Background | Established as a territory of the UK in 1965, a number of the British Indian Ocean Territory (BIOT) islands were transferred to the Seychelles when it attained independence in 1976. Subsequently, BIOT has consisted only of the six main island groups comprising the Chagos Archipelago. The largest and most southerly of the islands, Diego Garcia, contains a joint UK-US naval support facility. All of the remaining islands are uninhabited. Former agricultural workers, earlier residents in the islands, were relocated primarily to Mauritius but also to the Seychelles, between 1967 and 1973. In 2000, a British High Court ruling invalidated the local immigration order which had excluded them from the archipelago, but upheld the special military status of Diego Garcia. | The Iles Eparses, or scattered islands, are a group of five French entities - Bassas da India, Europa Island, Glorioso Islands, Juan de Nova Island, and Tromelin Island - which on 1 April 1960 came under the authority of the Minister in charge of overseas possessions. On 19 September 1960 by decree, the islands were transferred to the charge of the Prefet of Reunion where they remained until 3 January 2005 when they were transferred by another decree to the Senior Administrator of the Territory of the French Southern and Antarctic Lands (TAAF).
Bassas da India: A French possession since 1897, this atoll is a volcanic seamount surrounded by reefs and awash at high tide. Europa Island: A French possession since 1897, the island is heavily wooded; it is the site of a small military garrison that staffs a weather station. Glorioso Islands: A French possession since 1892, the Glorioso Islands are composed of two lushly vegetated coral islands (Ile Glorieuse and Ile du Lys) and three rock islets. A military garrison operates a weather and radio station on Ile Glorieuse. Juan de Nova Island: Named after a famous 15th century Spanish navigator and explorer, the island has been a French possession since 1897. It has been exploited for its guano and phosphate. Presently a small military garrison oversees a meteorological station. Tromelin Island: First explored by the French in 1776, the island came under the jurisdiction of Reunion in 1814. At present, it serves as a sea turtle sanctuary and is the site of an important meteorological station. |
