In what year did the 18th Amendment take effect in the United States?

The correct year when the 18th Amendment took effect is 1920. This amendment, which prohibited the manufacture, sale, and transportation of alcoholic beverages, was ratified in 1919. However, it did not become law immediately. The amendment took effect one year later, on January 17, 1920. This marked the beginning of Prohibition in the United States, which aimed to eliminate alcohol consumption and its associated societal issues. The Volstead Act was passed in 1919 to provide for the enforcement of Prohibition, but the actual enforcement and impact were seen starting in 1920. This period would later lead to significant social and political consequences that shaped American culture throughout the 1920s and beyond.
