There is actually an interesting part in Dutch history that was almost forgotten until about 6 years ago all the Internet stocks and investments collapsed: The Tulip Mania:
The term tulip mania (alternatively tulipomania) is used metaphorically to refer to any large economic bubble. The term originally came from the period in the history of the Netherlands during which demand for tulip bulbs reached such a peak that enormous prices were charged for a single bulb. It took place in the first part of the 17th century, especially in 1636–37.
The event is remembered in part because of its extended discussion in the book Extraordinary Popular Delusions and the Madness of Crowds, written by popular British journalist Charles Mackay in 1843, more than two centuries after the event.
