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.
Presidency of Woodrow Wilson
Prohibition developed as an unstoppable reform during the war, but Wilson played a only minor role in its passage. A combination of the temperance movement, hatred of everything German (including beer and saloons), and activism by churches and women led to ratification of an amendment to achieve Prohibition in the United States. A Constitutional amendment passed both houses in December 1917 by 2/3 votes. By January 16, 1919, the Eighteenth Amendment had been ratified by 36 of the 48 states it needed. On October 28, 1919, Congress passed enabling legislation, the Volstead Act, to enforce the Eighteenth Amendment. Wilson felt Prohibition was unenforceable, but his veto of the Volstead Act was overridden by Congress. Prohibition began on January 16, 1920; the manufacture, importation, sale, and transport of alcohol were prohibited, except in specific cases (such as wine used for religious purposes).
