Bulgaria: National Flag
“Mila Rodino” (Bulgarian: Мила Родино, [ˈmiɫɐ ˈrɔdino]; lit. ’Dear Motherland’) is the national anthem of Bulgaria. It was composed and written by Tsvetan Radoslavov as he left to fight in the Serbo-Bulgarian War in 1885. The anthem was adopted in 1964. The text has been changed many times, most recently in 1990. On 12 July 1991 the anthem was shortened to its first verse along with the chorus.
Between 1886 and 1947, the Bulgarian national anthem was “Shumi Maritsa”; from 1951 to 1964, it was “Balgariyo mila, zemya na geroi”; in the brief period between these two, it was the march “Republiko nasha, zdravey!”.
