This article explores and defines the concept of a `rogue’ state based on a state’s domestic patterns of behavior. It combines measures of domestic gender equality, ethnic discrimination, and state repression to identify characteristics of rogue states. Once it identifies rogue states, the article performs logistic regression to predict whether rogue states are more likely to be the aggressors during international disputes — whether they are more likely to use force first during interstate conflict, controlling for other possible causes of state use of force. This research adds to a growing body of scholarship in International Relations regarding the behavior of states involved in conflict, which demonstrates that states with higher levels of inequality, repression and violence exhibit higher levels of violence during international disputes and during international crises. This argument is most fully developed within feminist scholarship; however, research in the field of ethno-apolitical conflict has also highlighted the negative impact of domestic discrimination and violence on state behavior at the international level.
