Duke Ligong of Qin

Biography

Family Background and Accession

Duke Ligong of Qin was the son of Duke Dao of Qin and belonged to the Ying clan. His title appears in several forms in historical texts. The “Basic Annals of Qin” in the Records of the Grand Historian writes it as “Duke Ligong of Qin” using the characters Duke Ligong; the Shiji Zhengyi writes “Duke Ligong of Qin” with Duke Ligong; and the “Account of the Western Qiang” in the Book of the Later Han calls him “Duke Li of Qin.” The later conventional form is Duke Ligong of Qin. On the basis of the line “Duke Ligong enjoyed the state for thirty-four years” in the “Basic Annals of Qin Shi Huang,” his personal name has sometimes been reconstructed as La. Duke Dao of Qin reigned for fourteen years, from 490 to 477 BCE, and Duke Ligong succeeded him after his death. This was the late Spring and Autumn period, when the six ministerial clans of Jin were locked in intense rivalry and Chu was constrained by the aftermath of the Wu-Yue struggle for supremacy. Qin was relatively stable in the west and had room to recover and seek opportunities for expansion.

Early Reign: Tribute from All Directions and Management of the Western Frontier

In 475 BCE, the second year of Duke Ligong's reign, Shu sent tribute. Shu, in the present-day Sichuan Basin, bordered Qin to the southwest and at this time was not strong enough to compete directly with Qin, so it took the initiative to maintain friendly relations. In the fifth year, 472 BCE, Chu sent tribute. Chu had not yet fully recovered from the severe blows it had suffered from Wu late in the Spring and Autumn period and adopted a relatively deferential posture toward Qin. In the sixth year, 471 BCE, Yiqu sent tribute and Mianzhu requested aid. Yiqu was a major western Rong polity active in present-day eastern Gansu and northern Shaanxi and was then still engaged in peaceful relations with Qin. Mianzhu was another western Rong group and appealed to Qin because it was being pressed by other Rong peoples.

In the seventh year, 470 BCE, a comet appeared in the sky, and Prince Ying of Chu fled to Qin. Historical sources say little about Prince Ying. The “Chronological Table of the Six States” in the Records of the Grand Historian records only that in the nineteenth year of King Hui of Chu, “Prince Ying fled to Qin”; his identity and the reason for his flight cannot be determined in detail. In the tenth year, 467 BCE, another comet appeared, and a shuzhang led troops to repair Wei City, north of present-day Ruicheng County in Shanxi. Wei City lay on the Qin-Jin frontier and was then a Qin border settlement. Strengthening its defenses was intended to consolidate Qin's eastern frontier.

Middle Reign: Eastward Advance and Western Campaigns

In 463 BCE, the fourteenth year of Duke Ligong's reign, both Jin and Chu sent tribute, suggesting an increase in Qin's standing among the feudal states. In the sixteenth year, 461 BCE, Qin dug a trench along the Yellow River. The “Basic Annals of Qin” in the Records of the Grand Historian describes this as “trenching beside the river,” indicating defensive works along the Yellow River. Qin also sent twenty thousand troops against Dali, a western Rong power east of present-day Dali County, Shaanxi, and captured its royal city, while at the same time repairing Pangxi City northeast of present-day Baishui County, Shaanxi. Dali had long occupied the eastern Guanzhong region. By driving it out, Qin gained control over key transportation routes along the lower Luo River and the western bank of the Yellow River.

In the twentieth year, 457 BCE, Duke Ligong personally led troops against Mianzhu. Mianzhu was located around present-day Tianshui in Gansu. It had previously requested Qin aid but may later have turned against Qin, prompting Duke Ligong to campaign in person. In 456 BCE, the twenty-first year, Qin established a county at Pinyang, north of present-day Fuping County, Shaanxi. Pinyang lay in the heart of Guanzhong, and the creation of a county represented a further institutionalization of Qin control there. In the same year Jin captured Wucheng, east of present-day Huaxian in Shaanxi. Wucheng had been Qin territory, and its loss showed that Qin remained on the defensive in the continuing struggle with Jin over the Hexi region.

