John of Gravina

John of Gravina (1294–1336), youngest son of Charles II of Naples, was a prince of the Capetian House of Anjou. In 1315 he succeeded his brother Peter, killed at Montecatini, as Count of Gravina. In 1318 his brother Philip I of Taranto forced Matilda of Hainaut to marry him; when she refused to surrender her rights and secretly married Hugh de La Palice, Philip stripped her of Achaea, gave it to John, and annulled the marriage.

His 1325 Morea expedition failed to retake Skorta from Byzantium, and in 1332, unwilling to swear fealty to his nephew Robert of Taranto, he exchanged Achaea for claims to Albania and ruled as Duke of Durazzo until his death in April 1336.
