====== Eighteenth Amendment ======

The Eighteenth Amendment to the United States Constitution, ratified on 16 January 1919 and taking effect one year later, prohibited the manufacture, sale, and transportation of intoxicating liquors within the United States and its territories. It is the only constitutional amendment to have been subsequently repealed, a status achieved by the [[twenty-first-amendment|Twenty-First Amendment]] in 1933. The amendment did not criminalize the consumption or private possession of alcohol, but it provided the federal constitutional basis for the [[volstead-act|Volstead Act]], the legislation that defined enforcement mechanisms and set the threshold for what constituted an intoxicating beverage.

===== Background and Scope =====

The amendment emerged from decades of temperance advocacy, rooted in Protestant religious culture, public health concerns, and anxieties about urban immigrant communities and their drinking customs. The [[anti-saloon-league|Anti-Saloon League]] and the [[womens-christian-temperance-union|Women's Christian Temperance Union]] were among the most influential organizations driving the push for a constitutional remedy rather than relying on state-level laws, which varied widely and were subject to repeal. By the time the amendment passed Congress in December 1917, over half of U.S. states had already enacted some form of prohibition.

The fourteen-year period during which the Eighteenth Amendment was in force, commonly called [[prohibition|Prohibition]], produced significant and contested consequences. Alcohol consumption did decline, particularly in the early years. At the same time, black markets emerged rapidly, organized crime networks expanded, federal and local law enforcement capacity was strained, and widespread evasion of the law was documented across all economic classes. The degree to which Prohibition succeeded or failed - and on what terms success or failure should be measured - remains a subject of historical and policy debate.

===== Repeal =====

Support for the amendment eroded through the late 1920s and accelerated after the onset of the [[great-depression|Great Depression]], when arguments about lost tax revenue and employment gained traction alongside longstanding objections on civil liberties grounds. The Twenty-First Amendment was ratified on 5 December 1933, making the Eighteenth Amendment the only amendment ever repealed from the U.S. Constitution. The repeal returned authority over alcohol regulation primarily to the states, producing a patchwork of laws that persists in modified form today.

===== Consensus Status =====

There is broad historical consensus that Prohibition did not eliminate alcohol use and that it contributed to the growth of organized crime. Historians debate the extent and duration of its public health effects, its role in shaping federal law enforcement, and whether its social costs outweighed its benefits.

===== Viewpoints =====

  * **Prohibition was a failed experiment in government overreach** - Critics argue the amendment imposed a minority moral and religious preference on a pluralistic society, proved unenforceable, empowered criminal enterprises, and demonstrated the limits of using constitutional law to regulate personal behavior. [[eighteenth-amendment-overreach-viewpoint|Read this viewpoint.]]

  * **Prohibition achieved meaningful public health and social gains** - Defenders contend that alcohol consumption and associated harms - domestic violence, poverty, industrial accidents - declined measurably during the period, and that the amendment's failure was primarily a failure of political will and enforcement rather than of the policy's underlying rationale. [[eighteenth-amendment-public-health-viewpoint|Read this viewpoint.]]

  * **Prohibition reflects legitimate democratic exercise of constitutional authority** - Some legal and social conservatives argue that the amendment was a valid product of the democratic process, ratified by the required supermajority, and that its repeal does not retroactively delegitimize the will of the electorate that enacted it.

  * **Prohibition's legacy informs contemporary drug policy debates** - Analysts across the political spectrum draw on Prohibition as a case study when evaluating the prohibition of other substances, with differing conclusions about what lessons apply and which analogies hold.
