Why did the British Empire grow and contract?

The idea

The expansion and subsequent contraction of the British Empire between 1857 and 1967 were driven by shifting economic, strategic, and political forces. Growth during the late nineteenth century, such as the Scramble for Africa, was fuelled by the search for new markets, raw materials, and strategic imperatives like securing the Suez Canal route to India. Conversely, contraction accelerated after the Second World War due to Britain's severe economic exhaustion and the changing global geopolitical climate. The rise of organised nationalist movements, exemplified by the Indian National Congress and the Mau Mau rebellion in Kenya, made maintaining imperial control financially and militarily unsustainable, forcing rapid decolonisation.

What earns the marks

• Identify economic drivers for expansion, such as the need for raw materials and new markets during the late Victorian era.
• Explain the strategic motivations for growth, including the protection of existing trade routes like the Suez Canal.
• Analyse the impact of the World Wars on Britain's economic capacity to maintain its empire, leading to contraction.
• Evaluate the role of indigenous nationalist movements in forcing decolonisation and imperial retreat.

Common mistakes and how to put them right

• Treating the empire's growth as a single, planned strategy rather than a series of reactive and opportunistic acquisitions.

  Put it right: Recognise that expansion was often driven by 'men on the spot'.

• Assuming contraction only began after 1945.

  Put it right: Acknowledge that the seeds of decolonisation, such as the Statute of Westminster in 1931, were sown much earlier.

• Ignoring the role of the colonised peoples in contraction.

  Put it right: Ensure nationalist movements are credited alongside Britain's economic decline.

Exam tips

• Always link specific territorial acquisitions or losses to broader economic or strategic themes rather than just narrating events.
• Use the concept of 'informal empire' to show how British influence grew beyond formal territorial control, particularly in South America or China.
• When discussing contraction, weigh the relative importance of metropolitan weakness against peripheral pressure from nationalist uprisings.
