David Megas Komnenos was the last Emperor of Trebizond from 1460 to 1461. He was the third son of Emperor Alexios IV of Trebizond and Theodora Kantakouzene. Following the fall of Trebizond to the Ottoman Empire, he was taken captive with his family to the Ottoman capital, Constantinople, where he and his sons and nephew were executed in 1463.
The Empire of Trebizond, or Trapezuntine Empire, was a monarchy and one of three successor rump states of the Byzantine Empire, along with the Despotate of the Morea and the Principality of Theodoro, that flourished during the 13th through to the 15th century, consisting of the far northeastern corner of Anatolia and the southern Crimea. The empire was formed in 1204 with the help of the Georgian queen Tamar after the Georgian expedition in Chaldia and Paphlagonia, commanded by Alexios Komnenos a few weeks before the sack of Constantinople. Alexios later declared himself Emperor and established himself in Trebizond. Alexios and David Komnenos, grandsons and last male descendants of deposed Emperor Andronikos I Komnenos, pressed their claims as "Roman emperors" against Byzantine Emperor Alexios V Doukas. The later Byzantine emperors, as well as Byzantine authors, such as George Pachymeres, Nicephorus Gregoras and to some extent Trapezuntines such as John Lazaropoulos and Basilios Bessarion, regarded the emperors of Trebizond as the "princes of the Lazes", while the possession of these "princes" was also called Lazica. Thus from the point of view of the Byzantine writers connected with the Laskaris and later with the Palaiologos dynasties, the rulers of Trebizond were not emperors.

Alexios I Megas Komnenos or Alexius I Megas Comnenus was, with his brother David, the founder of the Empire of Trebizond and its ruler from 1204 until his death in 1222. The two brothers were the only male descendants of the Byzantine Emperor Andronikos I, who had been dethroned and killed in 1185, and thus claimed to represent the legitimate government of the Empire following the conquest of Constantinople by the Fourth Crusade in 1204. Although his rivals governing the Nicaean Empire succeeded in becoming the de facto successors, and rendered his dynastic claims to the imperial throne moot, Alexios' descendants continued to emphasize both their heritage and connection to the Komnenian dynasty by later referring to themselves as Megas Komnenos.
The House of Kantakouzenos, Latinized as Cantacuzenus and anglicized as Cantacuzene, was one of the most prominent Greek noble families of the Byzantine Empire in the last centuries of its existence. The family was one of the Empire's wealthiest and provided several prominent governors and generals, as well as two Byzantine emperors. The Kantakouzenoi intermarried extensively with other Byzantine noble families such as the Palaiologoi, the Philanthropenoi, the Asen, and the Tarchaneiotes. The feminine form of the name is Kantakouzene, Latinized as Cantacuzena.
