PROFILE
Huyandi Chanyu (d. 68 BCE) was a prominent supreme ruler of the Xiongnu during the Western Han reigns of Emperor Zhao and Emperor Xuan. He was a son of Hulugu Chanyu. In 85 BCE, following Hulugu's death, Empress Zhuanqu and minister Wei Lü bypassed the designated heir to install Huyandi (then Left Guli King), igniting intense internal fractures among other royal princes. Throughout his seventeen-year reign, Huyandi pursued a dual policy of intermittent diplomatic overtures—including repatriating long-detained Han ambassador Su Wu in 81 BCE—and violent military confrontations with Han frontier garrisons and the western realm of Wusun. Around 71 BCE, a catastrophic winter blizzard combined with coordinated assaults by the Han, Wusun, Dingling, and Wuhuan devastated Xiongnu military strength. Upon his death in 68 BCE, his younger brother Xulüquanqu succeeded to the throne.

BIOGRAPHY
Biography
Disputed Succession
Huyandi was the son of Hulugu Chanyu, serving initially as the Left Guli King. In 85 BCE, Hulugu fell terminally ill and originally designated his younger brother, the Right Guli King, as his successor. Upon Hulugu's death, Empress Zhuanqu conspired with court minister Wei Lü to conceal the sovereign's demise, forging an imperial consensus that elevated Huyandi. The Wise King of the Left and Right Guli King refused to attend the seasonal assembly at the Ordo court, initiating severe aristocratic fractures within the steppe realm.
War and Diplomacy with Han
Upon taking power, Huyandi sent envoys to Chang'an seeking renewal of the heqin marital alliance. In 83 BCE, however, Xiongnu forces raided Dai Commandery, slaying the Han military commander. Huyandi subsequently adopted Wei Lü's defensive advice to build storage fortresses and stockpile grain along northern routes. In 81 BCE, in a notable gesture of diplomatic détente, Huyandi released and repatriated long-held Han envoys, including Su Wu. Despite this thaw, raiding resumed in 80 BCE and 78 BCE along the Hexi Corridor near Zhangye, where Han garrisons repelled nomadic cavalry.
The Wusun Campaigns and Decline
In the western regions, Xiongnu pressure on Wusun provoked Han military intervention. In the winter of 72–71 BCE, Huyandi personally campaigned against Wusun. On their return march across the northern steppe, a ferocious blizzard decimated hundreds of thousands of livestock and troops. Taking advantage of their vulnerability, the Dingling from the north, Wuhuan from the east, and Wusun from the west struck simultaneously. Huyandi died in 68 BCE, leaving a critically weakened confederation to his brother Xulüquanqu.
Major Activities
Factional Politics and Centralization
Huyandi's reign highlighted increasing internal factionalism among Xiongnu royal princes following irregular successions.
Diplomatic Exchanges and Military Attrition
The repatriation of Su Wu stood as the major diplomatic milestone of his reign, balanced against devastating strategic overextension in Central Asia against Wusun and Han alliances.
Personal Relations
- Hulugu Chanyu: Father and predecessor.
- Empress Zhuanqu: Imperial dowager who orchestrated his ascension.
- Wei Lü: Senior imperial adviser who shaped military fortification strategy.
- Xulüquanqu Chanyu: Younger brother and royal successor.

Historical Assessment
The Book of Han (Han Shu) details Huyandi's protracted struggles against internal dissent, Han counteroffensives, and climatic disaster, presenting his reign as a critical turning point that led directly to the subsequent five-way civil war of the Xiongnu.
