Tabasarans (endonym – Tabasaranar) are concentrated in the southeastern slopes of the Greater Caucasus Range from ancient times. These Dagestanian people, whose language belongs to the Lezgin group of the Ibero-Caucasian language family, is mentioned in the Armenian bibliography of the V century- in the works of M. Khorenatsi, Yeghishe and Buzand, in the form of ''t‘awaspar(k‘)''. Along with the Armenian sources, the medieval Arabic historiography plays an important role in the examination of the ethnonym of Tabasaran people, where the country of Tabasarans is mentioned as Tabarsaran and the people are called ahl ṭabarsaran (inhabitant of Tabarsaran) or al-ṭabarsaraniya (Tabarsaranian).
