From the Sui to the Tang

 Unification of China: The Sui Dynasty 589-618.

  • The middle of the 6th century there were only four main political units.
  • After the collapse of the Northern Wei the north was divided
  • a) between the Northern Zhou to the north west &
  • b) the more sanitized Northern Qi, to the north east.

  • On the middle of the Yangzi River was the small state of Liang.
  • South of the Yangzi valley there was the Chen empire.
  • The Chen was ruled by the last of the six dynasties.

  • The Northern  Zhou and the Northern Qi competed for the control of north China.
  • Their actions were limited by the threat of a new steppe confederation.
  • This confederation was headed bt the Tujue.
  • They were a Turkish people.
  • Their influence had spread  from Manchuria all t way to the border of Persia.

  • In 577 the Northern Zhou attacked and defeated the Northern Qi.
  • They did this with the help of the Chen state.
  • In 582 the Turkish empire split into a eastern and western part.
  • Now the threat from the north was reduced.
  • This allowed the Northern Zhou to overrun the Liang in 587.
  • Two years later they overwhelmed the Chen.


Yang Jian

  • Northern Zhou society was dominated by a group of non-Chinese aristocratic family.
  • One such family, the Yuwen, occupied the throne.
  • Yang Jian, a main player in these events came from another of these families. 
  • This was probably from Xianbei extraction.

  • Yang Jian hd been born and raised in a Buddhist temple.
  • His wife, who was a Buddhist, came from a prominent Xiongnu clan.
  • His daughter was married to the heir apparent.

  • Yang Jian rose to power as a military commander.
  • Yang Jian's son-in-law succeeded to the throne.
  • That was the year the Northern Zhou emperor died.
  • A year later Yang Jian got rid of him.
  • Then he tried to wipe out the entire Yuwen family which started a civil war.

  • Yang Jian, with the help of a military leader Gao Jiong, defeated his opponents.
  • He established a new dynasty to be known as the Sui.
  • Gao Jiong later became his long serving minister.
  • Thereafter Yang Jian is better known by his posthumous title, Wendi.


Emperor Wendi

  • Wendi insisted that he was the legitimate heir to the Han Dynasty.
  • He went through the proper rituals to confirm this.
  • It provided him with the moral justification for conquering the south.
  • He succeeded it in 589.

  • the city of Jiankang was sacked
  • Wendi won the allegiance of the Chen aristocrats and its officials 
  • this is because he treated them leniently
  • Wendi was determined to broaden the basis of his support
  • he did this by endorsing the virtue of filial-piety, thus pleasing the Confucianists.
  • at the same time he ended the persecution of Buddhism.
  • he began the construction of a great new capital at Chang’an 
  • he set out to reconstitute a central government with the same practices as the Han

  • under Wendi, more Chinese were employed in the service of the state
  • but the important offices were monopolized by his  close relatives
  • the positions in office also went to those who had held offices in Northern Zhou.

  • Wendi personally investigated the work of his officials when travelling
  • he also instituted two rules: 
  • a) an official could not work in his own district of origin
  • b) the length of time an official could hold a post was limited
  • these rules served as a device for the control of his officials.
  • Wendi did not admire scholars 
  • but in his reign the essential characteristics of the examination system took shape.

  • examinations were conducted by the Board of Civil Office
  • they were held three times a year
  • degrees were awarded at three levels.

  • for a lower degree one  had to show literary ability and knowledge of a classical work
  • the most prestigious award or degree, the xiucai, or “cultivating talent” 
  • this degree was for the candidate’s broader learning
  • successful candidates were appointed to official positions. 

Reforms

  • Wendi also put forth some important reforms in the areas of law and taxation.

  • he promulgated the Kaihuang Code
  • it defined crimes and their punishments in plain terms
  • it abolished some cruel punishments
  • the Kaihuang Code was to serve as a model for all future imperial legal codes.

  • Wendi also overhauled the land and taxation system
  • he did this by reviving the “equal field” arrangement.
  • the common people were required to pay three taxes:

  • a) a land tax payable in grain; 
  • b) a textile tax payable in silk or linen; 
  • c) a labour tax requiring 20 days labour per year from adult males.

  • Wendi reorganized the military under a central control.
  • he confiscated all the weapons after demilitarizing those of the North China Plain
  • he also gained control of Champa, known in modern times as Annam
  • in the north, he was able to contain & control  the Turks 
  • this was done by establishing military colonies and by building walls. 
  • for many of his actions Wendi had received the advice of his consort
  • such a role was accepted in northern aristocratic families
  • but was unique in China’s dynastic annals.
  • it was on her advice that the emperor’s second son was nominated heir.


Emperor Yangdi


  • the Yangdi emperor, as he was later known succeeded his father Wendi in 604.
  • due his father’s sound economic basis Yangdi issued large scale public work projects:

  • a) building of a 2nd capital at Luoyang (pop. 400,000 – 500, 000)
  • b) palaces along the canal routes & transportation hubs.
  • c) the Grand Canal
  • two aspects of Yangdi’s reign are often criticized: 
  • a) his program of canal-building
  • b) his fixation or obsession with the conquest of Korea.


  • he built the canal to enable the resources of the south to be brought to the north
  • the south was more productive in terms of agriculture and industries
  • this was done by connecting the drainage of the Yellow, Huai, and Yangzi rivers.

  • the program originally got started with Wendi and
  • in some areas it merely improved the existing waterways.

