Yujiulü Hulü

Yujiulü Hulü ( _zh. 郁久閭斛律; pinyin: Yùjiǔlǘ Húlǜ) (died ) was an early 5th century Aikugai Khan (藹苦蓋可汗) (ruler) of the Rouran, a confederation of nomadic tribes in Mongolia.

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, with a request to marry Feng Ba's daughter, Princess Lelang, who was probably the daughter of Feng Ba's wife, Princess Sun. Feng Ba's brother, Feng Sufu, suggested refusing the request and sending the daughter of one of Feng Ba's concubines instead, but Feng Ba was apparently convinced that an alliance with Rouran would be beneficial to his state, and agreed to give Princess Lelang in marriage to Yujiulü Hulü.

In 414, the fourth year of his rule, as he was, in turn, about to oversee the marriage of one of his own daughters to Feng Ba, Yujiulü Hulü was overthrown by his nephew Yujiulü Buluzhen (郁久閭步鹿真) who, along with the coup leaders, sent Yujiulü Hulü and his daughter to Northern Yan. Feng Ba treated him as an honored guest and, as originally planned, took his daughter as a concubine. 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.
