Outer Islands of Mauritius in the context of "Agaléga"

Isle de France (Modern French: Île de France, pronounced [il də fʁɑ̃s] ) 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 raids (see Battle of Pulo Aura and Mauritius campaign of 1809–1811) continued until 1810 when the British sent a strong expedition to capture the island. The first British attempt, in August 1810, to attack Grand Port resulted in a French victory, one celebrated on the Arc de Triomphe in Paris. A subsequent and much larger attack launched in December of the same year from Rodrigues, which had been captured a year earlier, was successful. The British landed in large numbers in the north of the island and rapidly overpowered the French, who capitulated (see Invasion of Isle de France). In the Treaty of Paris (1814), the French ceded Isle de France together with its territories including Agaléga, the Cargados Carajos Shoals, the Chagos Archipelago, Rodrigues, Seychelles, and Tromelin Island to the United Kingdom. The island then reverted to its former name, 'Mauritius'.
