Mu isamaa on minu arm
"Mu isamaa on minu arm" is an Estonian poem by Lydia Koidula. The poem was first set to music for the first Estonian Song Festival in 1869 by Aleksander Kunileid.
"Mu isamaa on minu arm" became a popular patriotic song when a new melody was composed by Gustav Ernesaks in 1944. Beginning in 1947, it is always the last song performed at the Estonian Song Festival. During the Soviet regime, "Mu isamaa on minu arm" became an unofficial national anthem.
