William VIII of Montpellier

William VIII was Lord of Montpellier, the son of William VII and Matilda of Burgundy.
William VIII married Eudokia Komnene, grand-niece of the Byzantine emperor Manuel I Komnenos. They had one daughter, Marie of Montpellier.
Lacking a male heir, William separated from Eudokia, sending her to a monastery in Ariane.
William then married Agnes of Castile and sired eight more children:

Tortoseta
Bergunyo, a priest
Gui, a priest
Agnes, married in 1203 Raymond Roger Trencavel, viscount of Carcassonne, Béziers, Albi and Razès.
Adalaïs.

The Pope ruled William's marriage to Agnes as illegitimate and Marie was given the throne.
William VIII was a patron of troubadours. Arnaut de Mareuil came to his court after fleeing from the entourage of Azalais of Toulouse, and at least one of Arnaut's poems is addressed to him.
