TheHan dynastywas animperial dynasty of China(202 BC – 9 AD, 25–220 AD) established byLiu Bangand ruled by the House of Liu. The dynasty was preceded by the short-livedQin dynasty(221–206 BC) and a warringinterregnumknown as theChu–Han contention(206–202 BC), and it was succeeded by theThree Kingdomsperiod (220–280 AD). The dynasty was briefly interrupted by theXin dynasty(9–23 AD) established by the usurping regentWang Mang,and is thus separated into two periods—theWestern Han(202 BC – 9 AD) and theEastern Han(25–220 AD). Spanning over four centuries, the Han dynasty is considered agolden age in Chinese history,and had a permanent impact on Chinese identity in later periods.The majority ethnic group of modern China refer to themselves as the "Han people"or" Han Chinese ". The spokenSinitic languageandwritten Chineseare referred to respectively as the "Han language" and "Han characters".

The emperorwas at the pinnacle ofHan society and culture.He presided over theHan governmentbut shared power with boththe nobilityand the appointed ministers who came largely from the scholarlygentry class.The Han Empire was divided into areas directly controlled by the central government calledcommanderies,as well as a number ofsemi-autonomous kingdoms.These kingdoms gradually lost all vestiges of their independence, particularly following theRebellion of the Seven States.From the reign ofEmperor Wu(r. 141–87 BC) onward, the Chinese court officially sponsoredConfucianismin education and court politics, synthesized with thecosmologyof later scholars such asDong Zhongshu.This policy endured until the fall of theQing dynastyin 1912.

The Han dynasty oversawperiods of economic prosperityas well as significant growth in themoney economythat had first been established during theZhou dynasty(c. 1050– 256 BC).The coinageminted by the central government in 119 BC remained the standard in China until theTang dynasty(618–907 AD). The period saw a number of limited institutional innovations. To finance its military campaigns and the settlement of newly conquered frontier territories, the Han governmentnationalizedprivate salt and iron industries in 117 BC, creating government monopolies that were later repealed during the Eastern period. There were significant advances inscience and technologyduring the Han period, including the emergence ofpapermaking,ruddersfor steering ships,negative numbersinmathematics,raised-relief maps,hydraulic-poweredarmillary spheresforastronomy,andseismometersthat discerned the cardinal direction of distant earthquakes by use ofinverted pendulums.

The Han dynasty had many conflicts with theXiongnu,a nomadic confederation centred in the easternEurasian steppe.The Xiongnudefeated the Han in 200 BC,prompting the Han to appease the Xiongnu with a policy of marriage alliance and payments of tribute, though the Xiongnu continued to raid the Han's northern borders. Han policy changed in 133 BC, underEmperor Wu,when Han forces began aseries of military campaignsto quell the Xiongnu. The Xiongnu were eventually defeated and forced to accept a status asHan vassals,and the Xiongnu confederation fragmented. The Han conquered theHexi CorridorandInner Asian territoryof theTarim Basinfrom the Xiongnu, helping to establish theSilk Road.The lands north of the Han's borders were later overrun by the nomadicXianbeiconfederation. Emperor Wu also launched successfulconquests in the south,anne xingNanyue in 111 BCandDian in 109 BC.He further expanded Han territory into the northernKorean Peninsula,where Han forcesconquered Gojoseonand established theXuantuandLelangcommanderies in 108 BC. After 92 AD, palaceeunuchsincreasingly involved themselves in the dynasty's court politics, engaging in violent power struggles between variousconsort clansof the empresses andempresses dowager.Imperial authority was also seriously challenged by largeDaoistreligious societies which instigated theYellow Turban Rebellionand theFive Pecks of Rice Rebellion.Following the death ofEmperor Ling(r. 168–189 AD), the palace eunuchswere massacredby military officers, allowing members of the aristocracy and military governors to become warlords anddivide the empire.The Han dynasty came to an end in 220 AD whenCao Pi,king ofWei,usurped the throne fromEmperor Xian.

Etymology

According to theRecords of the Grand Historian,after the collapse of theQin dynastythe hegemonXiang YuappointedLiu Bangas prince of the small fief ofHanzhong,named after its location on theHan River(in modern southwestShaanxi). Following Liu Bang's victory in theChu–Han Contention,the resulting Han dynasty was named after the Hanzhong fief.

China's firstimperial dynastywas theQin dynasty(221–207 BC). The Qin united the ChineseWarring Statesby conquest, but their regime became unstable after the death of the first emperorQin Shi Huang.Within four years, the dynasty's authority had collapsed in a rebellion.Two former rebel leaders,Xiang Yu(d. 202 BC) ofChuandLiu Bang(d. 195 BC) ofHan,engagedin a warto determine who would have hegemony over China, which had fissured intoEighteen Kingdoms,each claiming allegiance to either Xiang Yu or Liu Bang.Although Xiang Yu proved to be an effective commander, Liu Bang defeated him at theBattle of Gaixia(202 BC) in modern-dayAnhui.Liu Bang assumedthe title of Emperorat the urging of his followers and is known posthumously asEmperor Gaozu(r. 202–195 BC).Chang'an(modern Xi'an) was chosen as the new capital of the reunified empire under Han.

Thirteen direct-controlledcommanderiesincluding the capital region (yellow) and ten semi-autonomous kingdoms, 195 BC

At the beginning of theWestern Han(traditional Chinese:Tây Hán;simplified Chinese:Tây Hán;pinyin:Xīhàn), also known as theFormer Han(Tây Hán;Tây Hán;Qiánhàn), thirteen centrally-controlledcommanderies—including the capital region—existed in the western third of the empire, while the eastern two-thirds were divided into tensemi-autonomous kingdoms.To placate his prominent commanders from the war with Chu, Emperor Gaozuenfeoffedsome of them as kings.

