Mauritania National Flag: Vexillology, Historical Symbolism & Sovereign Guide

The high-resolution specimen displays the official sovereign state flag of the Islamic Republic of Mauritania, positioned in a crisp square digital studio framing. The flag layout is structured around a horizontal three-tier arrangement. The central and dominant visual zone is a broad field of deep, vibrant Saharan emerald green, which spans from the hoist on the left to the fly on the right. Framing this green central field along the upper and lower borders are two equal, parallel horizontal stripes of vivid scarlet red--one occupying the very top margin of the flag and the other anchoring the bottom foundation.

Positioned squarely within the geometric center of the emerald-green band are two radiant celestial charges rendered in brilliant golden yellow: an upward-facing crescent moon and a five-pointed star. Unlike standard crescent flags where the lunar horns point sideways toward the fly, the Mauritanian crescent is positioned horizontally like an open bowl, with its two pointed cusps curved gracefully upward toward the heavens.

Resting between the raised cusps of the golden crescent is an upright, symmetrical five-pointed star, with its top apex pointing directly toward the upper edge of the banner. The golden hue of the crescent and star shines brilliantly against the deep green backdrop, evoking a serene cosmic equilibrium. The red stripes on the upper and lower margins provide a decisive chromatic contrast against the cool green center, creating an authoritative, modern aesthetic that communicates both religious devotion and sovereign vigilance.

The spatial arrangement generates strong visual tension and stability. The horizontal red bands serve as structural lintels that enclose and protect the green interior sanctuary, while the upward orientation of the golden lunar horns directs the viewer's gaze toward the cosmic star at the meridian. Under intense Saharan sunlight, the contrasting green and red fields retain sharp visual demarcation, ensuring that the flag remains instantly recognizable from long distances across desert sand expanses and Atlantic coastal ports alike.

The statutory proportions of the national flag of Mauritania are codified at an aspect ratio of two units of vertical height to three units of horizontal width (2:3). Following the constitutional revision of 2017, the flag's vertical height is partitioned into six equal horizontal units. The upper red stripe occupies one unit (1/6th of total height), the central green band occupies four units (4/6ths, or 2/3rds, of total height), and the lower red stripe occupies one unit (1/6th of total height).

The celestial charges are mathematically centered within the green field. The golden crescent has an outer radius equal to approximately 1/4th of the flag's height, with its lowest point situated above the lower boundary of the green band. The five-pointed star is inscribed within a circle whose center is positioned directly between the two tips of the crescent.

The statutory colorimetric specifications of the Mauritanian flag are codified under Constitutional Law No. 2017-021:

Spectrophotometric analysis under standard CIE daylight conditions shows that the green ground delivers a dominant spectral wavelength of 530 nanometers, ensuring rich visual depth. The red stripes exhibit high chromatic purity with a dominant wavelength of 615 nanometers, while the golden star and crescent reflect peak luminous energy at 580 nanometers, maximizing legibility across desert sandstorms and bright Sahara skies.

The national flag of Mauritania possesses a distinctive constitutional history reflecting the dual identity of the nation as a bridge between the Arab Maghreb and Sub-Saharan West Africa. The original flag of Mauritania was drafted during the transitional autonomy period under Moktar Ould Daddah and was formally adopted on April 1, 1959, prior to full sovereign independence from France on November 28, 1960. That original 1959 flag consisted solely of the emerald green field bearing the upward golden crescent and star, without any red stripes.

The symbolism of the traditional colors is deeply embedded in Saharan Islamic civilization:

• Green (Vert): Represents Islam, the foundational spiritual identity and official religion of the state. It also symbolizes the fertile south along the Senegal River valley, agricultural hope, and oasis palm groves amidst the desert.
• Gold / Yellow (Or): Symbolizes the sands of the Sahara Desert, which cover over 75 percent of the national territory, as well as the mineral wealth of the country, including iron ore at Zouerat and ancient gold deposits.
• Upward Crescent & Star: The crescent and five-pointed star are universal symbols of Islam. The unique upward orientation--where the horns point toward the zenith rather than sideways--symbolizes the nation looking upward toward divine mercy, righteousness, and spiritual elevation.

On August 5, 2017, the national flag underwent a historic constitutional evolution. President Mohamed Ould Abdel Aziz sponsored a national referendum proposing constitutional amendments to modernize state institutions. Among the measures was a proposal to modify the national flag by adding two red horizontal stripes at the top and bottom. The official rationale was to honor the sacrifices of the resistance fighters and martyrs who gave their lives resisting French colonial occupation from 1902 to 1934, as well as soldiers who fell defending national sovereignty during the Western Sahara conflict and modern counter-terrorism operations.

The constitutional referendum passed with 85.6 percent approval, and on November 28, 2017--the 57th anniversary of national independence--the new flag with red bands was officially hoisted across the nation for the first time. The flag is constitutionally codified under Article 8 of the Constitution of the Islamic Republic of Mauritania, which states: "The national emblem is a flag bearing a crescent and a star of gold on a green background, with two horizontal red bands along the upper and lower borders."

The combination of green, red, and golden Islamic celestial charges requires precise vexillological differentiation from other Muslim and African sovereign flags:

Distinguishing Mauritania from Maldives

Both flags employ green and red fields with a crescent, but their architecture is fundamentally distinct:

1. 1Mauritania: Has red stripes only at the top and bottom, leaving the hoist and fly edges green, and features a Golden Upward Crescent cupping a Golden Star.
2. 2Maldives: Has a thick red border enclosing all four edges, and features a White Crescent pointing toward the fly with no star.

Distinguishing Mauritania from Algeria

Algeria divides its entire flag vertically into two equal halves of green and white, with a red crescent and star centered across the boundary. Mauritania is predominantly green with top and bottom red stripes and golden charges.

In fast-paced visual recognition rounds on PicRush, identify Mauritania with certainty using these five diagnostic steps:

1. 1Spot the Top and Bottom Red Bars: Look at the horizontal edges. If the flag has a green center bordered strictly at the top and bottom by red stripes, it is Mauritania. If the red border goes around all four sides, it is Maldives.
2. 2Verify the Upward-Facing Crescent: Examine the orientation of the crescent moon. Mauritania is one of the only sovereign flags where the crescent points directly upward (like a cup or bowl), cradling the star inside its horns.
3. 3Confirm Golden Celestial Color: The crescent and star are bright golden yellow. If the crescent is white, you are looking at Maldives, Pakistan, or Turkey; if it is golden yellow, it points directly to Mauritania.
4. 4Beware Outdated 1959 Graphics: Some older trivia platforms still display the pre-2017 Mauritanian flag without red bars. On PicRush, the official sovereign ensign features the modern statutory red stripes adopted in 2017.
5. 5Associate with Sahelian Desert Vigilance: Connect the colors: Green for the Islamic faith, Gold for the Sahara sand dunes, and Red for the martyrs guarding the desert frontiers.
