The Eighteenth Amendment to the United States Constitution, ratified in 1919, established the prohibition of alcohol. This amendment made it illegal to manufacture, sell, or transport alcoholic beverages in the U.S. The goal was to reduce crime and corruption, improve health, and strengthen families. However, the Eighteenth Amendment led to unintended consequences, including the rise of illegal activities and organized crime, as people sought ways to obtain alcohol. The amendment was eventually repealed by the Twenty-first Amendment in 1933, marking the end of Prohibition and restoring the legal status of alcohol in the country.
