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. In the 1970s, the Sahrawi people led a successful revolt that culminated in Spain's beating a hasty retreat in 1975  only to have neighboring Morocco and Mauritania swoop in. Each considered the territory to have been arbitrarily split away from them by European colonialism. Western Sahara was a stateless territory lacking a central government when Spain occupied it in 1884.
