The Oghuz Turks (Middle Turkic: ٱغُز, romanized: 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, much of the populations of Turkey, Azerbaijan and Turkmenistan are descendants of Oghuz Turks. The term Oghuz was gradually supplanted by the terms Turkmen and Turcoman (Ottoman Turkish: تركمن, romanized: Türkmen or Türkmân) by the 13th century.
The Oghuz confederation migrated westward from the Jeti-su 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.
