The Sahrawi Arab Democratic Republic, commonly known as Western Sahara, uses a national flag consisting of a black, white and green horizontal tricolor charged with a red star and crescent in the center stripe and a red chevron at the hoist. It is used on Polisario-controlled areas, while the Moroccan flag is used on the rest of the occupied territory.
The flag is a combination of the Pan-Arab colors of black, green, white, and red, and the Islamic symbol of the star and crescent. On 27 February 1976 the flag was adopted as the official flag of the Sahrawi Arab Democratic Republic (SADR). It was slightly modified in June 1991. It is said to be designed by El Uali Mustapha Sayed, the first president of the SADR. This flag is commonly referred to as the "flag of Western Sahara".
