John of Randazzo

John of Randazzo (1317–1348) was the fourth son of Frederick III of Sicily and Eleanor of Anjou, and the most powerful nobleman in Sicily under his brother Peter II and his nephew Louis. In 1338 he received the duchy of Randazzo, and he also held the duchies of Athens and Neopatria and the county of Malta.

When Peter II died in 1342, John became regent for the young Louis. He favoured the Catalan party over the local Italian nobility, yet kept the kingdom at peace, and named the Catalan Blasco II de Alagona to succeed him.

He married Cesarea, daughter of the count of Castalnasetta, and their son Frederick became Duke of Athens after him. John died of the Black Death in 1348 and was buried beside his father and nephew in Catania cathedral. War broke out upon his death.
