Moors reacted to the change, and to Arab nationalist calls from abroad, by increasing pressure to Arabize many aspects of Mauritanian life, such as law and language. A schism developed between those Moors who consider Mauritania to be an Arab country and those who seek a dominant role for the non-Moorish peoples, with various models for containing the country's cultural diversity suggested, but none implemented successfully.
This ethnic discord was evident during intercommunal violence that broke out in April 1989 (the “1989 Events” and “Mauritania-Senegal Border War”), but has since subsided. Some 70,000 black African Mauritanians were expelled from Mauritania in the late 1980s. The ethnic tension and the sensitive issue of slavery – past and, in some areas, present – is still a powerful theme in the country's political debate. A significant number from all groups, however, seek a more diverse, pluralistic society.
The government bureaucracy is composed of traditional ministries, special agencies, and parastatal companies. The Ministry of Interior spearheads a system of regional governors and prefects modeled on the French system of local administration. Under this system, Mauritania is divided into thirteen regions (wilaya), including the capital district, Nouakchott. Control is tightly concentrated in the executive branch of the central government, but a series of national and municipal elections since 1992 have produced limited decentralization.
Mauritania, along with Morocco, annexed the territory of Western Sahara in 1976, with Mauritania taking the lower one-third at the request of former imperial power Spain. After several military losses to the Polisario – heavily armed and supported by Algeria, the local hegemon and rival to Morocco – Mauritania retreated in 1979, and its claims were taken over by Morocco. Due to economic weakness, Mauritania has been a negligible player in the territorial dispute, with its official position being that it wishes for an expedient solution that is mutually agreeable to all parties. While most of Western Sahara has been occupied by Morocco, the UN still considers the Western Sahara a territory that needs to express its wishes with respect to statehood: a referendum is still supposed to be held sometime in the future, under UN auspices, to determine whether or not the indigenous Sahrawis wish to be independent as the Sahrawi Arab Democratic Republic, or to be part of Morocco. The Moroccan Government has thus far blocked such a referendum from taking place.
Col. Mustafa Ould Salek's CMRN junta proved incapable of either establishing a strong base of power or extracting the country from its destabilizing conflict with the Sahrawi resistance movement, the Polisario Front. It quickly fell to be replaced by another military government, the CMSN. The energetic Col. Mohamed Khouna Ould Haidallah soon emerged as its main strongman, and by giving up all claims to Western Sahara, he found peace with the Polisario and improved relations with its main backer, Algeria – but relations with the other party to the conflict, Morocco, and its European ally France, deteriorated. Instability continued, and Haidallah's ambitious reform attempts foundered. Not only was his regime plagued by attempted coups and intrigue within the military establishment, but it also became increasingly contested because of his harsh and uncompromising line against opponents and political and military dissidents, of whom many were jailed and some were executed.
In 1984 he was deposed by Col. Maaouya Ould Sid'Ahmed Taya, who relaxed the political climate somewhat, without relinquishing military control. Ould Taya moderated Mauritania's previous pro-Algerian stance, and reconnected with Morocco during the late 1980s. Relations with Morocco deepened during the late 1990s and early first decade of the 21st century, as part of Mauritania's drive to attract support from Western states and Western-aligned Arab states. However, Mauritania has not rescinded its recognition of Polisario's Western Saharan exile government, remaining on good terms with Algeria. Its position on the Western Sahara conflict is, since the 1980s, one of strict neutrality.
Mauritania's presidential election, its third since adopting the democratic process in 1992, took place on 7 November 2003. Six candidates, including Mauritania's first female and first Haratine (former slave family) candidates, represented a wide variety of political goals and backgrounds. Incumbent President Maaouya Ould Sid'Ahmed Taya won reelection with 67.02% of the popular vote, according to the official figures, with Mohamed Khouna Ould Haidalla finishing second.
During the late 1980s, Ould Taya had established a close co-operation with Iraq, and pursued a strongly Arab nationalist line. At the same time, bloody clashes erupted with Senegal in 1989, during which both countries expelled ethnic minorities to the other country. Mauritania grew increasingly isolated internationally, and tensions with Western countries grew dramatically after it took a pro-Iraqi position during the 1991 Gulf War. During the mid-to late 1990s, Mauritania shifted its foreign policy to one of increased co-operation with the US and Europe, and was rewarded with diplomatic relaxation and aid projects.
In 1999, Mauritanian Foreign Minister Ahmed Sid’Ahmed and his Israeli counterpart David Levy signed an agreement in Washington DC, USA, on 28 October, establishing full diplomatic relations with Mauritania. The signing ceremony was held at the U.S. State Department in the presence of U.S. Secretary of State Madeleine Albright. Mauritania thereby joined Egypt, Palestine, and Jordan as the only members of the Arab League to officially recognize Israel. Ould Taya also started co-operating with the United States in antiterrorism activities, which was criticized by human rights NGOs, who talked of an exaggeration and instrumentation of alleged terrorist activities for geopolitical aims.

The head of the Presidential Guards took over the president's palace and units of the army surrounded a key state building in the capital Nouakchott on 6 August 2008, a day after 48 lawmakers from the ruling party resigned. The army surrounded the state television building after the president fired two senior officers, including the head of the presidential guards. The president, the prime minister and the minister of internal affairs were arrested.
