Paris - At 93, Zimbabwe President Robert Mugabe is the last living African head of state to have fought for his country's independence from a colonial power before becoming its leader.He has used his aura of liberator to stay in power but has increasingly become seen as an oppressor, and Zimbabwe's military detained the veteran leader this week.Below are the main founding fathers of post-colonial Africa:Kwame Nkrumah, Ghana Born in 1909, Nkrumah fought on two fronts: for independence for the British Gold Coast and for pan-Africanism, calling for the creation of a United States of Africa.He was prime minister upon independence in 1957, becoming president in 1960 of what became Ghana.

Ahmed Sekou Toure, Guinea Toure was Guinea's dictatorial first president after independence in 1958 until his death in 1984.He was the only African nationalist leader to have rejected a Franco-African community proposed by General Charles de Gaulle, preferring outright independence to limited autonomy.
