My thesis will outline how power relations are constructed in instances of military conflict in northwestern Europe in Tacitus. I propose to analyze these in four chapters, each one devoted to a single geographical: the Batavian rebellion (Histories), the mutinies on the Rhine (and in Pannonia, Annals), battles in Britain (Annals and Agricola), and Germany (Annals and Germania). The two main lenses through which I am looking at the issue of power will be the construction of landscape and the discourses used by participants (on both sides) in situations of conflict with Rome.
