Prohibition and Repeal: The Eighteenth and Twenty-First Amendments

Introduction

The Eighteenth Amendment, ratified in 1919, prohibited the manufacture, sale, and transportation of intoxicating liquors within the United States. The Twenty-First Amendment, ratified in 1933, repealed the Eighteenth Amendment — the only instance in American constitutional history of an amendment being repealed by a subsequent amendment. Together, these amendments represent a remarkable constitutional experiment in social engineering and its reversal, providing important lessons about constitutional design, federal power, and the limits of constitutional regulation of personal behavior.

The Prohibition era demonstrated both the potential and the limitations of constitutional amendments as instruments of social reform. The movement for national Prohibition drew on decades of temperance advocacy, religious moralism, and Progressive faith in government’s power to improve society. The failure of Prohibition and its repeal illustrated the challenges of enforcing unpopular laws and the Constitution’s capacity for self-correction.

The Temperance Movement and the Drive for Prohibition

The temperance movement had deep roots in American religious and social reform. Organizations like the Women’s Christian Temperance Union and the Anti-Saloon League campaigned for decades against alcohol consumption, framing it as a moral, social, and economic evil. By the early twentieth century, many states and localities had adopted local option laws prohibiting alcohol sales.

The movement gained momentum during World War I, when anti-German sentiment targeted German-American brewers, and when grain conservation for the war effort provided additional justification for restricting alcohol production. The War-Time Prohibition Act of 1918 temporarily prohibited the sale of alcoholic beverages, laying the groundwork for permanent constitutional prohibition.

The Eighteenth Amendment (1919)

Congress proposed the Eighteenth Amendment in December 1917, and it was ratified in January 1919, with the required thirty-six states approving within thirteen months. The amendment prohibited the manufacture, sale, and transportation of intoxicating liquors within the United States and its territories, as well as their importation and exportation. Section 2 granted Congress and the states concurrent enforcement power.

The amendment did not prohibit the consumption or possession of alcohol, only its manufacture, sale, and transportation. This distinction proved significant, as individuals could legally consume alcohol that they had possessed before Prohibition took effect. The amendment also included a seven-year ratification deadline and became effective one year after ratification, providing a transition period.

The Volstead Act

Congress enacted the National Prohibition Act, commonly known as the Volstead Act, in 1919 to enforce the Eighteenth Amendment. The Act defined intoxicating liquors as beverages containing more than 0.5% alcohol by volume and prohibited their manufacture, sale, and transportation. The Act included exceptions for medicinal, sacramental, and industrial purposes, and permitted the manufacture of non-intoxicating cider and fruit juices.

The Volstead Act was enforced by the Prohibition Bureau, a federal law enforcement agency within the Treasury Department. Enforcement proved enormously challenging, as the Bureau was underfunded, understaffed, and frequently corrupt. The federal government struggled to police the nation’s borders, coastlines, and remote rural areas against bootleggers and smugglers.

The Failure of Prohibition

Prohibition failed to achieve its stated goals and produced numerous unintended consequences. Alcohol consumption declined initially but rebounded as illegal sources developed. The illegal alcohol trade was dominated by organized crime, including notorious figures like Al Capone, who built enormously profitable criminal enterprises around bootlegging.

Prohibition generated widespread disrespect for law and law enforcement, as otherwise law-abiding citizens routinely violated the prohibition on alcohol. The federal government’s enforcement efforts strained federal resources and expanded federal police power in ways that concerned civil libertarians. The loss of tax revenue from legal alcohol sales was significant, particularly as the Great Depression created new revenue needs.

Medical and scientific opinion also shifted against Prohibition. The American Medical Association and other professional organizations questioned the public health benefits, and studies documented the harms of uncontrolled illegal alcohol production, including poisonings from poorly distilled spirits.

The Twenty-First Amendment (1933)

The Twenty-First Amendment repealed the Eighteenth Amendment, returning control over alcohol regulation to the states. Ratified in 1933 after less than ten months of deliberation, the amendment was one of the fastest ratifications in American constitutional history. The amendment was ratified through state conventions rather than state legislatures — the only amendment ratified by this method — partly to circumvent the opposition of rural state legislators who still supported Prohibition.

Section 1 repeals the Eighteenth Amendment. Section 2 provides that the transportation or importation of intoxicating liquors into any state, territory, or possession for delivery or use therein in violation of state law is prohibited. This provision preserves state authority to regulate alcohol within their borders, including the authority to maintain dry jurisdictions, and has been interpreted to give states broad latitude to regulate alcohol.

The Twenty-First Amendment and State Regulation

Section 2 of the Twenty-First Amendment grants states significant — but not unlimited — authority to regulate alcohol. The Supreme Court has held that Section 2 does not immunize state alcohol regulations from other constitutional constraints, including the Commerce Clause and the Dormant Commerce Clause. In Granholm v. Heald (2005), the Court struck down state laws that discriminated against out-of-state wineries, holding that Section 2 does not authorize states to violate the Commerce Clause.

States continue to regulate alcohol through a variety of systems, including state-controlled retail monopolies, licensing systems, restrictions on hours of sale, and local option laws allowing counties and municipalities to remain dry. The minimum drinking age of twenty-one is effectively national because of federal funding conditions, though states retain the legal authority to set lower ages.

Modern Alcohol Regulation

The repeal of Prohibition did not end alcohol regulation but transferred it from the federal constitutional level to state and local law. Federal law continues to regulate alcohol production, taxation, and interstate commerce through the Alcohol and Tobacco Tax and Trade Bureau and the Food and Drug Administration. States regulate the distribution and sale of alcohol through licensing, zoning, and law enforcement.

The Prohibition experience continues to influence constitutional debates about the limits of government power to regulate personal behavior, including debates over drug policy, gambling, and other sumptuary laws. The success of the Twenty-First Amendment in reversing a failed constitutional experiment demonstrates the Constitution’s capacity for self-correction and the value of the amendment process.

Conclusion

The Eighteenth and Twenty-First Amendments represent a unique constitutional cycle of adoption and repeal. National Prohibition was a ambitious attempt to use the Constitution to regulate personal behavior for moral and social ends, but its enforcement failures, unintended consequences, and unpopularity led to its repeal. The Twenty-First Amendment restored alcohol regulation to the states, returning to the constitutional principle that such matters are best addressed at the state and local level. The Prohibition experiment and its reversal remain a cautionary tale about the limits of constitutional social engineering and a testament to the Constitution’s capacity for learning from experience.
