Although there have been several suggested theories for the origin of the Bakhtiyaris, historians and researchers generally agree that they are Lurs. According to folklore, the Lurs are descended from a group of youngsters who survived and fled from the demon Zahhak, a demonic figure who is mentioned in Zoroastrian mythology, as well as the Shahnameh. They took shelter in Zardkuh and Kuhrang, where they named themselves Lur ("nomadic"). Due to their luck of escaping danger throughout their history, they called themselves bakhtiyar ("fortunate"). In scholarship, it has been suggested Bakhtiyaris are descended from the Uxian tribe, who clashed with the Macedonian king Alexander the Great (r. 336–323 BC) in Khuzestan 330 BC.[6]
A second theory suggests that the Bakhtiyaris were originally from Fars, but were settled to the north of Isfahan and Khuzestan after the legendary king Kay Khosrow conquered Media. A third theory suggests that the Bakhtiyaris were descended from the Mardi, a nomadic warrior tribe that lived around the Caspian coast of northern Iran. Due to the close resemblance to the names Bakhtiyari and Bakhtari (Bactrian), some historians have suggested that the Bakhtiyaris are descended from the Greeks who ruled over Bactria. The resemblance between Bakhtiyari and Greek dance has been used as further proof. Other historians consider the Bakhtiyaris to have resided in their area for a long time, and that they named themselves after the ancient Persian word Bakhtar ("the West") due to their geographical position.[6]
Another theory supported by some historians is that the Bakhtiyaris are descended from Izz al-Dawla Bakhtiyar (r. 967–978), the Buyid ruler of Iraq. The name of the latter is first attestation of the word Bakhtiyar. The Bakhtiyaris themselves consider their name to be derived from the word Bakhtiyarwand, the name of the offspring of Bakhtiyar, a distinguished figure of Lur-i Buzurg (Greater Lur)
