What really happened in 17th-century tulip mania?
The classic cautionary tale - Dutchmen swapping mansions for a single flower bulb, then drowning themselves in canals when the market collapsed and dragged the whole economy into depression - is largely a Victorian morality fable. When a historian actually read the surviving 1630s contracts, she could not find one person bankrupted by tulips.
