Decolonisation in Africa

ZIMSEC A Level · History · Form 6

Causes

African nationalism (educated elites, ex-servicemen, trade unions), the impact of the Second World War, the Atlantic Charter and UN pressure, the weakened European powers, the Cold War, and pan-Africanism (Manchester Congress, 1945).

Patterns

  • Peaceful transfers: Ghana (1957 – Kwame Nkrumah's CPP and positive action), Nigeria (1960), Tanganyika (1961).
  • Armed struggles: Kenya (Mau Mau, 1952–60), Algeria (1954–62), Portuguese colonies – Guinea-Bissau, Angola and Mozambique (1975), Zimbabwe (1980), Namibia (1990).
  • South Africa: apartheid (from 1948) ended through internal resistance, sanctions and negotiations, with democratic elections in 1994.

Pan-Africanism and the OAU

The Organisation of African Unity (1963) supported liberation movements; it was replaced by the African Union (2002).

Post-independence challenges

Neo-colonialism, one-party states, military coups, ethnic tensions, debt and economic dependency.

Exam tip: Compare case studies – why was decolonisation peaceful in some colonies but violent in others (settler presence, metropole policy)?
