The State of Qin (Chinese: 秦国; Chinese: 秦國; pinyin: Qín Guó; Wade–Giles: Ch'in Kuo) (778 BC–207 BC) was a Chinese feudal state that existed during the Spring and Autumn and Warring States Periods of Chinese history. It emerged as one of the dominant superpowers of the Seven Warring States by the 3rd century BC and eventually unified China under its rule in 221 BC, after which it is referred to as the Qin Dynasty.

Early history

Legendary origins and founding of Qin

According to the 2nd century BC historical text Records of the Grand Historian by Sima Qian, the Qin state traced its origin to Zhuanxu, one of the Five Emperors in ancient times. Dafei, an ancestor of the royal clan of Qin, helped Yu the Great in educating the people on flood control techniques, and was granted the family name of "Ying" (Chinese: 嬴) by Shun.

During the Xia and Shang dynasties, the Ying clan split into two branches:

• an occidental one, who lived in Quanqiu (犬丘; near present-day Tianshui on the upper valley of the Wei River
• an oriental one, who lived east of the Yellow River and became the ancestors of the rulers of the Zhao state

The occidental Ying clan was first ennobled in the beginning of the 9th century BC. Feizi of Qin served King Xiao of Zhou as a royal horse trainer and breeder, and was rewarded for his efforts with a fief in Quanqiu (present-day Tianshui, Gansu province) and a marriage to a princess. Feizi's territory was named "Qin" and was surrounded by lands belonging to the minority Rong people. Qin was frequently attacked by the Rong in the 9th century BC as relations between the Rong and the Western Zhou Dynasty worsened.

In 771 BC, Marquess of Shen formed an alliance with the Zeng state and Quanrong nomads, and they attacked and conquered the Western Zhou capital city of Haojing (鎬京; near present-day Xi'an, Shaanxi province). Xiang of Qin led his troops to protect King Ping of Zhou as the king led his men on an eastward retreat to Luoyang, where the new capital city of the Eastern Zhou Dynasty was established. In recognition of Xiang's efforts, King Ping promoted him to the rank of a Bo (伯; equivalent of a count), the third rank of nobility after Gong (公; Duke) and Hou (侯; Marquis) and promised that all the former lands of Zhou that were captured by the Rong people would become part of Qin's territories if Qin succeeded in retaking them. The future generations of the Qin rulers were encouraged by this promise, and they launched several military campaigns on the Rong, eventually expanding their territories to beyond the original lands lost by the Western Zhou Dynasty.

Ascendancy during the Spring and Autumn Period

Qin's interaction with other feudal states in eastern and central China remained minimal throughout the Spring and Autumn Period (722-481 BC), except with its neighbour Jin. Qin maintained good diplomatic relations with Jin and there were also marriages between members of the royal clans of both states, but relations between both sides had also deteriorated to the point of armed conflict before. During the early reign of Duke Mu of Qin, the Jin state was a formidable power under the leadership of Duke Xian of Jin. However, after the death of Duke Xian, Jin plunged into a state of internal conflict as Duke Xian's sons fought over the succession. One of them won the contention and became Duke Hui of Jin, but Jin was struck by a famine not long later and Duke Hui requested aid from Qin. Duke Mu of Qin sent relief food supplies and agricultural equipment to Jin. However, Qin was struck by famine later and by then, Jin had recovered and it turned to attack Qin. Qin and Jin engaged in several battles over the next few years.

During the battles with Jin, Duke Mu heard that one of Duke Xian's sons, Chong'er, was in exile in the Chu state. After consulting his subjects, Duke Mu sent an emissary to Chu to invite Chong'er to Jin, and Qin helped Chong'er defeat Duke Hui and Chong'er became the new ruler of Jin, with his title as "Duke Wen". Duke Wen was grateful to Duke Mu and relations between Qin and Jin improved. Qin used the opportunity when its eastern front was stable, to launch military campaigns against the minority tribes in the west. In 627 BC, Duke Mu of Qin planned a secret attack on the Zheng state, but the Qin army retreated after being tricked into believing that Zheng was prepared for Qin's invasion. Duke Wen had died and his successor, Duke Xiang of Jin, ordered his troops to lay an ambush for the retreating Qin army. The Qin forces were defeated in the ambush at the Battle of Yao (殽; near present-day Luoning County, Henan province) by Jin and suffered heavy casualties. Three years later, Qin attacked Jin for revenge and scored a major victory. Duke Mu refused to advance east further after holding a funeral service for those killed in action at the Battle of Yao, and focused on the traditional policy of expanding Qin's borders in the west. Duke Mu's achievements in the western campaigns and his handling of foreign relations with Jin earned him a position among the Five Hegemons of the Spring and Autumn Period.

