突厥汗国

The First Turkic Khaganate, also referred to as the First Turkic Empire, the Turkic Khaganate or the Göktürk Khaganate, was a Turkic khaganate established by the Ashina clan of the Göktürks in medieval Inner Asia under the leadership of Bumin Qaghan (d. 552) and his brother Istämi. The First Turkic Khaganate succeeded the Rouran Khaganate as the hegemonic power of the Mongolian Plateau and rapidly expanded their territories in Central Asia. The khaganate became the first Central Asian transcontinental empire from Manchuria to the Black Sea.

Although the Göktürks spoke a Siberian Turkic language, the direct predecessor to the Orkhon Turkic of the Second Turkic Khaganate, the First Khaganate's early official texts and coins were written in Sogdian. It was the first Turkic state to use the name Türk politically. The Old Turkic script was invented in the first half of the sixth century.
