What If Everyone You Knew Mortgaged Their House to Buy a Tulip? (They Did. It Was 1637.)

Hi, I’m Heather. I tell my embarrassing stories so you don’t feel so alone in the world. Today, the embarrassing story belongs to a slice of 17th-century Dutch society.

In or around February 1637, a man in Haarlem, Netherlands, showed up to a routine tulip auction and just… didn’t bid.

He didn’t really have a good reason. He wasn’t carrying a manifesto or anything. He just checked out the flowers, saw the price, and for the first time in three years, did the math. So, he bounced. And since it was the 17th century and there was no Reddit to vent his feelings, the news spread the old-school way: through sheer, pants-wetting panic.

Within days, tulip bulbs that had been worth more than canal houses were worth approximately nothing. Contracts were voided. Merchants who had been rich on Tuesday were ruined by Friday. And somewhere in Holland, a very confused sailor was probably still digesting the expensive breakfast he’d made out of a rare Semper Augustus bulb he’d mistaken for an onion.

We’ll get to the sailor shortly.

First, Some Context About Why the Dutch Lost Their Minds

The Netherlands in the 1630s was doing great, actually. Embarrassingly well. They had the highest per capita income in the world. They’d pioneered the stock market, futures contracts, and limited liability companies. The Dutch East India Company was essentially running international trade with the energy of a startup that had just closed a Series A and had entirely too many judgments about disruption.

Into this extremely confident, extremely solvent society arrived the tulip.

Tulips came from the Ottoman Empire, brought over by a botanist named Carolus Clusius in 1593. He planted them in a research garden at the University of Leiden with perfectly reasonable scientific intentions. His neighbors immediately broke in and stole them to sell for money. So the Dutch tulip trade began, as many great economic disasters do, with theft and bad judgment.

For the next several decades, tulips were a status symbol for the wealthy. Exotic. Desirable. A reasonable luxury item. This is the mundane part of the story, and it didn’t last.

Where It Gets Crazy

There’s something you need to know about the tulips to understand what happened next: certain varieties were infected with a mosaic virus that caused dramatic streaks and flames of color to appear on the petals. Nobody knew it was a virus. They just knew it was beautiful and impossible to replicate predictably, which made those bulbs unusually rare.

The rarest was called the Semper Augustus. White petals with blood-red streaks. In 1623, contemporary accounts recorded only twelve of them in the entire world. One sold for 1,000 guilders. A skilled craftsman made about 300 guilders a year, which means the Semper Augustus was already worth three years of wages, and it was just getting started.

By 1637, a single Semper Augustus bulb could cost you up to 10,000 guilders. That’s thirty-three years of wages. For one flower. That you cannot eat, cannot wear, and that will bloom for approximately one week in April, before looking like any other wilted tulip.

But the Semper Augustus had something better than practical value. It had scarcity, and it had hype, and in the 1630s those two things were doing precisely what they do now.

The Tavern Stock Exchange

By 1636, tulip trading had moved out of the gardens of the wealthy and into the taverns, where ordinary people were buying and selling tulip futures, contracts for bulbs that hadn’t bloomed yet, sometimes bulbs they’d never seen, sometimes bulbs that were still in the ground. The Dutch called it windhandel. Wind trade. They were literally buying and selling air.

The mechanics were simple and extremely unwise. You’d show up at a tavern. You’d find a seller. You’d shake hands, write something down in the tavern’s record book, pay 2.5% of the price upfront as a fee called “wine money,” because of course it was, and agree to settle the rest when the bulb was delivered months later. Then that contract would get bought and sold again. And again. Some contracts changed hands ten times in a single day.

No one was looking at the actual flowers.

Chimney sweeps and servants were said to be trading tulips. Weavers reportedly mortgaged their looms. People sold their homes, furniture, and livestock. The belief was universal and fully sincere: prices could only go up. Everyone knew the wealthy from across the world would eventually pay whatever Holland asked for these flowers. Poverty would be banished. The tulip would make everyone rich.

My dearest readers, the tulip did not make everyone rich.

The Viceroy Situation

I need to stop here and tell you about one specific transaction, because it is the most 1637 thing that has ever happened.

Someone supposedly traded one Viceroy tulip bulb, which was not the most expensive variety, not the Semper Augustus. It was just a a moderately coveted Viceroy, for the following:

Two loads of wheat. Four barrels of beer. Two hogsheads of wine. Four fat oxen. Eight fat pigs. Twelve fat sheep. A bed. A suit of clothes. One thousand pounds of cheese. And a silver drinking cup.

