flogging, castration, and death. In the most heinous cases the death sentence was carried out publicly, but senior officials and members of the imperial family were usually allowed to avoid such a scene by committing suicide. When the death penalty was invoked, a criminal’s goods, including members of his family, were confiscated by the state. Such persons then became slaves of the state and were employed on menial or domestic tasks in government offices. Government slaves were sometimes given as rewards to meritorious officials.

Relations with oTher peOPLES

Simultaneously with the rise of the Qin and Han empires, some of the nomadic peoples of Central Asia, known as the Xiongnu, succeeded in achieving a measure of unity under a single leader. As a result, while the Chinese were consolidating their government, the lands lying to the north of the empire—and the northern provinces themselves—became subject to incursion by Xiongnu horsemen. One of the achievements of the Qin dynasty had been the unification of the several lines of defense into a single system of fortification, the Great Wall. By keeping that wall, or line of earthworks, manned, the Qin dynasty had been free of invasion. With the fall of Qin and China’s subsequent weakness, the wall fell into a state of disrepair and lacked a garrison. Until about 135 BC, Han governments were obliged to seek peaceful

relations with the Xiongnu at the price of gold, silk, and even the hand of a Chinese princess. However, as Wudi’s governments began establishing strong policies, China took the offensive in an attempt to throw back the Xiongnu to Central Asia and to free the northern provinces from the threat of invasion and violence. By 119 BC, campaigns fought to the north of Chinese territory had attained this objective, and after a short interval it was possible to send Han armies to advance in the northeast (present-day North Korea), the south (present-day Vietnam), and the southwest. As a result of the campaigns fought from 135 BC onward, 18 additional commanderies were founded, and organs of Han provincial government were installed as outposts among peoples who were unassimilated to a Chinese way of life.

Chinese government was by no means universally accepted in those outlying regions. But despite large losses and expenditures incurred in fighting the Xiongnu, the Chinese were able to mount expeditions into Central Asia from about 112 BC. The defensive walls were repaired and remanned, and by about 100 they were extended to the northwest as far as Dunhuang. Chinese travelers, whether diplomats or merchants, were thus protected as far as the Takla Makan Desert. It was at about that time that trade routes skirting the desert were established and came to be known collectively as the Silk Road.

The success of Chinese arms in those remote areas was short-lived. Long lines

of communication made it impossible to set up garrisons or colonies in the forbidding country to the west of Dunhuang. Diplomatic moves were made to implant Chinese prestige more firmly among the communities that were situated around the Takla Makan Desert and that controlled the oases; it was necessary for the Chinese to win those peoples’ support, thus denying it to the Xiongnu. In a few cases the Chinese resorted to violence or plots to remove a leader and to replace him with a candidate known to favour the Han cause. More commonly, one of the alien leaders was married to a Chinese princess, with the intention that he should in time be succeeded by an heir who was half-Chinese. These endeavours and the military ventures met with partial success. While the Chinese position in Central Asia was subject to question, relations with the Xiongnu leaders varied. The visit of a Xiongnu leader to Chang’an in 51 BC was hailed as a mark of Chinese success, but the ensuing decades were not free from fighting. Chinese prestige declined toward the end of the Xi Han and recovered only during the reigns of Mingdi and Zhangdi, when the Han government was once more strong enough to take the field. Ban Chao’s campaigns in Central Asia (from AD 94) reestablished the Chinese position, but again the full strength of Chinese prestige lasted for only a few decades. During the Dong Han, China suffered invasion from the northeast as well as from the north. The settlement of Xiongnu peoples south of the wall was a

disruptive factor in the 2nd and 3rd centuries, to the detriment of imperial unity.

