Background | The Kingdom of Hawaii claimed the atoll in 1862, and the US included it among the Hawaiian Islands when it annexed the archipelago in 1898. The Hawaii Statehood Act of 1959 did not include Palmyra Atoll, which is now privately owned by the Nature Conservancy. This organization is managing the atoll as a nature preserve. The lagoons and surrounding waters within the 12 nautical mile US territorial seas were transferred to the US Fish and Wildlife Service and were designated a National Wildlife Refuge in January 2001. | 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 that had excluded them from the archipelago, but upheld the special military status of Diego Garcia. |

Disputes - international | none | Mauritius and Seychelles claim the Chagos Archipelago including Diego Garcia; in 2001, the former inhabitants of the Chagos Archipelago, evicted in 1967 and 1973 and now residing chiefly in Mauritius, were granted UK citizenship and the right to repatriation; in May 2006, the High Court of London reversed U.K. Government's 2004 orders of council that banned habitation on the islands; a small group of Chagossians visited Diego Garcia in April 2006; repatriation is complicated by the exclusive US military lease of Diego Garcia that restricts access to the largest viable island in the chain |
Economy - overview | no economic activity | All economic activity is concentrated on the largest island of Diego Garcia, where a joint UK-US military facility is located. Construction projects and various services needed to support the military installation are performed by military and contract employees from the UK, Mauritius, the Philippines, and the US. There are no industrial or agricultural activities on the islands. When the native Ilois return, they plan to reestablish sugarcane production and fishing. The territory makes money by selling fishing licenses and postage stamps. |
