The 18th Amendment to the United States Constitution Explained

US Constitution
US Constitution

Summary

The Eighteenth Amendment, ratified in 1919, prohibited the manufacture, sale, and transportation of alcohol in the U.S. but allowed personal consumption. Enforced by the Volstead Act, it led to a rise in organized crime and enforcement challenges, prompting its repeal in 1933 via the 21st Amendment. The temperance movement's push for prohibition ultimately backfired due to unintended consequences like increased illegal activity.

What Is the Eighteenth Amendment?

The Eighteenth Amendment to the United States Constitution banned the processing, moving, and selling of intoxicating alcohol and was ratified on January 16, 1919. 

However, it did not prohibit people from consuming, producing for personal consumption, or being in private possession of intoxicating liquors. 

Bottles of alcohol
The 18th Amendment ushered in the era of prohibition.

Section 1 of the 18th Amendment prohibited the “manufacture, sale, or transportation of intoxicating liquors.”

Section 2 states that the United States Congress has the power to enforce the article through pertinent legislation. 

Section 3 declared that the article would only be operative after it was ratified as a constitutional amendment.

Congress subsequently passed the Volstead Act to carry out the intent of the Eighteenth Amendment. 

The Years Preceding Prohibition

Between 1913 and 1919, the nation’s laws primarily focused on establishing an income tax, Senators being elected by the people, and prohibition.

The US government relied heavily on the revenue generated from the sale of alcohol in the early 1900s.

The government relied heavily on tax revenue from the sale of alcohol. Therefore enactment of the 16th Amendment (the income tax amendment) helped eliminate the main obstacle to prohibition.

The Sixteenth Amendment made prohibition financially feasible. It was advantageous to the temperance movement as the loss of revenue argument against prohibition was now moot.

The Volstead Act

On October 28th, 1919, Congress passed the Volstead Act, also known as The National Prohibition Act, which introduced numerous limitations concerning the manufacture, sale, and transportation of alcohol. 

United States Congress
United States Congress.

It stated which alcoholic beverages were restricted and which ones were not. Alcoholic drinks that were used for purposes such as religion or in medicine were exempt. 

President Woodrow Wilson refused to sign the bill. Still, the House of Representatives and Senate overrode his veto, and the Volstead Act was enacted.

January 17th, 1920, was the date the Volstead Act would go into effect all over the country. It was the earliest date allowed for prohibition by the Eighteenth Amendment.

President Woodrow Wilson
President Woodrow Wilson vetoed the Volstead Act but his veto was overridden by Congress.

The Repeal of the Eighteenth Amendment

After the Eighteenth Amendment was ratified and enacted in 1920, it remained in effect for 13 years. However, in 1933 the Eighteenth Amendment was repealed after the ratification of the 21st Amendment.

The temperance movement had long advocated for prohibition in the United States.

This was despite the fact that there were powerful political coalitions that had initially advocated for prohibition.

Protestants, progressives, and many women, such as those in the Women’s Christian Temperance Union, had been vocal for a number of years on the negative impact alcohol was having on American society and public health.

Organized crime benefited greatly from prohibition.

What the temperance movement did not foresee, however, was how prohibition would lead to a direct rise in organized crime, exemplified by the infamous gangster Al Capone.

Enforcement of the Volstead Act became a near-impossible task, and a large and ultimately successful political movement grew calling for the repeal of the 18th Amendment.
