Congo: National Flag
“La Congolaise” (English: “The Congolese”, Kongo: “Besi Kôngo”) is the national anthem of the Republic of the Congo. It was adopted upon independence from France in 1959, replaced in 1969 by “Les Trois Glorieuses” but reinstated in 1991. The lyrics were written by Jacques Tondra and Georges Kibanghi, and the music was composed by Jean Royer and Joseph Spadilière.
