Much writing about nineteenth century East Africa has been distorted by the legacy of post-Enlightenment thought as well as more insidious racist ideologies. Humanitarian lobbies throughout Western Europe, strongly influenced by positivist ideas, and campaigning to highlight the ravages of the slave trade, condemned Africa in their writings and propaganda to the periphery, outside "universal" history. Africa was reduced to a continent of slavery, in which the market, entrepreneurship and free wage labour could not exist. These ideas penetrated scholarly works and still survive in some guises. The consequence is that a variety of initiatives and forms of labour organization associated with the long distance trades in ivory and imported cloth have been overlooked by scholars, while the slave paradigm received widespread attention. Utilizing the conceptual tool of "crew culture" Rockel documents a large-scale African migrant labour system. Nyamwezi caravan porters from the interior, as well as coastal Zanzibaris and Waungwana, forged a unique way of life in which market values and experience of wage labour and the caravan safari combined with customarystandards and notions of honour derived from innovative reconceptualizations of tradition. The safari experience, commercial change, and interactions with peasant and pastoral communities along the trade routes, all contributed to the emergence of a unique East Africa modernity. This book can be read on various levels. It is at one and the same time a journey, a labour history, a story of African initiative and adaptation to modernity, and a contribution to a history of Tanzania and East Africa that gives due attention to intersocietallinkages, and networks.
