Indonesia Raya Merdeka! Merdeka!

The song was first introduced by composer, Wage Rudolf Soepratman, on October 28, 1928 at the Kongres Pemuda II  in Batavia. The first stanza of Indonesia Raya selected as the national anthem when Indonesia proclaimed its independence on August 17, 1945. Indonesia Raya is played in flag ceremonies. Indonesian flag raised solemnly and movements are arranged so that the flag reached the top of the flag pole when the song ends. Flag ceremony is held every year on August 17 to commemorate Indonesia's independence day.
After echoed in 1928 in front of the Kongres Pemuda participants with violin II, the Dutch East Indies colonial government immediately ban the mention of the national anthem, Indonesia Raya. Even so, the young man did not trembling. They sang the song by saying "Mulia! Mulia!" (instead of "Merdeka, Merdeka!") on the chorus. Furthermore, Indonesia Raya song always sung at every meeting of political parties. After Indonesian independence, the song was set as a symbol of the unity of the nation's national anthem.
