Explanation: In the mid-17th century AD, the immensely prosperous Dutch Republic (the Netherlands) was exposed to a fascinating and beautiful new flower from Turkiye - the tulip! Originally a status symbol, the explosion of popularity led to tulips, and exotic varieties of the tulip, becoming a vehicle for investment and speculation. For some three years, entire fortunes were won and lost on tulip speculation, with individual bulbs being worth the same price as a good plot of land, or an ordinary artisan's house!
The tulip market collapsed as suddenly as it arose - not out of disappointment with the tulip, but a realization that the whole business of investing fortunes in ornamental flowers might've been a bit silly. Tulips are still very popular in the Netherlands to this day - but you won't be making fortunes day-trading them!
