Spring and Autumn period

Early Spring and Autumn (771–685 BCE)

Court moves east (771)

After the Zhou capital was sacked by the Marquess of Shen and the Quanrong barbarians, the Zhou moved the capital east from the now desolated Zongzhou in Haojing near modern Xi'an to Wangcheng in the Yellow River Valley. The Zhou royalty was then closer to its main supporters, particularly Jin, and Zheng; the Zhou royal family had much weaker authority and relied on lords from these vassal states for protection, especially during their flight to the eastern capital. In Chengzhou, Prince Yijiu was crowned by his supporters as King Ping. However, with the Zhou domain greatly reduced to Chengzhou and nearby areas, the court could no longer support the six army groups it had in the past; Zhou kings had to request help from powerful vassal states for protection from raids and for resolution of internal power struggles. The Zhou court would never regain its original authority; instead, it was relegated to being merely a figurehead of the regional states and ritual leader of the Ji clan ancestral temple. Though the king retained the Mandate of Heaven, the title held little actual power.

With the decline of Zhou power, the Yellow River drainage basin was divided into hundreds of small, autonomous states, most of them consisting of a single city, though a handful of multi-city states, particularly those on the periphery, had power and opportunity to expand outward. A total of 148 states are mentioned in the chronicles for this period, 128 of which were absorbed by the four largest states by the end of the period.

Shortly after the royal court's move to Chengzhou, a hierarchical alliance system arose where the Zhou king would give the title of hegemon (霸) to the leader of the state with the most powerful military; the hegemon was obligated to protect both the weaker Zhou states and the Zhou royalty from the intruding non-Zhou peoples: the Northern Di, the Southern Man, the Eastern Yi and the Western Rong. This political framework retained the fēngjiàn power structure, though interstate and intrastate conflict often led to declining regard for clan customs, respect for the Ji family, and solidarity with other Zhou peoples. The king's prestige legitimized the military leaders of the states, and helped mobilize collective defense of Zhou territory against "barbarians".

Over the next two centuries, the four most powerful states—Qin, Jin, Qi and Chu—struggled for power. These multi-city states often used the pretext of aid and protection to intervene and gain suzerainty over the smaller states. During this rapid expansion, interstate relations alternated between low-level warfare and complex diplomacy.

Zheng falls out with the court (722–685)

Duke Yin of Lu ascended the throne in 722. From this year on, the state of Lu kept an official chronicle, the Spring and Autumn Annals, which along with its commentaries is the standard source for the Spring and Autumn period. Corresponding chronicles are known to have existed in other states as well, but all but the Lu chronicle have been lost.

In 717, Duke Zhuang of Zheng went to the capital for an audience with King Huan. During the encounter the duke felt he was not treated with the respect and etiquette which would have been appropriate, given that Zheng was now the chief protector of the capital. In 715, Zheng also became involved in a border dispute with Lu regarding the Fields of Xu. The fields had been put in the care of Lu by the king for the exclusive purpose of producing royal sacrifices for the sacred Mount Tai. For Zheng to regard the fields as just any other piece of land was an insult to the court.

By 707, relations had soured enough that the king launched a punitive expedition against Zheng. The duke counterattacked and raided Zhou territory, defeating the royal forces in the Battle of Xuge and injuring the king himself. Zheng was the first vassal to openly defy the king, kicking off the centuries of warfare without respect for the old traditions which would characterize the period.

The display of Zheng's martial strength was effective until succession problems after Zhuang's death in 701 weakened the state.

In 692, there was a failed assassination attempt against King Zhuang, orchestrated by elements at court.

The Five Hegemons (685–591 BCE)

Hegemony of Qi (685–643)

The first hegemon was Duke Huan of Qi (r. 685–643). With the help of his prime minister, Guan Zhong, Duke Huan reformed Qi to centralize its power structure. The state consisted of 15 "townships" (縣) with the duke and two senior ministers each in charge of five; military functions were also united with civil ones. These and related reforms provided the state, already powerful from control of trade crossroads, with a greater ability to mobilize resources than the more loosely organized states.

By 667, Qi had clearly shown its economic and military predominance, and Duke Huan assembled the leaders of Lu, Song, Chen and Zheng, who elected him as their leader. Soon after, King Hui of Zhou conferred the title of bà (hegemon), giving Duke Huan royal authority in military ventures. An important basis for justifying Qi's dominance over the other states was presented in the slogan 'Revere the King, Expel the Barbarians' (尊王攘夷; zun wang rang yi). The role of subsequent hegemons would also be framed in this way: as the primary defender and supporter of nominal Zhou authority and the existing order. Using this authority, during the first eleven years of his hegemony, Duke Huan intervened in a power struggle in Lu; protected Yan from encroaching Western Rong nomads; drove off Northern Di nomads after their invasions of Wey and Xing, providing the people with provisions and protective garrison units; and led an alliance of eight states to conquer Cai and thereby block the northward expansion of Chu.

