Richard Orsini
Richard Orsini (Italian Riccardo, died 1303/1304) ruled as count palatine of Cephalonia and Zakynthos from before 1260. Around 1262, while he was still a minor, William II of Villehardouin acted as regent.
As an Angevin vassal he served as captain-general of Corfu and as bailli of the Principality of Achaea in 1297–1300. In 1291/1292 he aided Despot Nikephoros I of Epirus against the Byzantine forces besieging Ioannina, and married his heir John I to the despot's daughter Maria without consulting her father, paving the way for the Orsini takeover of Epirus. He was accidentally killed by one of his own knights.
