Background: Discovered in the 16th century and settled in the mid-18th century, the islands have since been the subject of a territorial dispute, first between Britain and Spain, then between Britain and Argentina. The UK asserted its claim to the islands by establishing a naval garrison there in 1833. Argentina invaded the islands on 2 April 1982. The British responded with an expeditionary force that landed seven weeks later and after fierce fighting forced Argentine surrender on 14 June 1982.
