Farming and pastoral societies inhabit ever-changing environments. This relationship between environment and rural culture, politics and economy in Tanzania is the subject of this volume which will be valuable in reopening debates on Tanzanian history.

In his conclusion, Isaria N. Kimambo, a founding father of Tanzanian history, reflects on the efforts of successive historians to strike a balance between external causes of change and local initiative in their interpretations of Tanzanian history.

He shows that nationalist and Marxist historians of Tanzanian history, understandably preoccupied through the first quarter-century of the country's post-colonial history with the impact of imperialism and capitalism on East Africa, tended to overlook the initiatives taken by rural societies to transform themselves.

Yet there is good reason for historians to think about the causes of change and innovation in the rural communities of Tanzania, because farming and pastoral people have constantly changed as they adjusted to shifting environmental conditions.

The Demographics of Empire is a collection of essays examining the multifaceted nature of the colonial science of demography in the last two centuries. The contributing scholars of Africa and the British and French empires focus on three questions: How have historians, demographers, and other social scientists understood colonial populations? What were the demographic realities of African societies and how did they affect colonial systems of power? Finally, how did demographic theories developed in Europe shape policies and administrative structures in the colonies? The essays approach the subject as either broad analyses of major demographic questions in Africa’s history or focused case studies that demonstrate how particular historical circumstances in individual African societies contributed to differing levels of fertility, mortality, and migration. Together, the contributors to The Demographics of Empire question demographic orthodoxy, and in particular the assumption that African societies in the past exhibited a single demographic regime characterized by high fertility and high mortality.
