The Pashtuns began as a union of largely East-Iranian tribes which became the initial ethnic stratum of the Pashtun ethnogenesis, dates from the middle of the first millennium CE and is connected with the dissolution of the Epthalite (White Huns) confederacy. ... Of the contribution of the Epthalites (White Huns) to the ethnogenesis of the Pashtuns we find evidence in the ethnonym of the largest of the Pashtun tribe unions, the Abdali (Durrani after 1747) associated with the ethnic name of the Epthalites — Abdal. The Siah-posh, the Kafirs (Nuristanis) of the Hindu Kush, called all Pashtuns by a general name of Abdal still at the beginning of the 19th century.
