The national flag of Algeria 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.
Red, Green, White
Algeria has repeatedly used crescent moons in its national flag (a symbol of Islam). These flags were first flown by Algerian pirates in the 15th century.
Algeria has specific laws about its national flag. Regulations include that the color green must be equal parts yellow and blue and the red must be "pure", not containing any blue or yellow tones.
