This article examines whether rogue states are more aggressive in challenging other states’ claims to territory in comparison with non-rogue states. Rogue states are defined as those which systematically violate accepted international human rights norms of gender and ethnic nondiscrimination and protection from state repression. Hypotheses suggest that states that regularly violate international human rights norms are more likely to challenge other states’ territorial claims and that dyads with rogue states are more likely to experience territorial claims. Empirical analyses of data from two datasets on territorial claims provide support to the theory. Territorial claims are more likely in politically relevant dyads as the potential challenger’s rogue state score increases. Territorial claims are also more likely to emerge as the minimum rogue state score in a dyad increases. The substantive effect of rogue status is sizable, increasing the chances for a territorial claim by as much as 500%.
