The Tang Dynasty is widely considered a cultural and political high point of imperial China. The dynasty was founded by Li Yuan, the Duke of Tang, when the threat of insurrection forced the previous Sui dynasty court to flee from Luoyang, the capital, to Yangzhou. Li Yuan marched to Luoyang and seized the abandoned capital in 618 CE. [1] He became the first emperor of the Tang dynasty (r. 618-626 CE) and is posthumously known as Gaozu. Under the Early Tang Dynasty, the capital was moved from Chang’an to Luoyang. [2] We divide the Dynasty into an Early period (618-763 CE) and Late period (763-907 CE), separated by the decline in imperial authority and instability of experienced by the Tang in the 750s, culminating in the An Lushan rebellion to close out the Early period (755‒763 CE).
The Tang Dynasty continued to rule China after the defeat of the An Lushan rebellion (755‒763 CE). [3] However, the government never fully recovered from its impact. [3] Tang border defences were devastated, leading to attacks from outsiders and pirates. The Tang government maintained an often-uneasy alliance with the Uighurs against the Tibetans. [4] In 790, Tibetan forces occupied Chinese land in eastern Turkestan and ended Chinese rule in the region for almost a thousand years. [5] [6]
Late Tang China was marked by conflict, with the occasional brief period of peace. Emperor Xianzong’s campaigns against rebel governors in the early 9th century restored almost all of China back to direct rule under the Tang government. [5] Xianzong was successful in restoring stability to the Tang Empire and his death was followed by 40 years of peace. [7] Later, Emperor Wuzong persecuted Buddhists and adherents of other non-indigenous religions. His movement reached its height in 845 CE and most monasteries were destroyed, but his successors reversed his anti-Buddhist policies. [8]
The dynasty fell in 881 CE after a series of internal rebellions, leading to about a century characterized by the rise of powerful warlords in the south and political turmoil in the north [9] before another period of Chinese efflorescence under the Northern Song Dynasty. [10]
Population and political organization
The Late Tang Dynasty was marked by tensions between the central government and military garrisons. [11] In 763 CE, two-thirds of the provincial governors were military commanders. [4] Tang emperors attempted to weaken the central bureaucracy by having military governors pay direct tribute instead of taxes. [12] The Tang government implemented the two-tax system in 780 CE, which replaced the ’equal land’ distribution system of the Early Tang. [13] This system of taxation represented an attempt to weaken military garrison governments and to divert taxation income to the central government. [13]
The Late Tang central government was marked by the rise of eunuchs. Eunuchs did not hold powerful positions in the Early Tang government, but in the later period the Department of the Inner Palace, staffed by eunuchs, became a powerful governmental authority ‒ more powerful than the emperor’s chief ministers. [14]
Because the dynasty was marked by almost constant conflict, the population of Late Tang China is difficult to estimate. In 766 CE there were between 40 million and 55 million citizens, [15] and in 900 CE there were between 60 million and 80 million. [16]

"After the foundation itself, the rebellion is without doubt the most significant event in the history of the dynasty. It transformed a centralized, rich, stable and far-flung empire into a struggling, insecure and divided one." [1]
"In a long and costly campaign the T’ang succeeded in crushing the rebellion by 763. An Lu-shan himself had been killed earlier, in 757, by his own son. The son was, in turn, slain by Shih Ssu-ming who was then commander of all the rebel armies. Shih Ssu-ming, whose military ability was undoubted, suffered an identical fate and was subsequently murdered by his own son. Although ultimately defeated, the An Lu-shan rebellion revealed fully all the inherent weaknesses of the T’ang government. In effect, it broke its power, and while the dynasty lasted almost another century and a half it never recovered fully, in spite of the attempts made by some of the subsequent T’ang rulers, as for example Emperor Hsien-tsung (806-820), to restore a strong, centralized monarchy." [2]
Toward the end of the dynasty "effective control passed to regional states formed from the independent provinces. When one of these, the Liang, usurped the throne, the dynasty came to an end." [3]

"It is impossible, however, to believe, as some authors would have it, that 36 million people perished, especially in view of the fact that large parts of the country were not affected by the fighting. It is more likely these figures reveal a far-reaching disorganization of the government and its inability to have a proper census carried out. The T’ang government never recovered full control, particularly in the northern provinces ... the areas under the rule of the more independent military governors failed to follow the instructions of the central government also in this respect as they did in so many others."

levels.
"Studies of Chinese urban history have pointed to a revolutionary change in urban settlement after the Rebellion. The change was conditioned by the rise of long-distance trade between the north and the south and the increase in rural markets across the country. Kaifeng is a well-known case. It was the first city in Chinese history to be chosen as the political centre because it was a hub of transport and trade." [1]
"In a general survey of urban development in China prior to 960, Shi Nianhai counted 21 large cities that performed a key role in inter- and intra-regional trade after the mid-Tang period." [1]