The Han expansion into Central Asia has been represented by the Chinese as a defensive measure designed to weaken the Xiongnu and to free China from invasion. Allowance must also be made for commercial motives. Some of Wudi’s statesmen were well aware of the advantages of exporting China’s surplus products in return for animals and animal products from Central Asia, and there is evidence that Chinese silk was exported at this time. No attempt can be made to estimate the volume of trade, and, as the transactions were conducted through Parthian middlemen, no direct contact was made by this means between Han China and the world of Rome and the Mediterranean. China’s export trade was sponsored by the government and not entrusted to private merchants.

The Great Wall formed a boundary separating the Chinese provinces from the outside world. Traffic was controlled at points of access, not only to check incoming travelers to China but also to prevent the escape of criminals or deserters. At the same time, a ban was imposed on the export of certain goods such as iron manufactures and weapons of war. The wall also formed a protected causeway for travelers to the west. Watch stations were erected in sight of each other to signal the approach of the enemy, and the garrison troops were highly trained and disciplined. Meticulous records were kept to show how government stores were expended and rations

issued; routine signals were relayed along the line and daily patrols were sent out to reconnoitre.

As a result of the campaigns and diplomatic activity, China’s immediate contacts with other peoples grew more brisk. Many of the Xiongnu and other neighbouring leaders who had surrendered to Han arms were given nobilities and settled in the interior of the empire. Zhang Qian was a pioneer who had set out about 130 BC to explore the routes into Central Asia and northern China, and, as a result of his report and

observations, Han advances were concentrated in the northwest. In AD 97 Chinese envoys were frustrated in an attempt to visit the western part of the world, but a mission from Rome reached China by ship in 166. The first record of official visitors arriving at the Han court from Japan is for the year AD 57.

CuLTuRaL DEvELOPMENTS

The Han emperors and governments posed as having a temporal dispensation that had received the blessing of heaven

together with its instructions to spread the benefits of a cultured life as widely as possible. By a cultured life the Chinese had in mind a clear distinction between their own settled agriculture and the delights of the cities, as opposed to the rough and hardy life spent in the saddle by the nomads of Central Asia. The growth of Han government both depended on and encouraged the development of literary accomplishment, scholastic competence, religious activity, scientific discovery, and technological achievement.

Han administration required detailed record keeping, which generated a proliferation of documents. Official returns were sometimes kept in duplicate, and each agency kept running files to record its business. Following a reform of the script that had evolved before the Han period, a new style of writing was developed that was suited to compiling official documents. These were written mostly on bulky and fragile wooden strips; silk was also used as a writing medium. A major development in world history occurred in China in AD 105 when officials reported to the throne the manufacture of a new substance. Although archaeological evidence indicates the existence of paper for more than a century before this incident, the earlier materials were not completely superseded until some three or four centuries later. In the meantime, the written vocabulary of the Chinese had increased in response to the demands of a growing civilization. The first Chinese dictionary,

completed in AD 121, included more than 9,000 separate ideograms (characters), with explanations of their meanings and the variant forms used in writing.

In an attempt to break with earlier tradition, the Qin government had taken certain steps to proscribe literature and learning. Han governments stressed their desire to promote these causes as part of their mission. In particular, they displayed a veneration for works with which Confucius had been associated, either as a collector of texts or as an editor, and these works became known as the Wujing, or the Confucian Classics. Beginning during the reign of Wendi, orders were given to search for books lost during the previous dynasty. Knowledge of texts such as the Shijing (“Classic of Poetry”), the Shujing (“Classic of History”), the Yijing (“Classic of Changes”), and the Chunqiu (“Spring and Autumn”) annals became a necessary accomplishment for officials and candidates for the civil service. To support an argument laid before the throne, statesmen would find a relevant quotation from these works; already in the 1st century BC the tradition was being formed whereby the civil service of imperial China was nurtured on a Classical education. On two occasions (51 BC and AD 79) the government ordered official discussions about interpreting texts and the validity of differing versions; in AD 175 work was completed on a project that inscribed an approved version on stone tablets, so as to allay scholastic doubts in the future. In the meantime—and still before the invention

of paper—a collection of literary texts had been made for the imperial library. The catalog of this collection, which dates from the early 1st century AD, was prepared after comparing different copies and eliminating duplicates. The list of titles has been preserved and constitutes China’s first bibliographical list. The works are classified according to subject, but many have been lost. The importance of these measures lies both in their intrinsic achievement and in the example they set for subsequent dynasties.

