Flag of Bulgaria

The three national colours – white, green and red – are linked to those used by the Old Bulgarian Army. The left wing of the army was distinguished by white strips on its spears, the right being marked with red ones. The elite troops, arranged in the middle, had a green strip, which was the traditional colour of the ruler at the time. The three-coloured flag had first been used by the First Bulgarian Legion of Georgi Rakovski (1861) and then confirmed as Bulgaria’s national flag in the Turnovo Constitution (1879).
