Tulip Mania: the classic story of a Dutch financial bubble is mostly wrong: https://theconversation.com/tulip-mania-the-classic-story-of...

While the story itself might be inflated, it still shows that a bubble doesn't have to be at the start of the market.

And the South Sea company collapse far beyond its founding _definitely_ had ramifications.

I don't know if you read that link or have read elsewhere on the topic but modern economists argue the tulip mania thing wasn't even a bubble and if it was, it was far smaller than you probably assume. Even the wikipedia page covers these topics quite nicely.

According to https://en.wikipedia.org/wiki/Tulip_mania it was more like 3 years:

"contract prices for some bulbs of the recently introduced and fashionable tulip reached extraordinarily high levels, with the major acceleration starting in 1634 and then dramatically collapsing in February 1637"

From the same page -- the Tulip market didn't start at the time of the bubble.

   Their popularity and cultivation in the United Provinces (now the Netherlands)[32] is generally thought to have 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

the tulip bubble lasted like 8 months
