenth Amendment and the Volstead Act banned the manufacture and sale of alcohol nationwide beginning in 1920. Instead of a sober society, Prohibition produced speakeasies, bootleggers, and powerful organized-crime syndicates, and it was repealed in 1933 — the only constitutional amendment ever undone by another.
Why it matters
Prohibition was a defining experiment of the era, revealing both the reforming zeal and the unintended consequences of trying to legislate morality, and it reshaped American law enforcement and organized crime.
