The Mississippi Company was a corporation holding a business monopoly in French colonies in North America and the West Indies. When land development and speculation in the region became frenzied and detached from economic reality, the Mississippi bubble became one of the earliest examples of an economic bubble.

In 1718, there were only 700 Europeans in Louisiana. The Mississippi Company arranged ships to move 800 more, who landed in Louisiana in 1718, doubling the European population. John Law encouraged Germans, particularly Germans of the Alsatian region who had recently fallen under French rule, and the Swiss to emigrate. They give their name to the regions of the Côte des Allemands and the Lac des Allemands in Louisiana.

Prisoners were set free in Paris in September 1719 onwards, under the condition that they marry prostitutes and go with them to Louisiana. The newly married couples were chained together and taken to the port of embarkation. In May 1720, after complaints from the Mississippi Company and the concessioners about this class of French immigrants, the French government prohibited such deportations. However, there was a third shipment of prisoners in 1721.
