Flag of Algeria

The flag of Algeria is composed of two equal vertical stripes of green and white, with the green portion positioned at the hoist. Positioned in the center of the field is a red five-pointed star partially enclosed by a red crescent. This design is set within a rectangular frame featuring an aspect ratio of 2:3.

Green represents the Islamic faith, while white signifies the concept of purity and the peace achieved after conflict. Red is used for the star and crescent to commemorate the blood of those who died fighting for liberation. These celestial symbols together denote the nation's religious identity and its historical connections to the wider Muslim world.

Official adoption occurred on July 3, 1962, following the country's successful struggle for independence from France. Historians often attribute the design to Émilie Busquant, the wife of nationalist leader Messali Hadj, who likely created the first version in the 1930s. Prior to this, the National Liberation Front (FLN) utilized the banner as a revolutionary symbol throughout the 1950s. Earlier regional flags included the white standard of Emir Abdelkader used during the 19th-century resistance.