The prose style of Han writers was later taken as a model of simplicity, and, as a reaction to the literary embellishments and artificialities introduced in the 5th and 6th centuries, deliberate attempts were made to revert to its natural elegance. Examples of this direct prose may be seen in the imperial edicts, the memorials ascribed to statesmen, and, above all, the text of the standard histories themselves, in which such documents of state were incorporated. Compiling the standard histories was a private undertaking in Han times, but it already received imperial patronage and assistance. History was written partly to justify the authority and conduct of the contemporary regime and partly as a matter of pride in Chinese achievement. Further examples of prose writing are the descriptions of protocol for the court. One of the

earliest acts of the Han government (c. 200 BC) had been to order the formulation of such modes of behaviour as a means of enhancing the dignity of the throne, and one of the latest compilations (c. AD 175) that still survives is a list of such prescriptions, drawn up at a time when the dynasty was manifestly losing its majesty and natural authority. Some of the emperors were themselves composers of versified prose; their efforts have also been preserved in the standard histories.

The emperor was charged with the solemn duty of securing the blessings of spiritual powers for mankind. One of the nine ministries of state existed to assist in this work of mediation, but from the time of Wudi onward the emperor himself began to play a more active part in worship and sacrifice. The cults were initially addressed to the Five Elements (fire, water, earth, wood, and metal), to the Supreme Unity, and to the Lord of the Soil. In 31 BC these cults were replaced by sacrifices dedicated to heaven and earth. The sites of worship were transferred to the southern and northern outskirts of Chang’an, and a new series of altars and shrines was inaugurated. The Han emperor occasionally paid his respects to supreme powers and reported on the state of the dynasty at the summit of Mount Tai. Wudi’s desire for immortality

and for quickening his deceased favourites led him to patronize a number of intermediaries who claimed to possess the secret of making contact with the world of the immortals. From such beliefs and from a fear of the malevolent influences that the unappeased souls of the dead could wreak on humanity, a few philosophers such as Wang Chong (AD 27–c. 100) reacted by propounding an ordered and rational explanation of the universe. But their skepticism received little support. Sometime during the 1st century AD, Buddhism reached China, propagated in all probability by travelers who had taken the Silk Road from northern India. Shortly thereafter Buddhist foundations were established in China, as well as the first official patronage of the faith. From the 2nd century AD there arose a variety of beliefs, practices, and disciplines from which alchemy and scientific experiment were to spring and which were to give rise to Daoism.

Most of the cultural attainments of the Han period derived from imperial encouragement and the needs of officials. A textbook of mathematical problems was probably compiled to assist officials in work such as land assessment; fragments of a medical casebook were concerned with the care of

troops and horses serving on the northwestern frontier. Water clocks and sundials were used to enable officials to complete their work on schedule. The palace demanded the services of artists and craftsmen to decorate imperial buildings with paintings and sculptures and to design and execute jades, gold and silver wares, and lacquer bowls for use at the imperial table. Intricate patterns in multicoloured silks were woven on looms in the imperial workshops. On a more mundane level, technology served the cause of practical government. The state’s ironwork factories produced precision-made instruments and weapons of war, and the state’s agencies for the salt industry supervised the recovery of brine from deep shafts cut in the rocks of western China. Water engineers planned the construction of dikes to divert the flow of excess waters and the excavation of canals to serve the needs of transport or irrigation, and in many parts of the countryside there could be seen a sight that remained typical of the Chinese landscape up to the 20th century—a team of two or three peasants sitting astride a beam and pedaling the lugs of the “dragon’s backbone” that raised water from the sluggish channels below to the upper levels of the cultivated land.
