When African states gained independence in the 1950s and 1960s, many inherited borders drawn by European colonial powers with no regard for ethnic group boundaries. This left new governments trying to unite peoples who had little shared identity — a problem that, combined with weak institutions and economic strain, pushed several states towards conflict and military rule.
- Ethnic tensions — colonial borders often forced rival groups into one state (or split one group across two states), so post-independence politics became a struggle between ethnic blocs rather than parties with policies
- Economic problems — falling prices for cash crops and minerals, unemployment and food shortages created frustration that governments were blamed for, whether or not it was their fault
- Destabilization by outside forces — during the Cold War, the USA and USSR (and neighbouring states) funded, armed or encouraged rival factions to expand their own influence, turning local disputes into bigger armed conflicts
- Inefficiency of civilian governments — new governments often lacked trained administrators, relied on colonial-era structures built for extraction not development, and struggled to deliver services, fuelling public anger
- Ideology — disagreements between socialist, capitalist and traditionalist visions for the new state gave political rivals a further reason to distrust and undermine each other
- Personal ambition — individual leaders and army officers seeking power for themselves used the above problems as an excuse to seize control by force
Nigeria: the road to civil war (1966-1967): Nigeria's borders grouped together the Hausa-Fulani north, Yoruba south-west and Igbo south-east — three very different groups with little shared political trust. In January 1966, Igbo army officers overthrew the civilian government; a counter-coup in July 1966 put northern officers in charge, followed by violence against Igbo civilians living in the north. Fearing for their safety and excluded from power, Igbo leaders declared the independent state of Biafra in May 1967, starting the Nigerian Civil War (1967-1970).
Ghana: economic strain feeds instability: In Ghana, falling world cocoa prices and heavy government spending under President Kwame Nkrumah caused rising debt and shortages by the mid-1960s. Economic problems combined with accusations of one-party dominance and corruption gave the army a justification: in February 1966, while Nkrumah was abroad, military officers overthrew his government in a coup.
Always weigh causes, don't just list them: For Paper 3, don't stop at naming causes — explain how they connect. In Nigeria, ethnic tension and inefficiency of civilian rule combined; in Ghana, economic problems combined with personal ambition among army officers. Markers reward answers that show cause-and-effect chains, not a list.

Ethnic conflict, civil war and coups did not just remove one government and replace it with another — they reshaped African politics for decades, often replacing elected rule with military rule: government by army officers who suspended civilian constitutions.
Political impact
Constitutions were suspended, parliaments dissolved, and elections cancelled. Military leaders ruled by decree, often justifying this as temporary and necessary to restore order.
Human impact
Civil wars caused huge civilian death tolls (the Nigerian Civil War alone caused an estimated 1-3 million deaths, mostly from famine and disease in Biafra) and mass displacement of refugees.
Repression under military rule
Opposition parties were banned, the press was censored, and critics were imprisoned. Power and government contracts were often concentrated around the ruler and loyal army officers.
Long-term political impact
Once one successful coup showed power could be seized by force, further coups often followed — Nigeria had military coups in 1966, 1975, 1983 and 1985, delaying stable civilian democracy for decades.
Economic impact
War damaged infrastructure, farmland and trade; military governments often prioritised army spending over development, and international lenders grew wary of unstable states.
Coup topples government → military rules by decree → opposition crushed → next coup follows
Nigeria under military rule
- Civil war 1967-1970 devastated the south-east (Biafra)
- Repeated coups: 1966, 1975, 1983, 1985
- Long military rule under Sani Abacha (1993-1998): repression, executions of critics, delayed return to democracy until 1999
Ghana under military rule
- 1966 coup removed Nkrumah without a civil war
- Series of further coups followed (e.g. 1972, 1979, 1981)
- Jerry Rawlings ruled after 1981 coup, gradually allowing a return to multi-party elections by 1992
Impact ≠ just "bad things happened": For Paper 3, describe impact across categories: political (constitutions, elections), human (deaths, refugees), economic (infrastructure, spending) and long-term (pattern of repeated coups). This structure earns marks for range, not just detail.

Even where conflict was avoided, newly independent African states faced deep structural challenges left by colonial rule. These problems were both a cause of instability (feeding public anger at governments) and a consequence of it (wars and coups made existing problems worse).
- Disease — limited healthcare infrastructure inherited from colonial rule meant illnesses like malaria and, later, HIV/AIDS placed a huge strain on population and productivity
- Illiteracy — colonial education systems had reached only a small elite, leaving most citizens without the schooling needed to run a modern civil service or economy
- Poverty — most economies still relied on exporting a small number of raw materials (cocoa, copper, oil) at prices set by international markets, leaving little wealth for ordinary citizens
- Famine — droughts, war damage to farmland, and cash-crop farming replacing food crops left some regions unable to feed their populations
- Neo-colonial economic exploitation — former colonial powers and multinational companies kept effective economic control after independence, buying raw materials cheaply and selling manufactured goods back at a profit, keeping African economies dependent
Neo-colonialism: independence on paper, dependence in practice: Neo-colonialism explains why political independence did not bring economic independence. Ghana's cocoa and Nigeria's oil were still sold mostly to former colonial trading partners on terms set abroad, so world price falls (like the cocoa price collapse of the mid-1960s) directly caused government revenue crises at home.
| Challenge | Example in Ghana or Nigeria | Effect on government stability |
|---|---|---|
| Poverty / falling export prices | Ghana's cocoa price collapse, mid-1960s | Government debt rose sharply, feeding accusations of economic mismanagement |
| Illiteracy | Low school enrolment inherited from colonial rule in both states | Shortage of trained administrators to run ministries effectively |
| Famine | Wartime blockade of Biafra, Nigeria, 1967-1970 | Mass starvation became a symbol used internationally against the federal government |
| Neo-colonial exploitation | Oil profits in Nigeria largely benefiting foreign companies and a small elite | Ordinary citizens saw little improvement, deepening distrust of government |
Don't treat these as separate from the politics: A common error is describing disease, illiteracy, poverty and famine as background information only. For high marks, explicitly link them to instability: poverty and famine fed public anger → this anger was used to justify coups → coups and war then made poverty and famine worse.
