Southern Sudan [PDF ebook] 
The Problem of National Integration

First Published in 1972. The purpose of this book is to further understand the problems of the Southern Sudan, which have often been unfairly equated with the prevalent problems of national integration facing post-Colonial Africa. For greater understanding of the history and the contemporary manifestations of the conflict between North and South in the Sudan, the focus here is upon the generic aspects of this problem.
