The origin of all of these tribes is traced to 24 ancient Oghuz tribes, among which the Salur tribe played a prominent role as its people are considered the ancestors of modern Turkmen tribes such as Teke, Yomut and Ersari.
In the early Middle Ages, Turkmens called themselves Oghuz; in the Middle Ages, they took the ethnonymTurkmen. These early Oghuz Turkmens moved westward from the Altai Mountains through the Siberian steppes, and settled in the region now known as Turkmenistan. Further westward migration of the Turkmen tribes from the territory of modern Turkmenistan and the rest of Central Asia started from the 11th century and continued until the 18th century. These Turkmen tribes played a significant role in the ethnic formation of such peoples as Anatolian Turks, Turkmens of Iraq, and Syria, as well as the Turkic population of Iran and Azerbaijan. To preserve their independence, those tribes that remained in Turkmenistan were united in military alliances, although remnants of tribal relations remained until the 20th century. Their traditional occupations were farming, cattle breeding, and various crafts. Ancient samples of applied art (primarily carpets and jewelry) indicate a high level of folk art culture.
The Treaty of Akhal (Russian: Ахалский договор, Persian: پیمان آخال), also known as Akhal-Khorasan Boundary Convention, was an agreement signed between Qajar Iran and Imperial Russia on 21 September 1881 to mark Iran's official recognition of Khwarazm's (mostly the territory of present-day Turkmenistan) annexation by the Russian Empire.
The title of the treaty is derived from the name of the vast region north of Khorasan where the Turkmen tribe of Tekke lived – Akhal.
