Charles the Bald (13 June 823 – 6 October 877) was the King of West Francia (843–77), King of Italy (875–77) and Holy Roman Emperor (875–77, as Charles II). After a series of civil wars that began during the reign of his father, Louis the Pious, Charles succeeded by the Treaty of Verdun (843) in acquiring the western third of the Carolingian Empire. He was a grandson of Charlemagne and the youngest son of Louis the Pious by his second wife, Judith.
