Geoffrey was twice deprived of his barony, once for rebelling against his uncle, the Prince of Achaea William II of Villehardouin, and then for abandoning the Principality without leave in order to spend time with a mistress, the wife of one of his feudatories, in Italy. He was pardoned both times, but henceforth held his title as a gift of the Prince. He died childless in 1275, and the Barony of Karytaina was split up.

The bailli, bailie, or bailiff was the administrative representative of the Princes of Achaea, ruling the Principality of Achaea in the Prince's absence. The early princes, who belonged to the founding Villehardouin dynasty, resided in the principality, and governed it directly. In 1278, Achaea passed to Charles of Anjou, the King of Naples. Charles, and many of his successors, ruled the principality through their baillis, and never visited it in person. Originally, the baillis were Angevin officials, but the post was often given to powerful feudatories from Achaea and the rest of Frankish Greece.
