What are the real main determinations provoking interethnic conflict which has shook the Mzab Valley? To answer, we are obliged to borrow an oddly itinerary, which makes the way from philosophy to anthropology, transiting through economy, history and political geography. Observers point out apparent logics to explain the conflict between Chaambas and Mozabites, these parties have various dissimilarities: ethnic (Arabs / Berbers), sociological (sedentary / nomadic) and tribal (clan / tribe).

As concerns the underlying logics, it is a question of frustrations tested by chaâmbis masses for which one incident / pretext (foot ball match, election deadline, house attribution, etc.) is enough for an interethnic clash triggering. To understand these accumulated frustrations, we must follow the events’ progress in the valley Mzab through the story, as well as reading again the National Liberation War chapter, when Mozabites, escaping from the colonial army’s repression, came to install their tents around Ghardaia. The independence, then "socialist revolution", have also caused other changes (tents become houses, etc.), showing a reversal of social hierarchies and pre - eminence links for Chaâmbis.

Meanwhile, the new middle level, issued on the Arabic community already dominating the state structures (administration, justice, etc.), extends its control through the city and its symbols. Land access is the fundamental challenge at the origin of the area’s clashes. In the presence of the crisis’s material bases: unemployment, poverty and social exclusion, violence means "subversion of the State national form." From then on, how to take charge of these "critical abscess" that stand good chance of serving as a relay for foreign interference imposing an «Arab Spring"? All the more since the material and human resources (geostrategic encirclement, economic crisis, etc.) exist in Algeria.