Later Reign: Zhi Refugees and Southern Expansion

In 453 BCE, the twenty-fourth year of Duke Ligong's reign, internal conflict in Jin culminated in the defeat and death of Zhi Xiangzi, also known as Zhi Boyao. His territory was divided among Zhao, Han, and Wei, in the process later known as the “Partition of Jin.” In 452 BCE, the twenty-fifth year, Zhi Kai, a clansman of Zhi Xiangzi, led inhabitants of his settlement in fleeing to Qin. In 448 BCE, the twenty-ninth year, Zhi Kuan also led followers to Qin. The Zhi clan had been one of the old aristocratic families of Jin. The flight of its surviving forces to Qin shows both Qin's willingness to accept political refugees from the Jin crisis and the acquisition of population and resources that strengthened Qin.

In 451 BCE, the twenty-sixth year, the Left Shuzhang built a city at Nanzheng, in present-day Hantai District of Hanzhong, Shaanxi. Nanzheng lay in the Hanzhong Basin and controlled transportation routes between Qin and Shu. Building the city marked the formal extension of Qin influence into Hanzhong and prepared the ground for later competition with Shu and Chu over the Han River basin. In 449 BCE, the twenty-eighth year, Yue sent envoys to escort Duke Ligong's daughter for marriage. After King Goujian of Yue destroyed Wu and advanced north in pursuit of hegemony, marriage ties with Qin served to cultivate relations with a major western power. In 445 BCE, the thirty-second year, Chu and Qin formed an alliance. During the reign of King Hui of Chu, Qin-Chu relations improved, temporarily easing tensions in the Han River region.

Final Years and Death

In 444 BCE, the thirty-third year of Duke Ligong's reign, Qin sent troops against Yiqu and captured its ruler. Yiqu had previously sent tribute to Qin but relations had since deteriorated. The large Qin attack and capture of the Yiqu ruler represented a major blow to western Rong power. In 443 BCE, the thirty-fourth year, a solar eclipse occurred; daylight darkened and stars became visible. Duke Ligong died in the same year and was buried at Renli, or according to another reading, Ruli. He had two sons, Duke Zao of Qin and Duke Huai of Qin. His eldest son, Duke Zao, succeeded him.

Major Activities

Military Campaigns

Duke Ligong repeatedly used military force during his reign in two principal directions. The first was against the western Rong. In 461 BCE he sent twenty thousand troops against Dali and captured its royal city; in 457 BCE he personally campaigned against Mianzhu; and in 444 BCE he attacked Yiqu and captured its ruler. These campaigns strengthened Qin control in western and northern Guanzhong and weakened threats from western Rong groups. The second direction was the east. In 461 BCE Qin dug a trench along the Yellow River and repaired Pangxi City to strengthen eastern defenses. In 456 BCE Jin captured Wucheng, and Qin failed to hold this eastern strongpoint, showing that Qin still occupied a defensive position in the contest with Jin over the Hexi region.

Diplomacy

Qin maintained active diplomatic relations during Duke Ligong's reign. Shu in 475 BCE, Chu in 472 BCE, Yiqu in 471 BCE, and Jin and Chu in 463 BCE all sent tribute, indicating Qin's influence in surrounding regions. In 449 BCE Yue came to escort Duke Ligong's daughter for marriage, creating a Qin-Yue marital alliance. In 445 BCE Chu and Qin formed an alliance, ending a period of tension. Qin also received a number of political refugees: Prince Ying of Chu in 470 BCE and members of the Zhi clan in 452 and 448 BCE. Accepting these exiles both reflected a strategy of attracting people and demonstrated the complexity of interstate competition at the time.

