Question

Why and how the National Anthem of France was composed​

Answer 1

After France declared war on Austria on April 20, 1792, P.F. Dietrich, the mayor of Strasbourg (where Rouget de Lisle was then quartered), expressed the need for a marching song for the French troops. “La Marseillaise” was Rouget de Lisle’s response to this call. Originally entitled “Chant de guerre de l’armée du Rhin” (“War Song of the Army of the Rhine”), the anthem came to be called “La Marseillaise” because of its popularity with volunteer army units from Marseille. The spirited and majestic song made an intense impression whenever it was sung at Revolutionary public occasions. The Convention accepted it as the French national anthem in a decree passed on July 14, 1795.
