Volume VII - Africa under Colonial Domination 1880-1935, edited by A. Adu Boahen (1985), has 30 chapters on the comparative analysis of European colonial systems and the multifaceted response of African societies, including the emergence and development of nationalist movements.  
Volume VIII - Africa since 1935, edited by Ali A. Mazrui and C. Wondji (1999), has 30 chapters and seven themes. It explores the effects of major world crises and their impacts on the emergence and development of African nationalisms, pan-Africanism, the struggle for liberation and the place of independent African countries on the world scene.  
Unfortunately, the impressive achievement of the GHA project was not widely disseminated in African bookstores, libraries or research institutions. Its impact on history curricula was virtually non-existent in most, if not all, African countries. A new initiative was necessary. The opportunity for launching that new initiative was found on 9 September 1999, with the Sirte Declaration, the founding act of the Organization of African Unity (OAU), which changed its name to the African Union (AU) in 2002.
