The British Indian Ocean Territory (BIOT) - website"HistoryThe islands of the Chagos Archipelago were uninhabited until the late 18th century, when the French established copra plantations using slave labour in 1793. The islands have been British territory since 1814 when they were ceded to Britain with Mauritius (which then included the Seychelles). For administrative convenience, and following the French practice, the islands were administered from Mauritius. As for the population of the islands, after emancipation some slaves became contract employees; the population changing over time by import of contract labour from Mauritius and, in the 1950s, from Seychelles, so that by the late 1960s, those living on the islands were contract employees of the copra plantations. Neither they, nor those permitted by the plantation owners to remain, owned land or houses. They had licences to reside there at the discretion of the owners and moved from island to island as work required.The islands were constituted as the British Indian Ocean Territory in 1965 by an Order in Council under the Royal Prerogative. This comprises all the islands of the Chagos Archipelago and until June 1976 also included the islands of Aldabra, Desroches and Farquhar which were then ceded to the Seychelles, of which they are now part. The Order in Council also provided for the appointment of a Commissioner for the Territory. One function conferred on the Commissioner was the power to make laws for the “peace, order and good government” of the Territory.The UK paid the colony of Mauritius a £3 million grant in recognition of the detachment of the Chagos Archipelago and amongst other legally binding undertakings, gave a commitment, repeated by successive governments, to cede the islands to Mauritius when no longer required for defence purposes. Similarly, the UK also paid for the construction of an airport in Seychelles in recognition of the detachment of their islands, though these were ceded after Seychelles’ independence.In a published Exchange of Notes with the US Government in 1966, the Territory was made available to meet the defence needs of the United Kingdom and the United States governments. The Exchange of Notes envisaged US use of Diego Garcia for an initial period of 50 years and could remain in force for a further 20 years beyond 2016 unless either side gives notice to terminate it in the two years before its expiry – that is, from December 2014 to December 2016. There were updates to these Notes in 1972 and 1976."

In 2019, the International Court of Justice issued an advisory opinion stating that the United Kingdom did not have sovereignty over the Chagos Islands and that the administration of the archipelago should be handed over "as rapidly as possible" to Mauritius. Since this, the United Nations General Assembly and the International Tribunal for the Law of the Sea have reached similar decisions.In October 2024, the UK agreed to hand over the Chagos Islands to Mauritius and stated that Mauritius "will now be free to implement a programme of resettlement on the islands of the Chagos Archipelago, other than Diego Garcia". The UK will also set up a trust fund for the scattered Chagossian diaspora, now numbering 10,000."
