The Falklands War was a conflict between Argentina and the United Kingdom in 1982 over the disputed Falkland Islands. The war began when Argentina invaded the islands, leading to a swift military response from the UK, which sought to reclaim its territory. The conflict lasted for about ten weeks, resulting in significant casualties on both sides. Ultimately, British forces regained control of the islands, and the war had lasting effects on both nations, shaping their political landscapes and national identities.
