Charles II succeeded his father, Charles I, in Achaea as well as Sicily (now reduced to the Kingdom of Naples), but he was a prisoner in Aragonese hands. In the interim, the rule of Achaea devolved upon a series of baillis chosen from the Morean nobility. Not long after his release and coronation in 1289, he granted the Principality to Isabelle of Villehardouin upon her marriage with Florent of Hainaut, in part to redress the greedy application of the Treaty of Viterbo at William's death. However, he retained feudal overlordship over the Principality, and his grant provided that neither Isabelle nor any daughter who was her heir might marry without his consent. |  |
