Over the last fifty years, Roland Oliver has been both a witness to the post-colonial history of Africa and a preeminent scholar of the continent’s pre-colonial history. Oliver was a young Cambridge graduate in 1947 when he took a newly created position at the University of London to research, and eventually teach, the pre-colonial history of Africa. Seeking from the outset to establish a unified conception of African history free from European frameworks, Oliver and his colleague John Fage went on to write the influential A Short History of Africa, found the Journal of African History, and co-edit the eight-volume Cambridge History of Africa.
