Flag of Bulgaria

The flag of Bulgaria (Bulgarian: знаме на България, romanized: zname na Balgariya) is a tricolour consisting of three equal-sized horizontal bands of (from top to bottom) white, green, and red. The flag was first adopted after the 1877–1878 Russo-Turkish War, when Bulgaria gained independence. The national flag at times was charged with the state emblem, especially during the communist era. The current flag was re-established with the 1991 Constitution of Bulgaria and was confirmed in a 1998 law.
