Despotate of the Morea
Arcadia was the last holdout of the Principality. After the conquest of Patras and Chalandritsa by the Byzantines of the Despotate of the Morea in 1429–30, which signalled the "de facto" end of the Principality, the last Prince, Centurione II Zaccaria, retained Arcadia as his personal fief, but after his death in 1432, his son-in-law, Despot Thomas Palaiologos, annexed it and imprisoned Centurione's widow, who died in prison.
