The surrender of the Empire of Trebizond to the forces of Sultan Mehmed II represents a pivotal moment in the decline of the Byzantine Empire and the consolidation of Ottoman power. The siege that led to this surrender began in 1461, as Mehmed sought to eliminate the remaining vestiges of Byzantine rule along the Black Sea. Trebizond, which had been an important cultural and trading hub, was the final remnant of the once vast Byzantine Empire. The Empire of Trebizond had maintained a degree of autonomy but was increasingly vulnerable to Ottoman advances. After a protracted siege, the city fell when its defenses proved insufficient against the well-coordinated Ottoman military strategy.Following the fall, Emperor David Komnenos was captured. His fate took a dark turn as he was exiled, reflecting the common practice of disposing of rulers who could potentially rally opposition. Reports indicate that David was ultimately murdered, illustrating the ruthless nature of political consolidation during this period. The fall and subsequent events symbolized not merely the loss of a city but the definitive close of Byzantine rule, as Trebizond was the last imperial city outside of Constantinople still under Byzantine control. This marked a significant territorial gain for the Ottomans and the final chapter of Byzantine sovereignty.
