The national flag of Algeria ( Arabic: علم الجزائر, romanized: ʿalam al-jazāʾir, Berber languages: ⴰⵛⴻⵏⵢⴰⵍ ⵏ ⴷⵣⴰⵢⴻⵔ, romanized: Acenyal n Dzayer ) consists of two equal vertical bars, green and white, charged in the center with a red star and crescent, a symbol of Islam as the nation’s prominent faith. The flag was adopted on 3 July 1962. A similar version was used by the Algerian government in exile from 1958 to 1962. The Western blazon is per pale vert and argent; a crescent and star gules.
The Barbary pirates of Ottoman Algeria between the 15th and 17th century widely used flags that were emblazoned with one or more crescents. These could however vary greatly in color, with dark red, black, green and white being in use. Besides these, Algerian pirates also used various flags in plain color, such as plain black ones signalling death. Less often, Algerian flags of this time also carried other motifs, such as suns, stars and crossed swords. It is also known that city of Algiers used an orange flag with a white horizontal sword on it by the early 19th century.
Émilie Busquant is perhaps best known as the creator of the current Algerian flag. While there is some dispute over who exactly designed green and white with red star and crescent symbol, Busquant is generally credited as having sewed the first version of the flag in 1934.
