They also can be found among Ersari Turkmens, who live predominantly in the Lebap velayat (region) of Turkmenistan and northern provinces of Afghanistan.

In his history work Shajara-i Tarākima (Genealogy of Turkmens), the Khan of the Khanate of Khiva and historian Abu al-Ghazi Bahadur mentions Begdili among 24 Oghuz tribes, direct descendants of Oghuz-khan, who was the ancient progenitor of the Oghuz people, and the name of the tribe translates as “reputable”.

[1] The Anushteginid dynasty, which ruled vast parts of Central Asia from 1077 to 1231 under the title of Khwarazmshahs, descended from the Begdili tribe.

In the Middle Ages, a large group of Begdili Turkmens migrated from Central Asia to the territory of modern Iran, Azerbaijan and Turkey.

Information about the origin of the Begdili mostly comes from the famous statesman and historian of the Ilkhanate, Rashid-al-Din Hamadani in his "Jami' al-tawarikh"[5] (Compendium of Chronicles), and from the work of the Khan of Khiva Abu al-Ghazi Bahadur, titled "Genealogy of Turkmens".