Decline in the early Warring States Period

During the early Warring States Period, as its neighbours in east and central China began rapidly developing, Qin was still in a state of underdevelopment and decline. The population of Qin comprised a large proportion of Sinicized semi-tribal peoples, believed to be descendants of the Rong. This was believed to be a major cause of distinct unease and discrimination towards Qin from other states. The Wei state, formed from the Partition of Jin, became the most powerful state on Qin's eastern border. Qin was equipped with natural defenses, with Hangu Pass (函谷關; northeast of present-day Lingbao, Henan province) in the east and Tong Pass (潼關; present-day Tongguan County, Shaanxi province) in the west. Between 413 and 409 BC during the reign of Duke Jian of Qin, the Wei army led by Wu Qi, with support from Zhao and Han, attacked Qin and conquered Qin territories west of the Yellow River.

Reformation

Despite suffering losses in the battles with rival states such as Wei, the Qin rulers were actively pursuing reforms to the legal, economic and social systems of Qin. When Duke Xiao came to the throne of Qin, he issued an announcement, calling forth men of talent (including scholars, administrators, theorists and militarists) from other states to enter Qin and help him with his reforms, promising rewards of high offices and lands in return. Among these foreign talents, Wei Yang (later renamed to Shang Yang), a scholar from the Legalist School, successfully conducted a series of reforms in Qin with the support of Duke Xiao, despite facing strong opposition from several Qin politicians. The aristocracy system was abolished, with all slaves granted citizenship rights. People were forced to resettle in new clusters, where they focused on increasing agricultural output. Meritocracy was practised in the military, with soldiers and officers receiving due rewards according to their contributions, regardless of their backgrounds. However, tough and strict laws were imposed as well, with draconian punishments being meted out for the slightest of offenses, and even nobles and royals were not spared. After decades, the reforms strengthened Qin economically and militarily and transformed it into a highly centralized state with an efficient administrative system.

After Duke Xiao's death, King Huiwen became the new ruler of Qin and he put Shang Yang to death on charges of treason, but some believed that the king harboured a personal grudge against Shang because he was harshly punished under Shang's reformed system in his adolescence for a minor infraction. However, King Huiwen and his successors retained the reformed systems and they helped to lay the foundation for Qin's eventual unification of China under the Qin Dynasty in 221 BC. Shang Yang's theories were further elaborated later by Han Fei, who combined Shang's ideas with those of Shen Buhai and Shen Dao, that would form the core of the philosophies of Legalism. Qin rose to prominence in the late 3rd century BC after the reforms and emerged as one of the dominant superpowers of the Seven Warring States.

Effects of the successful Qin reforms

Qin's power continued growing in the following century after Shang Yang's reform, owing the success to the industriousness of its people. The Qin kings authorized many state development projects, including large public works such as irrigation canals and defensive structures.

One of the most obvious results of the reforms was the change in Qin's military. Previously, the army was under the control of Qin's nobles and comprised feudal levies. After Shang Yang's reforms, the aristocracy system was abolished and replaced by one based on meritocracy, in which ordinary citizens had equal opportunities as the nobles to be promoted to high ranks. In addition, military discipline was strongly enforced and the troops were trained to adapt better to different battle situations. Qin's military strength increased largely with the full support of the state. In 318 BC, the states of Wei, Zhao, Han, Yan and Chu formed an alliance and attacked Qin, but did not manage to advance beyond Hangu Pass, and were defeated by counter-attacking Qin forces. The alliance crumbled due to mistrust and suspicion and lack of coordination among the five states.

Apart from the effects on Qin's military, Shang Yang's reforms also increased labour for numerous public works projects aimed at boosting agriculture, and made it possible for Qin to maintain and supply an active military force of more than a million troops. This feat could not be accomplished by any other state, except Chu, during that time. Qin's conquests of the southern states of Ba and Shu in present-day Sichuan province also provided Qin with major strategic advantages. The lands in the new territories were very fertile, and helped serve as a "backyard" for supplies and additional manpower. It was hard for Qin's rivals to attack Ba and Shu, since the territories were located deep in the mountains upstream of the Yangtze River. At the same time, Qin's strategic position in Ba and Shu provided it with a platform for launching attacks on the Chu state, which lies downstream of the Yangtze.

