The Chagos Archipelago is a group of seven atolls consisting of more than sixty islands of which Diego Garcia is the largest and the only one inhabited. Originally they were part of Mauritius but were claimed by French settlers in the 18th century and handed over to the British in 1810. Mauritius was by then also a British colony, just before it became independent from the United Kingdom in 1968, the archipelago was split and became part of the British Indian Ocean Territory. The indigenous population was evicted and a joint military base was built together with the United States on the main island. Ever since Mauritius has repeatedly addressed that the Archipelago is part of its territory and that the UK claim is a violation of United Nations resolutions banning the dismemberment of colonial territories before independence.