843 CE all Manichaean "temples were destroyed, their books burned, some of their priestesses slain, the religion proscribed and all their property consficated." by Taoist Emperor Wu-tsung (841-846 CE). [2]
845 CE Buddhists, Zoroastrians and Nestorians were persecuted by Taoist Emperor Wu-tsung (841-846 CE). "4600 temples and monastries, 40,000 smaller shrines were ordered to be destroyed; 260,000 monks and nuns were secularized; 150,000 temple slaves turned over to the state; all statues melted down and the metal confiscated and, what was most important, all the vast amount of land in the hands of the Buddhist establishment was taken over by the government." [3]
Under Emperor Hsuan-tsung (847-859 CE), who was a Buddhist, the persecution was lifted "but it never fully regained its position, wealth and prestige. Any possibility that it had of becoming a state church in the future was thus eliminated." [4]

levels.
1. Emperor
In this period: "Although they were formally ensconced on the throne... the T’ang emperors ruled only indirectly over much of the country. Real power became concentrated increasingly in the hands of the military governors; their number rose to fifty and in some regions the posts became hereditary." [1]
2. The Department of the Inner Palace (Nei-shih sheng)The Department of the Inner Palace (Nei-shih sheng), staffed by eunuchs, in this period became the most important authority of the imperial household. The eunuchs initially acted as intermediaries between the Emperor and the bureaucracy, later became directly involved in central government, provincial appointments, succession disputes. [2]
Is this the same thing as the "inner court (nei-t’ing)"? 820s/830s CE and last quarter of 9th century were the "high points of their political influence" [3]
_Central government_
Despite reputation of this period as one of loss of central government control, the diary of a Japanese Buddhist monk, Ennin, suggests to some degree otherwise. Quoting E. O. Reischauer: "The remarkable degree of centralized control still existing, the meticulous attention to written instructions from higher authorities, and the tremendous amount of paper work involved in even the smallest matters of administration are all the more striking just because this was a period of dynastic decline." [4]
"The activity of eunuchs in court politics was undoubtedly one of the distinguishing features of late T’ang history... their role in the first half of the dynasty had been very limited." [5]
2. Hall of Administrative Affairs / Chief Ministers’ office (from 723 CE)Three chief ministers also called "Hall of Administrative Affairs (Cheng-shih t’ang)" an informal advisory group. [6]
from 723 CE became an official government organ "with a separate budget and seal" Chief Ministers’ office (Chung-shu Men-hsia) [6]

[9]
6.The financial specialists who headed Salt and Iron Commission and Public Revenue Department of the Board of Finance: "In the post-rebellion period, they developed the rudiments of professional standards and self-esteem, were permitted to recruit subordinates outside the regular system, and introduced thereby a new career track into the administration, one that remained in existence through northern Sung times." [10]

2. Delegate of Court Assembly"Each prefecture (chou) sent a representative to a special assembly held in the presence of the emperor. While in the capital they were lodged in special quarters in the south-east part of the city. The assemblies were held on the fifteenth of the second, seventh and tenth moons. We know more about the function of the system under the T’ang, which held such assembles annually. The T’ang delegates were generally prefects or other ranking officials who were expected to bring to the capital their candidates for the official examinations plus tribute gifts for the emperor. An examination into the performance of the local officials in each local unit was held, and this was followed by an audience." [12]
_Provincial government_
"By 763 the provinces controlled by military (chieh-tu shih) and civil (kuan-ch’a shih) governors had formed a permanent tier of authority throughout the empire, interposed between central government and the old prefectures and counties. These provinces developed forms of autonomy and semi-autonomy..." [13]
2. Military governors"The T’ang government never recovered full control, particularly in the northern provinces ... the areas under the rule of the more independent military governors failed to follow the instructions of the central government..." [14]
"the military governors retained most of the revenue of the areas under their control for themselves." [1]
"The powerful decentralized provincial order which emerged in China after the middle of the eighth century was a direct result of the An Lu-shan rebellion of 755-63." [15]
chieh-tu shih commanded a fan- or fang-chen. "In addition to his military responsibilities the new military governor also held broad civil power over local administration, finance and supply." [16]
2. Circuits"The T’ang reconstructed the administration of the country by creating ten large circuits (later raised to fifteen)..." [7]
2. Civil inspecting commissioner (from 733 CE)ts’ai fang ch’u-chih shih "were appointed in each of the fifteen new provinces (tao) into which the empire was divided." [17]
3. Prefectures (chou)"the country was further divided into prefectures, chou (over 350) [7]
"Half a century after the rebellion central government still did not control the provinces effectively. Some of them, particularly in the north and east, were entirely autonomous; others, although administered by court-appointed officials, were only partially controlled from the centre." [18]
"The independent provinces still recognised Tang sovereignty and the semi-autonomous ones still accepted appointments made by central government." [19]
4. Counties (hsien)"and these in turn into around 1500 countries (hsien) [7]
"The really basic form of government, the only level with which the great majority of the population had any contact, was the county under the rule of a magistrate. This was also the lowest level at which the central bureaucracy functioned." [20]
5. Districts (hsiang)"while at the bottom were the districts (hsiang), around 16,000 in number. [7]

