Ajjar of Bulgaria
Ajjar or Ayyar (Bulgarian: Айяр), is the name assigned by the 17th century Volga Bulgar source Ja'far Tarikh (a work of disputed authenticity), to the successor of Tervel on the throne of Bulgaria. The name Ajjar is otherwise completely unattested in the sources, but the Namelist of Bulgarian Rulers contains indications of two damaged records between the entries for Tervel and Sevar.
