The great Sahel droughts of the early 1970s caused massive devastation in Mauritania, exacerbating problems of poverty and conflict. The Arabized dominant elites reacted to changing circumstances, and to Arab nationalist calls from abroad, by increasing pressure to Arabize many aspects of Mauritanian life, such as law and the education system. This was also a reaction to the consequences of the French domination under the colonial rule. Various models for maintaining the country's cultural diversity have been suggested, but none have been successfully implemented.
