Bulgaria, "Balgariyo Mila" (Dear Bulgaria) was the National anthem of Bulgaria in use from 1950-1964. The words were written by Nikola Furnadshiev, Mladen Issaev and Elisaveta Bagrjana and set to music by Georgi Zlatev-Tscherkin, Svetoslav Obretenov and Georgi Dimitri.
Once Communist rule was secured in Bulgaria, "Balgariyo mila" was introduced as the national anthem. Interestingly, the anthem was replaced in 1964 while the Communists were still in power. One of the composers of the music, Georgi Dimitrov (not to be confused with the Communist leader of the time with the same name) also wrote the previous anthem.
Georgi Dimitri (born June 18, 1882, Kovachevtsi, Bulg. — died July 2, 1949, near Moscow, Russia, U.S.S.R.) was a Bulgarian communist leader. He helped found the Bulgarian Communist Party in 1919. After leading a communist uprising in 1923 that provoked fierce government reprisals, he was forced to live abroad and became head of the central European section of the Com-intern in Berlin (1929 – 33). He won worldwide fame for his defense against Nazi accusations in the Reichstag fire trial of 1933. He headed the Comintern in Moscow (1935 – 43), then returned to Bulgaria, where he served as prime minister (1945 – 49). He effected the communist consolidation of power that formed the Bulgarian People's Republic in 1946.
