Biography
Family Background and Early Years
Meng Tian's ancestral home was at Mengshan in the state of Qi, in present-day Mengyin County, Shandong, and his forebears were people of Qi. His grandfather Meng Ao moved from Qi to Qin during the reign of King Zhaoxiang of Qin, led campaigns against Han and Zhao, and eventually rose to Shangqing. His father Meng Wu was also a Qin general, once served as Neishi, and joined Wang Jian in the conquest of Chu. Meng Tian was born into a family of generations of generals. Under the influence of this background, he developed high ambitions, showed intelligence from an early age, studied military texts, and gradually acquired strong military knowledge. In his early career he served as an official responsible for judicial documentation, gaining administrative experience.
Campaigns Against Chu and Qi
In 225 BCE, the twenty-second year of Qin Shi Huang, Meng Tian participated in the campaign against Chu as a deputy commander under Li Xin. Li Xin and Meng Tian divided a 200,000-man army into two forces. Meng Tian captured Qinqiu in Chu, in present-day Linquan, Anhui, while Li Xin broke through Yan and Ying. Later, Lord Changping rebelled against Qin in the army's rear. Li Xin led his troops back west and joined Meng Tian at Chengfu, where they were pursued and heavily defeated by the Chu army, forcing the Qin army to withdraw. After this campaign, Qin Shi Huang replaced Li Xin with Wang Jian as commander, while Meng Tian's father Meng Wu served as deputy commander in the 600,000-man army that conquered Chu. In 221 BCE, the twenty-sixth year of Qin Shi Huang, Meng Tian was appointed general because of his family background, led an army against Qi, won a major victory, and was appointed Neishi, becoming the highest administrative official in the capital region.
Campaign Against the Xiongnu and Construction of the Great Wall
After Qin unified the six states, in 215 BCE, the thirty-second year of Qin Shi Huang, Meng Tian was ordered to lead 300,000 troops north against the Xiongnu. He recovered the Henan region, around present-day southern Hetao and Ordos in Inner Mongolia, established forty-four counties from Yuzhong, north of present-day Ejin Horo Banner, along the Yellow River to the Yin Mountains, and resettled people to populate the frontier counties. Meng Tian then supervised construction of the Great Wall from Lintao, present-day Min County in Gansu, in the west to Liaodong in the east, linking earlier Yan, Zhao, and Qin walls, using the terrain and establishing fortified positions to check Xiongnu incursions. He also oversaw construction of the Straight Road from Jiuyuan Commandery, southwest of present-day Baotou in Inner Mongolia, to Ganquan Palace, cutting through mountains and filling valleys over a length of 1,800 li, though the project was not completed. Meng Tian remained at Shang Commandery for more than ten years, and the Xiongnu, awed by his power, did not dare raid southward.
The Shaqiu Coup and the Fall of the Meng Family
In the winter of 210 BCE, the thirty-seventh year of Qin Shi Huang, the emperor fell ill while traveling toward Kuaiji and sent Meng Yi back to perform prayers to the mountains and rivers. Qin Shi Huang soon died at Shaqiu. Zhao Gao, Huhai, and Li Si conspired to forge an imperial order naming Huhai crown prince and commanding Fusu and Meng Tian to die. Fusu committed suicide upon receiving the order. Meng Tian was suspicious and requested that the matter be reconsidered, but the envoy handed him over to the authorities, imprisoned him at Yangzhou, and transferred command of his army to his deputy Wang Li. After Huhai learned that Fusu was dead, he initially intended to release Meng Tian, but Zhao Gao feared the Meng family's return to power and insisted on eliminating it. Meng Yi was imprisoned and killed first, after which Huhai sent an envoy to Yangzhou to order Meng Tian's death. Believing that three generations of his family had remained loyal to Qin, Meng Tian chose to uphold that loyalty and ultimately committed suicide by swallowing poison.
Meng Tian came of a family of generals through the generations. His grandfather Meng Ao had been a Qin commander against Han and Zhao and rose to the highest rank of minister, and his father Meng Wu, also a Qin general and at one time interior minister, joined Wang Jian in destroying Chu. Bright by nature and well read in the military texts, Meng Tian grew up in this setting and developed a high competence in arms.
In 225 BCE Qin sent Li Xin and Meng Tian against Chu in two columns with two hundred thousand men, Li Xin attacking Pingyu and Meng Tian Qin, with some early success; Li Xin's overconfidence then brought a heavy defeat, the armies withdrew and Qin replaced him with Wang Jian and six hundred thousand men. Meng Tian's chief achievements lay afterward in the north: he drove back the Xiongnu, recovered the lands south of the Yellow River bend, and directed the building of the great wall linking the older walls of Yan, Zhao and Qin into a line from Lintao in the west to Liaodong in the east; he also held Shangjun with troops for more than ten years, overawing the Xiongnu as the man in charge of Qin's northern defenses.
After the First Emperor's death Zhao Gao conspired with Li Si and Huhai, concealing the death and forging an edict condemning the heir Fusu and Meng Tian. Fusu killed himself; Meng Tian doubted the order and asked for confirmation, was handed over to the officials, and at last took poison. His brother Meng Yi was also executed, and the Meng family declined. Later tradition also connects him with the improvement of the writing brush, a story hard to verify but showing his place in cultural memory.
