Yagma

The Yagmas, or Yaghmas, were a medieval tribe of Turkic people that came to the forefront of history after the disintegration of the Western Turkic Kaganate. They were one component of a three-member confederation known as Uch Oguz, which consisted of Yagma, the Karluks, and the Chigils. From the seventh century until the Karakhanid period, the Yagma were recorded in Arabic, Muslim, and Chinese accounts as a prominent and powerful political entity in the Tarim Basin, Dzungaria, and Jeti-su. Along with the Karluks, Chigils, and other tribes, the Yagmas founded the Karakhanid state.
