The sovereignty dispute, diplomacy and seventy-four-day conflict of 1982.
The Falklands War followed Argentina's invasion of the Falkland Islands on 2 April 1982. Britain sent a task force more than 8,000 miles from home while diplomacy continued through the United Nations, the United States and regional intermediaries.
The conflict lasted seventy-four days and included naval, air and land combat. It cannot be understood only as a British military success: Argentine conscripts, islanders and competing ideas of sovereignty are central to its history.
Britain and Argentina had long advanced competing claims. Diplomatic negotiations continued for years, but the Argentine junta chose invasion amid domestic crisis. The decision misjudged the likelihood and scale of a British response.
Carrier aviation, submarines, merchant shipping and improvised logistics sustained the task force. British forces landed at San Carlos and fought across East Falkland. Argentine aircraft posed a serious threat, while British nuclear submarines shaped naval movement.
Argentine forces surrendered on 14 June. The defeat weakened the junta and helped restore democracy; victory strengthened Margaret Thatcher's government. The sovereignty dispute continues, as do debates about intelligence, veteran welfare and commemoration.
The war can be studied through cabinet papers, military records, veterans' testimony, journalism and Argentine as well as British sources. Operational accounts need to be read alongside diplomacy and the longer sovereignty dispute.
Historians distinguish the causes of the 1982 invasion from the political consequences of British victory. Memory in the islands, Argentina and the United Kingdom remains different and politically active.
