This book, The Political Economy of Integration and Disintegration in Africa: the Factor of External Interests, interrogates the political economy of state system in Africa from the ancient times, its external nexus, and the role of world politics in the transformation of the state system in Africa. It equally explores the processes and phases of the transformation, how the scramble for natural resources by external forces structured the character of modern African state system, and how they combined to shape Africa s position in international politics. The book therefore attempts a study of the cosmopolitization of African state system through integration and the role of external interests in its continued disintegration.
