Uyghurs
Later Turkic peoples include the Karluks (mainly 8th century), Uyghurs, Kyrgyz, Oghuz (or Guz, Uz, Ghuzz, etc.) Turks, and Turkmens. As these peoples were founding states in the area between Mongolia and Transoxiana, they came into contact with Muslims, and most gradually adopted Islam. However, there were also (and still are) some other groups of Turkic people who were (and are) non-believers or those belonging to other religions, including Christians, Jews (see Khazars), Buddhists, and Zoroastrians.
