The Falklands War was a war between the United Kingdom and Argentina, from Friday 2, April 1982 to June 14, 1982. It started because Argentina and the United Kingdom disagreed over who owned the Falkland Isalnds, South Georgia, and the South Sandwich Islands, all in the Atlantic Ocean, miles east of Argentina.
The war started when the military of Argentina took control of the Falkland Islands and South Georgia. This victory was short lived, as the United Kingdom sent out its navy to battle Argentina's navy and Air force, and retake the islands.
649 Argentines, 255 British, and 3 Civilians died. Argentina says that the Falkland Islands were theirs since the 19th Century and continues their belief to this day.
Argentina claimed that their invasion was simply retaking their own territory. The United Kingdom said it was an invasion of a British Territory. However, nobody officially declared war.
The war affected Argentina greatly. Patriotic feeling was everywhere in Argentina, but the loss created large protests, and quickened the overthrow of the military regime. In the United Kingdom, the Conservatives benefited from the successful outcome. Relations between the 2 nations became normalized after a meeting in Madrid in 1989, where they both released a statement that didn't affect the sovereignty of the islands.
