evidence: The 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.