One bulb. A single flower. Something a squirrel could destroy on any given afternoon.

The cheese alone was a thousand pounds. I want you to sit with the cheese. Someone allegedly handed over what amounted to a fully stocked farm, a furnished bedroom, a wardrobe, and enough cheese to supply a small village through winter, and in exchange received a single tulip bulb that they would not be able to plant for months because it was the wrong season.

This was considered a reasonable transaction at the time. Everyone agreed. Contracts were signed.

The Sailor

There is a story, likely embellished, possibly not, we aren’t sure because the 17th century had a complicated relationship with journalism.

It is about a visiting sailor who arrived at a wealthy merchant’s home in Amsterdam.

The merchant had, as wealthy merchants did during the peak of tulip mania, placed his prized bulbs on display indoors rather than risk planting them. The bulbs were too valuable to put in the ground. The ground was where things got eaten by things.

The sailor, unfamiliar with the cultural moment he had walked into, saw what appeared to be an onion sitting on the sideboard. He was hungry. He ate it with his herring for breakfast.

It was a Semper Augustus bulb. Worth, at the time, roughly the annual wages of an entire ship’s crew.

The sailor was imprisoned. The merchant was inconsolable. The bulb was gone.

Somewhere in this story is a lesson about the difference between perceived value and a thing you can actually eat, but I don’t want to editorialize too hard because the Dutch figured that out on their own soon enough.

February 3, 1637

A routine auction in Haarlem. Seventy tulip bulbs up for sale.

The auctioneer called the first lot. Silence. He lowered the price. More silence. He lowered it again.

Nobody bid. Not one person, at any price.

The room understood what this meant before anyone said it out loud. The auctioneer kept lowering the price; this detail is in the historical record, and it is haunting, and still nothing. The buyers had simply decided, collectively and all at once, that they didn’t want to be the person holding the bulb when the music stopped.

Word spread overnight. By the following day, every tulip market in every Dutch city had collapsed. Bulbs that had been worth fortunes on Monday were unsellable on Thursday. People who had borrowed against their homes to buy futures contracts now held paper that was worth a fraction of what they’d promised to pay. The Dutch government eventually stepped in and allowed buyers to void contracts for a fee of roughly 3.5% of the original price.

The Viceroy guy got to keep his cheese. The cheese was fine.

Where Historians Argue

Here’s where I have to be honest with you, because the full story is weirder and more interesting than the cautionary tale version.

Modern historians, particularly Anne Goldgar, have pointed out that a lot of what we know about tulip mania comes from Charles Mackay’s 1841 book Extraordinary Popular Delusions and the Madness of Crowds, which was written two hundred years after the fact, by a man who loved a dramatic narrative, using sources that were largely Calvinist moralists who wanted to illustrate the dangers of greed.

Mackay’s account of suicides, mass ruin, and total economic collapse is probably exaggerated. The actual economic fallout was largely contained to a relatively small network of traders. The Dutch Republic continued to be the wealthiest nation in the world.

The mania and the crash were real. The thousand pounds of cheese was also real. But the apocalyptic version of the story, where the whole country drowned in the canals, is mostly entertainment-based history, is how I would explain it.

What actually happened was smaller and somehow worse: ordinary people who could not afford to lose made extremely bad bets based on the assumption that the party would continue indefinitely, lost, and suffered consequences that were devastating to them personally, even if they didn’t register as a national crisis. The alleged chimney sweep who mortgaged his tools to buy a futures contract was ruined regardless of what the GDP numbers said.

Which is maybe the most relatable part of the whole thing.

Why This Story Won’t Go Away

We keep telling the tulip mania story because we keep doing the tulip mania. The asset changes, but the psychology doesn’t. The same architecture: scarcity, social proof, FOMO, the sincere belief that this time the fundamentals actually support the price, and then one quiet auction where no one bids and the whole thing evaporates in seventy-two hours.

The Dutch built the most sophisticated financial system in the world and immediately used it to inflate a flower bubble. This is not a story about stupidity, however. The people who traded tulip futures were not stupid. They were human, which is a different problem entirely and one that has proven significantly harder to fix.

The bulbs bloomed that spring. Nobody cared anymore. A tulip is, ultimately, just a flower.

The sailor had the right idea. He just had terrible timing.

If you made it this far, thank you. If you have also once made a financial decision that looked fine at the time and catastrophic in retrospect, you are in excellent company. The Dutch were running the entire world economy, and they still couldn’t resist a pretty flower. The bar is on the ground. We’re fine-ish.
