After his post-graduate studies, Fage joined the newly founded University of Gold Coast (now University of Ghana) at Accra, which was formed under the Asquith Commission and had a 'scheme of special relationship' with the University of London [REF].
In a long collaboration with Roland Oliver (who was his contemporary at Cambridge and visited him in Ghana), he founded the Journal of African History, and also edited the authoritative eight-volume Cambridge history of Africa, (1975 to 1986).
