Chagos Archipelago
The Chagos Archipelago was formerly administered from Mauritius. Then, a few years before independence in 1968, the British annexed the island under the British Indian Ocean Territory and leased the main island, Diego Garcia, to the USA as a military base for its Rapid Deployment Force. The Chagos islanders were moved to Mauritius and given financial compensation for the upheaval.
After the departure of the Dutch 1n 1710, Guillaume Dufresne D'Arsel, while on the route to India, landed in Mauritius in September 1715 and claimed the island for France. He named Mauritius 'Ile de France'. However it was only in 1721 that the French started their occupation of the island.
