An 18th-century speculative bubble resulting from the Mississippi Company, which had a charter from the King of France for overseas trade with the Louisiana Territory and elsewhere. The Company's founder, John Law, promoted the trade of the stock, which was guaranteed indirectly by the King. The company issued notes (through the Banque Royale) until the government admitted it did not have sufficient coinage to cover the notes it had printed. This resulted in a bank run and the burst of the bubble in 1720. The Mississippi bubble was one of the first times a bank issued paper money.
