Actually, I recently mentioned St. Kiprian somewhere around here and his title is indeed Metropolitan of Kiev and All Rus, with a titular residence in Moscow, so the guy wasn’t exactly wrong. You’re probably thinking of his nephew Grigoriy Tsamblak, who was indeed metropolitan only in Lithuania.

As for Crimea – only OGB controlled parts of it and OGB lasted for less than half a century, so about that he was definitely wrong. Bulgar (not to be confused with Bulgarian) tribes might have lived in the northern parts of the peninsula for a while longer, but again nowhere as near as three centuries. He might be confusing Crimea with the Transcaucasian lands between the Caspian and Black seas, which were “controlled” for around the same time.

@”Rex Hatson” Do you happen to have any arguments about your thesis? Historians from all over the world would be thrilled to find any hard evidence on the language and religion of the early Bulgars, considering nothing has actually survived, besides speculation.
