The Mississippi Company of 1684 became the Company of the West in 1717, and expanded as the Company of the Indies from 1719. This corporation, which held a business monopoly in French colonies in North America and the West Indies, became one of the earliest examples of an economic bubble.
The Banque Royale
In May 1716, the Banque Générale Privée ("General Private Bank"), which developed the use of paper money, was set up by convicted murderer and millionaire gambler John Law.  It was a private bank, but three quarters of the capital consisted of government bills and government-accepted notes. In August 1717, he bought the Mississippi Company to help the French colony in Louisiana. In the same year Law conceived a joint-stock trading company called the Compagnie d'Occident (The Mississippi Company, or, literally, "Company of [the] West"). Law was named the Chief Director of this new company, which was granted a trade monopoly of the West Indies and North America by the French government.
The bank became the Banque Royale (Royal Bank) in 1718, meaning the notes were guaranteed by the king, Louis XV of France. The company absorbed the Compagnie des Indes Orientales ("Company of the East Indies"), the Compagnie de Chine ("Company of China"), and other rival trading companies and became the Compagnie Perpetuelle des Indes on 23 May 1719 with a monopoly of commerce on all the seas. Simultaneously, the bank began issuing more notes than it could represent in coinage; this led to an economic inflation, which was eventually followed by a bank run when the value of the new paper currency was halved.
The Mississippi Bubble
Law exaggerated the wealth of Louisiana with an effective marketing scheme, which led to wild speculation on the shares of the company in 1719. The scheme promised success for the Mississippi Company by combining investor fervor and the wealth of its Louisiana prospects into a sustainable, joint-stock, trading company. The popularity of company shares were such that they sparked a need for more paper bank notes, and when shares generated profits the investors were paid out in paper bank notes. In 1720, the bank and company were merged and Law was appointed by Philippe II, Duke of Orleans, then Regent for Louis XV, to be Comptroller General of Finances to attract capital. Law's pioneering note-issuing bank thrived until the French government was forced to admit that the number of paper notes being issued by the Banque Royale exceeded the value of the amount of metal coinage it held.
The "bubble" burst at the end of 1720, when opponents of the financier attempted to convert their notes into specie en masse, forcing the bank to stop payment on its paper notes. By the end of 1720 Philippe d'Orléans had dismissed Law from his positions. Law then fled France for Venice, where he lived off his gambling. He was buried in the church San Moisè in Venice.

Law devalued shares in the company in several stages during 1720, and the value of bank notes was reduced to 50 percent of their face value. By September 1720 the price of shares in the company had fallen to 2,000 livres and to 1,000 by December. The fall in the price of stock allowed Law's enemies to take control of the company by confiscating the shares of investors who could not prove they had actually paid for their shares with real assets rather than credit. This reduced investor shares, or shares outstanding, by two-thirds. By September 1721 share prices had dropped to 500 livres, where they had been at the beginning.
