The flag of Mauritania is the common name for the national flag of Mauritania in north-west Africa. The flag was adopted on April 1, 1959. It was introduced under the instructions of Moktar Ould Daddah and the subsequent constitution of 22 March 1959.
The colors of green and gold are considered Pan-African colors. Green is also used to symbolize Islam, and the gold for the sands of the Sahara desert. The crescent and star are symbols of Islam, which is the major religion in the nation. Some writers have also speculated that green symbolises a bright future, and growth.
