Yujiulü Hulü (Chinese: 郁久閭斛律; pinyin: Yùjiǔlǘ Húlǜ) (died 414) was an early 5th century ruler of the Rouran, a confederation of nomadic tribes in Mongolia with the title Aikugai Khagan (藹苦蓋可汗; Rouran: Uqaqai Qaγan[1]).
[2] There is historical indication that Yujiulü Hulü (郁久閭斛律) began his rule in May 410 and, the following year, offered a tribute of three thousand horses to the Northern Yan ruler Feng Ba,[3] with a request to marry Feng Ba's daughter, Princess Lelang (樂浪公主), who was probably the daughter of Feng Ba's wife, Princess Sun.
As result, Yujiulü Buluzhen was set up as khagan, with Shuli (树黎) as chancellor.
Feng Ba treated him as an honored guest and, as originally planned, took Yujiulü's daughter, Zhaoyi (昭仪), as a concubine.
[3] Yujiulü Hulü requested that Feng Ba send an army to escort him home and, in May 414, Feng Ba, with some reluctance, gave him an escort commanded by general Wan Ling (萬陵) who, according to the account, returned after having killed Yujiulü Hulü along the way.
