"The National Flag of Algeria features two equal vertical bands of green (hoist side) and white. A red, five-pointed star within a red crescent is centered over the boundary of the two colors. The green color represents Islam, which is the dominant religion in the region. Green is also said to have been the favorite color of the Prophet Muhammad and his daughter Fatima and is the color of paradise in the Quran. The red color symbolizes freedom and the blood that was shed to attain liberty at the hands of the French in the struggle for independence. The white color represents the purity and peace that was attained after independence. The crescent and the star are also the traditional symbols of Islam, but the crescent is more closed than those of other Muslim countries because the Algerians believe that the long crescent horns bring happiness."
