Book excerpt: The Pan-Africanist debate is back on the historical agenda. The stresses and strains in the union of Tanganyika and Zanzibar since its formation some forty years ago are not showing any sign of abating. Meanwhile, imperialism under new forms and labels continues to bedevil the continent in ever-aggressive, if subtle, ways. The political federation of East Africa, which was one of the main spin-offs of the Pan-Africanism of the nationalist period, is reappearing on the political stage, albeit in a distorted form of regional integration. It is in this context that the present study is situated. Backgrounding the major dramas of the union of Tanganyika and Zanzibar this book studies the personalities involved and their politics, and includes an account of the Dodoma CCM conference that toppled President Jumbe. It is also a detailed legal analysis of the union incorporating powerful new material.
