Herbert I of Maine

Herbert I , called Wakedog or Evigilans Canis , was the count of Maine from 1015, the son and successor of Hugh III....

, one of the Hugonides.

He was a minor on the death of his father (1032/5). Herbert Baco, his great-uncle and a supporter of the Angevins, acted as regent.

The Bishop of Le Mans, Gervais du Château du Loir, was a partisan of the opposing Blois family. The bishop and regent clashed, with the outcome being the expulsion of Herbert by means of a popular council. Gervais then proclaimed Hugh to have reached his majority, and arranged a marriage for him, with Berthe de Blois.

Geoffrey Martel, Count of Anjou, struck back by invading Maine. From this point, the domain of Maine became a disordered place, with the Anjou and Blois parties joined by Norman interests in a struggle for control.
