突厥汗国
The Göktürks (First Turkic Kaganate) quickly spread west to the Caspian Sea. Between 581 and 603 the Western Turkic Khaganate in Kazakhstan separated from the Eastern Turkic Khaganate in Mongolia and Manchuria during a civil war. The Han-Chinese successfully overthrew the Eastern Turks in 630 and created a military Protectorate until 682. After that time the Second Turkic Khaganate ruled large parts of the former Göktürk area. After several wars between Turks, Chinese and Tibetans, the weakened Second Turkic Khaganate was replaced by the Uyghur Khaganate in the year 744.
