In 879 the German king Louis the Younger, encouraged by the Bishop of Paris, had invaded West Francia, reaching as far as Verdun, but retreated after his nephews, King Louis II of France and Carloman III of France had given their share of Lotharingia (Lorraine) to him. The Treaty of Ribemont confirmed Louis the Younger’s possession of Lotharingia, in exchange for his neutrality. The peaceful settlement was not destined to last. In 887 Arnulf, duke of Carinthia, overthrew his uncle Charles the Fat to become king of East Francia. Odo of France was elected king of West Francia from 888–898.