By 196, the Han court had replaced all of these kings with royalLiufamily members, with the lone exception ofChangsha.The loyalty of non-relatives to the emperor was questioned,and after several insurrections by Han kings—with the largest being theRebellion of the Seven Statesin 154—the imperial court began enacting a series of reforms that limited the power of these kingdoms in 145, dividing their former territories into new commanderies under central control.Kings were no longer able to appoint their own staff; this duty was assumed by the imperial court.Kings became nominal heads of theirfiefsand collected a portion of tax revenues as their personal incomes.The kingdoms were never entirely abolished and existed throughout the remainder of Western and Eastern Han.

To the north ofChina proper,the nomadicXiongnuchieftainModu Chanyu(r. 209–174 BC) conquered various tribes inhabiting the eastern portion of theEurasian Steppe.By the end of his reign, he controlled theInner Asianregions ofManchuria,Mongolia,and theTarim Basin,subjugating over twenty states east ofSamarkand.Emperor Gaozu was troubled about the abundant Han-manufactured iron weapons traded to the Xiongnu along the northern borders, and he established a tradeembargoagainst the group.

In retaliation, the Xiongnu invaded what is nowShanxi,where theydefeated the Han forces at Baidengin 200 BC.After negotiations, theheqinagreement in 198 BC nominally held the leaders of the Xiongnu and the Han as equal partners in a royal marriage alliance, but the Han were forced to send large amounts of tribute items such as silk clothes, food, and wine to the Xiongnu.

Despite the tribute and negotiation betweenLaoshang Chanyu(r. 174–160 BC) andEmperor Wen(r. 180–157 BC) to reopen border markets, many of theChanyu's subordinates chose not to obey the treaty and periodically raided Han territories south of theGreat Wallfor additional goods.In a court conference assembled byEmperor Wu(r. 141–87 BC) in 135 BC, themajority consensusof the ministers was to retain theheqinagreement. Emperor Wu accepted this, despite continuing Xiongnu raids.

However, a court conference the following year convinced the majority that alimited engagement at Mayiinvolving the assassination of the Chanyu would throw the Xiongnu realm into chaos and benefit the Han.When this plot failed in 133 BC,Emperor Wu launched a series ofmassive military invasionsinto Xiongnu territory. The assault culminated in 119 BC at theBattle of Mobei,when Han commandersHuo Qubing(d. 117 BC) andWei Qing(d. 106 BC) forced the Xiongnu court to flee north of theGobi Desert,and Han forces reached as far north asLake Baikal.

After Wu's reign, Han forces continued to fight the Xiongnu. The Xiongnu leaderHuhanye(r. 58–31 BC) finally submitted to the Han as a tributary vassal in 51 BC. Huhanye's rival claimant to the throne,Zhizhi Chanyu(r. 56–36 BC), was killed by Han forces underChen Tangand Gan Yanshou (Cam duyên thọ) at theBattle of Zhizhi,in modernTaraz,Kazakhstan.

In 121 BC, Han forces expelled the Xiongnu from a vast territory spanning theHexi CorridortoLop Nur.They repelled a joint Xiongnu-Qianginvasion of this northwestern territory in 111 BC. In that same year, the Han court established four new frontier commanderies in this region to consolidate their control:Jiuquan,Zhangyi,Dunhuang,andWuwei.The majority of people on the frontier were soldiers.On occasion, the court forcibly moved peasant farmers to new frontier settlements, along with government-owned slaves and convicts who performed hard labour.The court also encouraged commoners, such as farmers, merchants, landowners, and hired labourers, to voluntarily migrate to the frontier.

Even before the Han's expansion into Central Asia, diplomatZhang Qian's travels from 139 to 125 BC had established Chinese contacts with many surrounding civilizations. Zhang encounteredDayuan(Fergana),Kangju(Sogdiana), andDaxia(Bactria,formerly theGreco-Bactrian Kingdom); he also gathered information on Shendu (theIndus Rivervalley) and Anxi (theParthian Empire). All of these countries eventually received Han embassies.These connections marked the beginning of theSilk Roadtrade network that extended to theRoman Empire,bringing goods like Chinese silk and Roman glasswares between the two.

Fromc. 115 BCuntilc. 60 BC,Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. The Han was eventually victorious and established theProtectorate of the Western Regionsin 60 BC, which dealt with the region's defence and foreign affairs.The Han alsoexpanded southward.Thenaval conquest of Nanyuein 111 BC expanded the Han realm into what are now modernGuangdong,Guangxi,and northern Vietnam.Yunnanwas brought into the Han realm with theconquestof theDian Kingdomin 109 BC, followed by parts of theKorean Peninsulawith theHan conquest of Gojoseonand establishment of theXuantuandLelang commanderiesin 108 BC.The first nationwide census in Chinese history was taken in 2 AD; the Han's total population was registered as comprising 57,671,400 individuals across 12,366,470 households.

To pay for his military campaigns and colonial expansion, Emperor Wunationalisedseveral private industries. He created central governmentmonopoliesadministered largely byformer merchants.These monopolies included salt, iron, and liquor production, as well asbronze coinage.The liquor monopoly lasted only from 98 to 81 BC, and the salt and iron monopolies were eventually abolished in the early Eastern Han. The issuing of coinage remained a central government monopoly throughout the rest of the Han dynasty.

The government monopolies were eventually repealed when a political faction known as the Reformists gained greater influence in the court. The Reformists opposed the Modernist faction that had dominated court politics in Emperor Wu's reign and during the subsequentregencyofHuo Guang(d. 68 BC). The Modernists argued for an aggressive and expansionary foreign policy supported by revenues from heavy government intervention in the private economy. The Reformists, however, overturned these policies, favouring a cautious, non-expansionary approach to foreign policy, frugalbudgetreform, and lower tax-rates imposed on private entrepreneurs.

Wang Zhengjun(71 BC – 13 AD) was first empress, thenempress dowager,and finallygrand empress dowagerduring the reigns of the EmperorsYuan(r. 49–33 BC),Cheng(r. 33–7 BC), andAi(r. 7–1 BC), respectively. During this time, a succession of her male relatives held the title of regent.Following the death of Ai, Wang Zhengjun's nephewWang Mang(45 BC – 23 AD) was appointed regent as Marshall of State on 16 August underEmperor Ping(r. 1 BC – 6 AD).

