[1] He was, like his father, a vassal of his uncle Hugh the Great.
After the death of Hugh the Great, Hugh II allied with Fulk II the Good, Count of Anjou, and Theobald the Trickster, Count of Blois.
Hugh later joined Theobald’s son Odo against Seinfroy, Bishop of Le Mans.
Hugh and Odo had to flee and seek refuge with Bouchard I, Count of Vendôme, in the areas that form the Bas-Vendômois.
In 939 he fought alongside Alan II, Duke of Brittany and Judicael Berengar against the Vikings at the Battle of Trans-la-Forêt.
