Caesar’s conquest of Gaul makes for a fascinating study in mass-violence in the ancient world. Caesar’s own narrative of his conquest, the Bellum Gallcium, provides us with one of our few first-hand accounts of conquest. Caesar’s keen political eye means that the narrative must be one he considered would resonate with a significant proportion of Romans. As such, it provides perhaps one of our best guides not so much as to what happened, but as to the place of mass violence within Roman thinking. Within the text, Caesar clearly states what can be regarded as a genocidal’ desire, namely that the ‘the stock and name of the tribe’ (stirps ac nomen civitatis) of the Germanic Eburones might be destroyed for their role in ambushing Caesar’s forces (Bellum Gallicum 6.34), as well as narratives of other acts of mass-killing. In addition, Caesar narrates several instances of mass-enslavement – an action that, although not readily caught by modern legal definitions of genocide, would have the same effect by dispersing a people, and causing the cessation of that people’s existence as a distinct group of people. However, Caesar’s text also shows a concern to portray such events as justified as within a retributive framework of wrongs done to Rome.
