Duke Xiao of Qin (; 381–338 BC), personal name Ying Quliang, was a duke of the state of Qin during the Eastern Zhou dynasty, reigning from 362 to 338 BC. Duke Xiao is best known for employing the Legalist statesman Shang Yang Harvard University reference page for a 2006 class called Moral Reasoning; includes a useful map from the state of Wei 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 362 BC at the age of 19, 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.Records of the Grand Historian, by Sima Qian, translated by Burton Watson, chapter "Basic Annals of Qin." Pub. Chinese University of Hong Kong (1993), pp. 23-24 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, Herbert Giles, Chinese Biographical Dictionary on Shang Yang (Wei Yang) militaristic state, which governed through tough and oppressive laws.

In 366 BC, the Qin armies defeated the allied forces from the states of Han and Wei at the Battle of Shimen.The Cambridge History of Ancient China (1999/2007), v. 1, p. 618 (ch. "Warring States Political History" by Mark Edward Lewis) The Qin soldiers and officers were promoted to higher ranks based on the number of enemy heads they collected during battle.The Cambridge History of Ancient China (1999/2007), v. 1, p. 612 (ch. "Warring States Political History" by Mark Edward Lewis) 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 (the area west of the southern section of the Yellow River between modern-day Shanxi and Shaanxi provinces). After ascending the throne, Duke Xian (Duke Xiao's father) worked to stabilize the borders and relocated the capital to Liyang (southeast of present-day Fuping County, Weinan, Shaanxi). 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 (modern Huazhou District, Weinan, Shaanxi) 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 (modern Hancheng, Shaanxi) 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 (zhongshuzi) 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 (《法经》) 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" (dào of the sage-kings), 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" (rule through benevolence), but again failed to gain the duke’s favor. A third time, he spoke of the "Way of the Hegemon" (realpolitik-style domination), 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 (垦草令) in 359 BC, considered the prelude to full-scale reform.Many historical records date the start of Shang Yang's reforms to 356 BC. However, the reform debates concluded earlier, and the Land Reclamation Order was already a concrete plan proposed by Shang Yang. See:
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 (左庶长, Left Assistant Chancellor) in 356 BC to carry out the first phase of comprehensive reforms.
The main measures included: reforming household registration, implementing the "mutual responsibility system" (连坐法), enforcing strict military laws, awarding military merit, abolishing hereditary privileges (世卿世禄), establishing a twenty-rank system of military nobility, encouraging agriculture and textile production, punishing private disputes, codifying laws into the Qin Legal Code (秦律), and promoting the nuclear family system.
These reforms began to strengthen Qin’s national power. In 358 BC, Qin defeated Han at Xishan (present-day west of Mount Xiong'er, Henan). In 357, King Xuan of Chu sent his right court minister Hei to marry Duke Xiao’s daughter and form an alliance with Qin. In 355, Duke Xiao held a summit with King Hui of Wei at Duping (modern-day Chengcheng County, Shaanxi), 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 BC 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, Marquis Zhao of Han visited Qin to conclude a truce. In 342, Duke Xiao sent Crown Prince Si (later King Huiwen of Qin) to lead 92 Western Rong tribes to pay tribute to King Xian of Zhou, symbolizing Qin's leadership in the west.
