"Tiến Quân Ca" (lit. "The Song of the Marching Troops") is the national anthem of Vietnam. The march was written and composed by Văn Cao in 1944, and was adopted as the national anthem of North Vietnam in 1946 (as per the 1946 constitution) and subsequently the Socialist Republic of Vietnam in 1976 following the reunification of Vietnam. Though it has two verses, only the first one is usually sung.
