Manfred of Athens

Manfred (1306–1317) was the second son of Frederick III of Sicily and Eleanor of Anjou, born at Catania. After the Catalan Company defeated Walter V of Brienne and conquered Athens in 1311, it offered the duchy to King Frederick, who in 1312 invested the young Manfred as duke instead, sending a regent to govern in his name.

Manfred never visited his duchy. In November 1317, aged about eleven, he died after a fall from a horse at Trapani. Athens then passed to his younger brother William.
