BIOGRAPHY
Guillaume II-IV, called 'Fier-à-bras' ('Iron Arm'), was born about 935, the son of Guillaume I-III, duc d'Aquitaine, comte de Poitou and Gerloc (Adele) of Normandy. He was duke of Aquitaine and count of Poitou from 963 to his retirement in 990.

Guillaume's father retired to the abbey of Saint-Cyprien in Poitiers and left the government to his son. Guillaume's early reign was characterised by many wars. He fought frequently against the counts of Anjou, the first time against Geoffrey I 'Greymantle', comte d'Anjou, who had taken Loudun.

In 968 Guillaume married Emma de Blois, daughter of Thibaut I 'the Deceiver', comte de Blois et Chartres and Liutgarde de Vermandois. Their marriage was stormy, in part because of Guillaume's indulgence in the pursuit of women and, as a hunting aficionado, wild animals. She banished his paramours and they separated twice for long periods.

In 988 Guillaume went to war with the newly-elected king of France, Hugues Capet, whom he refused to recognise. Capet had been granted Aquitaine by King Lothar I before the latter had been reconciled to Guillaume's father. Capet renewed his claim on the great duchy and invaded it that year. A royal army was defeated on the plain of the Loire Valley. Guillaume sheltered the young Louis, the son of Charles, duc de Lorraine, the last legitimate Carolingian heir. He opened the palace of Poitiers to him and treated him as royalty, regarding him as the true heir to the French throne.

Like his father, Guillaume finally retired to an abbey, in his case the abbey of Saint-Maixent-L'Ecole, long associated with his family. He died there on 3 February 993. From his retirement his wife Emma ruled Aquitaine in the name of their son Guillaume until 1004. Their second son Ebalus died sometime after 997.
