People's Republic of the Congo National Anthem (1970–1991; Instrumental) Les Trois Glorieuses

The People's Republic of the Congo (French: République populaire du Congo) was a Marxist–Leninist one-party socialist state that was established in 1969 in the Republic of the Congo. Led by the Congolese Party of Labour (French: Parti congolais du travail, PCT), it existed until 1991 when, following the dissolution of the Soviet Union, the country's earlier name was restored.

Les Trois Glorieuses was the anthem of the People's Republic of the Congo from January 1, 1970 through 1991, when the original anthem, La Congolaise was restored.
The anthem was named after a three-day uprising in 1963 which resulted in the overthrow of the first President, Fulbert Youlou.
