Oghuz Turks

The Oghuz Turks (Middle Turkic: ٱغُز, romanised: Oγuz) were a western Turkic people who spoke the Oghuz branch of the Turkic language family. In the 8th century, they formed a tribal confederation conventionally named the Oghuz Yabgu State in Central Asia. Today the Turkmen, Azerbaijanis and Turks are descendants of Oghuz Turks. The term Oghuz was gradually supplanted by the terms Turkmen and Turcoman (Ottoman Turkish: تركمن, romanised: Türkmen or Türkmân) by the 13th century.

The Oghuz confederation migrated westward from the Jetisu area after a conflict with the Karluk allies of the Uyghurs. In the 9th century, the Oghuz from the Aral steppes drove Pechenegs westward from the Emba and Ural River region. In the 10th century, the Oghuz inhabited the steppe of the rivers Sari-su, Turgai and Emba north of Lake Balkhash in modern-day Kazakhstan.

They embraced Islam and adapted their traditions and institutions to the Islamic world, emerging as empire-builders with a constructive sense of statecraft. In the 11th century, the Seljuk Oghuz clan entered Persia, where they founded the Great Seljuk Empire. The same century, a Tengriist Oghuz clan, also known as Uzes or Torks, overthrew Pecheneg supremacy in the frontier of the Russian steppes; those who settled along the frontier were gradually Slavicized; the almost feudal Black Hat principality grew with its own military aristocracy.
