A palace official in Benin has announced the death of the King of Abomey, Kêfa Sagbadjou Glèlè.
His predecessors ruled Dahomey, which was one of the most powerful kingdoms in West Africa before the colonial era.
The king was reported to have been in his nineties, though his exact age has not been confirmed.
He was last seen in public in November at a ceremony to mark the return by France of 26 royal treasures stolen by French troops in the 19th Century.
