When his brother-in-law Bouchard III died, he inherited Vendôme.
He took part in the war between the brothers, the counts of Anjou, Geoffrey III and Fulk IV.
He originally supported Fulk, but reversed his allegiance and was imprisoned by Lancelin de Beaugency only to be released in 1090 with a ransom.
He followed his predecessors into conflict with the Trinity Abbey, Vendôme and was excommunicated.
With his wife, Euphrosine, sister of Bouchard IV, he had three sons: Geoffrey had donated a church to the abbey of La Trinité of Vendôme which Euphrosyne took back after his death.
