Most cases of historical injustices that attract public attention are at least partly caused by states. However, there is not yet a universally agreed upon, single version of a normative account that addresses all associated problems. In this paper, I attempt to defend the State Endurance Account as part of a response to the question of how we should account for reparations for state-caused historical injustices. This account supports the view that, in general, it is justified to require a state to fulfill its duties incurred in the past, including reparatory duties.
