Much has been written on the how colonial subjects took up British and European ideas and turned them against empire when making claims to freedom and self-determination. The possibility of reverse influence has been largely overlooked. Insurgent Empire shows how Britain's enslaved and colonial subjects were not merely victims of empire and subsequent beneficiaries of its crises of conscience but also agents whose resistance both contributed to their own liberation and shaped British ideas about freedom and who could be free. Insurgent Empire examines dissent over the question of empire in Britain and shows how it was influenced by rebellions and resistance in the colonies from the West Indies and East Africa to Egypt and India. It also shows how a pivotal role in fomenting dissent was played by anti-colonial campaigners based in London at the heart of the empire.
