Originally colonised by the French, Diego Garcia was ceded, along with the rest of the Chagos Archipelago, to the United Kingdom in the Treaty of Paris (1814) at the conclusion of a portion of the Napoleonic Wars. Diego Garcia and the Chagos Archipelago were administered by the colonial government on the island of Mauritius until 1965, when the UK purchased them from the self-governing colony of Mauritius for £3 million, and declared them to be a separate British Overseas Territory. The BIOT administration was moved to Seychelles following the independence of Mauritius in 1968 until the independence of Seychelles in 1976, and to a desk in the Foreign and Commonwealth Office in London since.
