This chapter examines the internal dimension of the Kosovo peace process, focusing on the integration of the Serb community from 1999 to 2025. Contrasting high-level diplomacy with the crisis of internal legitimacy, the chapter traces policy evolution through four eras: UNMIK’s “Standards before Status”, the Ahtisaari Plan’s decentralization, the Brussels era’s transactional integration, and the Kurti government’s “assertive sovereignty”. Applying ripeness, readiness, and spoiler theories, the analysis argues that a mutually hurting stalemate conducive to genuine integration never materialized. While recent measures, such as dismantling of parallel security structures, have secured unprecedented territorial control for Kosovo, they have resulted in “societal disintegration”. The chapter concludes that the current strategy of enforcing the rule of law without political accommodation has alienated the Serb minority, succeeding in policing the territory but failing to govern the population.