When Ping died on 3 February 6 AD,Ruzi Ying(d. 25 AD) was chosen as the heir and Wang Mang was appointed to serve as acting emperor for the child.Wang promised to relinquish his control to Liu Ying once he came of age.Despite this promise, and against protest and revolts from the nobility, Wang Mang claimed on 10 January that the divineMandate of Heavencalled for the end of the Han dynasty and the beginning of his own: theXin dynasty(9–23 AD).

Wang Mang initiated a series of major reforms that were ultimately unsuccessful. These reforms included outlawing slavery,nationalizingandequally distributingland between households, and introducing new currencies, a change which debased the value of coinage.Although these reforms provoked considerable opposition, Wang's regime met its ultimate downfall with the massive floods ofc. 3AD and 11 AD. Gradual silt build-up in theYellow Riverhad raised its water level and overwhelmed theflood control works.The Yellow River split into two new branches: one emptying to the north and the other to the south of theShandong Peninsula,though Han engineers managed to dam the southern branch by 70 AD.

The flood dislodged thousands of peasant farmers, many of whom joined roving bandit and rebel groups such as theRed Eyebrowsto survive.Wang Mang's armies were incapable of quelling these enlarged rebel groups. Eventually, an insurgent mob forced their way into theWeiyang Palaceand killed Wang Mang.

TheGengshi Emperor(r. 23–25 AD), a descendant ofEmperor Jing(r. 157–141 BC), attempted to restore the Han dynasty and occupied Chang'an as his capital. However, he was overwhelmed by the Red Eyebrow rebels who deposed, assassinated, and replaced him with the puppet monarchLiu Penzi.Gengshi's distant cousin Liu Xiu, known posthumously asEmperor Guangwu(r. 25–57 AD), after distinguishing himself at theBattle of Kunyangin 23 AD, was urged to succeed Gengshi as emperor.

Under Guangwu's rule, the Han Empire was restored. Guangwu madeLuoyanghis capital in 25 AD, and by 27 his officersDeng YuandFeng Yihad forced the Red Eyebrows to surrender and executed their leaders fortreason.From 26 until 36 AD, Emperor Guangwu had to wage war against other regional warlords who claimed the title of emperor; when these warlords were defeated, China reunified under the Han.

The period between the foundation of the Han dynasty and Wang Mang's reign is known as the Western Han (Tây Hán;Tây Hán;Xīhàn) or Former Han (Tây Hán;Tây Hán;Qiánhàn) (206 BC – 9 AD). During this period the capital was atChang'an(modernXi'an). From the reign of Guangwu the capital was moved eastward to Luoyang. The era from his reign untilthe fall of Hanis known as the Eastern Han or Later Han (25–220 AD).

Eastern Han

TheEastern Han(traditional Chinese:Đông Hán;simplified Chinese:Đông Hán;pinyin:Dōnghàn), also known as theLater Han(Đông Hán;Đông Hán;Hòuhàn), formally began on 5 August AD 25, when Liu Xiu becameEmperor Guangwu of Han.During the widespread rebellion againstWang Mang,the state ofGoguryeowas free to raid Han'sKorean commanderies;Han did not reaffirm its control over the region until AD 30.

TheTrưng SistersofVietnamrebelled against Han in AD 40. Their rebellion was crushed by Han generalMa Yuan(d. AD 49) in a campaign from AD 42 to 43.Wang Mang renewed hostilities against theXiongnu,who were estranged from Han until their leader Bi (So), a rival claimant to the throne against his cousin Punu (Bồ nô), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han.

During the turbulent reign of Wang Mang, China lost control over the Tarim Basin, which was conquered by the Northern Xiongnu in AD 63 and used as a base to invade the Hexi Corridor inGansu.Dou Gu(d. 88 AD) defeated the Northern Xiongnu at theBattle of Yiwuluin AD 73, evicting them fromTurpanand chasing them as far asLake Barkolbefore establishing a garrison at Hami.After the new Protector General of the Western RegionsChen Mu(d. AD 75) was killed by allies of the Xiongnu inKarasahrandKucha,the garrison at Hami was withdrawn.

At theBattle of Ikh Bayanin AD 89,Dou Xian(d. AD 92) defeated theNorthern Xiongnuchanyuwho then retreated into theAltai Mountains.After the Northern Xiongnu fled into theIli Rivervalley in AD 91, the nomadicXianbeioccupied the area from the borders of theBuyeo Kingdomin Manchuria to the Ili River of theWusunpeople.The Xianbei reached their apogee underTanshihuai(d. AD 181), who consistently defeated Chinese armies. However, Tanshihuai's confederation disintegrated after his death.

Ban Chao(d. AD 102) enlisted the aid of theKushan Empire,which controlled territory across South and Central Asia, to subdueKashgarand its ally Sogdiana.When a request by Kushan rulerVima Kadphises(r. c. 90– c. 100 AD–) for a marriage alliance with the Han was rejected in AD 90, he sent his forces toWakhan(modern-day Afghanistan) to attack Ban Chao. The conflict ended with the Kushans withdrawing because of lack of supplies.In AD 91, the office of Protector General of the Western Regions was reinstated when it was bestowed on Ban Chao.

Foreign travellers to the Eastern Han empire includedBuddhist monkswhotranslated works into Chinese,such asAn Shigaofrom Parthia, andLokaksemafrom Kushan-eraGandhara.In addition to tributary relations with the Kushans, the Han empire received gifts from sovereigns in theParthian Empire,as well as from kings in modernBurmaandJapan.He also initiated an unsuccessful mission toRomein AD 97 withGan Yingas emissary.

Emperor Zhang's (r. 75–88 AD) reign came to be viewed by later Eastern Han scholars as the high point of the dynastic house.Subsequent reigns were increasingly marked byeunuchintervention in court politics and their involvement in the violent power struggles of the imperialconsort clans.In 92 AD, with the aid of the eunuchZheng Zhong(d. 107 AD),Emperor He(r. 88–105 AD) hadEmpress Dowager Dou(d. 97 AD) put underhouse arrestand her clan stripped of power. This was in revenge for Dou's purging of the clan of his natural mother—Consort Liang—and then concealing her identity from him.After Emperor He's death, his wifeEmpress Deng Sui(d. 121 AD) managed state affairs as the regent empress dowager during a turbulent financial crisis and widespread Qiang rebellion that lasted from 107 to 118 AD.

