The book finishes with an epilogue that shows how examining encounters in the deep interior helps to further contextualise one of the most well-known episodes in coastal East Africa’s nineteenth-century history, namely the urban riots of 1888 and the subsequent outbreak of the Abushiri Rebellion (1888–90).
