The siege of Trebizond was the successful siege of the city of Trebizond, capital of the Empire of Trebizond, by the Ottomans under Sultan Mehmed II, which ended on 15 August 1461. The siege culminated a lengthy campaign on the Ottoman side, which involved coordinated but independent manoeuvres by a large army and navy. The Trapezuntine defenders had relied on a network of alliances, which would provide them with support and a workforce when the Ottomans began their siege. Still, it failed when Emperor David Megas Komnenos most needed it. The Ottoman land campaign, which was the more challenging part, involved intimidating the ruler of Sinope into surrendering his realm, a march lasting more than a month through uninhabited mountainous wilderness, several minor battles with different opponents and finally the siege of Trebizond. The combined Ottoman forces blockaded the fortified city by land and sea until Emperor David agreed to surrender his capital city on terms. In return for his tiny realm, he would be given properties elsewhere in the Ottoman Empire, where he, his family, and his courtiers would live until their execution some two years later.
