Prohibition history

The 18th Amendment.

The 18th Amendment banned the manufacture, sale and transportation of intoxicating liquors in the United States. Congress passed it on 18 December 1917, the states ratified it on 16 January 1919, and it took effect one year later, on 17 January 1920. It is the only constitutional amendment ever to be repealed.

What it says

The operative sentence is short. It prohibits “the manufacture, sale, or transportation of intoxicating liquors within, the importation thereof into, or the exportation thereof from the United States and all territory subject to the jurisdiction thereof for beverage purposes”.

Read it twice and the omissions start to matter. Possession is not there. Consumption is not there. Nor is any definition of intoxicating — the amendment leaves that to Congress, along with concurrent enforcement power for the states. Those three gaps shaped the whole of the next fourteen years.

The dates that matter

18 December 1917Congress passes the amendment and sends it to the states, with a seven-year deadline.
8 January 1918Mississippi ratifies first.
16 January 1919Nebraska becomes the thirty-sixth state to ratify. The amendment is adopted.
28 October 1919Congress passes the Volstead Act over President Wilson’s veto, defining “intoxicating” as 0.5% alcohol by volume.
17 January 1920The amendment takes effect, one year after ratification as its own text required.
5 December 1933Repealed by the 21st Amendment.

Who ratified and who refused

Forty-six of the forty-eight states ratified, most of them quickly. Connecticut and Rhode Island never did. Both were small, industrial, heavily Catholic and heavily immigrant, with brewing and distilling interests and an electorate that regarded the whole project as somebody else’s religion imposed by constitutional amendment. New Jersey held out until 1922, ratifying well after the amendment was already in force and largely as a formality.

Rhode Island went further and sued. In Rhode Island v. Palmer, decided in 1920, the Supreme Court dismissed every challenge to the amendment’s validity in a famously terse opinion that announced conclusions without reasoning — which did nothing to persuade anybody who already thought the thing had been pushed through.

The geography of that split still shows up in the drinking culture of the Northeast, and it shows up in our own data: the states that fought Prohibition hardest tend to have the densest bar scenes today.

How it passed at all

Three forces converged. The first was forty years of temperance organising, which by 1917 had already made two-thirds of the country dry under state or local law — the amendment was in large part ratifying a fact on the ground. The second was the Anti-Saloon League’s single-issue pressure politics, which could deliver or destroy a legislative seat without caring about any other question.

The third was the First World War. Grain was a war resource and brewing consumed it. More damagingly, the American brewing industry was German-American to its bones, and from 1917 that was a liability no amount of lobbying could fix. Wartime prohibition arrived first as a food-conservation measure; the constitutional version followed while the argument was still running in its favour.

Income tax mattered too, in a way that is easy to miss. Before 1913 the federal government raised a large share of its revenue from liquor excise. The 16th Amendment made a national income tax possible, and a Treasury that no longer depended on whiskey could afford to ban it.

The seven-year deadline, and why it matters

Congress attached a condition that had never been used before: the amendment would lapse unless three-quarters of the states ratified within seven years. The drys accepted it because they were confident, and the wets accepted it because it was the only concession on offer. In the event ratification took thirteen months.

That deadline became constitutional law in its own right. Dillon v. Gloss, decided in 1921, upheld Congress’s power to impose one, on the reasoning that ratification should reflect a contemporaneous consensus rather than one assembled across generations. Every amendment proposed since has carried a time limit, which is a piece of ordinary constitutional practice that exists because of Prohibition.

What it did not do

It did not make drinking illegal, and the distinction was not academic. Private stocks laid in before January 1920 stayed legal, and anyone with cellar space and warning spent 1919 filling it. Clubs bought years of inventory. The Yale Club in New York is supposed to have laid in enough to last the full fourteen years, which is a story told so often it has stopped being checked — file it as reported.

It did not fund enforcement, either. Prohibition was given to the Bureau of Internal Revenue with a few thousand agents for a continent, salaries low enough to make bribery rational, and no civil-service protection until 1927.

And it did not touch the states’ own power to go further or do less. “Concurrent” enforcement meant exactly what it sounds like, and by the late 1920s several states had quietly stopped spending money on it. New York repealed its state enforcement act in 1923.

Did it work?

Partly, and briefly, and at a price almost nobody thinks was worth paying. Per-head alcohol consumption fell sharply in the first years — the usual estimate is to around a third of its pre-war level by 1921 — before climbing back to something like two-thirds of it by the end of the decade. Deaths from cirrhosis fell. Arrests for public drunkenness fell. Those are real effects and the honest histories include them.

Against that: a federal prison system that had to be expanded to hold Volstead cases, federal courts so clogged that the plea bargain became ordinary American practice, an enforcement service in which roughly one agent in twelve was dismissed for corruption, several thousand deaths from poisoned industrial alcohol, and a criminal economy that outlived the law that created it by generations.

What gets argued about is whether the first list was caused by the ban or by the collapse of legal supply chains that were already failing — and whether, if drinking was going to fall anyway, the rest of it bought anything at all.

Sixty-six words that changed a century of drinking

It is worth sitting with how unusual the 18th Amendment is as a piece of constitutional drafting. Every other amendment either structures the government or protects a liberty against it. This one reached past both and regulated a trade — the only time the Constitution has ever been used to write a piece of ordinary commercial policy.

That is the argument that eventually killed it, and it was being made from the start by people with no interest in drinking. If a constitutional amendment can ban beer, the reasoning went, then the Constitution is just a very slow statute book, and the next thing it bans will be chosen by whoever currently has thirty-six legislatures. The Association Against the Prohibition Amendment, which did more than any other organisation to bring about repeal, recruited heavily on exactly that ground.

It is also why the 21st Amendment is written the way it is. Rather than simply deleting the 18th, it hands authority over alcohol back to the states in its own second section — a deliberate statement that this was never federal business.
