For this period the principality was under a violent succession dispute, which originated from the dispossessed Latin Emperor Baldwin II's gift of the overlordship of Achaea to Charles I of Sicily in return for support in his attempt to reconquer the throne in Constantinople, an action which ignored the rights of the Villehardouin Princes of Achaea. The Angevin kings of Naples subsequently gave Achaea as their fief to a series of their own relatives and creatures, who fought against Princess Margaret of Villehardouin and her heirs.
