Studies of slavery increasingly refer to ‘enslaved people’ rather than ‘slaves’, and, to a lesser extent, to ‘enslavers’ rather than ‘slave owners’. This trend began with scholarship in the United States on plantation slavery but has spread to other academic publications. Yet ‘slave’ continues to be widely used, indicating not everyone is aware of the change or agrees with it. Despite this, few historians have justified their terminology. After surveying the extent of the preference for ‘enslaved person’, I discuss arguments for and against it. Supporters of using ‘enslaved person’ argue that this term emphasises that a person was forced into slavery – but this emphasis means it is less able to accommodate early medieval cases where people sold themselves into slavery. The accompanying preference for ‘enslaver’ over ‘master’ obscures dynamics of ownership and manumission. In addition, ‘enslaved people’ and ‘enslaver’ do not necessarily bring us away from the perspective of slaveholders to the perspective of slaves. Nor are they essential for readers to appreciate the humanity of slaves. Overall, historians should use this issue as an opportunity to reflect on the extent to which scholarship of transatlantic slavery should set the terms of debate for slavery studies in general.