The coup was organized by General Mohamed Ould Abdel Aziz, former chief of staff of the Mauritanian army and head of the Presidential Guard, whom the president had just dismissed. Mauritania's presidential spokesman, Abdoulaye Mamadouba, said President Sidi Ould Cheikh Abdallahi, Prime Minister Yahya Ould Ahmed Waghf and the interior minister, were arrested by renegade Senior Mauritanian army officers, unknown troops and a group of generals, and were held under house arrest at the presidential palace in Nouakchott. In the apparently successful and bloodless coup d'état, Abdallahi's daughter, Amal Mint Cheikh Abdallahi, said: "The security agents of the BASEP (Presidential Security Battalion) came to our home and took away my father." The coup plotters, all dismissed in a presidential decree shortly beforehand, included General Muhammad Ould ‘Abd Al-‘Aziz, General Muhammad Ould Al-Ghazwani, General Philippe Swikri, and Brigadier General (Aqid) Ahmad Ould Bakri.
At 397,929 square miles (1,030,631 km), Mauritania is the world's 29th-largest country (after Bolivia). It is comparable in size to Egypt. It lies mostly between latitudes 14° and 26°N, and longitudes 5° and 17°W (small areas are east of 5° and west of 17°).
Mauritania is generally flat, with vast arid plains broken by occasional ridges and cliff-like outcroppings. A series of scarps face south-west, longitudinally bisecting these plains in the center of the country. The scarps also separate a series of sandstone plateaus, the highest of which is the Adrar Plateau, reaching an elevation of 500 meters . Spring-fed oases lie at the foot of some of the scarps. Isolated peaks, often rich in minerals, rise above the plateaus; the smaller peaks are called guelbs and the larger ones kedias. The concentric Guelb er Richat (also known as the Richat Structure) is a prominent feature of the north-central region. Kediet ej Jill, near the city of Zouîrât, has an elevation of 1,000 meters (3,281 ft) and is the highest peak.
Approximately three quarters of Mauritania is desert or semidesert. As a result of extended, severe drought, the desert has been expanding since the mid-1960s. To the west, between the ocean and the plateaus, are alternating areas of clayey plains (regs) and sand dunes (ergs), some of which shift from place to place, gradually moved by high winds. The dunes generally increase in size and mobility toward the north.
Mauritania has one of the lowest GDP rates in Africa, despite being rich in natural resources. However, a majority of the population still depends on agriculture and livestock for a livelihood, even though most of the nomads and many subsistence farmers were forced into the cities by recurrent droughts in the 1970s and 1980s. Mauritania has extensive deposits of iron ore, which account for almost 50% of total exports. With the current rises in metal prices, gold and copper mining companies are opening mines in the interior. The nation's coastal waters are among the richest fishing areas in the world, but overexploitation by foreigners threatens this key source of revenue. The country's first deepwater port opened near Nouakchott in 1986. In recent years, drought and economic mismanagement have resulted in a buildup of foreign debt. In March 1999, the government signed an agreement with a joint World Bank-IMF mission on a $54 million enhanced structural adjustment facility (ESAF). The economic objectives have been set for 1999–2002. Privatization remains one of the key issues. Mauritania is unlikely to meet ESAF's annual GDP growth objectives of 4%–5%.
Oil was discovered in Mauritania in 2001 in the offshore Chinguetti deposit. Although potentially significant for the Mauritanian economy, it remains to be seen how much it will help the country. Mauritania has been described as a "desperately poor desert nation, which straddles the Arab and African worlds and is Africa's newest, if small-scale, oil producer." There may be additional oil reserves inland in the Taoudeni basin, although the harsh environment will make extraction expensive.
Under the Abdallahi government there was a widespread public perception of governmental corruption and a lack of access to government information. Sexism, female genital mutilation (FGM), child labour, human trafficking, and the political marginalization of largely southern-based ethnic groups continued to be problems.
Following the 2008 coup, the military government of Mauritania faced severe international sanctions, internal unrest, and was accused by Amnesty International of practicing coordinated torture against criminal and political detainees. Amnesty has accused the Mauritania legal system, both before and after the 2008 coup, of functioning with a complete disregard of legal procedure, fair trial, or humane imprisonment. Further, Amnesty has accused the Mauritanian government of an institutionalized and continuous use of torture throughout its post independence history.
Life expectancy at birth was 53.91 years (2008 estimate). Per capita expenditure on health was 43 US$ (PPP) in 2004. Public expenditure was 2% of the GDP in 2004 and private 0.9 % of the GDP in 2004. In the early 21st century there were 11 physicians per 100,000 people. Infant mortality was 7.8 % of the live births.
The obesity rate among Mauritanian women is high, perhaps in part due to the local standards of beauty, in which obese women are considered beautiful while thin women are sometimes regarded as "sickly".
On 18 January 2011, the Islamic Leaders of Mauritania signed a fatwa, or Islamic Law, outlawing female genital mutilation.
The French occupied the country in 1860 in close cooperation with Maur religious leaders. Mauritania became a nation after the destruction of the kingdoms of Fouta Toro and Walo Walo and the Arab-Berber emirates of Trarza, Brakna, Taganet, and Adrar. As a result, the country has two main ethnic groups: black Africans and Arab-Berbers. The black African group includes the Fulani, Soninke, and Bambara. The Maurs include the Arab-Berbers (Beydan) and the black Maurs known as Haratin. White and black Maurs are Arab, whereas non-Arab blacks see themselves as African. The most important common denomination, if not the only one, is Sunni Islam.
Since 1999, all teaching in the first year of primary school is in Arabic, French is however introduced in the second year and all scientific courses are taught in French for everyone. The use of English and the Weldiya dialect is also on the increase. The country has the University of Nouakchott and other institutions of higher education, but the most highly-educated Mauritanians have studied outside the country. Public expenditure on education was at 10.1% of 2000–2007 government expenditure.
