Flags of Mauritania

Islamic Republic of Mauritania (current flag)

Who & why: a constitutional referendum on 5 August 2017, under President Mohamed Ould Abdel Aziz, approves a package of amendments that includes adding a red stripe along the top and bottom edges of the national flag; the new design is formally adopted later that month. The government's stated rationale ties the red to the blood shed by Mauritanians in the struggle for independence and in defense of the homeland; the change is also widely read by commentators, inside and outside the country, against the backdrop of Mauritania's long and unresolved reckoning with slavery, though that reading was not the government's official framing.

What it represents: the same green field, gold crescent, and gold star flown since 1959, now bordered top and bottom by narrow red stripes — the only change made to the flag since independence.

Islamic Republic of Mauritania (original flag)

Who & why: French Mauritania becomes an autonomous republic within the French Community in 1958 and adopts this flag on 1 April 1959, a year and a half before full independence arrives on 28 November 1960 under founding president Moktar Ould Daddah. The young republic inherits deep internal divisions between its Bidhan (Arab-Berber) elite and Haratine and Sub-Saharan African populations, including a system of hereditary servitude with roots in the pre-colonial emirates; slavery is nominally abolished by decree in 1981, but Mauritania does not make it a specific criminal offense until a law passed in 2007 — the last country in the world to formally criminalize it.

What it represents: the crescent moon and five-pointed star are shared Islamic symbolism, here rendered in gold on green, both colors strongly associated with Islam; the flag was chosen deliberately without French tricolor influence to mark a clean break from colonial rule.

French Mauritania

Who & why: starting in 1902–03, French official Xavier Coppolani negotiates protectorate treaties with the Trarza and Brakna emirs in a campaign of "peaceful penetration"; France formally establishes the Territoire civil des pays maures in 1904 as part of French West Africa (Afrique occidentale française). Military resistance continues in the north, notably from the Adrar emirate, and is not fully subdued until roughly 1912; the territory is administered from Saint-Louis, Senegal for most of this period, with the small outpost of Nouakchott only developed as a proper capital from 1958 onward, just before independence.

What it represents: as an ordinary French colonial territory, Mauritania flew the plain French Tricolor, with no distinct territorial flag of its own.

Fragmented tribal emirates (Trarza, Brakna, Tagant, Adrar)

Who & why: after the Almoravid dynasty collapses when Marrakesh falls to the Almohads in 1147, its western Saharan homeland fragments again and never reunites under one crown. Between the 15th and 17th centuries, Arab Maqil tribes (the Beni Hassan) migrate in from the north and, after prolonged conflict culminating in the 17th-century Char Bouba war, impose Hassaniya Arabic and a rigid Bidhan (Arab-Berber) social hierarchy over the Sanhaja Zenaga Berber population — a hierarchy that hardens into the region's long-standing system of hereditary slavery. Power consolidates into a handful of rival warrior emirates — Trarza, Brakna, Tagant, and Adrar — alongside many smaller, independent tribal confederations, with no overarching state until French conquest begins in 1902.

What it represents: no unified flag exists for this fragmented, multi-emirate era; individual tribal and emirate banners are not reliably documented well enough to reconstruct here. Shown honestly blank rather than invented.

Almoravid dynasty (al-Murabitūn)

Who & why: around 1040, the Sanhaja chieftain Yahya ibn Ibrahim, returning from pilgrimage to Mecca, brings the Maliki jurist Abdallah ibn Yasin back to the western Sahara to teach a strict reform of Islamic practice among the Gudala and Lamtuna Sanhaja. His followers organize around a ribat, a fortified religious retreat, and become known as al-Murabitūn — the Almoravids. Under Abu Bakr ibn Umar and then Yusuf ibn Tashfin, the movement expands explosively out of this Mauritanian homeland: founding Marrakesh in 1070, conquering Morocco and the western Maghreb, and crossing into Iberia in 1086 to defeat Alfonso VI of Castile at the Battle of Zallaqa, eventually ruling a vast empire stretching from the Sahara to Al-Andalus. It is the only medieval Islamic empire whose founding homeland lay within present-day Mauritania, and it collapses only when Marrakesh itself falls to the rival Almohads in 1147.

What it represents: no Almoravid state flag survives with certainty; early sources associate the dynasty's austere reform movement with plain white banners, in contrast to the black of the Abbasids or the later green of some rival dynasties. Shown here as an informed reconstruction on a plain field, not a documented specification.

Fragmented Sanhaja Berber confederations

Who & why: before the Almoravid movement coalesces, the western Sahara — roughly present-day Mauritania — is home to loosely organized Sanhaja Berber confederations, among them the Gudala, Lamtuna, and Messufa, who herd camels and control trans-Saharan trade routes carrying gold, salt, and enslaved people between West Africa and the Maghreb. No single ruler or state unites them. Islam spreads gradually among these confederations from the 8th century onward through trade contact with the Maghreb, setting the stage for the 11th-century reform movement that produces the Almoravids.

What it represents: no securely documented flag survives from this pre-heraldic era; trans-Saharan Berber confederations of this period are not known to have used fixed territorial banners. Shown here honestly blank rather than invented.

Green Sahara pastoralists & the Tichitt Tradition

Who & why: during the mid-Holocene "Green Sahara," when the region was savanna rather than desert, cattle-herding communities range across present-day Mauritania, leaving rock art still visible on the Tagant and Adrar plateaus. As the climate dries from around 2000 BCE, some of these communities build the stone-walled hilltop villages of the Dhar Tichitt escarpment (flourishing roughly 2200–200 BCE) — among the earliest known organized, densely clustered settlements in West Africa, sometimes described as the region's first proto-urban tradition. Continued desiccation empties the escarpment by the early centuries CE, scattering its population toward the Sahel and the Niger bend, where Sanhaja Berber confederations and the wider Soninke world (including the Ghana Empire) later take shape.

What it represents: no flag survives from any part of this prehistoric span; the rock art and dry-stone settlement walls that document it are not a heraldic record. Shown here honestly blank rather than invented.

World context: the Green Sahara's cattle-herding peak runs alongside the rise of Old Kingdom Egypt and its pyramid-building (c. 2600–2100 BCE) just across the same desert, and the Tichitt Tradition's stone settlements were still occupied while Egypt's New Kingdom pharaohs and the early Mediterranean Bronze Age civilizations flourished; the Sahara's final drying into the desert known today is substantially complete by the time this era ends.
