This page is for OCR A-level History Y320, From Colonialism to Independence: The British Empire, 1857–1965. It gives you the long story, but OCR also expects you to compare developments across the period and judge turning points. Keep asking: what changed, what continued, and did change happen everywhere in the same way?

The starting system in 1857

The British Empire was not one uniform organisation. India was partly ruled by the East India Company and partly through Indian princes. Settler colonies such as Canada and Australia were moving towards self-government for white settlers. Elsewhere Britain controlled ports, trade routes or local rulers without creating the same machinery of government.

British power depended on ships, soldiers and industrial wealth, but also on Indian troops, colonial officials, local allies, merchants and intermediaries. This made empire powerful and vulnerable: Britain could rule vast territories with relatively few British people only while enough local groups cooperated or were unable to defeat it.

Five terms to learn first

• Colonialism: political control of a territory and its people by an outside power.
• Informal empire: economic or diplomatic dominance without complete annexation.
• Settler colony: a colony in which substantial numbers of outsiders settle permanently.
• Nationalism: the belief that a people should govern their own nation.
• Decolonisation: the ending of colonial rule and transfer of sovereignty.

Small task 1

Why did British imperial rule depend on people from outside Britain as well as on British force?

Theme 1: how the purposes of empire changed

In the later nineteenth century, trade, strategic routes, competition with other powers, settler ambitions, missionary activity and personal initiatives all encouraged expansion. India remained central. The Suez Canal increased Egypt’s importance because it shortened communications with Asia. In Africa, commercial hopes and European rivalry interacted with decisions made by officials, companies and settlers.

Britain did not always expand according to a plan made in London. Governments sometimes accepted new commitments reluctantly after local crises. Imperial policy could therefore be both deliberate and improvised.

By the twentieth century, defence and global strategy became increasingly expensive. The empire supplied troops and resources in two world wars, but these wars also weakened Britain. After 1945, policy increasingly focused on managing withdrawal, protecting strategic and commercial interests and transferring formal authority without losing all influence.

Small task 2

Identify one continuity and one change in the purposes of empire between the 1860s and the 1950s.

Theme 2: administration and control

The rebellion in India in 1857 ended East India Company rule. From 1858 India was governed in the name of the Crown, but British authority still relied on Indian soldiers, administrators, landlords and princes. This pattern—small British numbers working through local structures—appeared elsewhere too.

Different colonies had different constitutions. White settler dominions received substantial self-government while Britain retained strategic connections. Many Asian and African subjects had far less political power. This racial inequality was not accidental; it was built into ideas about who was supposedly ready to govern.

Communications technology strengthened control. Railways and telegraphs moved information, goods and troops. Yet administrative growth also created educated groups who could organise, publish and challenge colonial claims using the political language Britain itself promoted.

Small task 3

How could education and communications strengthen colonial government while also helping nationalism?

The first thematic foundation is unevenness: purposes, constitutions and methods of control varied across the empire.

Theme 3: economics, labour and development

Empire connected colonies to British and global markets. Colonies supplied raw materials and bought manufactured goods. Ports, railways, mines and plantations expanded. Some local merchants, landowners and workers found opportunities, but benefits were distributed unequally.

Economic policy often prioritised imperial trade, revenue or exports over local needs. Land could be transferred to settlers or companies. Taxes and labour demands changed rural life. Famines and depressions exposed the limits of colonial responsibility. It is therefore too simple either to deny that infrastructure was built or to treat infrastructure as proof that rule benefited everyone.

After the Second World War, Britain promoted colonial “development” more actively, partly to improve welfare and partly to make colonies economically productive and politically stable. Development could not remove the basic question of sovereignty: who had the right to set priorities?

Small task 4

Why must an answer about imperial economic development ask both what was built and who controlled or benefited from it?

Theme 4: resistance, cooperation and nationalism

Colonised peoples responded in many ways. Armed resistance occurred in India, southern Africa, Malaya and Kenya. Other groups negotiated, worked within imperial institutions or used courts, newspapers, unions and political parties. Cooperation did not necessarily mean approval; it could be a strategy for survival or advancement.

Nationalism changed over time. Early organisations sometimes asked for representation or reform rather than immediate independence. Mass politics expanded after the First World War. Gandhi’s campaigns in India used non-cooperation and civil disobedience. African and Asian leaders connected local grievances to wider ideas of self-determination.

British responses combined reform and repression. Limited concessions could create new expectations. Violence could restore short-term order while destroying legitimacy. Amritsar in 1919 and detention and abuse during the Kenyan Emergency show how coercion damaged claims of benevolent rule.

Small task 5

Explain why reform and repression could both strengthen nationalist opposition.

Theme 5: the world wars as turning points

The First World War mobilised imperial soldiers, labour and money. Britain gained mandates after victory, yet wartime sacrifice encouraged demands for greater political rights. The empire became larger but less secure.

The Second World War was a still greater turning point. Britain emerged economically exhausted. Japan’s conquest of Singapore and other colonies shattered European prestige in Asia. The United States and Soviet Union dominated the new international order, while anti-colonial movements possessed greater organisation and legitimacy.

War alone did not cause every independence. Local nationalism had deeper roots, and Britain sometimes resisted withdrawal for years. The wars changed the balance within which those movements operated.

Small task 6

Which world war was the greater turning point for the empire? Give one provisional reason, then note one limitation to your answer.

You may stop here

By 1945 the empire still existed, but the economic, military and ideological conditions that had supported it were badly weakened.

Theme 6: routes from colonialism to independence

India and Pakistan became independent in 1947 amid Partition, mass migration and terrible communal violence. The outcome reflected British haste and earlier policy, but also conflict and choices involving Congress, the Muslim League and many local actors.

Different territories followed different routes. Ghana moved to independence under Nkrumah through organised nationalist politics. Malaya combined war against a communist insurgency with negotiation and constitutional change. Kenya’s path included the Mau Mau uprising, emergency rule, detention and coercion. Settler interests complicated withdrawal in parts of Africa.

Suez in 1956 exposed Britain’s dependence on the USA and its reduced global power. Macmillan’s 1960 “Wind of Change” speech recognised the force of African nationalism. By 1965 formal empire had contracted dramatically, but military bases, commercial links and the Commonwealth preserved forms of British influence.

Small task 7

Why is there no single model of British decolonisation? Compare two territories.

How to think thematically

OCR questions may ask you to compare long stretches of time or judge the importance of a turning point. Avoid writing one event after another without comparison. Choose a test—such as the strength of British control, the scale of nationalism or the cost of empire—and apply it across several periods.

Small task 8

Using strength of British control as your test, compare 1857, 1919, 1945 and 1960 in four short notes.

Six anchor dates — learn these after the story

• 1857: rebellion in India.
• 1882: British occupation of Egypt.
• 1919: Amritsar massacre and post-war imperial expansion.
• 1942: fall of Singapore.
• 1947: Indian independence and Partition.
• 1960: “Wind of Change” speech.

What this first guide does not yet cover fully

You still need detailed case studies of administration, economics and resistance in India, Africa and other territories; dominion development; imperial defence; indigenous responses; both world wars; individual nationalist movements; the Commonwealth; and the full 1965 endpoint. You also need named historical interpretations and OCR thematic essays comparing developments across the whole period.

You may stop now

If you can explain why the empire was uneven, how its purposes and methods changed, why nationalism grew and why decolonisation followed different routes, you have a strong foundation.
