Carloman II

Carloman II (c. 866 – 6 December 884) was the King of West Francia (future France) from 879 until his death. A member of the Carolingians, he and his elder brother Louis III, divided the kingdom between themselves and ruled jointly until the latter's death in 882. Thereafter Carloman ruled alone until his own death. He was the second son of King Louis the Stammerer and Queen Ansgarde.
