The Tubus are a diversified pastoral nomadic people who speak two very similar dialects and form a single cultural community, extending from the Fezzan and the Kufra oasis in Southern Lybia, to the Tibesti and Ennedi mountains, to other Saharan and Sahelian territories of the Republic of Tchad, and to the eastern part of the Republic of Niger. The Tubus are now present in territories where Neolithic people left - for many thousands of years - an important number of traces of their life: tools, wall engravings and paintings, and stone monuments of the sort generally defined as 'pre-Islamic'.