When Empress Dowager Deng died,Emperor An(r. 106–125 AD) was convinced by the accusations of the eunuchs Li Run (Lý nhuận) and Jiang Jing (Giang kinh) that Deng and her family had planned to depose him. An dismissed Deng's clan members from office, exiled them, and forced many to commit suicide.After An's death, his wife,Empress Dowager Yan(d. 126 AD) placed the childMarquess of Beixiangon the throne in an attempt to retain power within her family. However, palace eunuchSun Cheng(d. 132 AD) masterminded a successful overthrow of her regime to enthroneEmperor Shun of Han(r. 125–144 AD). Yan was placed under house arrest, her relatives were either killed or exiled, and her eunuch allies were slaughtered.The regentLiang Ji(d. 159 AD), brother ofEmpress Liang Na(d. 150 AD), had the brother-in-law ofConsort Deng Mengnü(d. 165 AD) killed after Deng Mengnü resisted Liang Ji's attempts to control her. Afterward, Emperor Huan employed eunuchs to depose Liang Ji, who was then forced to commit suicide.

Students from theimperial universityorganized a widespreadstudent protestagainst the eunuchs of Emperor Huan's court.Huan further alienated the bureaucracy when he initiated grandiose construction projects and hosted thousands of concubines in his harem at a time of economic crisis.Palace eunuchs imprisoned the official Li Ying (Lý ưng) and his associates from the Imperial University on a dubious charge of treason. In 167 AD, the Grand CommandantDou Wu(d. 168 AD) convinced his son-in-law, Emperor Huan, to release them.However, the emperor permanently barred Li Ying and his associates from serving in office, marking the beginning of thePartisan Prohibitions.

Following Huan's death, Dou Wu and the Grand TutorChen Fan(d. 168 AD) attempted a coup against the eunuchsHou Lan(d. 172 AD),Cao Jie(d. 181 AD), and Wang Fu (Vương phủ). When the plot was uncovered, the eunuchs arrestedEmpress Dowager Dou(d. 172 AD) and Chen Fan. General Zhang Huan (Trương hoán) favoured the eunuchs. He and his troops confronted Dou Wu and his retainers at the palace gate where each side shouted accusations of treason against the other. When the retainers gradually deserted Dou Wu, he was forced to commit suicide.

UnderEmperor Ling(r. 168–189 AD) the eunuchs had the partisan prohibitions renewed and expanded, while also auctioning off top government offices.Many affairs of state were entrusted to the eunuchsZhao Zhong(d. 189 AD) andZhang Rang(d. 189 AD) while Emperor Ling spent much of his timeroleplayingwith concubines and participating in military parades.

The Partisan Prohibitions were repealed during theYellow Turban RebellionandFive Pecks of Rice Rebellionin 184 AD, largely because the court did not want to continue to alienate a significant portion of thegentry classwho might otherwise join the rebellions.The Yellow Turbans and Five-Pecks-of-Rice adherents belonged to two different hierarchicalTaoistreligious societies led by faith healersZhang Jue(d. 184 AD) andZhang Lu(d. 216 AD), respectively.

Zhang Lu's rebellion, in what is now northernSichuanand southernShaanxi,was not quelled until 215 AD.Zhang Jue's massive rebellion across eightprovinceswas annihilated by Han forces within a year; however, the following decades saw much smaller recurrent uprisings.Although the Yellow Turbans were defeated, many generals appointed during the crisis never disbanded their assembled militias and used these troops to amass power outside of the collapsing imperial authority.

General-in-chiefHe Jin(d. 189 AD), half-brother toEmpress He(d. 189 AD), plotted withYuan Shao(d. 202 AD) to overthrow the eunuchs by having several generals march to the outskirts of the capital. There, in a written petition to Empress He, they demanded the eunuchs' execution.After a period of hesitation, Empress He consented. When the eunuchs discovered this, however, they had her brother He Miao (Gì mầm) rescind the order.The eunuchs assassinated He Jin on 22 September 189.

Yuan Shao then besieged Luoyang's Northern Palace while his brotherYuan Shu(d. 199 AD) besieged the Southern Palace. On September 25 both palaces were breached and approximately two thousand eunuchs were killed.Zhang Rang had previously fled withEmperor Shao(r. 189 AD) and his brother Liu Xie—the futureEmperor Xian of Han(r. 189–220 AD). While being pursued by the Yuan brothers, Zhang committed suicide by jumping into the Yellow River.

GeneralDong Zhuo(d. 192 AD) found the young emperor and his brother wandering in the countryside. He escorted them safely back to the capital and was madeMinister of Works,taking control of Luoyang and forcing Yuan Shao to flee.After Dong Zhuo demoted Emperor Shao and promoted his brother Liu Xie as Emperor Xian, Yuan Shao led a coalition of former officials and officers against Dong, who burned Luoyang to the ground and resettled the court at Chang'an in May 191 AD. Dong Zhuo later poisoned Emperor Shao.

Dong was killed by his adopted sonLü Bu(d. 198 AD) in a plot hatched byWang Yun(d. 192 AD).Emperor Xian fled from Chang'an in 195 AD to the ruins of Luoyang. Xian was persuaded byCao Cao(155–220 AD), then Governor of Yan Province in modern westernShandongand easternHenan,to move the capital toXuchangin 196 AD.

Yuan Shao challenged Cao Cao for control over the emperor. Yuan's power was greatly diminished after Cao defeated him at theBattle of Guanduin 200 AD. After Yuan died, Cao killed Yuan Shao's sonYuan Tan(173–205 AD), who had fought with his brothers over the family inheritance.His brothersYuan ShangandYuan Xiwere killed in 207 AD byGongsun Kang(d. 221 AD), who sent their heads to Cao Cao.

