Britian and Argentina marked the 30th anniversary of the Falklands War on Monday, despite diplomatic tensions between the two countries.

Unfortunately, although it has been thirty years since the war, there is still a significant level of disagreement between the two countries - both claim ownership of the islands.

So what exactly happened, all those years back?

The first sighting of the Falkland Islands was made by Dutchman Seebald Dee Weerdt in 1600. The English, however, made the first recorded landing, much later in 1690. From 1690 to 1820 the island changed hands between Britain, France and Spain. In 1820, Argentina claimed the islands, only for the British to come storming back in 1833.

The UK has controlled the Falklands since then, except for a brief period in 1982, when Argentina once again attempted an invasion. The South American country landed on the South Georgia island and hoisted a flag without British consent. The action was met with a UK task force that was dispacted on 2 April, 1982, according to a Guardian report.

Argentine forces surrendered on 14 June of the same year; however, the 74-day war resulted in nearly 250 British troops and 650 Argentinean troops being killed.
