Chilean Antarctic Territory
The island was first claimed for Britain on 16 October 1819, formally annexed by Britain as part of the Falkland Islands Dependencies in 1908, and now as part of the separate British Antarctic Territory. The Island was claimed by Chile in 1940, as part of the Chilean Antarctic Territory. It was also claimed by Argentina in 1943, now as part of Argentine Antarctica, called by the Argentines "Isla Veinticinco de Mayo" (25 May) in honour of their National day. The US and Russia do not recognize these claims and have formally reserved their right to claim Antarctic territories.