Professions
Professional Soldier:

"The fubing system had originally preserved the Chinese ideal of the farmer-soldier, but after the early Tang soldiers became increasingly a separate, professional class. By the tenth century, soldiers, to the intense consternation of statesmen, were wholly divorced from any productive activities and earned their livings by skill at arms. Despite many attempts to replace this "mercenary" system, it remained in place until the end of imperial times." [1]
"From 737 it was decided to replace the militia entirely with paid chien-erh regulars; they were recruited by calling for volunteers from the population in general." [2]

"It is a fact that from the T’ang period on an ever-increasing proportion of officials was recruited from successful candidates at the examinations, that most of the political leaders for the next thirteen centuries did pass the examinations and were thus chosen on grounds of intellectual talent. It is also true that this system was less aristocratic than the recommendation on the basis of family standing which was used during the Period of Division." [1]

[1]: (Rodzinski 1979, 119)


Full Time Bureaucrat:
present

"The examination system was initiated in a partial form during the Han but had been in abeyance during practically all of the Period of Division. Under the Sui and T’ang it was taken up again and developed still further, reaching its full scope by the 8th century and becoming an important, although not the major, form for the recruiting of officials to the government bureaucracy. It should be noted, however, that the descendants of high officials had the right of entry into the register of officials without taking examinations." [1]

It should be noted, however, that the descendants of high officials had the right of entry into the register of officials without taking examinations." [1]
The examination system became more widespread during the Tang dynasty [2] Although, it was still somewhat limited in its use due to the aristocratic society of this period. [3]

"The first mention of what we would call gunpowder appeared in 808... These mixtures grew out of a very long tradition of alchemical experimentation usually tied to certain schools of Daoism that sought elixirs of immortality or the means to transmute one material into another. While all of our early evidence for alchemical mixtures is tied to Daoists, this may be a historiographical artifact produced by the better preservation of texts tied to that school of though (in all its varieties). There were also medical specialists, among others, interested in the effects of various substances and compounds on materials and bodies." [1]

History:

"...establishment of the History Office which was first set up for the purpose of writing the history of the five preceding dynasties and for the preparation and collection of materials for the elaboration of T’ang history as well." [1] "Another form of historical writing which developed in the T’ang period was that of institutional political history. This was represented by the works of Tu Yu (735-812), especially his famous T’ung-tien ("Comprehensive Statutes"), an encyclopaedic compendium of 200 chapters. In this work Tu Yu broke away from the chronological pattern of Standard Histories and, desirous of studying a number of problems in their historical development, he arranged his data according to subject-matter. Thus he deals with: (1) political economy, (2) examinations, (3) officials, (4) rites, (5) music, (6) army, (7) law, (8) geography of the empire and (9) geography of frontier regions. Tu Yu’s work became a model for many future encyclopaedias of a smiliar nature." [2]

[2] Liu Tsung-yuan (773-819) who wrote "the famous parable The Snake Catchers, an ironical depiction of the ravaging of the peasants by the tax collectors." [3] "The T’ang period also saw the appearance of a new form of literary creation - the short story. This originated already in the 6th century but the best examples date from the the middle of the 8th century and provide a vivid picture of T’ang society." [3]

Wootz steel was "being exported from India to China at least as early as the +5th century. … good steel was manufactured in China by remarkably modern methods at least from that time onwards also." [1] First high-quality steel 450 CE. Japan exported steel swords to China (time not stated, possibly once the Japanese had refined their methods, before the Song Dynasty). [2] "according to Wagner there is no direct evidence that cast steel was made in China. ... Exports of bin iron from Persia and Jaguda (Ghazni) to China in 6th-7th centuries are recorded. This was an imported steel of high quality. Curiously, bin iron disappears from Chinese sources after the 7th century, then reappears from 10th-17th centuries. This might have been a consequence of the Islamic conquest of Persia, followed by the rise of trade routes to China used by Arabs. An account of an embassy sent by the Yuan to Hulagu Khan in 1259 mention that bin iron was made in India." [3]

The frame of the whirlwind trebuchet was a single vertical pole that could be rotated horizontally through 360 degrees, thus allowing a wide arc of fire for comparatively lightweight missiles. Another picture in the same source shows a whirlwind trebuchet mounted on a four-wheeled carriage, which would make it even more flexible." [2]