After Cao's defeat at the navalBattle of Red Cliffsin 208 AD, China was divided into three spheres of influence, with Cao Cao dominating the north,Sun Quan(182–252 AD) dominating the south, andLiu Bei(161–223 AD) dominating the west.Cao Cao died in March 220 AD. By December his sonCao Pi(187–226 AD) had Emperor Xian relinquish the throne to him and is known posthumously asEmperor Wen of Wei.This formally ended the Han dynasty and initiated an age of conflict between theThree Kingdoms:Cao Wei,Eastern Wu,andShu Han.

Each successive rank gave its holder greater pensions and legal privileges. The highest rank, of fullmarquess,came with a state pension and a territorialfiefdom.Holders of the rank immediately below, that of ordinary marquess, received a pension, but had no territorial rule.Scholar-bureaucratswho served in government belonged to the wider commoner social class and were ranked just below nobles in social prestige. The highest government officials could be enfeoffed as marquesses.

By the Eastern Han, local elites of unattached scholars, teachers, students, and government officials began to identify themselves as members of a nationwidegentry classwith shared values and a commitment to mainstream scholarship.When the government became noticeably corrupt in mid-to-late Eastern Han, many gentry even considered the cultivation of morally-grounded personal relationships more important than serving in public office.

Farmers, namely small landowner–cultivators, were ranked just below scholars and officials in the social hierarchy. Other agricultural cultivators were of a lower status, such as tenants, wage labourers, and slaves.The Han dynasty made adjustments toslavery in Chinaand saw an increase in agricultural slaves. Artisans, technicians, tradespeople, and craftsmen had a legal and socioeconomic status between that of owner-cultivator farmers and common merchants.

State-registered merchants, who were forced by law to wear white-coloured clothes and pay high commercial taxes, were considered by the gentry as social parasites with a contemptible status.These were often petty shopkeepers of urban marketplaces; merchants such as industrialists and itinerant traders working between a network of cities could avoid registering as merchants and were often wealthier and more powerful than the vast majority of government officials.

Wealthy landowners, such as nobles and officials, often provided lodging for retainers who provided valuable work or duties, sometimes including fighting bandits or riding into battle. Unlike slaves, retainers could come and go from their master's home as they pleased.Physicians, pig breeders, and butchers had fairly high social status, while occultist diviners, runners, and messengers had low status.

The Han-era family waspatrilinealand typically had four to fivenuclear familymembers living in one household. Multiple generations ofextended familymembers did not occupy the same house, unlike families of later dynasties.According to Confucian family norms, various family members were treated with different levels of respect and intimacy. For example, there were different accepted time frames for mourning the death of a father versus a paternal uncle.

Marriages were highly ritualized, particularly for the wealthy, and included many important steps. The giving of betrothal gifts, known asbride priceanddowry,were especially important. A lack of either was considered dishonourable and the woman would have been seen not as a wife, but as a concubine.Arranged marriageswere typical, with the father's input on his offspring's spouse being considered more important than the mother's.

Monogamous marriages were also normal, although nobles and high officials were wealthy enough to afford and support concubines as additional lovers.Under certain conditions dictated by custom, not law, both men and women were able to divorce their spouses and remarry.However, a woman who had been widowed continued to belong to her husband's family after his death. In order to remarry, the widow would have to be returned to her family in exchange for a ransom fee. Her children would not be allowed to go with her.

Apart from the passing of noble titles or ranks,inheritancepractices did not involveprimogeniture;each son received an equal share of the family property.Unlike the practice in later dynasties, the father usually sent his adult married sons away with their portions of the family fortune.Daughters received a portion of the family fortune through their dowries, though this was usually much less than the shares of sons.A different distribution of the remainder could be specified in awill,but it is unclear how common this was.

Women were expected to obey the will of their father, then their husband, and then their adult son in old age. However, it is known from contemporary sources that there were many deviations to this rule, especially in regard to mothers over their sons, and empresses who ordered around and openly humiliated their fathers and brothers.Women were exempt from the annualcorvéelabour duties, but often engaged in a range of income-earning occupations aside from their domestic chores of cooking and cleaning.

The most common occupation for women was weaving clothes for the family, for sale at market, or for large textile enterprises that employed hundreds of women. Other women helped on their brothers' farms or became singers, dancers, sorceresses, respected medical physicians, and successful merchants who could afford their own silk clothes.Some women formed spinning collectives, aggregating the resources of several different families.

Education, literature, and philosophy

Model of the Han dynasty royal academy

The early Western Han court simultaneously accepted the philosophical teachings ofLegalism,Huang-LaoTaoism, andConfucianismin making state decisions and shaping government policy.However, the Han court underEmperor Wugave Confucianism exclusive patronage. In 136 BC, he abolished all academic chairs not concerned with theFive Classics,and encouraged nominees for office to receive a Confucian education at theimperial universityhe had established in 124.

Unlike the original ideology espoused byConfucius(551–479 BC), Han Confucianism in Emperor Wu's reign was the creation ofDong Zhongshu(179–104 BC). Dong was a scholar and minor official who aggregated the ethical Confucian ideas ofritual,filial piety,andharmonious relationshipswithfive phasesandyin-yangcosmologies.Dong's synthesis justified the imperial system of government within the natural order of the universe.

The Imperial University grew in importance as the student body grew to over 30,000 by the 2nd century AD.A Confucian-based education was also made available at commandery-level schools andprivate schoolsopened in small towns, where teachers earned respectable incomes from tuition payments.Schools were established in far southern regions where standard Chinese texts were used to assimilate the local populace.

A fragment of theXiping Stone Classics;these stone-carvedFive Classicsinstalled duringEmperor Ling's reign along the roadside of the imperial university right outside Luoyang, were made at the instigation ofCai Yong(132–192 AD), who feared the Classics housed in the imperial library were beinginterpolatedby University Academicians.

