Africa in international politics on sub-regional systems basis offers researchers and students most peerless challenges and golden opportunities of looking at African political issues from different perspectives. Firstly, all epistemological and methodological approaches considered appropriate have been dealt with. Secondly, the novel scientific decision to follow a sub-regional systems approach as a special methodological approach in studying Africa in international politics does create a number of particular problems of epistemological, methodological and conceptual nature. Thirdly, the study produces a workable conceptual framework of material on Africa which enables imaginative and creative research scientist to methodically condense frighteningly voluminous data involved in a study of Africa on sub-regional systems basis. It further contains a division of Africa into five sub-regional systems comprising North Africa, West Africa, Central Africa, East Africa and Southern Africa. The book also scrutinizes Southern Africa in detail as one of five sub-regional systems. The book is, therefore, commended to scholars who are undertaking studies on Africa in international politics.
