On April 13, 1204, Constantinople fell to the Crusaders, where they established the Latin Empire. According to medieval sources, newly incorporated territories were given to Alexios and David Komnenos, where they founded a pro-Georgian state, the Empire of Trebizond. Alexios was proclaimed emperor, while David was appointed strategos. Some scholars believe that the new state was subject to Georgia, at least in the first years of its existence, at the beginning of the 13th century.
