Professor Stephen Constantine (Lancaster University) presents research on migration within the British world and the effects it has on the marginalisation of different social groups. Professor Stephen Constantine, of Lancaster University, presents research, included in his recent work with Marjory Harper, 'Migration and Empire' (a part of the Oxford History of the British Empire series), on migration within the British world. Prof Constantine's research examines marginal groups, the experiences and treatment of the marginalised, and, lastly, deportation and the marginalised. This engaging presentation spans the breadth of the empire, drawing significant conclusions about migration in all areas, both geographically and socially, of Britain's imperial world.
