8B.5 - Nationalism, decolonisation and migration

Nationalism and imperial expansion

Nationalism can justify extending a state's power or resisting rule by an outside power.

In nineteenth-century Europe, national prestige and competition helped support imperial expansion. Control of territories could be presented as evidence of national greatness, while strategic routes, resources and markets gave material incentives. Rival states competed for influence. Imperial narratives frequently treated their own institutions as superior, helping justify unequal rule; this ideology should be analysed, rather than repeated as a fact about colonised peoples.

The British Raj was direct Crown rule in the Indian subcontinent from 1858 to 1947. It governed diverse peoples who did not form one uniform cultural community. Military power, administration and transport integrated territory into an imperial system, but imperial sovereignty did not mean local populations freely consented to every decision. Nationalist movements could develop in opposition, seeking self-government and mobilising shared political identity across local differences.

Nationalism was not the sole motive for empire, nor were colonised societies passive or unanimous. Economic interests, local alliances and military opportunities interacted with ideology. Later independence movements also disagreed about territory, religion and government. The same claim that a people should govern itself can unite a movement while leaving the boundary of that people contested.

Decolonisation and its costs

Decolonisation transferred political authority, but the route to independence and the later state-building process varied greatly.

After 1945, anti-colonial mobilisation, the weakened position of European powers and changing international attitudes supported the emergence of many new states. Harold Macmillan's 1960 “wind of change” speech acknowledged growing African national consciousness; the UK government's historical account links it to accelerated decolonisation. A speech illustrates changing policy, but does not mean that independence was granted by European leaders alone or that every transition was peaceful.

In Vietnam, French colonial rule ended following armed struggle and the 1954 defeat at Dien Bien Phu. The Geneva settlement divided the country temporarily; subsequent conflict involved Vietnamese political divisions and Cold War intervention. It is misleading to treat the entire later war as a single conflict between a colony and France. Sovereignty after the withdrawal of one imperial power did not guarantee peace or agreement over national government.

War can kill or injure people, displace households, interrupt education and destroy farms, transport and public infrastructure. These losses reduce production and consume resources needed for rebuilding. Environmental costs include damaged vegetation, contaminated land and dangerous remnants of war. The US Department of Veterans Affairs documents the use of Agent Orange and other herbicides during the Vietnam War to remove cover and crops; this is evidence of a mechanism of ecological and human harm, not a complete valuation of all war losses.

Transition costs must be explained with place and chronology. A negotiated independence may preserve more infrastructure than prolonged war, while an apparently orderly handover can leave unresolved exclusion or territorial disputes. Costs can persist long after the formal independence date and fall unevenly on particular regions and communities.

Post-imperial migration connections

The end of colonial rule does not erase the networks that connected a colony with the imperial centre.
