Prohibition in the United States
Research shows that prohibition reduced overall alcohol consumption by half during the 1920s, and consumption remained below pre-Prohibition levels until the 1940s, suggesting that Prohibition did socialize a significant proportion of the population in temperate habits, at least temporarily. Rates of liver cirrhosis "fell by 50% early in Prohibition and recovered promptly after Repeal in 1933." Criticism remains that Prohibition led to unintended consequences such as a century of Prohibition-influenced legislation and the growth of urban crime organizations, though some scholars have argued that violent crime did not increase dramatically, while others have argued that crime during the Prohibition era was properly attributed to increased urbanization, rather than the criminalization of alcohol use. As an experiment it lost supporters every year, and lost tax revenue that governments needed when the Great Depression began in 1929.
History of the United States (1918–1945)
In 1920, the manufacture, sale, import and export of alcohol was prohibited by the Eighteenth Amendment to the United States Constitution in an attempt to alleviate high rates of alcoholism and, especially, political corruption led by saloon-based politicians. It was enforced at the federal level by the Volstead Act. Most states let the federals do the enforcing. Drinking or owning liquor was not illegal, only the manufacture or sale. National Prohibition ended in 1933, although it continued for a while in some states. Prohibition is considered by most (but not all) historians to have been a failure because organized crime was strengthened.
