Organa (Bu-Yurgan) was Kubrat's maternal uncle of the Ermi clan. According to John of Nikiu, he was regent (kavkhan) over the tribe of the Onogur Bulgars from 617 to 630 in place of his nephew, Kubrat, for the time Kubrat was growing up as a hostage in the Byzantine Empire and there is information that Organa accompanied Kubrat on his initial trip to Constantinople. Some historians identified Organa with Gostun and Western Turks qaghan Mohotu (Külüg Sibir). Panos Sophoulis considered that Organa is in fact a Turkic title (or-ḡan/qan) rather than a proper name.
