The big idea: Post-colonial theory is the theory that says the history of empire still shapes today's world. The old divide between colonisers and colonised did not vanish when empires ended — it lives on in global inequality and in whose ideas count.
Post-colonial theory is the 'remember empire' lens. It argues that you cannot understand today's rich–poor divide, or global politics, without the colonial past — because the wealth, borders and power of today were built by centuries of empire.
- Empire still matters — colonialism's effects did not end with independence.
- Global inequality has colonial roots — the Global North–Global South divide traces back to empire.
- Whose ideas count — mainstream theories reflect a Western viewpoint and marginalise others.
- Ongoing domination — economic and cultural control can continue after formal empire ends.
Independence was not a clean break: When colonies became independent, they inherited borders, economies and institutions designed to serve the empire, not them. Post-colonial theory says this legacy — not just present-day choices — helps explain why the former colonial powers are rich and many former colonies are poor.

A clear example of empire's lasting effects is the borders of Africa — lines drawn by Europeans that still shape conflict today.
Case study — colonial borders in Africa: In the late 1800s, European powers divided Africa among themselves, drawing borders to suit their own interests — often straight lines that split ethnic groups apart or forced rival groups together, ignoring the people who lived there. When African states became independent, they were left with these arbitrary borders, which have contributed to conflict and instability ever since.
This shows the post-colonial point: a problem that looks 'internal' today has colonial roots. The borders were not chosen by Africans but imposed by empire — so understanding the conflict means understanding the history, not just the present.
The key point: Post-colonial theory explains global politics through the legacy of empire. Africa's colonial borders show why: today's inequalities and conflicts are shaped by a past of domination — so a full picture must include the history the other theories often ignore.

Does post-colonial theory expose a crucial history others ignore, or does it over-blame the past? Weigh both sides.
Link it up: Post-colonial theory links straight to development (the North–South divide), power (who dominates whom, and how) and the HL theme of equality. In an essay, use it to challenge theories that ignore history and whose viewpoint counts.
How post-colonial theory comes up in Paper 1: A Paper 1 source might involve rich and poor countries or the shadow of empire. Bring the post-colonial lens: how does the legacy of colonialism still shape this today?
With reference to a source and one example you have studied, explain how post-colonial theory sees global politics.

Easy marks to lose: 1. Saying empire is 'just history'. The point is it still shapes today.
2. Forgetting the North–South divide. That is a key link.
3. No real example. Use colonial borders in Africa.
4. Ignoring the 'whose ideas count' point. It critiques a Western viewpoint.
