The Ellice Islands were administered as British protectorate by a Resident Commissioner from 1892 to 1916 as part of the British Western Pacific Territories (BWPT), and later as part of the Gilbert and Ellice Islands colony from 1916 to 1974.
A referendum was held in December 1974 to determine whether the Gilbert Islands and Ellice Islands should each have their own administration. As a consequence of the referendum, the Gilbert and Ellice Islands colony ceased to exist on 1 January 1976 and the separate British colonies of Kiribati and Tuvalu came into existence. Tuvalu became fully independent within the Commonwealth on 1 October 1978. On 17 September 2000 Tuvalu became the 189th member of the United Nations.
