Wallis and Futuna

 

An overseas collectivity of France in the south Pacific (essentially an autonomous territory of France but not an integral part of the country), “La Marseillaise” is used as the national anthem, and while there does not appear to be any local anthem for the collectivity as a whole, there are three traditional kingdoms that cover the islands and are ruled by local tribal kings, and these could have royal anthems.

Special thanks to: John D. McMeekin for information on the existence of the tribal kingdoms.
