What name is given to the 1637 collapse of Dutch tulip-bulb prices?

The 1637 collapse of Dutch tulip-bulb prices is known as tulip mania.

Tulips became fashionable in the Dutch Republic during the seventeenth century, and rare varieties attracted intense interest. Contracts for bulbs were traded, sometimes before the bulbs were delivered, and prices for certain varieties rose dramatically.

In February 1637, buyers stopped accepting ever-higher prices at a Haarlem auction. Prices then fell rapidly, leaving some traders unable or unwilling to complete contracts. The episode became a classic example of speculative bubbles.

Modern historians caution that later popular accounts exaggerated the scale of the mania and its damage to the Dutch economy. It was not necessarily a nationwide economic catastrophe, and many famous claims about universal ruin are unsupported. Nevertheless, the event remains an influential case study in crowd behavior, leverage, expectations, and asset-price reversals.
