- William IV of Aquitaine
William IV (937 –
3 February 994 ["Nouvelle Biographie Générale". The date of5 February 995 probably comes from Owen.] ), called Fierebras or Fierebrace (meaning "Iron Arm", from the French "Fier-à-bras" or "Fièrebrace", in turn from the Latin "Ferox brachium"), was theDuke of Aquitaine andCount of Poitou from 963 to his retirement in 990.William's father, William III, abdicated to the abbey of
Saint-Cyprien inPoitiers and left the government to Fierebras. His mother wasGerloc , the daughter of DukeRollo of Normandy . His sister was Adelaide, wife ofHugh Capet , the king against whom William later battled for his duchy. His early reign was characterised by many wars. He fought frequently against thecounts of Anjou , the first time against Geoffrey Greymantle, who had takenLoudun .In 988, he went to war with the newly-elected
king of France , Hugh Capet, whom he refused to recognise. Capet had been granted Aquitaine by King Lothair before the latter had been reconciled to William's father. Capet renewed his claim on the great duchy and invaded it that year. A royal army was defeated on the plain of theLoire Valley . William sheltered the young Louis, the son ofCharles, Duke of Lower Lorraine , the last legitimateCarolingian heir. He opened thepalace of Poitiers to him and treated him as royalty, regarding him as the true heir to the French throne.In 968, he married Emma or Emmeline, daughter of
Theobald I of Blois andLuitgarde of Vermandois . Their marriage was stormy, in part because of William's indulgence in the pursuit of women and, a hunting aficionado, wild animals. She banished his paramours, they separated twice for long periods, and finally he retired to a monastery, as his father had done, leaving Emma to rule Aquitaine in the name of their son William until 1004. Their second son, Ebles, died sometime after 997.Notes
