Bulgaria

The flag of Bulgaria (Bulgarian: знаме на България, zname na Balgariya) is a tricolour consisting of three equal-sized horizontal bands of (from top to bottom) white, green, and red. White represents peace, green represents the fertility of the Bulgarian lands, and red stands for the courage of the people.

Some early versions of the flag (such as the Samara flag) used the Pan-Slavic colours, which were derived from the Pan-Slavism of 19th-century Europe. [More info]
