Western Sahara, formerly Spanish Sahara, Territory, northwestern Africa. Area: 105,020 sq mi (272,000 sq km). Population: (2024 est.) 632,200. Capital: Laayoune. Little is known of the area’s prehistory, though rock engravings in southern locations suggest a succession of nomadic groups. In the 4th century bce there was trade across the Mediterranean Sea between the region and Europe, but there was little European contact afterward, until the 19th century. In 1884 Spain claimed a protectorate over the Río de Oro region. Boundary agreements with France were concluded in 1900 and 1912. Spain formally united the area’s northern and southern parts into the overseas province of the Spanish Sahara in 1958. The Polisario Front, a Saharawi separatist group formed in 1973, led an insurgency against Spanish colonial rule. In 1976 Spain relinquished its claim; the region then was divided between Mauritania and Morocco. That same year, the Polisario Front declared a government-in-exile, the Saharan Arab Democratic Republic. Sporadic fighting between Moroccan and Mauritanian forces and the Polisario Front began in the mid-1970s. Although Mauritania relinquished its claim in 1979, Morocco promptly annexed their portion. Despite a 1991 cease-fire and a number of United Nations-sponsored talks between the Polisario Front and the Moroccan government, at the beginning of the 21st century the issue of Western Sahara’s status remained unresolved. Western Sahara has vast phosphate deposits and some potash and iron ore.
