The '''Sahrawi Arab Democratic Republic''' (; '''SADR'''; also romanized with '''Saharawi''';  '''' ), also known as '''Western Sahara''', is a partially recognized ''de facto'' sovereign 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. 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.
