The Anti-Arab sentiments among Algerian Berbers (mainly from Kabylie) were always related to the reassertion of Kabyle identity. It began as an intellectual militant movement in schools, universities, and popular culture (mainly nationalistic songs). In addition to that, the authorities' efforts to promote development in Kabylie contributed to a boom of sorts in Tizi Ouzou, whose population almost doubled between 1966 and 1977, and to a greater degree of economic and social integration within the region had the contrary effect of strengthening a collective Amazigh consciousness and Anti-Arab sentiments.
