Offensive neorealism in literature, whose main principles are considered to be described in John J. Mearsheimer’s work titled “The Tragedy of Great Power Politics”, presents a perspective which is pessimistic and close to the classical realism to the behaviors of states in the international system. This theory forms the theoretical basis of this study. In the study, within the scope of offensive neorealism, the independence-oriented policies of the Republika Srpska, which has constitutionally an entity status in Bosnia-Herzegovina, are discussed. The constitutional order established with the Dayton Agreement in Bosnia-Herzegovina, one of the geographies where the international relations discipline was most concentrated in the post-Cold War period, created a problematic order that both affected the fate of the country and closely concerned the international community. The constitutional order of Bosnia and Herzegovina and the distrust of the ethnic elements that make up the country are important problems in the region. In addition, it is seen that Serbian nationalism is increasingly emphasized by the Republika Srpska. It is foreseen that the policy makers of Republika Srpska, especially Milorad Dodik, will continue to maintain this attitude in the future. It has been concluded that the policies followed by the Republika Srpska for independence in this order largely confirm Mearsheimer's offensive neorealist assumptions.
