What was the name of the 1720 French speculative bubble whose collapse accompanied the South Sea Bubble?

The 1720 French speculative bubble whose collapse accompanied the South Sea Bubble was the Mississippi Bubble.

The Mississippi Bubble centered on the Mississippi Company, which was reorganized under the direction of Scottish financier John Law. The company received trading privileges in French territories in North America and became closely connected with the French government’s finances.

Investors pushed the company’s shares to extraordinary levels during 1719 and 1720. Many buyers believed its American colonial prospects were far greater than the company’s real commercial performance justified. When confidence weakened, shareholders rushed to sell.

The bubble burst in 1720, causing severe losses and damaging trust in paper money and financial institutions. The episode occurred in the same year as Britain’s South Sea Bubble, but the two were separate schemes in different countries. John Law fled France after the collapse.
