Luandi Touman

Biography

Family Background and Early Life

Touman came from the Luandi clan, one of the prominent Xiongnu clans. Very little is recorded about his early life. It is known only that by the late Warring States period he had become leader of the Xiongnu tribal confederation. The "Account of the Xiongnu" in the Records of the Grand Historian states: "At that time the Donghu were strong and the Yuezhi flourishing; the Xiongnu Chanyu was named Touman." This is the first surviving historical record to use the title Chanyu for a named Xiongnu ruler. The names of earlier Xiongnu leaders are not recorded, nor are they described with the Chanyu title, and Touman is therefore treated in the source text as marking the beginning of Xiongnu state formation. The Xiongnu referred to the Chanyu as "Chengli Gutu Chanyu," explained as meaning "Son of Heaven," and the source text interprets the title itself as reflecting a transition from clan-based tribal organization toward state formation.

Establishing the Xiongnu Polity

During Touman's reign, Xiongnu power extended broadly from the Donghu in the east to the Yuezhi in the west, from Qin territory in the south to the Dingling in the north. He integrated nomadic groups between the Yin Mountains and the Hetao and began to establish a military-administrative structure, laying a foundation for Modu Chanyu's later expansion. According to the source text, Xiongnu social structure changed substantially in this period: clan and tribal leaders gradually became officials of a developing state, and slave institutions began to emerge. Although Touman's rule made the Xiongnu an important power on the northern steppe, they remained relatively weaker than the Donghu and Yuezhi.

War with the Qin Dynasty

In 215 BCE, the thirty-second year of Qin Shi Huang, after Qin had unified the six states, Qin Shi Huang sent Meng Tian north against the Xiongnu. Meng Tian seized the Hetao region south of the Yellow River. Unable to withstand the Qin offensive, Touman led his people north of the Yin Mountains. Qin established forty-four counties in the Hetao and built the Great Wall to defend against the Xiongnu. For more than a decade thereafter Xiongnu power was restricted north of the Yin Mountains and could not move south. In 210 BCE, the thirty-seventh year of Qin Shi Huang, Meng Tian and Fusu died in succession. As Qin descended into internal turmoil and frontier troops gradually withdrew, the Xiongnu were able to cross the Yellow River again and face Qin along the old Great Wall frontier.

Succession Dispute and Death

Touman's crown prince was his eldest son Modu. Touman later favored a Yanzhi who bore him a younger son and sought to depose Modu and make the younger child crown prince. He therefore sent Modu to the Yuezhi as a hostage and soon launched a sudden attack on them, hoping the Yuezhi would kill Modu. Modu stole a fine horse and escaped back to the Xiongnu. Impressed by his courage, Touman placed him in command of ten thousand cavalry. Modu, bearing a grudge, created the whistling arrow and used it to train his personal troops, ordering them to shoot whatever target his arrow struck and executing anyone who failed to obey. He successively fired at game, his own prized horse, and his beloved wife, killing all who hesitated to follow his shot. Once his troops' loyalty had been tested, Modu fired a whistling arrow at Touman during a hunt; his followers shot with him and killed Touman on the spot. Modu then executed his stepmother, younger half-brother, and disobedient ministers and proclaimed himself Chanyu.

Major Activities

Unifying Xiongnu Tribes

Touman was the first Xiongnu leader recorded with the title Chanyu. Through military conquest and political integration, he brought together nomadic tribes between the Yin Mountains and the Hetao and formed the rudiments of a Xiongnu polity. The process was gradual and involved confrontation and negotiation with neighboring powers such as the Donghu and Yuezhi. The source text presents Touman's reign as providing a political foundation for the transition of the Xiongnu from clan-based society toward a slave-owning state.

Military Confrontation with Qin

In 215 BCE Meng Tian seized the Henan region and forced Touman north. The source text describes this as the first large-scale military conflict between the Xiongnu and a unified Chinese dynasty. Qin established counties and fortified settlements in the Hetao and built the Great Wall, confining Xiongnu power north of the Yin Mountains. Touman was defeated but not destroyed; he preserved Xiongnu strength and, when Qin frontier defenses weakened late in the dynasty, moved south again, creating conditions for expansion under Modu.

The Succession Dispute and the Whistling-Arrow Coup

Because Touman favored his younger son, he sent Modu to the Yuezhi as a hostage and attacked the Yuezhi in an attempt to have him killed. Modu escaped by stealing a horse, after which Touman placed him in command of ten thousand cavalry. This gave Modu the military power needed to stage a coup. Modu trained his personal troops with whistling arrows and ultimately killed Touman during a hunt. The episode was not only an internal Xiongnu transfer of power but also deeply affected the subsequent political trajectory of the Xiongnu.

Personal Relations

• Modu: eldest son; later Chanyu of the Xiongnu; killed Touman and seized the throne
• Younger son: child of Touman and his favored Yanzhi; Touman's effort to make him crown prince caused the succession dispute; later executed by Modu
• Favored Yanzhi: Touman's favored consort; executed after Modu's coup
• Meng Tian: Qin general who defeated Touman and seized the Henan region
• Qin Shi Huang: Qin emperor who launched the campaign against the Xiongnu
• Yuezhi: western neighbors of the Xiongnu; Touman sent Modu to them as a hostage and then attacked them, after which Modu escaped on a stolen horse
• Donghu: eastern neighbors of the Xiongnu who were stronger than them during part of Touman's reign

Historical Assessment

Han Period

Sima Qian recorded Touman's activities in the "Account of the Xiongnu" in the Records of the Grand Historian, writing that "at that time the Donghu were strong and the Yuezhi flourishing; the Xiongnu Chanyu was named Touman," thereby identifying him as the earliest recorded Xiongnu Chanyu. Ban Gu followed this account in the "Account of the Xiongnu" in the Book of Han and added details concerning Touman's conflict with Qin and the succession dispute. Han historians described Touman comparatively objectively and offered no explicit moral judgment, but their narrative implies that his attempt to depose his elder son in favor of a younger one directly led to his death.

Wei, Jin, and Northern and Southern Dynasties

After Helian Bobo founded the Great Xia polity, he claimed descent from Yu the Great rather than directly associating himself with Touman. Xiongnu Liu regimes, such as that of Liu Yuan, claimed descent from Modu and thereby indirectly acknowledged Touman's position as an ancestral figure. The Book of Jin, in its records of Helian Bobo, states that he claimed descent from Yu and longstanding residence in the northern regions without mentioning Touman, while the Xiongnu Liu clan's claim of descent from Modu illustrates Touman's symbolic importance among later groups claiming Xiongnu ancestry.

Tang and Song Periods

Tang historian Du You followed the Records of the Grand Historian and Book of Han in the Tongdian, treating Touman as the starting point of Xiongnu state formation. Song historian Sima Guang recorded Touman's war with Meng Tian and Modu's patricide in the Comprehensive Mirror in Aid of Governance and commented that Modu's brutality was worse than that of beasts, without offering a separate judgment of Touman. Tang and Song historians generally viewed Touman politically, treating his reign as laying groundwork for the rise of the Xiongnu.

Modern Assessments

Modern scholar Lin Gan, in History of the Xiongnu, identifies Touman as a founder of the Xiongnu state and argues that during his reign Xiongnu society moved from clan and tribal organization toward a slave-owning system, while the emergence of the Chanyu title marked the establishment of state institutions. Ma Changshou, in The Northern Di and the Xiongnu, argues that Touman's weakness lay in his inability to respond effectively to Qin military pressure, but that his political integration prepared the way for Modu's expansion. Japanese scholar Mori Masao and others have likewise treated Touman as a transitional and important figure in Xiongnu history.
