While the British were able to accomplish abolition in the trans-Atlantic world by the end of the nineteenth century, their efforts paradoxically caused a great increase in legal and illegal slave trading in the western Indian Ocean. Bringing together essays from leading authorities in the field of slavery studies, this comprehensive work offers an original and creative study of slavery and abolition in the Indian Ocean world during this period. Among the topics discussed are the relationship between British imperialism and slavery; Islamic law and slavery; and the bureaucracy of slave trading.
