Despotate of the Morea
In the Middle Ages it was called Arkadía, a name which was transferred from the interior of the peninsula to this place upon the coast. Under the Principality of Achaea, Kyparissia/Arkadia was the seat of the Barony of Arcadia, which was the last Frankish territory (except for the Venetian possessions) to fall to the Despotate of the Morea, in 1432.
