Diego Garcia

Diego Garcia is the largest island of the Chagos Archipelago. It has been used as a joint UK–U.S. military base since the 1970s, following the expulsion of the Chagossians by the UK government. The Chagos Islands are set to become a former British overseas territory — a treaty to transfer sovereignty from the UK to Mauritius was signed on 22 May 2025, with a provision that the military base at the island would remain under British control for at least 99 years.

Located just south of the equator in the central Indian Ocean, Diego Garcia lies east of Tanzania, east-southeast of Somalia, south of the Maldives, southwest of India, west-southwest of Sumatra, northwest of Australia, and northeast of Mauritius Island. Diego Garcia is part of the Chagos-Laccadive Ridge, an underwater mountain range that includes the Lakshadweep, the Maldives, and the other 60 small islands of the Chagos Archipelago. The island observes UTC+6 year-round.

Diego Garcia was discovered by Portuguese sailors in 1512 and remained uninhabited until the French began using it as a leper colony and for coconut plantations in the late 18th century. After the Napoleonic Wars, the island was transferred to British control. It remained part of Mauritius until 1965, when it became part of the newly formed BIOT.

In 1966, Diego Garcia had a population of 924, mostly contract workers employed in coconut plantations. However, between 1968 and 1973, the Chagossian inhabitants were forcibly removed to make way for the military base. In 2019, the International Court of Justice ruled that the UK's administration of the Chagos Archipelago was illegal, a decision supported by the United Nations, though the UK has dismissed the ruling as non-binding.

Diego Garcia remains the only inhabited island of the BIOT, with its population consisting of military personnel and contractors. It is one of two critical U.S. bomber bases in the Indo-Pacific region, alongside Andersen Air Force Base in Guam. It is nicknamed the "Footprint of Freedom" by the US Navy due to its shape and strategic location in the Indian Ocean. Provided by Wikipedia
