noted the resemblance in the use of the kana sybigi with the Byzantine name and title basileus. Members of the upper social class bore the title boila (later boyar). The nobility was divided onto small and great boilas. In the 10th century, there were three classes of boyars: the six great boilas, the outer boilas, and the inner boilas, while in the mid-9th century there were twelve great boyars. The great boilas occupied military and administrative offices in the state, as well the council where they gathered for decisions on important matters of state.Bagaïns were the lesser class of the nobility, probably a military class which also participated in the council. The title bagatur, once as bogotor, is found in several instances within the inscriptions. It derives from Turkish bagadur (hero) and was a high military rank. The Bulgarian military commander who was defeated by the Croats in the Battle of the Bosnian Highlands (926) was called Alogobotur, which is actually a title comprised by alo (considered Turkic alp, alyp; chief) and bagatur. There are several title associations with uncertain meaning, such as boila kavkhan, ičirgu boila, kana boila qolovur, bagatur bagain, biri bagain, setit bagain and ik bagain.Kolober (or qolovur), a rank title, is cited in two inscriptions, and it derives from the Turkish term for a guide, golaghuz. The title župan, also once as kopan in the inscriptions, was often mentioned together with the bearer's name. They were traditionally seen as Slavic chiefs. It seems to have meant "head of a clan-district", as among the South Slavs (Croats, Serbs) where it was more widely used, it meant "head of a tribe" with a high district and court function. The title tarkhan probably represented a high military rank, similar to the Byzantine strategos, of the military governor of a province. The variations kalutarkan and buliastarkan are considered to be officers at the head of the tarkans. Curta interpreted the title zhupan tarqan as "tarqan of (all the) zhupans". Although it was not recorded on inscriptions, the title sampses is considered to be related to the royal court. The title tabare or iltabare, which derives from the old Turkish ältäbär, like sampses is not mentioned on inscriptions, but is related to the legates and ambassadors. The Anastasius Bibliothecarius listed Bulgarian legates at the Council at Constantinople in 869–870. They were mentioned as Stasis, Cerbula, Sundica (vagantur=bagatur), Vestranna (iltabare), Praestizisunas (campsis),
