"Mila Rodino" (Bulgarian: Мила Родино, [ˈmiɫɐ ˈrɔdino]; "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.
