Western Tiris was the lower half of
Río de Oro, the southern province of the former
Spanish Sahara, comprising with a population of 12,897. It consisted mostly of barren desert terrain, scarcely populated except by some thousands of Sahrawi nomads, many of whom had fled towards the Algerian
Tindouf Province in 1975. A few minor settlements dotted the coast, and the largest of these,
Dakhla (formerly Villa Cisneros), was made the provincial capital. 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. It remains mostly unexplored and unexploited to this day. The exception is the rich Atlantic fishing waters. They were never put to use by Mauritania, but have since been fished by Morocco and foreign ships under Moroccan licenses. The name "Tiris" refers to a desert plain of the
Sahara. Mauritania's northernmost province (in its internationally recognized territory) is similarly called
Tiris Zemmour, where "Zemmour" refers to a mountain range in central Western Sahara. 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. The government argued they were all part of the same people, and also put forth the notion of pre-colonial sovereignty by certain Mauritanian
emirates (tribal fiefdoms) over some of these tribes. 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. But it also recognized that there had never been a Mauritanian state to claim the territory, since Mauritania itself was a modern-day creation of
French colonialism. The court recognized the importance of these cultural links, but announced that they had not constituted sovereignty over the territory or its inhabitants before colonialism, and could not by themselves justify sovereignty today. Instead, it recommended a standard self-determination process where Sahrawis were given the choice of merger with Mauritania and/or Morocco, or independence. ==Present Mauritanian position==
