Farewell of Slavianka, written by Vasily Agapkin premiered in 1912, was written for the woman of Bulgaria when they accompanied their husbands in the First Balkan War.
A theory of where the melodies originated is that it was inspired by the Russian march "Yearning for the Motherland" or that it originated from an old folk anti-war song during the Russo-Japanese War.
The melody gained it's popularity in Russia and other adjoining countries during WWI when the men left their homes to this music. Also, it was preformed on November 7, 1941 on Red Square where the soldiers left straight to fight in the Battle of Moscow.
Встань за Веру, Русская Земля!
Arise, Russian Land, defend your Faith!
This piece was later transcribed with no voice, just band, in the late 1990's.
Original sang by the Russian Red Army
