Tulip mania

Tulip mania (Dutch: tulpenmanie) was a period during the Dutch Golden Age when contract prices for some bulbs of the recently introduced and fashionable tulip reached extraordinarily high levels. The major acceleration started in 1634 and then dramatically collapsed in February 1637. It is generally considered to have been the first recorded speculative bubble or asset bubble in history. In many ways, the tulip mania was more of a then-unknown socio-economic phenomenon than a significant economic crisis. It had no critical influence on the prosperity of the Dutch Republic, which was one of the world's leading economic and financial powers in the 17th century, with the highest per capita income in the world from about 1600 to about 1720. The term tulip mania is now often used metaphorically to refer to any large economic bubble when asset prices deviate from intrinsic values.

Forward markets appeared in the Dutch Republic during the 17th century. Among the most notable was one centred on the tulip market. At the peak of tulip mania, in February 1637, certain tulip bulbs sold for more than 10 times the annual income of a skilled artisan. Research is difficult because of the limited economic data from the 1630s, much of which comes from biased and speculative sources. Some modern economists have proposed rational explanations, rather than a speculative mania, for the rise and fall in prices. For example, other flowers, such as the hyacinth, also had high initial prices at the time of their introduction, which then fell as the plants were propagated. The high prices may also have been driven by expectations of a parliamentary decree that contracts could be voided for a small cost, thus lowering the risk to buyers.

The 1637 event gained attention in 1841 with the publication of the book Extraordinary Popular Delusions and the Madness of Crowds, written by Scottish journalist Charles Mackay, who wrote that at one point 5 hectares (12 acres) of land were offered for a Semper Augustus bulb. Mackay claimed that many investors were ruined by the fall in prices, and Dutch commerce suffered a severe shock. Although Mackay's book is often referenced, his account is contested. Many modern scholars believe that the mania was not as destructive as he described.

The introduction of the tulip to Europe is often attributed to Ogier de Busbecq, the ambassador of Charles V, Holy Roman Emperor, to Sultan Suleiman the Magnificent, who sent the first tulip bulbs and seeds to Vienna in 1554 from the Ottoman Empire. Tulip bulbs, along with other new plant life like potatoes, peppers, tomatoes, and other vegetables, came to Europe in the 16th century. These bulbs were soon distributed from Vienna to Augsburg, Antwerp, and Amsterdam.

Their popularity and cultivation in the United Provinces (now the Netherlands) started in earnest around 1593 after the Southern Netherlandish botanist Carolus Clusius had taken up a post at the University of Leiden and established the hortus academicus. He planted his collection of tulip bulbs and found that they were able to tolerate the harsher conditions of the Low Countries. Shortly thereafter, the tulip grew in popularity.

The tulip was different from other flowers known to Europe at that time, because of its intense saturated petal colour. The appearance of the nonpareil tulip as a status symbol coincides with the rise of newly independent Holland's trade fortunes. No longer the Spanish Netherlands, its economic resources could now be channelled into commerce and Holland embarked on its Golden Age. Amsterdam merchants were at the centre of the lucrative East Indies trade, where one voyage could yield profits of 400%.

As a result, tulips rapidly became a coveted luxury item, and a profusion of varieties followed. They were classified in groups: the single-hued tulips of red, yellow, or white were known as Couleren; the multicolored Rosen (white streaks on a red or pink background); Violetten (white streaks on a purple or lilac background); and the rarest of all, the Bizarden ('Bizarres') (yellow or white streaks on a red, brown, or purple background). The multicolour effects of intricate lines and flame-like streaks on the petals were vivid and spectacular, making the bulbs that produced these even more exotic-looking plants highly sought after. It is now known that this effect is due to the bulbs being infected with a type of tulip-specific mosaic virus, known as the "tulip breaking virus", so called because it "breaks" the one petal colour into two or more. Less conspicuously, the virus also progressively impairs the tulip's production of daughter bulbs. The historian Philipp Blom theorised in his book, Nature's mutiny, that the mania might also have been driven by the effects of the Little Ice Age, which left most other flowers dry and shrivelled by the temperature, while the tulip was the one which sustained itself.

Growers named their new varieties with exalted titles. Many early forms were prefixed Admirael ('admiral'), often combined with the growers' names: Admirael van der Eijck was perhaps the most highly regarded of about fifty so named. Generael ('general') was another prefix used for around thirty varieties. Later varieties were given even more extravagant names, derived from Alexander the Great or Scipio, or even "Admiral of Admirals" and "General of Generals". Naming could be haphazard and varieties highly variable in quality. Most of these varieties have now died out.
