Modu Chanyu
Modu Chanyu (冒顿单于) was a ruler of the Xiongnu, the steppe empire north of Han China, who is named in the standard histories 《史记》卷一百一十 and 《汉书》卷二十六. The particular record passages cited here are brief, but they establish the act for which he was remembered in Han memory: the encirclement of the founding Han emperor for seven days, and the submission of the Xiongnu nobility to his authority.

| Principal recorded act | Besieged Emperor Gaozu Liu Bang (刘邦) at Pingcheng (平城) for seven days 2 |

| Onomastic debate | One modern study argues 冒顿 was a chanyu title, not a personal name 3 |
What the standard histories record
The two record passages are brief but pointed. 《汉书》卷二十六 states that in the year Emperor Gaozu personally led his army against the Xiongnu, reaching Pingcheng, he was encircled by Modu Chanyu and was freed only after seven days (「为冒顿单于所围，七日乃解」). 2 This siege is remembered as the crisis at Baideng (白登). 8
《史记》卷一百一十 preserves the verdict of the steppe itself: after these events, "the Xiongnu nobles and great ministers all submitted, regarding Modu Chanyu as worthy" (「匈奴贵人大臣皆服，以冒顿单于为贤」). 1 The sentence records both political fact and judgment: his authority was accepted by the aristocracy, and it was accepted because they judged him capable.
The naming question
A study published by the Huhehaote (呼和浩特) Zhaojun Culture Research Association challenges this, arguing that for all chanyus before Xulvquanqu (虚闾权渠) the histories record the chanyu title rather than the name, and that treating Tou Man and 冒顿 as personal names is a long-standing misunderstanding. It supports the reading with the succession formula in 《史记》: after Modu's death, "his son Ji Zhou (稽粥) was established, titled Lao Shang (老上) Chanyu", where Ji Zhou is a name and Lao Shang a title. 3 The same study notes that Modu's letter to the Han court styling himself "the Chanyu of the Xiongnu established by Heaven" likely reached the Han in Chinese drafting, so its phrasing reflects Han imitation as well as steppe self-presentation. 3
Chronology carries its own uncertainty. 4
Political influence
Modern historians treat Modu as the builder of Xiongnu state institutions rather than a mere raider. A study of Xiongnu kingship argues that he perfected the existing union of military and civil administration in Xiongnu society, and that at the Baideng siege the Han emperor saw Xiongnu cavalry arrayed on all four sides in orderly ranks, evidence of disciplined organization rather than a loose tribal host. 5 The chanyu title itself became part of a durable Inner Asian political tradition, persisting until it was replaced by the title khan around the fourth century AD. 3
Nicola Di Cosmo, a historian of early China and Inner Asia, summarizes Modu's achievement as the exploitation of the militarization that the Qin invasion had forced on the Xiongnu, creating the centralized political structure that made the empire possible. 6 The 《中国民族史》, by contrast, describes the polity he founded as the strongest slave-holding state of the northern steppe, which "united into one household all the bow-drawing peoples". 7
Assessment
The standard history's own assessment is the sentence of universal submission and esteem quoted above. 8
Legacy
Sima Qian gave the Xiongnu a dedicated chapter, and later dynastic histories continued the practice for as long as the people endured; a modern popular biography, 大漠雄鹰：冒顿单于传奇 (Eagle of the Great Desert: The Legend of Modu Chanyu), presents his life and Xiongnu–Han relations for general readers. 10
