"Chant de Ralliement" or "The Rallying Song" is the national anthem of Cameroon. It was used on an unofficial basis beginning in 1948 before independence, and officially adopted in 1957. The music was composed by René Djam Afame, who also wrote the lyrics along with Samuel Minkio Bamba and Moïse Nyatte Nko'o. The lyrics were changed in 1978.
