Western Sahara is a disputed territory on the northwest coast and in the Maghreb region of North and West Africa. About 20% of the territory is controlled by the self-proclaimed Sahrawi Arab Democratic Republic, while the remaining 80% of the territory is occupied and administered by neighboring Morocco. Western Sahara is a sparsely-populated area of mostly desert situated on the northwest coast of Africa. A former Spanish colony, it was annexed by Morocco in 1975. Since then it has been the subject of a long-running territorial dispute between Morocco and its indigenous Saharawi people, led by the Polisario Front.
