Isle de France (, ) was a French colony in the Indian Ocean from 1715 to 1810, comprising the island now known as Mauritius and its dependent territories. It was governed by the French East India Company and formed part of the French colonial empire. Under the French, the island witnessed major changes. The increasing importance of agriculture led to the "import" of slaves and the undertaking of vast infrastructural works that transformed the capital Port Louis into a major port, warehousing, and commercial centre.
During the Napoleonic Wars, Isle de France became a base from which the French navy, including squadrons under Rear Admiral Linois or Commodore Jacques Hamelin, and corsairs such as Robert Surcouf, organised raids on British merchant ships. The island then reverted to its former name, 'Mauritius'.
History
After the Dutch had abandoned Mauritius, the island became a French colony in September 1715 when Guillaume Dufresne d'Arsel landed and took possession of it, naming the island Isle de France. The French government turned over the administration of Mauritius to the French East India Company, but the island remained free of Europeans until 1721. Furthermore, until 1735, Isle de France was administered from Île Bourbon, now known as Réunion.
By 1726, the company had made land grants to colonists, soldiers and workers. The grants' covenants specified that recipients of the grants who could not cultivate their land for a period of 3 years would lose them. Each colonist was given 20 slaves and in return had to pay yearly one tenth of their production to the French East India Company. The attempt to develop agriculture resulted in an increasing demand for labour.
