Ubari, an oasis town in southern Libya’s Fezzan region, is home to members of both the Tuareg and Tubu tribes. These two tribes dominate this corner of Libya and contiguous desert regions in neighbouring countries. For over a century, relations between these tribes were peaceful, governed by an 1893 treaty known as the ‘Midi Midi’. The 2011 revolution in Libya did more than simply bring down the Qaddafi regime; it also brought down the intricately structured relationships of patronage and power that had kept the region firmly under central government control.
