Book excerpt: The Swahili civilization was a fascinating and complex system_a group of advanced cultures with large economic networks, international maritime trade, and urban sophistication. This book documents the growth of Swahili civilization on the eastern coast of Africa, from 100 B.C. to the time of European colonialism in the sixteenth century. Using archaeological, anthropological, and historical information, Chapurukha M. Kusimba describes the origins of this unique and powerful culture, including its Islamic components, architecture, language, and trading systems. Incorporating the results of his own surveys and excavations, Kusimba provides us with a remarkable African-derived study of the rise and collapse of societies on the Swahili Coast.
