What is the national anthem of France?
List of historical national anthems
An anthem may fall out of use if the country that uses it ceases to exist, or because it adopts a new anthem; the rationale for a new national anthem is often political, perhaps based on a new ruling dynasty or system of government. For example, following the French Revolution, which overthrew the monarchy, "La Marseillaise", a republican revolutionary song, became France's national anthem in 1795. Conversely, when the monarchy was restored 19 years later, the 16th-century royalist tune "Vive Henri IV" was revived and adapted to create "Le Retour des Princes français à Paris", an overt celebration of the restored government. Following a number of further changes, "La Marseillaise" was readopted in 1870 and remains France's contemporary national anthem. Similar changes have occurred when Libya, Iraq, and South Africa democratized in the 2010s, 2000s, and 1990s respectively, new national anthems were adopted for those countries as well.
La Congolaise
"La Congolaise" () 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.
