Which 1720 French company was central to the Mississippi Bubble stock-market collapse?

The Mississippi Company was central to the Mississippi Bubble, a dramatic French financial collapse in 1720. John Law reorganized the company and promoted shares connected with the development and trade of France’s North American Mississippi territory.

Speculation drove the share price far beyond what the company’s underlying business could support. Investors were attracted by ambitious claims, easy credit, and the broader financial system Law built around the Banque Générale and paper money. When confidence weakened, holders rushed to sell, and the share price collapsed.

The episode is often discussed alongside England’s South Sea Bubble, which unfolded at roughly the same time but involved a different company and national system. The Mississippi Company’s activities were tied to French colonial claims, especially Louisiana. The bubble demonstrated how monetary expansion, persuasive promotion, and expectations of easy wealth could combine into a destructive financial mania.
