Duke of Aquitaine and Count of Poitou

William was the son and successor of William IV, Duke of Aquitaine and Emmaline of Blois, born in 969. (She has an unknown burial I will not to.) Grandson of William III, Duke of Aquitaine his wife, Adele, Theobald I of Blois and Lutgarde of Vermandois.

William was the husband of Adalemode of Limoges, the widow of Adalbert I of La Marche. They had one son:
* William VI, his successor

Secondly, he was the husband of Sancha of Gascony, the daughter of Duke William II Sanchez of Gascony and his wife, the sister of Sancho VI William. They had two sons and one daughter:
* Odo, a duke
* Adalais, wife of Count Guiraut Trancaleon of Armagnac
* Theobald, died young
Sancha died by 1018.

Thirdly, he married Agnes of Burgundy, the daughter of Otto-William, Duke of Burgundy. They had two sons and a daughter:
* Peter William, Duke William VII
* Guy Geoffrey, Duke William VIII
* Agnes, wife of Henry III, the Holy Roman Emperor

William became Duke of Aquitaine in 990, his father died in 994, and his mother remained regent of Aquitaine until 1004. She was known to be quite formidable and ruled with strength. William was well educated and a book collector, as well as a friend of Bishop Fulbert of Chartres, a prominent teacher. William made the court of Aquitaine the largest learning center in Southern France.

William was no an expert in the field, and was defeated by Boso of La Marche despite assistance from his suzerain, Robert II of France. William was also defeated by the Vikings in 1006 who attacked his coast annually, and lost the Loudunais and Mirebalais to Fulk Nerra, count of Anjou, as well as Confolens, Ruffec, and Chabanais in order to compensate William II of Angoulême.

He was successful through his patronization of the Peace and Truce of God movements initiated by Pope and Church to bring some peace to his highly feudal territories. He founded Maillezais Abbey in 1010 and Bourgueil Abbey, rebuilt the cathedral and many other religious structures in Poitiers after a fire. He traveled widely in Europe, annually visiting Rome or Spain as a pilgrim.

William was approached by the Italians to help rule Italy when their own Henry II died, and six of William's letters involving the proposals survived the decades. William died peacefully as was his realm, on the first or second of January at Maillezais, where he is buried.
