Klarjeti, traversed by the Chorokhi (Çoruh), stretched from the Arsiani Range westwards, towards the Black Sea, and was centred in the key fortified trading town of Artanuji (now Ardanuç).

The region roughly corresponds to Cholarzene (Ancient Greek: Χολαρζηνή, Καταρζηνή) of Classical sources and probably to Kaţarza or Quturza of the earlier Urartian records.

[1] Klarjeti was one of the south-westernmost provinces of the Kingdom of Iberia, which appeared on the Caucasian political map in the 3rd century BC and was ruled—according to the medieval Georgian chronicles—by the Pharnavazid dynasty.

Deserted in an Arab invasion, Klarjeti was repopulated and developed into a major centre of Christian culture aided by a large-scale monastic movement initiated by the Georgian monk Gregory of Khandzta (759 – 861).

This line—known in the medieval Georgian records as the Sovereigns of Klarjeti (კლარჯნი ხელმწიფენი, klarjni khelmts'ip'eni)—was eventually dispossessed by their cousin Bagrat III, the first king of a unified Georgia, in 1010.
