The Eighteenth Amendment remains the only constitutional change in American history to be repealed.

In short: Prohibition was intended to cure poverty and social ills by banning the sale of alcohol. Instead, it birthed a massive underground economy, empowered organized crime syndicates, and led to thousands of deaths from poisoned industrial alcohol. It stands as a singular, failed experiment in constitutional social engineering.

Proposed by Congress in December 1917 and ratified in January 1919, the Eighteenth Amendment prohibited the manufacture, sale, and transportation of intoxicating liquors. It was the culmination of decades of campaigning by the temperance movement, led by groups like the Anti-Saloon League and the Woman's Christian Temperance Union. Supporters argued that banning alcohol would eliminate poverty, reduce workplace accidents, and foster happier families. By 1916, nearly half of all states had already enacted some form of prohibition, setting the stage for a nationwide mandate.

The reality of Prohibition, which began on January 17, 1920, diverged sharply from its proponents' vision. While alcohol consumption initially declined, the Volstead Act—the federal enforcement legislation—struggled to contain the illicit trade. Bootlegging and speakeasies flourished, often supplied by foreign distributors or through the diversion of denatured industrial alcohol. In a grim turn, the government ordered the poisoning of industrial alcohol to deter consumption, a program that resulted in an estimated 10,000 deaths. By the late 1920s, public support had cratered as the Great Depression highlighted the lost tax revenue and jobs associated with the ban.

Perhaps the most enduring legacy of the era was the professionalization of organized crime. Gangs like those led by Al Capone transformed into sophisticated enterprises, controlling everything from production to retail. These syndicates used violence to secure territories and expanded into gambling, narcotics, and labor racketeering. The homicide rate climbed from six per 100,000 people to nearly ten during the period. Recognizing the failure, Franklin D. Roosevelt campaigned on repeal, leading to the ratification of the Twenty-first Amendment on December 5, 1933. This remains the only time in American history that a constitutional amendment has been overturned.
