Note	BIOGRAPHY Guillaume V-VII was born Pierre-Guillaume about 1023. Called Guillaume 'Aigret' ('the Eagle') of 'le Hardi' ('the Bold'), he was the duke of Aquitaine and count of Poitou between 1039 and his death. Guillaume was the fourth son of Guillaume III-V 'le Grand', duc d'Aquitaine, comte de Poitou, by his third wife, Agnes de Bourgogne. He was brother-in-law of the Holy Roman Emperor Heinrich III, who married his sister Agnès de Poitou. His mother was remarried to Geoffrey II Martel, comte d'Anjou, during his reign. Before 1041 Guillaume married Ermesinde de Longwy, of unknown origins, and had two daughters, both of whom would have progeny: Clémence who married Konrad I, Graf von Luxemburg, and Agnes who married Peter, count of Savoy. Guillaume won his patrimony in a war with his half-brother Eudes, who was killed in battle at Mauzé on 10 March 1039. Guillaume did not, however, succeed in occupying Gascony. Geoffrey II Martel refused to concede to him the territories gained in the reigns of his predecessors. Guillaume set to work regaining his patrimony by force of arms. He was besieging Geoffrey in Saumur when he died of dysentery in the autumn of 1058. He was succeeded by his brother Guy-Geoffriou, who would rule as Guillaume VI-VIII.

BIOGRAPHY
Guillaume V-VII was born Pierre-Guillaume about 1023. Called Guillaume 'Aigret' ('the Eagle') of 'le Hardi' ('the Bold'), he was the duke of Aquitaine and count of Poitou between 1039 and his death.

Guillaume was the fourth son of Guillaume III-V 'le Grand', duc d'Aquitaine, comte de Poitou, by his third wife, Agnes de Bourgogne. He was brother-in-law of the Holy Roman Emperor Heinrich III, who married his sister Agnès de Poitou. His mother was remarried to Geoffrey II Martel, comte d'Anjou, during his reign.

Before 1041 Guillaume married Ermesinde de Longwy, of unknown origins, and had two daughters, both of whom would have progeny: Clémence who married Konrad I, Graf von Luxemburg, and Agnes who married Peter, count of Savoy.

Guillaume won his patrimony in a war with his half-brother Eudes, who was killed in battle at Mauzé on 10 March 1039. Guillaume did not, however, succeed in occupying Gascony. Geoffrey II Martel refused to concede to him the territories gained in the reigns of his predecessors. Guillaume set to work regaining his patrimony by force of arms. He was besieging Geoffrey in Saumur when he died of dysentery in the autumn of 1058. He was succeeded by his brother Guy-Geoffriou, who would rule as Guillaume VI-VIII.
