Duke Xiao of Qin


Duke Xiao of Qin, personal name Ying Quliang, was a duke of the state of Qin during the Eastern Zhou dynasty, reigning from 361 to 338 BC. Duke Xiao is best known for employing the Legalist statesman Shang Yang from the state of Wey and authorizing him to conduct a series of ground-breaking political, military and economic reforms in Qin. Although the reforms were controversial and drew violent opposition from many Qin politicians, Duke Xiao supported Shang Yang fully and the reforms did help to transform Qin into a dominant superpower among the Seven Warring States.
Duke Xiao ascended to the throne of the Qin state in 361 BC at the age of 21, succeeding his father, Duke Xian. Duke Xiao was determined to restore the Qin state to its former glory as one of the Five Hegemons as it had been during the reign of his ancestor, Duke Mu. Hence, the duke sent out an announcement, calling for men of talent to aid him in strengthening Qin, promising them rewards of high offices and lands in return for their service. Wei Yang, later known as Shang Yang, was a scholar from the Legalist School who responded to the duke's call as he had been unsuccessful in attempting to start his career in other states.
Wei Yang was introduced to Duke Xiao by Jing Jian and had two audiences with the duke, during which he proposed ideas concerning governance based on the principles of Confucianism, Taoism and other schools of thought, but the duke was not impressed. During the third meeting, Wei proposed his ideas on strict governance, based on concepts from Legalism, and captured the duke's attention. Duke Xiao and Wei Yang had a discussion that lasted for three days and three nights, after which they drafted plans for reform. The plans were put into effect in 363 BC, although several Qin politicians objected strongly to the reforms. However, Duke Xiao supported Wei Yang fully and ensured that the reforms were implemented as planned.
The reforms caused ground-breaking changes in the Qin state and transformed it into a strict, controlling, militaristic state, which governed through tough and oppressive laws. Agriculture was expanded through forced migration to new regions, and citizens were rewarded or punished based on their military or agricultural achievements.
In 366 BC, the Qin armies defeated the allied forces from the states of Han and Wei at the Battle of Shimen. The Qin soldiers and officers were promoted to higher ranks based on the number of enemy heads they collected during battle. Qin pushed on to seize lands from Wei, which managed to survive only with the help of the state of Zhao, and Wei was drastically weakened by its losses and defeats.

Life

Succession

Duke Xiao of Qin was born on the 9th day of the first lunar month in the fourth year of Duke Xian's reign, corresponding to 6 December 382 BC on the Julian calendar. According to Records of the Grand Historian, Duke Xian died in the 24th year of his reign, and his son Duke Xiao ascended the throne at the age of 21.
Even before the birth of Duke Xiao, the state of Qin had suffered a prolonged period of political instability under four successive rulers—Duke Li, Duke Zao, Duke Jian, and Duke Chu. During this time, Qin's national strength was greatly diminished. Taking advantage of this turmoil, the state of Wei seized control of the Hexi region. After ascending the throne, Duke Xian worked to stabilize the borders and relocated the capital to Liyang. He launched multiple campaigns to reclaim the lost Hexi territory, but died before achieving this goal.

Talent Recruitment Edict

When Duke Xiao of Qin ascended the throne, he ruled concurrently with King Wei of Qi, King Xuan of Chu, King Hui of Wei, Marquis Wen of Yan, Marquis Zhao of Han, and Marquis Cheng of Zhao.
At that time, the six major states of the Warring States period had already formed east of the Yellow River and Mount Xiao, while over ten smaller states lay between the Huai and Si Rivers. The royal house of Zhou had become weak, and the various states were locked in warfare, conquering one another. Of the six powers, Chu and Wei shared borders with Qin. The state of Wei occupied Qin's former Hexi region and built defensive walls northward from Zheng along the Luo River. Chu occupied the Wuguan and Qianzhong regions, extending south from Hanzhong.
Isolated in the remote western region of Yongzhou, Qin was excluded from the diplomatic alliances of the Central Plains states and treated like a barbarian country.
Duke Xiao sought to restore the hegemony of Duke Mu of Qin. He extended benevolence, aided widows and orphans, recruited warriors, enforced merit-based rewards, and famously issued a public edict calling for talented individuals to present strategies for enriching and strengthening the state. The edict reads:
That same year, Duke Xiao launched two military campaigns: one eastward to besiege Shan City and one westward against the Western Rong, where the Rong King Gua was slain.
Taking advantage of Qin’s transition of power, the states of Zhao and Han jointly attacked Qin.
In 343 BC, King Xian of Zhou sent sacrificial meat to Qin as a symbol of acknowledgment.

