What was the duration of the Prohibition era in the United States?

The Prohibition era in the United States lasted from 1920 to 1933. This period was marked by the enactment of the 18th Amendment to the Constitution, which prohibited the manufacture, sale, and transportation of alcoholic beverages. The aim of Prohibition was to reduce crime and corruption, improve health, and boost the economy. However, this led to unintended consequences, including the rise of illegal speakeasies, bootlegging operations, and organized crime.

The time frame from 1920 to 1933 not only signifies the legal enforcement of Prohibition but also its eventual repeal with the ratification of the 21st Amendment in December 1933. This repeal marked the end of what was one of the most significant social experiments in American history. The other time frames presented do not correlate with the official start and end dates of Prohibition, making them incorrect.
