Carlo I Tocco
The war in Morea had started to go against the Byzantines and, under pressure from Carlo I Tocco, the Count of Kefalonia and ruler of Epirus, the Despot demanded help from his brother John VIII. That help came in the form of reinforcements led by their brother Constantine, who became joint governor of Morea with Theodore II in 1428. The united efforts of the brothers contributed to the naval victory at the Echinades in 1427 and the conquest of Patras in 1430.
