Western Sahara, formerly the Spanish colony of Spanish Sahara, is a disputed territory claimed by both the Kingdom of Morocco and the Popular Front for the Liberation of the Saguia el Hamra and Rio de Oro, which is an independence movement based in Tifariti and Bir Lehlou. The Annexation of Western Sahara by Morocco took place in two stages, in 1976 and 1979, and is considered illegal under international law.

Western Sahara is a disputed territory on the northwest coast of Africa. About 20% of the territory is controlled by the Sahrawi Arab Democratic Republic (SADR); the remaining 80% is occupied and administered by neighboring Morocco. It has a surface area of 266,000 square kilometres (103,000 sq mi). It is the second most sparsely populated country in the world and most sparsely in Africa, mainly consisting of desert flatlands. The population is estimated at about 500,000, of which nearly 40% live in Morocco-controlled Laayoune, the largest city in Western Sahara.
