The national flag of the Democratic Republic of the Congo is a sky blue flag, adorned with a yellow star in the upper left canton and cut diagonally by a red stripe with a yellow fimbriation. It was adopted on 18 February 2006. A new constitution, ratified in December 2005 and which came into effect in February 2006, promoted a return to a flag similar to that flown between 1966 and 1971, with a change from a royal blue to sky blue background. Blue represents peace. Red stands for "the blood of the country's martyrs", yellow the country's wealth; and the star symbol the future for the country.
During the period between 1971 and 1997 as Zaire, the flag consisted of a light green fabric with a yellow circle holding a flaming torch.
It is one of the few national flags incorporating a diagonal line, with other examples including Tanzania, Namibia, Trinidad and Tobago, Saint Kitts and Nevis, and Brunei.
