Isle de France (Île de France in modern French) was the name of the Indian Ocean island which is known as Mauritius and its dependent territories between 1715 and 1810, when the area was under the French East India Company and part of France's empire. Under the French, the island witnessed major changes. The increasing importance of agriculture led to the importation of slaves and the undertaking of vast infrastructural works that transformed Port Louis into a major capital, port, warehousing, and commercial centre.
