David II of Trebizond was the final ruler of the Empire of Trebizond, holding the throne from 1460 until its fall in 1461. Born around 1408 in Trabzon to Alexios IV and Theodora, he previously held the title of despotes. His brief reign ended when he surrendered the empire to Mehmed II in August 1461. After his defeat, he was eventually executed in Constantinople in late 1463.
