In the second half of the 13th century, when the political integrity of
Georgia was broken and the state was divided into two kingdoms, Georgian influence in the
Empire of Trebizond began to decline, and pro-
Byzantine tendencies appeared in separate groups of the ruling circles of
Trebizond. This resulted in a struggle for political hegemony in the Empire of Trebizond between the Georgian and Byzantine parties that lasted for years. In 1281, a coup took place in Trebizond, organized by the Georgian party.
Emperor John II, who became the son-in-law of the royal house of the Byzantine
Palaiologos, was deposed from the throne and even captured. Then he was released from prison, but he was not allowed to stay in Trebizond, and the deposed king went to
Constantinople. ==Siege==
