What is "gokturks"

The Celestial Turks or the Kok Turks ( Old Turkic: , Khotanese Saka Ttūrka, Ttrūka, Old Tibetan Drugu) and sometimes as its Anatolian Turkish form Göktürks (Celestial or Blue Turks), were a nomadic confederation of Turkic peoples in medieval Inner Asia. The Göktürks, under the leadership of Bumin Qaghan (d. 552) and his sons, succeeded the Rouran Khaganate as the main power in the region and established the Turkic Khaganate, one of several nomadic dynasties which would shape the future geolocation, culture, and dominant beliefs of Turkic peoples.
