Yujiulü Doulun

Yujiulü Doulan was khagan of the Rouran with the title of Fugudun Khagan. He was the son of Yujiulü Yucheng.

Reign

Yujiulü Doulun succeeded his father as khagan of the Rouran in 485. His reign saw the resumption of raids on the Northern Wei border but did not bring visible results. In Chinese sources, the years of his reign are called the "period of mercy", but at this time in the khaganate there were frequent destructive wars between high ranking nobles. When nobles asked Doulun to make peace with Wei, he accused them of treason and ordered them to be executed, together with whole clans and up to three tribes.
Doulun and his uncle Nagai were defeated by Gaoche ruler Afuzhiluo and his younger cousin Qiongqi in 487. In 488, he invaded Yiwu with 3,000 soldiers and returned to the steppes. The eastern wing of the Rouran fell into Khitan and Kumo Xi hands in 490.
Starting from 492, Doulun's cruelty and losses in battles made his nobles to grow distressful. They persuaded Nagai to be the khagan. Nagai initially refused and said that Doulun was a legal khagan until death. This was a signal for the nobles who killed Doulun and his mother in a coup d'état, brought their corpses to Nagai and subsequently proclaimed him khagan.
