So far, most of the philosophical literature on occupations has tried to assess the legitimacy of military rule in the aftermath of armed conflicts by exclusively employing the theoretical resources of just war theory. In this paper, I argue that this approach is mistaken. Occupations occur during or in the aftermath of wars but they are fundamentally a specific type of rule over persons. Thus, theories of political legitimacy should be at least as relevant as just war theory for the (...) moral evaluation of occupations. This paper, therefore, draws on both traditions and argues that just war theory plays a limited role in identifying the purposes and appropriate agents of occupation authority, but that theories of legitimacy are necessary for explaining why and under which conditions foreign actors have the right to rule in the aftermath of armed conflicts.
