Andronikos II of Trebizond

Andronikos II Megas Komnenos, or Andronicus II Megas Comnenus, was the Emperor of Trebizond from 1263 to 1266. Despite being the designated successor of his father Manuel I, Andronikos' tenure was short due to premature death from unrecorded causes. The major event of his reign was the definitive loss of Sinope to the Seljuk Turks under the regency of Mu‘in al-Din Suleyman, also known as the Pervane, in the summer or fall of 1265. The capture of Sinope by the Turks gave them the best port on the Black Sea, allowing them to create a navy and compete with the Trapezuntines for influence in the Black Sea.
