The Sahrawi Arab Democratic Republic, also known as the Sahrawi Republic and Western Sahara, is a partially recognized state, located in the western Maghreb, which claims the non-self-governing territory of Western Sahara, but controls only the easternmost one-fifth of that territory. It is recognized by 46 UN member states and South Ossetia. Between 1884 and 1975, Western Sahara was known as Spanish Sahara, a Spanish colony (later an overseas province). The SADR is one of the two African states in which Spanish is a significant language, the other being Equatorial Guinea.
The SADR was proclaimed by the Polisario Front on 27 February 1976, in Bir Lehlou, Western Sahara. The SADR government calls the territories under its control the Liberated Territories or the Free Zone. Morocco controls and administers the rest of the disputed territory, and calls these lands its Southern Provinces. The claimed capital city of the SADR is El Aaiún (the capital of the territory of Western Sahara). Since the SADR does not control El Aaiún, it has established a temporary capital in Tifariti, although most of the day-to-day administration happens in Rabuni, one of the Sahrawi refugee camps located in Tindouf, Algeria.
The SADR maintains diplomatic relations with 46 United Nations states, and is a full member of the African Union. With a population of about half a million, it is the most sparsely populated in Africa, and the second-most sparsely populated in the world.
