About Mania

Mania is a catalog of speculative bubbles — tulip mania, the South Sea Bubble, land rushes, dot-coms and housing — each autopsied from the first easy money to the herd at the top to the crash that wiped it out, because the pattern repeats almost unchanged across four centuries.

What you'll find here

The scale, the believers, and how it ended — stated up front, never buried
A documented timeline, a three-act account, and exactly five contributing factors
The mechanism of the delusion: what made ordinary people believe and act
Transferable lessons, and real references from historians, investigators, and named press

Mania is part of The Delusion Index — a reference network of collective delusions, told as clinical dossiers: cults, manias, panics, and failed prophecies. The real people harmed are treated with gravity, never as spectacle.

The rest of The Delusion Index

The Flock Documented groups, from the first belief to the end. Hysteria Documented panics, from the first belief to the end. Doomsday Documented prophecies, from the first belief to the end.
