What this topic is asking
Topic 8.5 covers decolonization after 1900, mainly after the Second World War. It asks you to explain the processes and methods by which colonized peoples won independence: negotiated, often nonviolent paths (as in India) versus armed liberation struggles (as in Algeria and Vietnam), the central role of nationalism, the violence of partition, and why methods differed across the colonized world.
What decolonization was
Negotiated and nonviolent independence
Some colonies won freedom largely through pressure, not war.
Armed liberation struggles
Other colonies had to fight.
Where colonial powers refused to leave, independence often came through armed struggle:
- Algeria. A long, brutal war (1954 to 1962) against France, in which hundreds of thousands died, ended in Algerian independence.
- Vietnam. Vietnamese forces fought the French (to 1954) and then became entangled in the Vietnam War against the United States, finally unifying under communist rule.
- Other wars. Liberation wars were fought in the Portuguese colonies, Kenya, and elsewhere.
The difference between negotiated and armed paths often depended on how fiercely the colonial power resisted and on local conditions, such as the presence of European settlers.
Partition and its violence
Independence was not always peaceful even when negotiated.
Decolonization sometimes required partition - dividing a territory along religious or ethnic lines - with terrible consequences. The partition of India in 1947 split British India into India and Pakistan, triggering one of history's largest migrations as Hindus, Muslims, and Sikhs fled across the new borders, accompanied by horrific communal violence that killed perhaps a million people. Partition and contested borders left lasting conflicts (such as over Kashmir), a reminder that independence often arrived with deep new problems, themes continued in Topic 8.6.

A Long Essay Question (LEQ), scored on the 6-point comparison rubric.
Thesis (1): "Methods of decolonization differed greatly, from the largely negotiated, nonviolent independence of India to the armed liberation struggles of Algeria and Vietnam, though all drew on nationalism and the postwar weakening of empire."
Contextualization (1): situate decolonization in the postwar exhaustion of empire and the spread of nationalism.
Evidence (2): Gandhi and Indian independence; the violent wars in Algeria and Vietnam; partition; African independence movements.
Analysis (2): explain HOW and WHY methods differed, then add complexity by linking the differences to the attitude of the colonial power and local conditions, while noting the shared role of nationalism.
