The so called, ‘Trapezund Empire’ was founded in 1204, as a buffer zone among Georgia, Byzantine and newly appeared Seljuk states. The Georgian influence remained significant over the Trapezund till the very last days of its existence.

During the existence of Trapezund Empire some famous historical sources were created. Among them it can be mentioned Mikhail Panaretos’s ‘Trapezund Chronicle’.  It describes the events which took place in Trapezund, Near East and neighboring countries from 13^-th to 15^-th century.

The first point of Chronicle which deserves our interest, is dated to 1336 and is concerned with the unknown invader, ‘Sheikh Hasan, Son of Tamarta’’. According to our investigation, he can be identified as Sheik Hasan, son of Timurtash. Sheik Hasan was the grandson of famous Mongolian noion (military commander) Choban, and he really had the son Timurtash and grandson Shaikh Hasan surnamed as ,,Kuchuk’’ (the ,,Smoller’’).

The second point of  "Trapezund Chronicle” helps us to identify the Turkish amir’s (ruler’s) name - ,,Khosia Baidaris-dze’’ who is mentioned in Ksani eristavs (governors) Family Chronicle so called ,,Dzegli Eristavta’’. We conclude that this invader, who ravaged South Georgia in the middle  of 14^-th century, could be Khajimir son of Bairam frequantly mentioned in Trapezund Chronicle  between 1357-1382 years.

The third moment reflected to the  "Trapezund Chronicle” is the visit of Trapezund’s king to Batumi in 1372. This is unique information about Batumi and its relations with Tapezund Empire. In spite of some foreign historians we are sure that Batumi and Gurieli’s land never had been in vassalage of Trapezund Emperor.
