Tiris al-Gharbiyya
Mauritanian President Mohamed Khouna Ould Haidalla in 1984 proceeded to recognize the Polisario-backed Sahrawi Arab Democratic Republic (SADR) as the legitimate sovereign of the area.Western Tiris was the lower half of Río de Oro, the southern province of the former Spanish Sahara, comprising 88,000 km (55,000 mi)[5] with a population of 12,897.While some reports indicate the territory may hold important quantities of mineral resources such as iron – and there is speculation, but no proof of, off-shore oil – the raging war prevented any serious exploration efforts.The Ould Daddah government's claims to the territory was based in the strong cultural and tribal ties between the Moorish inhabitants of Mauritania, and the tribes of Western Sahara.Before of the International Court of Justice, Mauritania claimed in 1975 that the entire Spanish Sahara had historically constituted part of "Bilad Chinguetti", which it argued had been an undeclared tribal and religious community.
