In 1289 he abandoned the barony and returned it to the domain in exchange for the fortress of Beauvoir (which he soon after exchanged again with John Chauderon for lands in Italy). The barony was then reconstituted in its entirety and granted by King Charles II of Naples to Isabella of Villehardouin and her husband Florent of Hainaut, at the occasion of their confirmation as Princess and Prince of Achaea. In 1303, Isabella granted the fortresses of Karytaina and Araklovon (Fr. "Bucelet") to her infant daughter Margaret of Savoy, who renounced her claims in Achaea upon her marriage in 1324. In 1320, Karytaina and the eastern half of the ancient barony fell into the hands of the Byzantines under Andronikos Asen. Five years later, Prince John of Gravina tried to recover the fortress, but without success. Along with the Barony of Damala, Karytaina is the sole barony of Achaea known to have minted coinage in its own name: a series of billon deniers issued in the 1290s by Helena Angelina Komnene, second wife and widow of Hugh of Brienne. These were marked with the legends "HELENA D[E]I GRA[TIA]" and "CLARICTIA S[EMI] F[EUDI DOMINA]", apparently in claim of her husband's half-barony. As A. Bon points out, however, this issue was struck with CLARICTIA and not CARITENA, and at any rate was made in her capacity as regent for the Duchy of Athens rather than as lady of Karytaina.