Ascendancy and conquests during the Warring States Period

Wars against Chu, Han and Wei

During the reign of King Huiwen of Qin, the Chu state, to the southeast of Qin, became a target for Qin's aggression. Although Chu had the largest operationally-ready army of all the Seven Warring States at over a million troops, its administrative and military strength was plagued by corruption and divided among the nobles. Zhang Yi, a Qin strategist, suggested to King Huiwen to exercise Qin's interest at the expense of Chu. Over the following years, Zhang engineered and executed a number of diplomatic plots against Chu, supported by the constant military raids on Chu's northwestern border. Chu suffered many defeats in battles against Qin and was forced to cede territories to Qin. King Huai I of Chu was furious and ordered a military campaign against Qin, but he was tricked by Zhang Yi into breaking diplomatic ties with his allies, and his angered allies joined Qin in inflicting a crushing defeat on Chu. In 299 BC, King Huai I was tricked into attending a diplomatic conference in Qin, where he was captured and held hostage until his death. In the meantime, Qin launched several attacks on Chu and eventually sacked the Chu capital city of Chen (陳; present-day Jiangling County, Hubei province). The crown prince of Chu fled east and was crowned King Qingxiang of Chu in the new capital city of Shouchun (壽春; present-day Shou County, Anhui province).

In the next five decades after King Huiwen's death, King Zhaoxiang of Qin shifted his attention to northern China after Qin's victories in the south against Chu. In the early years of King Zhaoxiang's reign, the Marquis of Rang (穰侯) served as Qin's chancellor and he actively pushed for military campaigns against the Qi state in the far eastern part of China. However, the marquis had his personal motives, as he intended to use Qin's powerful military to help him conquer a fief in Qi territories, since the lands were not directly linked to Qin and would not be under the Qin government's direct administration.

Subsequently, King Zhaoxiang's foreign advisor, Fan Sui, advised the king to abandon those fruitless campaigns against distant states. King Zhaoxiang heeded Fan's advice and changed Qin's foreign policy to adopting good diplomatic relations with distant states (Yan and Qi), while concentrating on attacking nearby states (Zhao, Han and Wei). As a consequence, Qin began to launch constant attacks on Han and Wei over the next decades, conquering several territories in its campaigns. By then, Qin's territories had expanded to beyond the eastern shore of the Yellow River and Han and Wei were reduced to the status of "buffers" from Qin for the other states in the east.

Wars against Zhao

Main article: Battle of Changping

Starting from 265 BC, Qin launched a massive invasion on Han and forced Han to cede its territory of Shangdang (上黨; in present-day Shanxi province). However, Han offered Shangdang to Zhao instead, which led to a conflict between Qin and Zhao for control of Shangdang. Qin and Zhao engaged in the three-year long Battle of Changping, followed by another three-year siege by Qin on Zhao's capital city of Handan. The conflict at Changping was deemed as a power struggle, as both sides pitted their forces against each other not only on the battlefield, but also in the domestic context. Although Qin had an abundance of resources and vast manpower, it had to enlist every man above the age of 15 for war-related duties, ranging from front-line service to logistics and agriculture. King Zhaoxiang of Qin even personally directed his army's supply lines. The extent of mobilization and the exhaustion in the aftermath was not seen in world history for another 2,000 years, until this concept of total war re-entered the stage during World War I.^{[citation needed]} Qin's eventual victory in 260 BC was attributed to its use of schemes to stir up internal conflict in Zhao, which led to the replacement of Zhao's military leaders.

Following the Qin victory at the Battle of Changping, the Qin commander Bai Qi ordered the 400,000 prisoners-of-war from Zhao to be executed by burying alive. Subsequently, the Qin forces marched on the Zhao capital city of Handan in an attempt to conquer Zhao completely. However, the Qin troops were unable to capture Handan as they were already exhausted and also because the Zhao forces put up fierce resistance. King Xiaocheng of Zhao offered six cities to Qin as a peace offer and King Zhaoxiang of Qin accepted the offer after being persuaded by Fan Sui. Within Zhao, many officials strongly opposed King Xiaocheng's decision to give up the cities and subsequent delays caused the siege on Handan to be prolonged until 258 BC. Meanwhile, Bai Qi was consecutively replaced by Wang Xi, Wang Ling and Zheng Anping as the Qin commander at the siege.

In 257 BC, Qin was still unable to penetrate Handan after besieging it for three years, and Zhao requested aid from the neighbouring states of Wei and Chu. Wei was hesitant to help Qin initially, but launched an attack on Qin after seeing that Qin was already exhausted after years of war. The Qin forces crumbled and retreated and Zheng Anping surrendered. The combined forces of Wei and Chu continued to pursue the retreating Qin army and Wei managed to retake part of its original lands that were lost to Qin earlier.

Qin's irrigation projects

In the middle of the 3rd century BC, Zheng Guo, a hydraulic engineer from the Han state, was sent to Qin to advise King Zhaoxiang of Qin on constructing irrigation canals. Qin had a penchant for building large-scale canals, as evident from its Min River irrigation system. King Zhaoxiang approved Zheng Guo's idea on constructing an even bigger canal. The project was completed in 264 BC and the canal was named after Zheng. Qin benefitted from the project as it became one of the most fertile states in China due to the good irrigation system, and also because it could now raise more troops as a consequence of increased agricultural yield.

