‘Response to crises: Korean War, Suez, the Falklands War, First Gulf War; decolonisation and changing attitudes to the Commonwealth.’
Britain’s post-war international role was challenged by crises, global realignments, and the decline of Empire. This subtopic explores how governments managed crises and decolonisation.
Post-War Crises and International Position
The Korean War (1950–1953)
Britain entered the Korean War as part of a United Nations coalition after North Korea invaded the South. British involvement was significant though secondary to US leadership.
Britain sent ground, naval, and air forces.
It underlined Britain’s commitment to collective security through the UN.
Showed Britain’s dependence on the USA for global influence.
Reinforced Britain’s claim to be a world power despite imperial decline.
Collective Security: A system where states act together, usually through an international body like the UN, to respond to threats and aggression.
The Korean conflict emphasised Britain’s willingness to act militarily but exposed limits of its resources compared to superpowers.
The Suez Crisis (1956)
The Suez Crisis marked a turning point in Britain’s world status. Egyptian President Gamal Abdel Nasser nationalised the Suez Canal, threatening Western oil supplies.
Britain, alongside France and Israel, launched a military intervention.
The USA refused to support the operation, fearing escalation during the Cold War.
International condemnation, economic pressure, and lack of US backing forced a humiliating withdrawal.
Consequences:
Britain’s diminished role as a global power was exposed.
It reinforced dependency on the USA in international crises.
Damaged Britain’s prestige, especially in the Commonwealth and the wider world.
The Falklands War (1982)
The Falklands War was a brief but decisive conflict that temporarily revived Britain’s reputation for global reach.
Argentina invaded the Falkland Islands in April 1982.

The war confirmed that Britain’s world role depended on multilateral action with the US and international organisations.
Decolonisation and the Commonwealth
The Process of Decolonisation
After 1945, Britain faced increasing demands for independence across its empire. Economic weakness and rising nationalist movements hastened decolonisation.
Key stages:
India achieved independence in 1947, inspiring other colonies.
African independence movements accelerated during the 1950s and 1960s.
By the 1970s, most colonies had become independent states.
Decolonisation was shaped by:
Pressure from the USA and international opinion, especially the UN.
The impracticality of maintaining imperial control.
Britain’s economic difficulties and desire to reduce overseas commitments.
The Commonwealth
The Commonwealth of Nations became the framework for Britain’s post-imperial relationships.
Brought together independent states, many formerly under British rule.
Promoted political, economic, and cultural cooperation.
Provided Britain with continuing influence, especially in Africa, Asia, and the Caribbean.
Commonwealth: A voluntary association of independent states, mostly former British colonies, that cooperate in political, economic, and cultural matters.
However, Britain’s influence was uneven:
Some states looked increasingly to other powers.
Britain’s role was tested by disputes over apartheid in South Africa and other issues.
The organisation allowed Britain to maintain symbolic global leadership without the burdens of empire.
Changing Attitudes to Empire
From the 1950s onwards, British attitudes to empire shifted:
Acceptance that imperial control was unsustainable.
Focus turned to Europe and the USA as key partners.
The Commonwealth became a substitute for direct colonial power, reflecting a transition to a post-imperial identity.
Overall Significance of Crises and Decolonisation
The Korean War and Gulf War highlighted Britain’s reliance on collective international action.
The Suez Crisis showed the collapse of Britain’s ability to act independently on the world stage.
The Falklands War temporarily revived imperial confidence but did not reverse long-term decline.
Decolonisation transformed Britain into a post-imperial power, with the Commonwealth as its new global network.
