The Weberian principle of the state as possessing a legitimate monopoly on violence is fading. Sovereigns no longer hold this monopoly; it now belongs to the international community. This chapter investigates the effects of this fading of legitimacy. Expanding on a framework suggested by the Copenhagen School of international relations, the chapter argues that the Kosovo war is a crucial part of two on-going shifts. In Kosovo, the states going to war as the North Atlantic Treaty Organisation (NATO) Alliance represented themselves as 'humanity', the implication being that Serbia was cast as an enemy not only of human rights but of humanity. The Kosovo war defines the epoch exactly because it focused on the simultaneously existing conflict lines upon which politics is constituted. Serbia's attempts to legitimise its stance as a warring state defending the idea of state sovereignty was represented as an anachronism.