At his death in 643, five of Duke Huan's sons contended for the throne, badly weakening the state so that it was no longer regarded as the hegemon. For nearly ten years, no ruler held the title.

Hegemony of Song (643–637)

Duke Xiang of Song attempted to claim the hegemony in the wake of Qi's decline, perhaps driven by a desire to restore the Shang dynasty from which Song had descended. He hosted peace conferences in the same style as Qi had done, and conducted aggressive military campaigns against his rivals. Duke Xiang's ambitions met their end when, against the advice of his staff, he attacked the much larger state of Chu. The Song forces were defeated at the battle of Hong (泓) in 638, and the duke himself died in the following year from an injury sustained in the battle. After Xiang's death his successors adopted a more modest foreign policy, better suited to the country's small size.

As Duke Xiang was never officially recognized as hegemon by the King of Zhou, not all sources list him as one of the Five Hegemons.

Hegemony of Jin (636–628)

When Duke Wen of Jin came to power in 636 after extensive peregrinations in exile, he capitalized on the reforms of his father, Duke Xian (r. 676–651), who had centralized the state, killed off relatives who might threaten his authority, conquered sixteen smaller states, and even absorbed some Rong and Di peoples to make Jin much more powerful than it had been previously. When he assisted King Xiang in a succession struggle in 635, the king awarded Jin with strategically valuable territory near Chengzhou.

Duke Wen then used his growing power to coordinate a military response with Qi, Qin and Song against Chu, which had begun encroaching northward after the death of Duke Huán of Qi. With a decisive Chu loss at the Battle of Chengpu in 632, Duke Wen's loyalty to the Zhou king was rewarded at an interstate conference when King Xīang awarded him the title of bà.

After the death of Duke Wen in 628, a growing tension manifested in interstate violence that turned smaller states, particularly those at the border between Jin and Chu, into sites of constant warfare; Qi and Qin also engaged in numerous interstate skirmishes with Jin or its allies to boost their own power.

Hegemony of Qin (628–621)

Duke Mu of Qin ascended the throne in 659 and forged an alliance with Jin by marrying his daughter to Duke Wen. In 624, he established hegemony over the western Rong barbarians and became the most powerful lord of the time. However he did not chair any alliance with other states nor was he officially recognized as hegemon by the king. Therefore, not all sources accept him as one of the Five Hegemons.

Hegemony of Chu (613–591)

King Zhuang of Chu expanded the borders of Chu well north of the Yangtze River, threatening the Central States in modern Henan. At one point the Chu forces advanced to just outside the royal capital of Chengzhou, upon which King Zhuang sent a messenger to inquire into the heft and bulk of the Nine Cauldrons – the symbols of royal ritual authority – implying he might soon arrange to have them moved to his own capital. In the end the Zhou capital was spared, and Chu shifted focus to harassing the nearby state of Zheng. The once-hegemon state of Jin intervened to rescue Zheng from the Chu invaders but were resolutely defeated, which marks the ascension of Chu as the dominant state of the time.

Despite his de facto hegemony, King Zhuang's self-proclaimed title of "king" was never recognized by the Zhou states. In the Spring and Autumn Annals he is defiantly referred to as Zi (子, "viscount"), even at a time when he dominated most of south China. Later historians however always include him as one of the Five Hegemons.

Late Spring and Autumn (591–453 BCE)

The Six Ministers (588)

In addition to interstate conflict, internal conflicts between state leaders and local aristocrats also occurred. Eventually the dukes of Lu, Jin, Zheng, Wey and Qi would all become figureheads to powerful aristocratic families.

In the case of Jin, the shift happened in 588 when the army was split into six independent divisions, each dominated by a separate noble family: Zhi (智), Zhao (趙), Han (韓), Wei (魏), Fan (范) and Zhonghang (中行). The heads of the six families were conferred the titles of viscounts and made ministers, each heading one of the six departments of Zhou dynasty government. From this point on, historians refer to "The Six Ministers" as the true power brokers of Jin.

The same happened to Lu in 562, when the Three Huan divided the army into three parts and established their own separate spheres of influence. The heads of the three families were always among the department heads of Lu.

Rise of Wu (584)

Wu was a state in modern Jiangsu outside the Zhou cultural sphere, considered "barbarian", where the inhabitants sported short hair and tattoos and spoke an unintelligible language. Although its ruling house claimed to be a senior lineage in the Ji ancestral temple, Wu did not participate in the politics and wars of China until the last third of the Spring and Autumn period.