Shang Yang's Reforms

Arrival in Qin

Shang Yang, originally from the state of Wei, served as an attendant to Prime Minister Gongshu Cuo. After Gongshu's death, Shang Yang learned of Duke Xiao's public edict seeking talented individuals and traveled to Qin, bringing with him The Canon of Law compiled by Li Kui. He was introduced to Duke Xiao through Jing Jian, the duke's favored minister.
In his first audience, Shang Yang promoted the doctrine of the "Way of the Emperor", but Duke Xiao dozed off during the conversation. Afterward, he criticized Shang Yang as arrogant and unworthy. Five days later, Shang Yang returned, advocating the "Way of the King", but again failed to gain the duke’s favor. A third time, he spoke of the "Way of the Hegemon", which the duke found agreeable but still did not act on. By this time, however, Shang Yang had discerned the ruler’s true political intentions.
Finally, in a fourth audience, Shang Yang laid out specific strategies to strengthen the state and enrich the nation. Duke Xiao was so engrossed in their discussion that he unconsciously moved his knees closer to Shang Yang as they spoke. The two conversed for days without fatigue. Jing Jian, puzzled by this change, asked Shang Yang what had happened. Shang Yang explained that Duke Xiao had no interest in abstract ideals that required generations to bear fruit; he desired swift success to dominate the realm in his own lifetime, and thus was drawn to pragmatic proposals.

Land Reclamation Order

Encouraged by Shang Yang, Duke Xiao of Qin decided to implement domestic reforms. However, these faced strong opposition from conservative nobles such as Gan Long and Du Zhi. After intense debates, Duke Xiao issued the Land Reclamation Order in 359 BCE, considered the prelude to full-scale reform.
The decree focused on stimulating agricultural production, suppressing commerce, reshaping social values to elevate the prestige of agriculture, curbing the privileges of nobles and officials, involving aristocrats in farm labor, unifying tax collection systems, and introducing other foundational policies.

First Phase of Reform

Following the success of the Land Reclamation Order, Duke Xiao appointed Shang Yang as zuo shuzhang in 356 BCE to carry out the first phase of comprehensive reforms.
The main measures included: reforming household registration, implementing the "mutual responsibility system", enforcing strict military laws, awarding military merit, abolishing hereditary privileges, establishing a twenty-rank system of military nobility, encouraging agriculture and textile production, punishing private disputes, codifying laws into the Qin Legal Code, and promoting the nuclear family system.
These reforms began to strengthen Qin’s national power. In 358 BCE, Qin defeated Han at Xishan. In 357 BCE, King Xuan of Chu sent his right court minister Hei to marry Duke Xiao’s daughter and form an alliance with Qin. In 355 BCE, Duke Xiao held a summit with King Hui of Wei at Duping, marking Qin’s re-entry into interstate diplomacy.

Second Phase of Reform

Xianyang, the new capital, was located in the Guanzhong Plain, north of a plateau and south of the Wei River, with access to the Yellow River and Hangu Pass via the Wei River corridor. To facilitate eastward expansion beyond Hangu Pass, Duke Xiao ordered the construction of the Jique Palace and a new capital in 350 BCE based on the urban models of Lu and Wei. In the following year, the capital was moved from Liyang to Xianyang, and the second phase of reforms was implemented.
The main policies included: eliminating the well-field system, introducing private land ownership and transfer rights, enforcing county-level administration, introducing poll taxes, standardizing weights and measures, burning private philosophical texts, promoting legal clarity, restricting influence from private clans, banning itinerant officials, and enforcing residential registration laws.
Following the reforms, Qin became wealthy and powerful. Citizens were prosperous, theft disappeared, and the countryside was peaceful. People were brave in public service but avoided private conflict. In recognition, King Xian of Zhou granted Duke Xiao the title of hegemon, and envoys from many states came to offer congratulations. In 348 BCE, Marquis Zhao of Han visited Qin to conclude a truce. In 342 BCE, Duke Xiao sent Crown Prince Si to lead 92 Western Rong tribes to pay tribute to King Xian of Zhou, symbolizing Qin's leadership in the west.

Hexi Campaign

The recovery of the Hexi region and the restoration of Duke Mu of Qin’s hegemony were longstanding goals of both Duke Xian and Duke Xiao of Qin. As early as Duke Xian’s reign, Qin and Wei had fought several battles over Hexi, with Qin emerging victorious at Luoyin, Mount Shimen, and Shaoliang. Following Shang Yang’s two rounds of reforms, Qin's national strength increased significantly, enabling it to reclaim the Hexi region.

Battle of Yuanli

In 354 BCE, the state of Zhao invaded Wei’s ally Wei, and seized Qī and Fuqiu. Wei intervened and laid siege to Zhao’s capital, Handan. Seizing the opportunity while Wei's main forces were away, Duke Xiao dispatched troops to attack the Wei stronghold at Yuanli, achieving a decisive victory by killing 7,000 Wei soldiers and occupying Shaoliang.
That same year, Duke Xiao ordered Gongsun Zhuang to attack Han and besiege Jiaocheng, though it was not taken. However, they occupied Shangzhi, Anling, and Shanshi, and fortified these cities, inserting Qin influence into the border region between Han and Wei.

