The Falklands War was a ten-week undeclared war between Argentina and the United Kingdom.

The conflict was over two British dependent territories in the South Atlantic: the Falkland Islands and South Georgia.

The war began in April 1982 when Argentina, led by a military junta, invaded and occupied the Falkland Islands.

The Argentine junta launched the invasion primarily to distract from domestic economic problems and to rally nationalist support.

The British government, led by Prime Minister Margaret Thatcher, responded by dispatching a naval task force to retake the islands.

The conflict involved naval warfare, air battles, and amphibious landings.

Key events included the controversial sinking of the Argentine cruiser General Belgrano by a British submarine and the sinking of the British destroyer HMS Sheffield by an Exocet missile.

After a series of land battles, the Argentine forces on the islands surrendered in June 1982.

The war resulted in a British victory.

The outcome led to a surge of patriotic support for Thatcher in Britain and the downfall of the military junta in Argentina, paving the way for the restoration of democracy there.
