In 1214, on this day forces loyal to Trapezuntian emperor Alexios I (pictured) lifted the Siege of Sinope.
Komnenos Brothers lift the Siege of SinopeThe Seljuq Turks under their Sultan, Kaykaus I Sinope had attempted to seize this important port city on the Black Sea coast of modern Turkey, at the time held by the Empire of Trebizond, one of the Byzantine Greek successor states formed after the Fourth Crusade.
The hard fought victory was in no part due to the individual heroics of David Komnenos , Alexios' younger brother and co-founder of the Trapezuntian empire. Because much was at stake; defeat would have meant that the small Trapezuntian state would be cut off from overland contact with the metropolitan Byzantine lands of the Empire of Nicaea in western Asia Minor.
But instead, Alexios was given a legitimate claim to be Byzantine emperor (he was the eldest son of Manuel Komnenos and of Rusudan, daughter of George III of Georgia and thus a grandson of the Byzantine Emperor Andronikos I). Because in April 1204, shortly before the fall of Constantinople to the Fourth Crusade, the 22-year-old Alexios had occupied Trebizond with the aid of a Georgian contingent provided by his aunt, Queen Tamar of Georgia. Ten years later, he was all set for a triumphant return.