  • Yangdi created a network of four canals extending for about 1465 miles.
  • this was an engineering feat without parallel in the world of its time.
  • this system of communication provided the basis for the prosperity of the Tang period.
  • it was achieved by 
  • a) state intervention into the economy
  • drafting thousands of men ands women labourers
  • these are features which earned him condemnation by the Confucian historians
  • his foreign policy was shaped by his awareness of a possible major threat 
  • this was still posed by the eastern Turks in what is now Mongolia
  • this was the threat of an alliance between the Turks and the Koreans
  • his response was to continue his father’s strategy of 
  • a) building walls
  • b) using marriage diplomacy
  • seeking alliances with the potential enemies of the eastern Turks.

  • for this he sent out his frontier expert Pei Ju
  • in 607 the emperor Yangdi himself travelled to Yulin
  • he was angered when he discovered that an embassy from Koguryo
  • this was in eastern Manchuria and the northern part of the Korean peninsula.


Expeditions Against Korea

  • this threat of this alliance prompted his disastrous expeditions against Korea.

  • the first attack was launched in 612
  • at this time he was forced to withdraw because of 
  • a) poor planning 
  • b) strong resistance by the Koguryo
  • Yangdi had launched the attack himself with an armed force of more than 1.3 million.
  • further campaigns launched in 613 and 614 had similar results
  • during the 613 campaign Yangdi had to retreat 
  • this was because he had to deal with a rebellion
  • this rebellion was threatening Luoyang, the capital city.
  • his campaigns made him ignore social and economic consequences:
  • a) high cost in manpower
  • b) excessive levies
  • c) disruption of livelihood
  • d) great loss of life.

  • - the campaign had been done on the backs of a series of construction projects:
  • a) Luoyang
  • b  the Grand Canal, 
  • c  numerous palaces, 
  • d) the Great Wall.

  • Yangdi’s many supporters abandoned him
  • in 618 he was murdered by a descendent of the Yuwen family,
  • historians always attributed the collapse of the Sui to Yangdi on
  • a) his personal failings 
  • b) excessive ambition

  • the disastrous flooding of the Yellow River valley in 611 led to the rise of the rebellion.

  • the harsh conscriptions of peasants was his fault
  • the conscriptions were for canal-building and the military campaigns 

  • the collapse may be explained by 
  • a) the continual rivalry within the northern aristocratic clans
  • b) the survival of separatist sentiments in the territory of the former northern Qi
  • c)  the willingness of Li Yuan to reach a demeaning accommodation with the Turks.

The Establishment of the Tang

  • Li Yuan was a member of the northern aristocratic family
  • he was probably from a Hebei family intermarried with the Xianbei aristocracy. 

  • Li Yuan pursued a military career
  • under the Sui, his success in suppressing rebellion led to a promotion 
  • the promotion was to command the important garrison at Taiyuan.

  • it was at Taiyuan, that in 617 Li Yuan decided to start a debatable rebellion. 
  • the Sui looked like it was deteriorating
  • Yangdi had grown apprehensive concerning the danger of his throne being seized.
  • he had heard of as prophecy that the next ruler would have the surname Li
  • so, he ordered the execution of anyone having that surname.

  • Li Yuan, upon hearing this, took action
  • he had planned to take part in the revolt
  • the Turks who were promised the booty seized by the rebels 
  • the Turks were encouraged to believe that Li Yuan was willing to become their vassal. 

  • within one year of the rebellion, Li Yuan had captured Chang’an
  • he declared the establishment of the Tang dynasty.
  • Li Yuan was given the posthumous title of Gaozu.


The Reign of Gaozu

  • this was because of the multiplicity of rebellions and claims to the throne
  • so he needed extensive military campaigns to extinguish his rivals.
  • Gaozu had a tendency to win over rebel leaders and give Sui officials their posts.

  • the transfer of power did not imply any major shift in the place of power
  • Gaozu’s support came from the same northern aristocratic clans as that of the Sui.

  • Gaozu continued the Sui practices in central and local governments
  • he also maintained their legal and taxation system.

  • early in his reign Gaozu had appointed Fu Yi, as his astrologer
  • Fu Yi was a Daoist priest known as a fierce critic of Buddhism.

  • Gaozu declared that Daosim and Confucianism were key pillars of the state
  • to him Buddhism was a foreign religion
  • he noted that the monks were involved in worldly affairs
  • this contradicted the tenets of their beliefs.
  • Gaozu’s way of dealing with the Turks showed how fragile his position
  • he was forced to retain their goodwill through bribery
  • but he did manage to consolidate his position in China.
  • during his reign Gaozu brought about some changes: 

  • a) mints were established and a new currency was issued; 

  • b) a revised code of law was produced which went further than that of the Sui in incorporating features of southern practice;

  • c) he revived the examination system, although he continued to appoint aristocrats to senior positions;

  • d) he reduced the throne’s reliance on Buddhism as a unifying force.

  • then Gaozu’s reign came to a sudden end.



Li Shimin

  • Li Shimin, Gaozu’s son, was a bitter rival of his elder brother who was heir.
  • Li Shimin had played a major role in the military campaigns
  • these were the one that helped consolidate the Tang control in the east
  • by now had built up a strong personal following.
  •  the heir’s strength lay in the court and in the capital, Chang’an
  • in an atmosphere of intrigue and plots Li Shimin carried out a coup
  • the event known as the Xuanwu Gate incident
  • this resulted in 
  • a) the death of the heir, his older brother
  • b) the abdication of Gaozu
  • c) the succession of Li Shimin, henceforth to be known as Taizong.
