Until recently, the harsh desert expanse was inhabited primarily by the Sahrawis, a nomadic people of mixed Berber-Arabic and Black African descent. Western Sahara is an arid, sparsely populated territory running along the coast of northwest Africa south of Morocco and north and west of Mauritania. The Polisario Front governs the remaining inhospitable 15 percent, but tens of thousands of Sahrawis still reside in Algerian refugee camps. Western Sahara was a stateless territory lacking a central government when Spain occupied it in 1884. The Sahrawis themselves exhibited an "overwhelming consensus" for independence, according to the United Nations.
