Principality of Theodoro
In ca. 1223, the towns of Gothia may have been tributary to the Empire of Trebizond, and in the late 13th/early 14th century Mangup became the centre of the Principality of Theodoro, whose ruling elite maintained Byzantine traditions and the use of the Greek language. The ruling dynasty, stemming from the area of Trebizond, was called "Gabras" (in Greek) or "Chowra" (in Turkish). In the late 14th century, one branch of the dynasty emigrated to Moscow, where they established the Simonov Monastery. The Khovrins, as they came to be known, were hereditary treasurers of Muscovy. In the 16th century, they changed their name to Golovin.