The wall Meng Tian built joined and extended the older walls of Yan, Zhao and Qin, a vast undertaking employing great numbers of garrison soldiers and laborers. The defense system of Qin's northern frontier included the wall, forts and commanderies, taking shape during the more than ten years he held Shangjun, and the frontier arrangements of the Han developed on that basis.
Meng Tian and Fusu were both in the north and on close terms. After the First Emperor's death Zhao Gao's forged edict condemned Fusu, who killed himself, while Meng Tian would not die without confirmation; he was finally killed with his brother Meng Yi, marking the thorough removal of the First Emperor's old servants.
Shangjun, where he was stationed, is roughly the north of present-day Shaanxi, the front line of Qin's defense against the Xiongnu. Qin set up commanderies there, built roads and moved convicts from the interior to settle the frontier, and Meng Tian's garrison worked with these measures to form the basic frame of Qin rule in the north.
His driving back of the Xiongnu is repeatedly cited in Han sources, standing beside the deeds of Li Guang, Wei Qing and Huo Qubing as part of the narrative of the northern frontier in the Qin-Han transition.
The First Emperor's trust in the Meng brothers stood out among Qin commanders: Meng Tian held military power in the north while Meng Yi took part in deliberations at the inner court, the two supporting each other — an arrangement destroyed at once by Zhao Gao's plotting after the emperor's death.
The wall he directed, together with the extension of Qin's commandery system and the building of roads, formed Qin's measures for securing the north, measures of very high cost and one aspect of the dynasty's heavy labor levies.
His death is dated to 210 BCE, the first year of the Second Emperor; his tomb is traditionally placed in the area of present-day Yulin in Shaanxi.
After Qin fell the Meng family's story served in early Han political writing as an example of Qin's merits and faults, his loyalty rewarded with death being told together with the fate of Fusu.
Meng Tian's military work was chiefly defensive against the Xiongnu, its core being to secure the newly taken lands south of the Yellow River bend and bring them into the commandery system. The Xiongnu raided south again at the end of Qin and the beginning of Han, and the allegiance of the Ordos changed repeatedly, the line he built not being maintained long — though the wall he constructed remained for centuries a geographic marker between farm and steppe.
Qin's management of the north also included building the straight road and moving populations, measures carried out in the newly taken regions while Meng Tian held Shangjun. The dynasty's road system and commanderies gave it more direct control of the northern frontier than the Warring States had had.
His career is often cited to illustrate the plight of great service repaid with death: over ten years commanding the north with conspicuous achievement, killed through palace intrigue, his fate mirroring the swift fall of Qin.
Of his military ability the *Records* says he served as a great general with considerable renown, his discipline and the effect of his northern garrison standing out in Qin's frontier defense.
His biography in the *Records* gives his family, his services and the manner of his unjust death in full, the basic material on him; there he says that his guilt deserved death and blames himself for "severing the earth's veins" in building the wall, a passage often quoted by later writers.
His chief opponents in the north were the Xiongnu chanyus Touman and afterward Modu, the Xiongnu not yet a unified and powerful state, so that the Qin offensive achieved considerable results.
After Meng Tian Qin's northern defenses were kept by his subordinates; in the disorders at the dynasty's end these garrisons were either recalled to the interior or broken by the Xiongnu, and the wall line fell into disuse.
After Qin the family's influence was gone, its story becoming a subject repeatedly taken up in later poetry and historical writing.
The plea he made while imprisoned is recorded at some length in the *Records*, setting out three generations of the Meng in Qin's service together with his own plight, and later readers have often responded with sympathy.
The First Emperor's management of the north in his last years worked with Meng Tian's campaigns, Qin's northern line being broadly established then, and the frontier arrangements of the following centuries mostly take that as their starting point.
That two brothers were both leading ministers is rare in Qin, and the rise and fall of the Meng is therefore a common case in discussions of the relations of ruler and minister under that dynasty.
His later commemoration centers largely on the wall and the historical memory of the northern frontier, while his unjust death is usually named with Fusu's as evidence of the political purge after the Second Emperor's accession.
Qin's commanderies and wall in the north were inherited and adjusted by the Han, a continuity showing that the works Meng Tian directed had lasting geographic and political meaning.
The place of his imprisonment in Shangjun and the place of his death are recorded with slight differences, his biography in the *Records* being the standard account.
His experience had some exemplary value for later ages, the Han campaigns against the Xiongnu resembling his operations in the Ordos.
Sima Qian had himself traveled through the Shangjun region and observed its works and defenses, so that his account carries elements of direct knowledge.
His figure appears repeatedly in later frontier poetry, linked with the image of the great wall as one of the symbols of northern defense.
Evaluations of him have always centered on loyalty repaid by death, his military achievements and tragic end standing together in the record.
He held important commands both before and after the unification of China, his military career spanning Qin's passage from kingdom to empire — unusual among the dynasty's generals.
His father Meng Wu's campaign with Wang Jian that destroyed Chu is one of the Meng family's most important achievements in the wars of unification.
He held such high posts as general-in-chief and interior minister, while his brother Meng Yi was among the highest ministers, the two of them conspicuous at court.
Tombs and shrines to him were built in later ages, and the northern frontier regions long commemorated him.
The loyal service of the two brothers and their deaths are recorded with the political purge that followed the Second Emperor's accession.
