This book provides a unique comparative study of the major secessionist and self-determination movements in post-colonial Africa, examining theory, international law, charters of the United Nations, and the Organisation of African Unity (OAU)/African Union’s (AU) stance on the issue. The book explores whether self-determination and secessionism lead to peace, stability, development and democratisation in conflict-ridden societies, particularly looking at the outcomes in Eritrea and South Sudan. The book covers all the major attempts at self-determination and secession on the continent, extensively analysing the geo-political, economic, security and ideological factors that determine the outcome of the quest for self-determination and secession. It reveals the lack of inherent clarity in international law, social science theories, OAU/AU Charter, UN Charters and international conventions concerning the topic.This is a major contribution to the field and highly relevant for researchers and postgraduate students in African Studies, Development Studies, African Politics and History, and Anthropology.
