Was Tulip Mania Real? The Bubble Story That Grew in the Retelling
The short version: tulip prices in the Dutch Republic did rise sharply and then collapse in early February 1637; one auction in Alkmaar on 5 February raised about 90,000 guilders for a collection of bulbs. But the dramatic version most people know comes largely from Charles Mackay's 1841 book, which retold moralising pamphlets from 1637 without sources. The historian Anne Goldgar, working through archives in Haarlem, Amsterdam, Alkmaar and Enkhuizen, identified about 350 people in the trade and found no bankruptcy she could attribute to tulips, and no sign of wider economic damage. A real price bubble, a mostly invented catastrophe.
Cousin Kevin announced at the Red Lion that he was buying a new crypto coin, because it had gone up 400% in a week and was "basically guaranteed". Uncle Gary put down his pint with the gravity of a man about to quote history.
"Tulips," he said. "Holland, 1600s. People paid a house for one bulb. Then it crashed, everybody was ruined, merchants threw themselves into the canals. A sailor ate a bulb thinking it was an onion, and they put him in prison for it." Old Ted, who grows tulips on his allotment, said he'd had bulbs eaten by squirrels and nobody had prosecuted the squirrels. Kevin asked how Gary knew all this. Gary said everybody knows it.
What really happened
Part of the story is true. In the 1630s, rare tulips, especially the striped "broken" varieties, became a luxury collectors' item in the Dutch Republic. Prices rose fast through the winter of 1636 to 1637, with people trading contracts for bulbs that were still in the ground.
- On 5 February 1637, an auction in Alkmaar sold the bulbs of a dead innkeeper, Wouter Winkel, for the benefit of his orphaned children. It raised about 90,000 guilders, at a time when a skilled craftsman earned a few hundred a year.
- Within days, prices collapsed. Buyers refused to pay for contracts signed at the peak.
- The disputes dragged on. The city of Haarlem eventually allowed buyers to cancel contracts for a small fraction of the agreed price.
So yes: prices rose wildly and crashed. That part is in the records.
Where the rest came from
The version Gary knows, with the ruined merchants, the canals and the sailor, comes mainly from one source: Charles Mackay's Extraordinary Popular Delusions and the Madness of Crowds, published in 1841, more than 200 years later. Mackay drew on pamphlets printed in 1637, which were moral tales warning against greed, not reports. He gave no references for his most colourful stories. Later writers quoted Mackay, and later still writers quoted them.
In 2007, the historian Anne Goldgar published the results of years in the archives of Haarlem, Amsterdam, Alkmaar and Enkhuizen: notaries' records, court cases, wills.
- She identified about 350 people involved in the trade, mostly well-off merchants and craftsmen.
- She found no bankruptcy she could attribute to tulips.
- She found no sign that the crash damaged the wider Dutch economy, which was booming before and after.
Not finding a ruined tulip trader isn't proof that none existed: records are incomplete. But a mania that ruined a nation should have left a mark in the court papers of the cities where it happened, and it didn't.
Why the dramatic version survived
Stories compete to be retold, and the vivid ones win. A sailor eating a fortune is more fun to repeat than "about 350 well-off people had a contract dispute". Each retelling drops the dull details and keeps the drama. This is survivorship bias applied to anecdotes: we hear the stories that survived retelling, and mistake them for a sample of what happened. Choosing the most striking examples to prove a point is cherry-picking, and when a moralising pamphlet does it, then a famous book quotes the pamphlet, the cherries start to look like the whole orchard.
How to check a famous story
1. Follow the citations back. If ten books cite each other and the trail ends in one unsourced anecdote, you have one source, not ten.
2. Ask how old the source is. A book written 200 years after the event, based on sermons, is not a witness.
3. Look for the dull records. Courts, contracts, accounts. Catastrophes leave paperwork.
Where it costs you money
The lesson for Kevin isn't "bubbles are myths". Prices of things with no income, valued only by what the next buyer will pay, really can rise wildly and then collapse, and tulip prices did. The lesson is to judge an investment by checkable facts (what it produces, what it costs, what the next buyer is relying on) rather than by a frightening story or an exciting one. A coin that rose 400% in a week has told you about its last week, and nothing about its next one.
The moral
Kevin didn't buy the coin, mainly because the app asked for his passport and he couldn't find it. The coin fell 80% the following week. Gary called this "exactly like the tulips", and Kevin pointed out that, according to the archives, nobody he could find was ruined by the tulips either. Old Ted has started selling bulbs from his allotment to the regulars. They are, he says, an ancient and famous investment, and he will accept payment in cider. The squirrels remain at large.
The pub conversation and the coin are fictional. Historical details are from Anne Goldgar's Tulipmania (2007) and standard accounts of the 1637 Alkmaar sale; figures for the auction vary slightly between sources. Nothing here is a view on any crypto asset. Educational content, not financial advice.
