Hugh the Great, d. 956, French duke; son of King
Robert I and father of
Hugh Capet. Excluded from the succession on his father's death by his brother-in-law
Raoul, he supported the candidacy of
Louis IV, the Carolingian heir, after Raoul's death (936). Hugh hoped to rule through this weak king who had been raised in England. Louis IV attempted to increase his strength, however, and his reign was marked by warfare between king and vassal, in which Hugh, excommunicated (948) at the insistence of Louis, was forced to submit (950). Although Hugh never held the title of king, his vast possessions made him the virtual ruler of France.
