William VII (born Peter, Pierre-Guillaume) (1023 – autumn 1058), called the Eagle 
(Aigret) or the Bold (le Hardi), was the duke of Aquitaine and count of Poitou (as 
William V) between 1039 and his death, following his half-brother Odo.

William was the third son of William V of Aquitaine, the eldest by his third wife, Agnes 
of Burgundy. He was brother-in-law of the Holy Roman Emperor Henry III, who married 
his sister Agnes. His mother remarried to Geoffrey Martel, Count of Anjou, during his 
reign. William won his patrimony in a war with his half-brother Odo, who was killed in 
battle at Mauzé. He did not, however, succeed in occupying Gascony.

Geoffrey Martel refused to concede to him the territories gained in the reigns of his 
predecessors. William set to work regaining his patrimony by force of arms. He was 
besieging Geoffrey in Saumur when he died of dysentery.

He was married to Ermesinde, of unknown origins. Two daughters have been 
hypothesized to be children of this couple:
Clementia, who married Conrad I of Luxembourg
Agnes, who married Peter I of Savoy.[1]
