Western Sahara (EH in ISO 3166-1) is a region of northwestern Africa. Morocco virtually annexed the northern two-thirds of Western Sahara (formerly Spanish Sahara) in 1976, and the rest of the territory in 1979, following Mauritania's withdrawal. A guerrilla war carried by the Polisario Front contesting Rabat's sovereignty ended in a 1991 cease-fire; a referendum on final status has been repeatedly postponed.
