A large part of the Arab world is characterized by the disruptions of the states, the structures of which are weakened and sometimes even deliberately jeopardized. The most palpable and prejudicial challenges to these states attack the exercise of sovereignty on their territories. Indeed, we can notice the apparition, or the return, and the affirmation of territorialities that are presented as inherently incompatible with the existence of nation-states and which are then undermining its primary foundation: its territorial base and its control over it. In this regard, Libya represents the most complex and paroxysmal case. Even if violence is significantly lower than in Syria or Yemen, fragmentation is at a far higher stage than anywhere else in the Arab world. This article aims to study the process of fragmentation in Libya at its different scales.
