History
The desert was home to nomadic Sahrawi tribes of Arab-Berber descent, herding camels and controlling caravan routes, with the caravan town of Smara as a religious centre. Spain claimed the coast in 1884 and consolidated the colony of Spanish Sahara in the twentieth century, developing phosphate mining at Bou Craa from the early 1970s.
As Spain prepared to withdraw in 1975, the International Court of Justice found no tie of sovereignty that would override the Sahrawis' right to self-determination. Morocco responded with the "Green March", sending some 350,000 civilians across the border to press its claim, and Spain handed administration to Morocco and Mauritania. The Polisario Front, backed by Algeria, declared the Sahrawi Arab Democratic Republic (SADR) and fought both. Mauritania gave up its share in 1979; Morocco took it and built a 2,700-kilometre defensive sand wall, the berm, sealing off roughly the western four-fifths of the territory — the useful part, with the coast, the towns, and the phosphates.
A United Nations-brokered ceasefire took effect in September 1991 and was meant to lead to a referendum on independence or integration, monitored and organised by a UN mission, MINURSO, which is still deployed on mandates the Security Council keeps renewing. The vote has never been held, snagged on who is eligible to take part. The SADR is a full member of the African Union and is recognised by 36 UN member states, while Morocco's autonomy plan has drawn growing international backing: the United States recognised Moroccan sovereignty in December 2020, France came out for the autonomy proposal in 2024 and the United Kingdom in 2025, and in October 2025 the Security Council pointed to that proposal as a basis for negotiations, saying genuine autonomy could be the most feasible outcome. In early 2026 the United States, with the UN, convened talks in Madrid and Washington between Morocco, the Polisario Front, Algeria and Mauritania; no settlement has been reached. Sahrawi refugees have lived for decades in camps near Tindouf in south-western Algeria; their number is disputed and politically charged, with Algeria citing about 165,000 and the UN refugee agency working to a lower figure. In November 2020 the Polisario declared the ceasefire over, and a low-intensity conflict along the berm has continued since.
- Western Sahara: The Last Colony — A stretch of Atlantic desert the size of Britain — a Spanish colony until 1975, then claimed by Morocco and Mauritania, fought over with the Polisario Front, and still, half a century later, the only African territory on the UN's list of non-self-governing territories
