In 1820, King Radama of Imerina, Madagascar signed a treaty allowing approximately one hundred young Malagasy to train abroad under official British supervision, the so-called ‘Madagascar Youths’. In this lively and carefully researched book, Gwyn Campbell traces the Youths’ untold history, from the signing of the treaty to their eventual recall to Madagascar. Extensive use of primary sources has enabled Campbell to explore the Madagascar Youths’ experiences in Britain, Mauritius and aboard British anti-slave trade vessels, and their instrumental role in the modernisation of Madagascar. Through this remarkable history, Campbell examines how Malagasy-British relations developed, then soured, providing vital context to our understanding of slavery, mission activity and British imperialism in the nineteenth century.