Battle of Anyi and Guyang

In 353 BCE, Marquis Cheng of Zhao sent envoys to seek military assistance from Qi. King Wei of Qi responded by dispatching two armies. One joined with forces from Song under Jing Dui and from Wei under Gongsun Cang to besiege Xiangling, a Wei stronghold.
At the same time, Wei forces breached Handan, but were defeated by another Qi army led by Tian Ji and Sun Bin at the Battle of Guiling. Chu’s King Xuan also sent General Jing She to assist Zhao and seized territory between the Sui and Hui rivers.
In 352 BCE, taking advantage of Wei’s weakened interior, Duke Xiao appointed Shang Yang as Da Liang Zao and ordered a full invasion. Qin occupied the old Wei capital of Anyi.
To defend against Qin, King Hui of Wei ordered construction of a defensive wall east of Guyang in the Shang Commandery region, known as the Xiaoshan Great Wall. In 351 BCE, Shang Yang once again led troops to besiege and capture Guyang.

Alliance at Tongdi

Also in 352 BCE, King Hui of Wei, with assistance from Han, defeated the allied forces of Qi, Song, and Wei besieging Xiangling. Qi was forced to request Chu's General Jing She to mediate a truce.
In 351 BCE, King Hui and Marquis Cheng of Zhao concluded an alliance near the Zhang River, leading to the withdrawal of Wei troops from Handan. With peace restored with the other states, Wei concentrated its forces westward, recapturing Anyi and besieging Guyang again.
To buy time for domestic reforms, Duke Xiao held a peace summit with King Hui at Tongdi in 350 BCE, temporarily easing tensions.

Alliance at Fengze

King Hui of Wei, under the pretext of paying tribute to the Zhou King, summoned the Twelve Lords of Sishang to plan a coalition against Qin. In response, Duke Xiao adopted Shang Yang’s strategy of "honoring Wei as king" to alter its aggressive posture. In 344 BCE, Shang Yang traveled to Wei and advised King Hui that in addition to commanding smaller states like Song, Wei, Zou, and Lu, he should seek northern alliance with Yan, attack Qi in the east to subdue Zhao, ally with Qin in the west, and attack Chu in the south to subjugate Han—thus securing true hegemony.
Shang Yang also suggested that King Hui first claim the royal title to align with the will of the people. King Hui accepted this plan, proclaimed himself king, constructed grand palaces, and adopted royal insignia such as red robes and seven-star flags. He convened the Fengze Assembly, attended by Prince Shaoguan of Qin and Marquis Su of Zhao.
However, King Hui’s breach of ritual protocol angered Qi and Chu, and the other lords shifted allegiance toward Qi.

Battle of Western Border

In 343 BCE, Qin constructed a fortress at Wucheng.
In 341 BCE, Wei suffered a major defeat at the Battle of Maling by the State of Qi. General Pang Juan committed suicide, and Crown Prince Shen was captured. Seizing this opportunity, Shang Yang told Duke Xiao:
Duke Xiao accepted Shang Yang’s plan and launched a large-scale invasion.
In the same year, Qin allied with Qi and Zhao to attack Wei. In the ninth month, Duke Xiao sent Shang Yang to attack Wei’s Hedong region. Wei dispatched Prince Ang to resist. During a standoff, Shang Yang sent a letter to Ang:
Ang agreed, but during the meeting, Shang Yang ambushed and captured him. Taking advantage of the confusion, he launched a surprise attack and routed the Wei army. Weakened by defeats from Qi and Qin, King Hui of Wei was forced to cede part of the Hexi region to Qin in exchange for peace.
In recognition of his achievements, Shang Yang was enfeoffed with 15 towns in the regions of Yu and Shang, earning the title "Lord Shang."
In 338 BCE, Qin again attacked Wei, defeating its army at Anmen, and captured its general Wei Cuo. That same year, Qin allied with the Dali Rong to besiege He yang.

Death

In 338 BCE, Duke Xiao fell gravely ill. According to the Strategies of the Warring States, he intended to pass the throne to Shang Yang, who declined.
Five months later, Duke Xiao died and was buried at Di Yu. His son succeeded him as King Huiwen of Qin. Shang Yang, accused by Prince Qian of treason, was defeated and executed at Tongdi. His corpse was brought to Xianyang and dismembered by chariots as public punishment.

Legacy

Duke Xiao ruled Qin for 24 years and died at the age of 44 in 338 BC. He was succeeded by his son, King Huiwen of Qin. Duke Xiao was given the posthumous name of "Xiao", which means "filial". The reforms that took place during his reign helped to lay a strong foundation for Qin's eventual unification of China under the Qin dynasty, under the leadership of Duke Xiao's descendant, Zheng, who became Qin Shi Huang, the first emperor of China.
Duke Xiao was also the last ruler of Qin to be addressed as "duke", as his successors titled themselves "kings". This change reflected the loss of authority of the central government, the Zhou dynasty, and rulers of several other feudal states had begun to call themselves "kings" instead of "dukes" as well.