Their first documented interaction with the Spring and Autumn states was in 584, when a Wu force attacked the small border state of Tan (郯) causing some alarm in the various Chinese courts. Jin was quick to dispatch an ambassador to the court of the Wu king, Shoumeng. Jin promised to supply Wu with modern military technology and training in exchange for an alliance against Chu, a neighbour of Wu and Jin's nemesis in the struggle for hegemony. King Shoumeng accepted the offer, and Wu would continue to harass Chu for years to come.

Attempts at peace (579)

After a period of increasingly exhausting warfare, Qi, Qin, Jin and Chu met at a disarmament conference in 579 and agreed to declare a truce to limit their military strength. This peace did not last very long and it soon became apparent that the bà role had become outdated; the four major states had each acquired their own spheres of control and the notion of protecting Zhou territory had become less cogent as the control over (and the resulting cultural assimilation of) non-Zhou peoples, as well as Chu's control of some Zhou areas, further blurred an already vague distinction between Zhou and non-Zhou.

In addition, new aristocratic houses were founded with loyalties to powerful states, rather than directly to the Zhou kings, though this process slowed down by the end of the seventh century, possibly because territory available for expansion had been largely exhausted. The Zhou kings had also lost much of their prestige so that, when Duke Dao of Jin (r. 572–558) was recognized as bà, it carried much less meaning than it had before.

Hegemony of Wu (506–496)

In 506, King Helü ascended the throne of Wu. With the help of Wu Zixu and Sun Tzu, the author of The Art of War, he launched major offensives against the state of Chu. They prevailed in five battles, one of which was the Battle of Boju, and conquered the capital Ying. However, Chu managed to ask the state of Qin for help, and after being defeated by Qin, the vanguard general of Wu troops, Fugai, a younger brother of Helü, led a rebellion. After beating Fugai, Helü was forced to leave Chu. Fugai later retired to Chu and settled there. King Helü died during an invasion of Yue in 496. Some sources such as the Confucian text Bai Hu Tong list him as one of the Five Hegemons.

He was succeeded by his son King Fuchai of Wu, who nearly destroyed the Yue state, imprisoning King Goujian of Yue. Subsequently, Fuchai defeated Qi and extended Wu influence into central China.

In 499, the philosopher Confucius was made acting prime minister of Lu. He is traditionally (if improbably) considered the author or editor of the Spring and Autumn annals, from which much of the information for this period is drawn. After only two years he was forced to resign and spent many years wandering between different states before returning to Lu. After returning to Lu he did not resume a political career, preferring to teach. Tradition holds that it was in this time he edited or wrote the Five Classics, including the Spring and Autumn Annals.

Hegemony of Yue (496–465)

In 482, King Fuchai of Wu held an interstate conference to solidify his power base, but Yue captured the Wu capital. Fuchai rushed back but was besieged and died when the city fell in 473. Yue then concentrated on weaker neighbouring states, rather than the great powers to the north. With help from Wu's enemy Chu, Yue was able to be victorious after several decades of conflict. King Goujian destroyed and annexed Wu in 473, after which he was recognized as hegemon.

The Zuozhuan, Guoyu and Shiji provide almost no information about Goujian's subsequent reign or policies. What little is said is told from the perspective of other states, such as Duke Ai of Lu trying to enlist Yue's help in a coup against the Three Huan. Sima Qian notes that Goujian reigned on until his death, and that afterwards his descendants—for whom no biographical information is given—continued to rule for six generations before the state was finally absorbed into Chu during the Warring States period.

Partition of Jin

After the great age of Jin power, the Jin rulers began to lose authority over their ministerial lineages. A full-scale civil war between 497 and 453 ended with the elimination of most noble lines; the remaining aristocratic families divided Jin into three successor states: Han, Wei and Zhao. This is the last event recorded in the Zuozhuan.

With the absorption of most of the smaller states in the era, this partitioning left seven major states in the Zhou world: the three fragments of Jin, the three remaining great powers of Qin, Chu and Qi, and the weaker state of Yan (燕) near modern Beijing. The partition of Jin, along with the usurpation of Qi by Tian, marks the beginning of the Warring States period.

Interstate relations

Ancient sources such as the Zuo Zhuan and the eponymous Chunqiu record the various diplomatic activities, such as court visits paid by one ruler to another (朝; cháo), meetings of officials or nobles of different states (會; 会; huì), missions of friendly inquiries sent by the ruler of one state to another (聘; pìn), emissaries sent from one state to another (使; shǐ), and hunting parties attended by representatives of different states (狩; shou).