Some important texts were created and studied by scholars. Philosophy written byYang Xiong(53 BC – 18 AD),Huan Tan(43 BC – 28 AD),Wang Chong(27–100 AD), andWang Fu(78–163 AD) questioned whether human nature was innately good or evil and posed challenges to Dong's universal order.TheRecords of the Grand Historianstarted bySima Tan(d. 110 BC) and finished by his sonSima Qian(145–86 BC) established thestandard modelfor imperial China'stradition of official histories,being emulated initially by theBook of Hanauthored byBan Biao(3–54 AD) with his sonBan Gu(32–92 AD), and his daughterBan Zhao(45–116 AD).Biographieson important figures were written by members of the gentry.There were alsodictionariespublished during the Han period such as theShuowen JiezibyXu Shen(c. 58– c. 147 AD) and theFangyanbyYang Xiong.Han dynasty poetry was dominated by thefugenre,which achieved its greatest prominence during the reign of Emperor Wu.

Law and order

Han scholars such asJia Yi(201–169 BC) portrayed the Qin as a brutal regime. However, archaeological evidence fromZhangjiashanandShuihudireveal that many of the statutes in the Han law code compiled by ChancellorXiao He(d. 193 BC) were derived from Qin law.

Various cases for rape, physical abuse, and murder were prosecuted in court. Women, although usually having fewer rights by custom, were allowed to level civil and criminal charges against men.While suspects were jailed, convicted criminals were never imprisoned. Instead, punishments were commonly monetary fines, periods of forced hard labour for convicts, and the penalty of death by beheading.Early Han punishments of torturous mutilation were borrowed from Qin law. A series of reforms abolished mutilation punishments with progressively less-severe beatings by thebastinado.

Acting as a judge in lawsuits was one of the many duties of thecounty magistrateand Administrators of commanderies. Complex, high-profile, or unresolved cases were often deferred to the Minister of Justice in the capital or even the emperor.In each Han county was several districts, each overseen by a chief of police. Order in the cities was maintained by government officers in the marketplaces andconstablesin the neighbourhoods.

Food

Two Han dynasty red-and-blacklacquerwares,one a bowl, the other a tray; usually only wealthy officials, nobles, and merchants could afford domestic luxury items like lacquerwares, which were common commodities produced by skilled artisans and craftsmen.

The most common staple crops consumed during Han werewheat,barley,foxtail millet,proso millet,rice, andbeans.Commonly eaten fruits and vegetables included chestnuts, pears, plums, peaches, melons, apricots, strawberries,red bayberries,jujubes,calabash,bamboo shoots,mustard plant,andtaro.Domesticated animals that were also eaten included chickens,Mandarin ducks,geese, cows, sheep, pigs, camels, and dogs (various types were bred specifically for food, while most were used as pets). Turtles and fish were taken from streams and lakes. Commonly hunted game, such as owl, pheasant, magpie,sika deer,andChinese bamboo partridgewere consumed.Seasoning included sugar, honey, salt, andsoy sauce.Beer and wine were regularly consumed.

The types of clothing worn and the materials used during the Han period depended upon social class. Wealthy folk could afford silk robes, skirts, socks, and mittens, coats made of badger or fox fur, duck plumes, andslipperswith inlaid leather, pearls, and silk lining. Peasants commonly wore clothes made ofhemp,wool,andferretskins.

Families throughout Han China made ritual sacrifices of animals and food to deities, spirits, and ancestors attemples and shrines.They believed that these items could be used by those in the spiritual realm.It was thought that each person had atwo-part soul:the spirit-soul which journeyed to the afterlife paradise of immortals (xian), and the body-soul which remained in its grave or tomb on earth and was only reunited with the spirit-soul through a ritual ceremony.

In addition to his many other roles, the emperor acted as the highest priest in the land who made sacrifices to Heaven, themain deitiesknown as theFive Powers,and spirits of mountains and rivers known asshen.It was believed that the three realms of Heaven, Earth, and Mankind were linked by natural cycles ofyin and yangand thefive phases.If the emperor did not behave according to proper ritual, ethics, and morals, he could disrupt the fine balance of these cosmological cycles and cause calamities such as earthquakes, floods, droughts, epidemics, and swarms of locusts.

It was believed that immortality could be achieved if one reached the lands of theQueen Mother of the WestorMount Penglai.Han-era Taoists assembled into small groups of hermits who attempted to achieve immortality through breathing exercises, sexual techniques, and the use of medical elixirs.

By the 2nd century AD, Taoists formed large hierarchical religious societies such as theWay of the Five Pecks of Rice.Its followers believed that the sage-philosopherLaozi(fl. 6th century BC) was a holy prophet who would offersalvationand good health if his devout followers would confess their sins, ban the worship of unclean gods who accepted meat sacrifices, and chant sections of theTao Te Ching.

Buddhism first entered Imperial Chinathrough the Silk Roadduring the Eastern Han, and was first mentioned in 65 AD.Liu Ying(d. 71 AD), a half-brother toEmperor Ming of Han(r. 57–75 AD), was one of its earliest Chinese adherents, althoughChinese Buddhismat this point was heavily associated with Huang–Lao Taoism.China's first known Buddhist temple, theWhite Horse Temple,was constructed outside the wall of Luoyang during Emperor Ming's reign.Important Buddhist canons were translated into Chinese during the 2nd century AD, including theSutra of Forty-two Chapters,Perfection of Wisdom,Shurangama Sutra,andPratyutpanna Sutra.

Government and politics

Central government

In Han government, the emperor was the supreme judge and lawgiver, the commander-in-chief of the armed forces and sole designator of official nominees appointed to the top posts in central and local administrations; those who earned a600-bushel salary-rank or higher.Theoretically, there were no limits to his power.

However, state organs with competing interests and institutions such as the court conference (tingyiĐình nghị)—where ministers were convened to reach a majority consensus on an issue—pressured the emperor to accept the advice of his ministers on policy decisions.If the emperor rejected a court conference decision, he risked alienating his high ministers. Nevertheless, emperors sometimes did reject the majority opinion reached at court conferences.

Below the emperor were hiscabinetmembers known as theThree Councillors of State.These were theChancellororMinister over the Masses,the Imperial Counsellor or Excellency of Works (Yushi dafuNgự sử đại phuorDa sikongĐại Tư Không), and Grand Commandant or Grand Marshal (TaiweiThái úyorDa simaĐại tư mã).

