The national flag of Burundi was adopted on March 28, 1967. It consists of a white saltire which divides the field into alternating red and green areas.
The center of the saltire merges into a white disk, on which there are three red solid six-pointed stars outlined in green. The ratio of the flag was 2:3 until September 27, 1982.
The green colour symbolizes hope, the white symbolises peace, and red those who fell in the struggle for independence. The three stars stand for the three major ethnic groups of Burundi: the Hutu, the Twa and the Tutsi. The three stars also stand for the three elements of the national motto: Unité, Travail, Progrès (“Unity, Work, Progress”), which can be seen on the Coat of arms of Burundi. Wikipedia
