The Sahrawi Arab Democratic Republic, also known as the Sahrawi Republic and Western Sahara, is a partially recognized state, recognized by 46 UN member states and South Ossetia, 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. Between 1884 and 1975, Western Sahara was known as Spanish Sahara, a Spanish colony. The SADR is one of the two African states in which Spanish is a significant language, the other being Equatorial Guinea.

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.