Because of Chu's non-Zhou origin, the state was considered semi-barbarian and its rulers—beginning with King Wu in 704 BCE—proclaimed themselves kings in their own right. Chu intrusion into Zhou territory was checked several times by the other states, particularly in the major battles of Chengpu (632 BCE), Bi (595 BCE) and Yanling (575 BCE), which restored the states of Chen and Cai.

Literature

Some version of the Five Classics existed in the Spring and Autumn period, as characters in the Zuozhuan and Analects frequently quote the Book of Poetry and Book of Documents. On the other hand, the Zuozhuan depicts some characters actually composing poems that would later be included in the received text of the Book of Poetry. In the Analects there are frequent references to "The Rites", but as Classical Chinese does not employ punctuation or any markup to distinguish book titles from regular nouns it is not possible to know if what is meant is the Etiquette and Ceremonial (known then as the Book of Rites) or just the concept of ritual in general. On the other hand, the existence of the Book of Changes is well-attested in the Zuozhuan, as multiple characters use it for divination and accurately quote the received text.

Sima Qian claims that it was Confucius who, towards the close of the Spring and Autumn period, edited the received versions of the Book of Poetry, Book of Documents and Book of Rites; wrote the "Ten Wings" commentary on the Book of Changes; and wrote the entirety of the Spring and Autumn Annals. This was long the predominant opinion in China, but modern scholarship considers it unlikely that all five classics could be the product of one man. The transmitted versions of these works all derive from the versions edited by Liu Xin in the century following Sima Qian.

While many philosophers such as Lao Tzu and Sun Tzu were active in the Spring and Autumn period, their ideas were probably not put into writing until the following Warring States period.

Aristocracy

While the aristocracy of the Western Zhou frequently interacted via the medium of the royal court, the collapse of central power at the end of the first half of the dynasty left in its wake hundreds of autonomous polities varying drastically in size and resources, nominally connected by bonds of cultural and ritual affiliation increasingly attenuated by the passage of time. Whole lineage groups moved around under socioeconomic stress, border groups not associated with the Zhou culture gained in power and sophistication, and the geopolitical situation demanded increased contact and communication.

Under this new regime, an emergent systematization of noble ranks took root. Where the Western Zhou had concerned itself with politics, the ancestral temples and legitimacy, in the Eastern Zhou politics came to the fore. Titles which had previously reflected lineage seniority took on purely political meanings. At the top of the bunch were Gong (公) and Hou (侯), favoured lineages of old with generally larger territories and greater resources and prestige at their disposal. The majority of rulers were of the middling but tiered grades Bo (伯) and Zi (子). The rulers of two polities maintained the title Nan (男). A 2012 survey found no difference in grade between Gong and Hou, or between Zi and Nan. Meanwhile, a new class of lower-tier aristocrats formed: the Shi (士), gentlemen too distantly related to the great houses to be born into a life of wielding power, but still part of the elite culture, aiming at upward social mobility, typically through the vector of officialdom.

One individual well attested in the process of fixing the ranks of rulers into a coherent scheme was Zichan of Zheng, who both submitted a memorial to the king of Chu informing him of the proposed new system in 538 BCE, and argued at a 529 BCE interstate conference that tributes should be graded based on rank, given the disparity in available resources.

Alongside this development, there was precedent of Zhou kings "upgrading" noble ranks as a reward for service to the throne, giving the recipients a bit more diplomatic prestige without costing the royal house any land. During the decline of the royal house, although real power was wrested from their grasp, their divine legitimacy was not brought into question, and even with the king reduced to something of a figurehead, his prestige remained supreme as Heaven's eldest son.

Archaeologically excavated primary sources and received literature agree to a high degree of systematization and stability in noble titles during the Eastern Zhou, indicating an actual historical process. A 2007 survey of bronze inscriptions from 31 states found only eight polities whose rulers used varying titles of nobility to describe themselves.

Important figures

The Five Hegemons (春秋五霸): With the royal house of Zhou lacking the military strength to defend itself, and with the various states experiencing tension and conflict, certain very powerful lords took the position of hegemon, ostensibly to uphold the house of Zhou and maintain the peace to the degree possible. They paid tribute to the royal court, and were owed tribute by the other rulers. Traditional history lists five hegemons during the Spring and Autumn period:

• Duke Huan of Qi (r. 685–643 BCE)
• Duke Xiang of Song (r. 650–637 BCE)
• Duke Wen of Jin (r. 636–628 BCE)
• Duke Mu of Qin (r. 659–621 BCE)
• King Zhuang of Chu (r. 613–591 BCE)
