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.