The Chancellor, whose title had changed in 8 BC to Minister over the Masses, was chiefly responsible for drafting thegovernment budget.The Chancellor's other duties included managing provincial registers for land and population, leading court conferences, acting as judge in lawsuits, and recommending nominees for high office. He could appoint officials below the salary-rank of 600 bushels.

The Imperial Counsellor's chief duty was to conduct disciplinary procedures for officials. He shared similar duties with the Chancellor, such as receiving annual provincial reports. However, when his title was changed to Minister of Works in 8 BC, his chief duty became the oversight of public works projects.

The Grand Commandant, whose title was changed to Grand Marshal in 119 BC before reverting to Grand Commandant in 51 AD, was the irregularly posted commander of the military and then regent during the Western Han period. In the Eastern Han era he was chiefly a civil official who shared many of the same censorial powers as the other two Councillors of State.

Ranked below the Three Councillors of State were theNine Ministers,who each headed a specialized ministry. The Minister of Ceremonies (TaichangQuá thường) was the chief official in charge of religious rites, rituals, prayers, and the maintenance of ancestral temples and altars.The Minister of the Household (Guang lu xunQuang lộc huân) was in charge of the emperor's security within the palace grounds, external imperial parks, and wherever the emperor made an outing by chariot.

The Minister of the Guards (WeiweiVệ úy) was responsible for securing and patrolling the walls, towers, and gates of the imperial palaces.The Minister Coachman (TaipuThái bộc) was responsible for the maintenance of imperial stables, horses, carriages, and coach-houses for the emperor and his palace attendants, as well as the supply of horses for the armed forces.The Minister of Justice (TingweiĐình úy) was the chief official in charge of upholding, administering, and interpreting the law.The Minister Herald (Da hongluĐại hồng lư) was the chief official in charge of receiving honoured guests like nobles andforeign ambassadorsat court.

The Minister of the Imperial Clan (ZongzhengTông chính) oversaw the imperial court's interactions with the empire's nobility and extended imperial family, such as granting fiefs and titles.The Minister of Finance (da sìnongĐại tư nông) was thetreasurerfor the official bureaucracy and the armed forces who handled tax revenues and set standards for units of measurement.The Minister Steward (ShaofuThiếu phủ) served the emperor exclusively, providing him with entertainment and amusements, proper food and clothing, medicine and physical care, valuables and equipment.

Local government

The Han empire, excluding kingdoms and marquessates, was divided, in descending order of size, into political units ofprovinces,commanderies,andcounties.A county was divided into several districts (xiangHương), the latter composed of a group ofhamlets(li), each containing about a hundred families.

The heads of provinces, whose official title was changed from Inspector to Governor and vice versa several times during Han, were responsible for inspecting several commandery-level and kingdom-level administrations.On the basis of their reports, the officials in these local administrations would be promoted, demoted, dismissed, or prosecuted by the imperial court.

A governor could take various actions without permission from the imperial court. The lower-ranked inspector had executive powers only during times of crisis, such as raising militias across the commanderies under his jurisdiction to suppress a rebellion.

A commandery consisted of a group of counties, and was headed by an administrator.He was the top civil and military leader of the commandery and handled defence, lawsuits, seasonal instructions to farmers, and recommendations of nominees for office sent annually to the capital in a quota system first established by Emperor Wu.The head of a large county of about 10,000 households was called a Prefect, while the heads of smaller counties were called chiefs, and both could be referred to asmagistrates.A Magistrate maintained law and order in his county, registered the populace for taxation, mobilized commoners for annualcorvéeduties, repaired schools, and supervised public works.

Kingdoms and marquessates

Main article:Kings of the Han dynasty

Kingdoms—roughly the size ofcommanderies—were ruled exclusively by the emperor's male relatives as semi-autonomousfiefdoms.Before 157 BC, some kingdoms were ruled by non-relatives, granted to them in return for their services to Emperor Gaozu. The administration of each kingdom was very similar to that of the central government.Although the emperor appointed the Chancellor of each kingdom, kings appointed all the remaining civil officials in their fiefs.

However, in 145 BC, after several insurrections by the kings, Emperor Jing removed the kings' rights to appoint officials whosesalaries were higher than 400 bushels.The Imperial Counsellors and Nine Ministers (excluding the Minister Coachman) of every kingdom were abolished, although the Chancellor was still appointed by the central government.

With these reforms, kings were reduced to being nominal heads of their fiefs, gaining a personal income from only a portion of the taxes collected in their kingdom.Similarly, the officials in the administrative staff of a full marquess's fief were appointed by the central government. A marquess's chancellor was ranked as the equivalent of a county prefect. Like a king, the marquess collected a portion of the tax revenues in his fief as personal income.

Until the reign ofEmperor Jing of Han,the Han emperors had great difficulties controlling their vassal kings, who often switched allegiances to theXiongnuwhenever they felt threatened by imperial centralization of power. The seven years of Gaozu's reign featured defections by three vassal kings and one marquess, who then aligned themselves with the Xiongnu. Even imperial princes controlling fiefdoms would sometimes invite a Xiongnu invasion in response to the Emperor's threats. The Han moved to secure a treaty with the Xiongnu, aiming to clearly divide authority between them. The Han and Xiongnu now held one another out as the "two masters" with sole dominion over their respective peoples; they cemented this agreement with a marriage alliance (heqin), before eliminating the rebellious vassal kings in 154 BC. This prompted some of the Xiongnu vassals to swap allegiances to the Han, starting in 147. Han court officials were initially hostile to the idea of disrupting the status quo by expanding into Xiongnu territory in the steppe. The surrendered Xiongnu were integrated into a parallel military and political structures loyal to the Han emperor, a step toward a potential Han challenge to the superiority of Xiongnu cavalry in steppe warfare. This also brought the Han into contact with the interstate trade networks through the Tarim Basin in the far northwest, allowing for the Han's expansion from a regional state to a universalist, cosmopolitan empire achieved in part through further marriage alliances with theWusun,another steppe power.

