Empire of Trebizond
The Empire of Trebizond, or Trapezuntine Empire, was a monarchy and one of three successor rump states of the Byzantine Empire 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.
