The Laos anthem was composed in 1941 and was first used when the Kingdom of Laos was created in 1947. Despite the original lyrics (sheet music with Lao lyrics (Lao and Latin scripts)) lacking references to the royal family, the lyrics were changed after the 1975 communist revolution that deposed the royal family; the melody, however, was retained.
Special thanks to: Jo Hyo-roe for the sheet music.
