Mauritania

One of Africa's newest oil producers, Mauritania bridges the Arab Maghreb and western sub-Saharan Africa.

The largely-desert country presents a cultural contrast, with an Arab-Berber population to the north and black Africans to the south. Many of its people are nomads.

In the Middle Ages Mauritania was the cradle of the Almoravid movement, which spread Islam throughout the region and for a while controlled the Islamic part of Spain. European traders began to show interest in Mauritania in the 15th century and in 1814 it came under direct French rule.

Morocco opposed the country's independence in 1960 and for a time tried to absorb it. But Morocco's King Hassan II later improved ties as part of his plan to divide Western Sahara.

The eventual deal in 1976 brought more problems, though, with Mauritania coming under attack by Polisario Front guerrillas, who opposed Moroccan control of Western Sahara, and the subsequent downfall of the leader since independence - Moktar Ould Daddah - in a military coup.

Peace was agreed with the Polisario in 1979, but this in turn worsened relations with Morocco, until a detente in 1985. More recently, ties with Senegal have been strained over the use of the Senegal River, which forms the border between the two countries.

Mauritania officially banned slavery in 1981. The government has denied accusations that it is still being practised.

One of the world's poorest countries, Mauritania has pinned hopes for future prosperity on the exploitation of its offshore reserves of oil and natural gas. The Chinguetti and Tiof fields are expected to yield millions of barrels of oil.

The country forged diplomatic ties with Israel in 1999, one of three Arab nations to have done so. Under its former president, Mauritania was an ally of the US in its "war on terror". American special forces were despatched to train Mauritanian troops.
