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).
Under Early Tang leadership, China’s territory expanded considerably. Conquered territories included large areas of Central Asia and northern Korea (Koguryō).
[3]
In later years, however, China pursued a defensive, non-expansionist policy towards groups on the steppe and frontier.
[4]
The dynasty, also known as the Tang (T’ang) Empire or Li Dynasty, is famous for its poetry, literature, increased trade and general cosmopolitanism.
[5]
In 660 CE, Empress Wu became the first woman to rule China, first governing as a regent to her young son and later ruling as empress dowager and regent until her death in 705 CE.
[6]
Emperor Xuanzong’s 44-year reign (712‒756 CE) ushered in a cultural and economic golden age, which declined as he aged and ended in rebellion and an overthrow of the dynasty.
[7]
Population and political organization
Emperor Gaozu worked to restore control of the imperial government that had been established by the Sui Dynasty, and founded frontier garrisons controlled directly by the capital.
[8]
The Tang instituted the much discussed ’equal fields’ system, in which land owned by the state was parcelled out in equal allotments to citizens in return for taxation. The Tang also minted many new coins in an attempt to stabilize the economy.
[8]
The Early Tang imperial government was characterized by an emperor who theoretically had absolute power, but was often in practice overruled by ministers or regents.
[9]
The central government was headed by three chief ministers who ran the Imperial Chancellery, Imperial Secretariat, and the Department for State Affairs.
[9]
The government also included a large central and state bureaucracy, marked by the expanding use of merit examinations.
[10]
The population of the Early Tang Dynasty is estimated at 37 million in 700 CE and increased to almost 53 million by 754 CE.
[11]
In the 8th century, there were an estimated 1 million people living in Chang’an.

Xuanzong (712-756 CE): "longest reigning of all the T’ang monarchs ... restored his dynasty to a new peak of power after decades of usurpation, weakened authority and corruption. Through the Chinese living through the troubled and disturbed decades which followed his abdication, his reign represented a golden age of departed glories, an era of good government, peace and prosperity, equally successful at home and abroad."
[1]
Reign of Li Shimin (Taizong) 627-649 CE was "the zenith of the T’ang dynasty... More than a century of internal peace followed Tai-tsung’s reign..."
[2]
However the zenith of the T’ang dynasty might not mean the same thing as the zenith of the T’ang dynasty’s polity.
During reign of Xuanzong (712-756 CE) "the Empire seemed - at least outwardly - to be more prosperous and stable than ever before. The increase in population was steady ... The wealth of the country was obvious ... and ’one could undertake a voyage within the empire for a distance of 10,000 li without being armed’. Thus, it seemed that the T’ang had reached a new pinnacle of glory. This is especially true if the period were to be regarded from the point of view of the arts, for it was precisely in this era that the greatest flourishing of T’ang culture took place."
[3]
Xuanzong (712-756 CE): "it was not he who ruled during the latter period from about 740 but his Chancellor Li Lin fu (in office 736-752), who established himself an unchallenged master of the Empire."

"In 617, when it was obvious that the Sui were finished, Li Yuan marched on Ch’ang-an with an army of 200,000 which included many Turkish auxiliaries. In the subsequent year Li Yuan proclaimed himself Emperor of the T’ang (Kao-tsu 618-626)."
[1]
"The policies established at the outset of the T’ang era were followed, in general, during the long reign of T’ai-tsung’s successor, Kao-tsung (650-683)."
[2]
"In 712 Jui-tsung resigned in favour of his son who was to become the famous Emperor Hsuan-tsung (712-756). His long and eventful reign marks, in fact, a turning-point in the development of China and in the fate of the T’ang dynasty..."
[3]
"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."

"In evolving the forms of a new centralized government the T’ang based themselves on their predecessors, partially on the Sui but, in reality they reached back to the Han period. Their policy, however, differed in one very important respect from that of the Han: the establishment of semi-independent princedoms was not permitted and the entire country was ruled as one state and empire."

Emperor Taizong: "637 ... he ordered that henceforth at all ceremonies Daoist monks and nuns would take precedence over their Buddhist counterparts."
[1]
"At about the same time he approved the Daoseng ge, the Regulations Regarding the Daoist and Buddhist Clergies, which provided harsh punishments for clergy committing various offences. His objective was to reduce the participation of Buddist clergy in secular life and to confine monks and nuns to their monasteries where they would be occupied with religious observances. By so doing he sought to establish control over the Buddhist church."
[1]
Empress Wu: "... Buddhism reached the apogee of its economic and political might during her reign. The Buddhist monasteries were the repositories for much capital, the owners of vast quantities of metal (primarily copper, mostly in the form of statues) and were thus able to control the money market. They were probably also the greatest single group of landowners in the entire country. On the whole, the Buddhists were able to maintain this dominant position for the next century and a half."

Units contained both cavalry and infantry, and were subdivided into t’uan of 200 men, tui of 50, and huo of 10."
[3]
"Many of the peasants in areas of strategic importance were also obliged to serve in militia units for a specified period of time - usually one month in five. There were approximately 630 militia units, each of them theoretically composed of 1000 men. This system prevailed until almost the middle of the 8th century when it disintegrated, for a number of reasons, and was replaced by a standing army."

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."

"a permanent level of authority intermediate between central government and individual prefectures." However, they were purely advisory and inspection and had no executive powers or civil jurisdiction.

"In addition to his military responsibilities the new military governor also held broad civil power over local administration, finance and supply."
[13]
"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..."

"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)
"The T’ang bureaucracy was not only enlarged but it also ceased ultimately to be the monopoly of the great families. Due to the steady development of the examination system and the expansion of education which was connected with this, the entry into officialdom was widened so as to include the majority of the landowning class." [1]
[1]: (Rodzinski 1979, 118)
"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]
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.

"Whilst based on those of the preceding dynasties, the T’ang legal code was simplified in comparison with these and was supposedly less serve in its penal provisions, particularly when contrasted with some of the draconian measures which had been introduced by the Sui."
[1]
Emperor Gaozu "set up a legal commission which, building on the Sui achievement, codified the law and administrative statutes in the form which was not only to remain in force until the fourteenth century, but which became the basis of the first legal codes in Vietnam, Korea and Japan."

Legal code compiled first in 624 CE.

"Starting with the Northern Qi dynasty (550-77) the most serious unpardonable "Ten Evil Crimes" (shi eh) were formally entered in the law Beiqi Lu (Sui shu: ch. 25). These were also codified in the laws of the Sui and Tang dynasties, followed by all succeeding dynasties, and continued to be in effect until the twentieth century."

"As in earlier periods, sophisticated siege equipment was available, including artillery, towers and rams." [1] Traction trebuchets. "A Tang dynasty description from 759 is very similar to that from Mo Zi, but includes references to ‘whirlwind trebuchets’ and ‘four-footed trebuchets’, two variations that are illustrated in the Wu Jing Zong Yao of 1044. 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]

"Infantry in the 6th and 7th centuries was divided into pu-pin, or marching infantry, armed with spears, and pu-she, or archers. The crossbow, the principal weapon of Han infantry, appears to have been less common in this period than the composite bow, although there are hints that it may have retained its importance in the south."
