John Synadenos

John Komnenos Angelos Doukas Synadenos was a Byzantine noble who held the rank of megas stratopedarches under Michael VIII and Andronikos II. First attested in 1276/77, he and Michael Kaballarios led an army against the independent ruler of Thessaly, John I Doukas.

Routed at Pharsalus, Synadenos was captured while Kaballarios was killed attempting to escape; Synadenos later regained his freedom. He fought in the victory over the Angevins at Berat in 1281 and campaigned against Thessaly again in 1283. He ended his life as the monk Joachim, dying between 1310 and 1328, and left children by Theodora Palaiologina, niece of Michael VIII.
