​This study is about the state-building impasse in the Arab World in General, and in Libya in particular. These states have suffered, since the beginning of the Arab Spring, from lack of political prospects, eruptions of civil wars, and obstacles of political settlements among different actors in the public space. These elements have inhibited the achievement of state building, the formation of a pluralist political system and the realization of an integrated national identity. This study endeavors to analyze the obstacles that have obstructed state-building in Libya until now. It focuses on tribalism and regionalism as main obstacles to that process. In addition, it analyzes the role of external factors and actors in the light of tribalism and regionalism. It argues that state-building in Libya has stumbled and has not followed a gradual path of modern state-building and formation, and it has not gone through the necessary stages of political transition. The former has trapped Libya within narrow loyalties which are short of the wider loyalties necessary for the national state.