Conquest of the six states and unification of China

Main article: Qin's wars of unification

In 247 BC, the 13-year-old Ying Zheng became king of Qin after the sudden death of King Zhuangxiang. However, Ying Zheng did not wield state power fully in his hands until 238 BC, after eliminating his political rivals Lü Buwei and Lao Ai. Ying formulated a plan for conquering the other six states and unifying China with help from Li Si and Wei Liao.

In 230 BC, Qin attacked Han, the weakest of the Seven Warring States, and succeeded in conquering Han within a year. Since 236 BC, Qin had been launching several assaults on Zhao, which had been devastated by its calamitous defeat at the Battle of Changping three decades ago. Although Qin faced strong resistance from the Zhao forces, led by general Li Mu, it still managed to defeat the Zhao army by using a ploy to sow discord between King Qian of Zhao and Li Mu, causing King Qian to order Li Mu's execution and replace Li with the less competent Zhao Cong. Zhao eventually fell to Qin in 228 BC after the capital city of Handan was taken. However, a Zhao noble managed to escape with remnant forces and proclaim himself king in Dai. Dai fell to Qin six years later.

After the fall of Zhao, Qin turned its attention towards Yan. Crown Prince Dan of Yan sent Jing Ke to assassinate Ying Zheng but the assassination attempt failed and Qin used that as an excuse to attack Yan. Yan lost to Qin at a battle on the eastern bank of the Yi River in 226 BC and King Xi of Yan fled with remnant forces to Liaodong. Qin attacked Yan again in 222 BC and annexed Yan completely. In 225 BC, the Qin army led by Wang Ben invaded Wei and besieged Wei's capital city of Daliang for three months. Wang directed the waters from the Yellow River and the Hong Canal to flood Daliang and King Jia of Wei surrendered and Wei was conquered.

In 224 BC, Qin prepared for an attack on Chu, its most powerful rival among the six states. During a discussion between Ying Zheng and his subjects, the veteran general Wang Jian claimed that the invasion force needed to be at least 600,000 strong, but the younger general Li Xin thought that 200,000 men would be sufficient. Ying Zheng put Li Xin in command of the Qin army to attack Chu. The Chu defenders, led by Xiang Yan, took Li Xin's army by surprise and defeated the Qin invaders. The defeat was deemed as the greatest setback for Qin in its wars to unify China. Ying Zheng put Wang Jian in command of the 600,000 strong army as he had requested and ordered Wang to lead another attack on Chu. Wang scored a major victory against the Chu forces in 224 BC and Xiang Yan was killed in action. The following year, Qin pushed on and captured Chu's capital city of Shouchun, bringing an end to Chu's existence. In 222 BC, the Qin army advanced southward and annexed the Wuyue region (covering present-day Zhejiang and Jiangsu provinces).

By 221 BC, Qi was the only rival state left. Qin advanced into the heartland of Qi via a southern detour, avoiding direct confrontation with the Qi forces on Qi's western border and arrived at Qi's capital city of Linzi swiftly. The Qi forces were taken by surprise and surrendered without putting up resistance. Following the fall of Qi in 221 BC, China was unified under the rule of Qin. Ying Zheng declared himself "Qin Shi Huang" (meaning "First Emperor of Qin") and founded the Qin Dynasty, becoming the first sovereign ruler of a united China.

Culture and society

Before Qin unified China, each state had its own customs and culture. According to the Tribute of Yu, composed in the fourth century BC, there were nine distinct cultural regions of China, described in detail in the work. The work focuses on the travels of the titular sage, Yu Gong, throughout each of the regions. Other texts, predominantly military, also discussed these cultural variations.^[1]

One of these texts was Master Wu, written in response to a query by Marquis Wu of Wei on how to cope with the other states. Wu Qi, the author of the work, declared that the government and nature of the people were reflective of the terrain they live in. Of Qin, he said:

Qin's nature is strong. Its terrain is harsh. Its government is strict. Its rewards and punishments are reliable. Its people are unyielding and belligerent. Therefore, they scatter and fight as individuals. As the way to attack them, one must first entice them with profit and lead them away. Their officers are greedy for gain and will betray their generals. Take advantage of their separation to attack them when scattered, set traps and seize the key moment, then their generals can be captured.

—Wuzi, Master Wu

According to Wu, the nature of the people is a result of the government, which is in turn a result of the roughness of the terrain. Each of the states is expounded upon by Wu in this manner.^[2]

In his Petition against driving away foreigners (諫逐客書), Li Si mentioned that guzheng and percussion instruments made of pottery and tiles were the characteristics of Qin music.