Internal Administration

Internal development under Duke Ligong was expressed mainly in the establishment of counties and construction of fortified settlements. In 456 BCE Qin established a county at Pinyang, an important measure in extending the county system through central Guanzhong. In 451 BCE the Left Shuzhang built a city at Nanzheng, extending Qin's control into Hanzhong. The repair of Wei City in 467 BCE and Pangxi City in 461 BCE strengthened border settlements. These measures provided administrative and military foundations for Qin's later expansion.

Relations with the Zhi Clan of Jin

In 453 BCE, the twenty-fourth year of Duke Ligong, Zhi Xiangzi, also known as Zhi Boyao, was defeated and killed by the combined forces of Zhao, Han, and Wei, and the Zhi lands were divided. The event was a key stage in the Partition of Jin. Survivors of the Zhi clan then fled to Qin: Zhi Kai in 452 BCE and Zhi Kuan in 448 BCE. As one of Jin's six great ministerial clans, the Zhi had possessed significant political resources. Qin's acceptance of its remnants brought population and land while also involving Qin politically in Jin's internal turmoil.

Historical Assessment

Pre-Qin and Qin-Han Periods

• The “Basic Annals of Qin” in the Records of the Grand Historian records Duke Ligong mainly through annalistic events without explicit praise or blame, but gives considerable detail on his campaigns, acceptance of Zhi refugees, establishment of counties, and construction of cities, showing that Sima Qian regarded him as an important link in Qin's historical development.
• The Qin records appended to the “Basic Annals of Qin Shi Huang” in the Records of the Grand Historian give his title as “Duke Ligong” using the characters Duke Ligong and state that he “enjoyed the state for thirty-four years,” an important basis for later reconstruction of the Qin succession.
• The “Account of the Western Qiang” in the Book of the Later Han calls him “Duke Li of Qin” and records his campaigns against Dali and Yiqu, presenting Qin's suppression of western Rong peoples from the perspective of the western Qiang.

Tang and Song Periods

• The Tang scholar Sima Zhen, in his Shiji Suoyin, examined the forms of Duke Ligong's title and argued that “Duke Ligong” written with Duke Ligong and the later form Duke Ligong referred to the same ruler. This view was followed by later scholars.
• The Song scholar Lü Zuqian included Qin's campaigns against Dali and Yiqu in his Dashiji among major events around the transition from the Spring and Autumn to the Warring States periods, treating them as important stages in Qin's rise.

Ming and Qing Periods

• The Ming scholar Dong Shuo cited the establishment of Pinyang County and construction of Nanzheng during Duke Ligong's reign in Qiguo Kao as evidence for Qin's early county system and fortified urban construction.
• The Qing scholar Liang Yusheng systematically reviewed variant writings such as Duke Ligong, Duke Ligong, and Duke Ligong in Shiji Zhiyi, concluding that Duke Ligong was the conventional form and that his personal name may have been La.
• The Qing scholar Gu Donggao included changes to Qin's western boundaries during Duke Ligong's reign in the territorial tables of his Chunqiu Dashibiao, paying particular attention to the effects of the campaigns against Dali and Yiqu on Qin territory.

Modern Period

• Ma Feibai's Collected History of Qin treats Duke Ligong as an important Qin ruler and assembles his activities in detail, arguing that Qin's military victories over the western Rong during his reign laid foundations for later expansion in the periods of Duke Mu of Qin and Duke Xiao of Qin.
• Lin Jianming's Draft History of Qin argues that Qin's acceptance of surviving members of the Zhi clan, marriage alliance with Yue, and alliance with Chu during Duke Ligong's reign show the state's active response to political change around the Spring and Autumn–Warring States transition.
• Yang Kuan's History of the Warring States mentions Qin involvement in Jin affairs during Duke Ligong's reign while discussing interstate conditions around the Partition of Jin and regards the flight of Zhi clansmen to Qin as an important episode in Qin-Jin relations.
