Understand the sovereignty dispute, diplomacy and military campaign of the 1982 Falklands War.
Start here
Overview
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.

The essential guide
01
The sovereignty dispute
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.
02
A distant campaign
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.
03
Consequences and memory
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.
04
Evidence, memory and disputed sovereignty
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.
05
Key developments and why they matter
2 April 1982 marks argentine invasion. Argentine forces occupied the Falkland Islands. 25 April marks south georgia retaken. British forces accepted the Argentine surrender on South Georgia. These dates matter because each development grew from earlier events and changed what people could do next.
2 May marks general belgrano sunk. HMS Conqueror sank the Argentine cruiser. 21 May marks san carlos landings. British ground forces began the campaign on East Falkland. Reading these events together connects political decisions with changes in war, work and everyday life.
14 June marks surrender at port stanley. Organised fighting ended on the islands. Together, these later events show how Falklands War developed over time and why its consequences lasted.
06
How historians explain this topic
A timeline shows what happened, but it does not explain every cause. To understand Falklands War, historians compare political decisions, available resources, ideas and the experiences of people in different places.
Important questions include why did deterrence fail before the invasion; how did distance shape every british military decision; how have national memories differed since 1982. Answering them requires evidence, not just a list of dates or the actions of one famous person.
No single source tells the whole story. Official papers, objects, personal accounts and later research answer different questions and each has limits.
