Tishio la Ukombozi examines the role of the Umma Party of Zanzibar and its leader in the turbulent years of the Zanzibar revolution of the 1960s that was perceived in those Cold War years as a threat to the interests of the US and Europe. Based on declassified US and British documents, in-depth interviews and information released by WikiLeaks, Amrit Wilson offers an insightful and compelling analysis of the struggle against neo-colonialism as it played out in Zanzibar and what is now Tanzania. She introduces the reader to the movement that built unity across ethnic divisions and could have brought about the revolutionary transformation of Zanzibar and beyond. The book considers the contemporary relevance of such struggles in the context of the 'War on Terrora' in East Africa.
