Rouran Khaganate

The Rouran Khaganate, also Juan-Juan Khaganate, was a tribal confederation and later state founded by a people of Proto-Mongolic Donghu origin. The Rouran supreme rulers used the title of "khagan", a popular title borrowed from the Xianbei. The Rouran Khaganate lasted from the late 4th century until the middle 6th century, when they were defeated by a Göktürk rebellion which subsequently led to the rise of the Turks in world history.
