Andronikos I Gidos
Andronikos I Gidos (died 1235) ruled the Empire of Trebizond from 1222, the only emperor unrelated by blood to its founder Alexios I, whose daughter he married.
After a Seljuk raid on Trapezuntine territory, Andronikos sent a fleet against Sinope. In 1224 he led the defense of Trebizond against a Seljuk siege until a storm scattered the attackers; the captured sultan agreed to end Trebizond's vassalage, tribute and military obligations.
After Andronikos backed the Khwarazmshah Jalal al-Din against the Seljuks in 1230, Trebizond became a vassal once more. He died in 1235 and John I succeeded him.
