Passage: In the first half of the 20th century, the Falklands served an important role in Britain's territorial claims to subantarctic islands and a section of Antarctica. The Falklands governed these territories as the Falkland Islands Dependencies starting in 1908, and retained them until their dissolution in 1985. The Falklands also played a minor role in the two world wars as a military base aiding control of the South Atlantic. In the First World War Battle of the Falkland Islands in December 1914, a Royal Navy fleet defeated an Imperial German squadron. In the Second World War, following the December 1939 Battle of the River Plate, the battle-damaged HMS Exeter steamed to the Falklands for repairs. In 1942, a battalion en route to India was redeployed to the Falklands as a garrison amid fears of a Japanese seizure of the archipelago. After the war ended, the Falklands economy was affected by declining wool prices and the political uncertainty resulting from the revived sovereignty dispute between the United Kingdom and Argentina.Simmering tensions between the UK and Argentina increased during the second half of the century, when Argentine President Juan Perón asserted sovereignty over the archipelago. The sovereignty dispute intensified during the 1960s, shortly after the United Nations passed a resolution on decolonisation which Argentina interpreted as favourable to its position. In 1965, the UN General Assembly passed Resolution 2065, calling for both states to conduct bilateral negotiations to reach a peaceful settlement of the dispute. From 1966 until 1968, the UK confidentially discussed with Argentina the transfer of the Falklands, assuming its judgement would be accepted by the islanders. An agreement on trade ties between the archipelago and the mainland was reached in 1971 and, consequently, Argentina built a temporary airfield at Stanley in 1972. Nonetheless, Falklander dissent, as expressed by their strong lobby in the UK Parliament, and tensions between the UK and Argentina effectively limited...
