Mauritania

The territory of present-day Mauritania has been inhabited since prehistoric times, when a wetter Saharan climate supported pastoral and fishing communities whose rock art and stone tools survive across the Adrar and Tagant plateaus. As the desert advanced after roughly 2500 BCE, Berber-speaking groups moved southward and gradually displaced or absorbed earlier Bafour populations. From late antiquity onward, the region lay along trans-Saharan trade routes linking the Maghreb with the Sahel, and by the eighth and ninth centuries the Sanhaja Berber confederation had established the trading town of Awdaghust and exerted control over the salt and gold caravans crossing the western desert.

Between the eighth and eleventh centuries, the southern fringes of modern Mauritania formed part of the Ghana Empire, whose capital at Koumbi Saleh lay near the present border with Mali. In the mid-eleventh century, a religious movement among the Sanhaja gave rise to the Almoravids, who under leaders such as Abu Bakr ibn Umar and Yusuf ibn Tashfin extended their rule from the Senegal River across the Maghreb and into al-Andalus. Almoravid expansion accelerated the Islamization of the region, and after the dynasty's collapse the territory was contested by the Mali and later Songhai empires. From the late thirteenth century, successive waves of Arab Bedouin migration, culminating in the Maqil and Beni Hassan, transformed the social order; the Char Bouba war of the late seventeenth century established the dominance of Hassani warrior lineages and entrenched the Hassaniya Arabic dialect that remains widely spoken today.

European contact began with Portuguese trading posts on the Atlantic coast in the fifteenth century and continued through Dutch, English, and French commercial rivalry centered on gum arabic. France gradually extended influence inland during the nineteenth century, and after the campaigns led by Xavier Coppolani and Henri Gouraud in the early 1900s, Mauritania was constituted as a civil territory of French West Africa in 1920. Colonial administration was light and largely indirect, leaving traditional emirates such as Trarza, Brakna, Tagant, and Adrar in place under French oversight. The capital was administered from Saint-Louis in Senegal until Nouakchott was founded as a new federal capital in 1957.

Mauritania became an autonomous republic within the French Community in 1958 and achieved full independence on 28 November 1960 under President Moktar Ould Daddah, who consolidated a one-party state. After Spain's withdrawal from the Western Sahara in 1975, Mauritania annexed the southern portion (Tiris al-Gharbiyya) but renounced its claim in 1979 following a costly conflict with the Polisario Front. A 1978 coup ended civilian rule and inaugurated nearly three decades of military government under, successively, Mustafa Ould Salek, Mohamed Khouna Ould Haidalla, and Maaouya Ould Sid'Ahmed Taya, whose 1984 to 2005 tenure saw rapprochement with Israel, severe ethnic tensions with Afro-Mauritanian communities in 1989, and the formal abolition of slavery in 1981.

A bloodless coup in 2005 opened a brief democratic transition, but Mohamed Ould Abdel Aziz seized power in 2008 and won subsequent elections in 2009 and 2014. In 2019 his chosen successor, Mohamed Ould Ghazouani, won the presidency in what is generally cited as the country's first peaceful transfer of power between elected leaders, and he secured a second term in 2024. Mauritania today is an Islamic presidential republic with a multiparty parliament, governed under the constitution of 1991 as repeatedly amended.