Military

At the beginning of the Han, every male commoner aged twenty-three was liable forconscriptioninto the military. The minimum age was reduced to twenty following the reign ofEmperor Zhao(r. 87–74).Conscripted soldiers underwent one year of training and one year of service as non-professional soldiers. The year of training was spent in one of three branches of the armed forces:infantry,cavalry,ornavy.Prior to the abolition of much of the conscription system after 30 AD, soldiers could be called up for future service following the completion of their terms. They had to continue training regularly to maintain their skills, and were subject to annual inspections of their military readiness.The year of active service was served either on the frontier, in a king's court, or in the capital under the Minister of the Guards. A small professional army was stationed near the capital.

During the Eastern Han, conscription could be avoided if one paid a commutable tax. The Eastern Han court favoured the recruitment of a volunteer army.The volunteer army comprised the Southern Army (NanjunNam quân), while thestanding armystationed in and near the capital was the Northern Army (BeijunBắc quân).Led by Colonels (XiaoweiGiáo úy), the Northern Army consisted of five regiments, each composed of several thousand soldiers.When central authority collapsed after 189 AD, wealthy landowners, members of the aristocracy/nobility, and regional military-governors relied upon their retainers to act as their own personal troops.

During times of war, the volunteer army was increased, and a much larger militia was raised across the country to supplement the Northern Army. In these circumstances, a general (Gian gjunTướng quân) led adivision,which was divided intoregimentsled by a colonel or major (simaTư Mã). Regiments were divided intocompaniesand led by captains.Platoonswere the smallest units.

Economy

Main article:Economy of the Han dynasty

Currency

Gold coins from the Eastern Han

The Han dynasty inherited theban liangcoin type from the Qin. In the beginning of the Han, Emperor Gaozu closed thegovernment mintin favour of private minting of coins. This decision was reversed in 186 BC by his widowGrand Empress Dowager Lü Zhi(d. 180 BC), who abolished private minting.In 182 BC, Lü Zhi issued a bronze coin that was much lighter in weight than previous coins. This caused widespreadinflationthat was not reduced until 175 BC, when Emperor Wen allowed private minters to manufacture coins that were precisely 2.6 g (0.092 oz) in weight.

In 144 BC, Emperor Jing abolished private minting in favour of central-government and commandery-level minting; he also introduced a new coin.Emperor Wu introduced another in 120 BC, but a year later he abandoned theban liangsentirely in favour of thewuzhucoin, weighing 3.2 g (0.11 oz).Thewuzhubecame China's standard coin until theTang dynasty(618–907). Its use was interrupted briefly by several new currencies introduced during Wang Mang's regime until it was reinstated in 40 AD by Emperor Guangwu.

Since commandery-issued coins were often of inferior quality and lighter weight, the central government closed commandery mints and monopolized the issue of coinage in 113 BC. This central government issuance of coinage was overseen by theSuperintendent of Waterways and Parks,this duty being transferred to the Minister of Finance during the Eastern Han.

Taxation and property

Aside from the landowner'sland taxpaid in a portion of theircrop yield,thepoll taxandproperty taxeswere paid in coin cash.The annual poll tax rate for adult men and women was 120 coins and 20 coins for minors. Merchants were required to pay a higher rate of 240 coins.The poll tax stimulated a money economy that necessitated the minting of over 28,000,000,000 coins from 118 BC to 5 AD, an average of 220,000,000 coins a year.

The widespread circulation of coin cash allowed successful merchants to invest money in land, empowering the very social class the government attempted to suppress through heavy commercial and property taxes.Emperor Wu even enacted laws which banned registered merchants from owning land, yet powerful merchants were able to avoid registration and own large tracts of land.

The small landowner-cultivators formed the majority of the Han tax base; this revenue was threatened during the latter half of Eastern Han when many peasants fell into debt and were forced to work as farming tenants for wealthy landlords.The Han government enacted reforms in order to keep small landowner-cultivators out of debt and on their own farms. These reforms included reducing taxes, temporary remissions of taxes, granting loans, and providing landless peasants temporary lodging and work inagricultural coloniesuntil they could recover from their debts.

In 168 BC, the land tax rate was reduced from one-fifteenth of a farming household's crop yield to one-thirtieth,and later to one-hundredth of a crop yield for the last decades of the dynasty. The consequent loss of government revenue was compensated for by increasing property taxes.

The labour tax took the form of conscripted labour for one month per year, which was imposed upon male commoners aged fifteen to fifty-six. This could be avoided in Eastern Han with a commutable tax, since hired labour became more popular.

Private manufacture and government monopolies

A Han dynasty ironjipolearm and iron dagger

In the early Western Han, a wealthy salt or iron industrialist, whether a semi-autonomous king or wealthy merchant, could boast funds that rivalled the imperial treasury and amass a peasant workforce numbering in the thousands. This kept many peasants away from their farms and denied the government a significant portion of its land tax revenue.To eliminate the influence of such private entrepreneurs, Emperor Wu nationalized the salt and iron industries in 117 BC and allowed many of the former industrialists to become officials administering the state monopolies.By the Eastern Han, the central government monopolies were repealed in favour of production by commandery and county administrations, as well as private businessmen.

Liquorwas another profitable private industry nationalized by the central government in 98 BC. However, this was repealed in 81 BC and a property tax rate of two coins for every 0.2 litres (0.053 US gal) was levied for those who traded it privately.By 110 BC, Emperor Wu also interfered with the profitable trade in grain when he eliminated speculation by selling government stores of grain at a lower price than that demanded by merchants.Apart from Emperor Ming's creation of a short-lived Office for Price Adjustment and Stabilization, which was abolished in 68 AD, central-government price control regulations were largely absent during the Eastern Han.

The Han dynasty was a unique period in the development of premodern Chinese science and technology, comparable to the level ofscientific and technological growthduring theSong dynasty(960–1279).

Writing materials

In the 1st millennium BC, typical ancient Chinese writing materials werebronzeware,oracle bones,andbamboo slipsor wooden boards. By the beginning of the Han, the chief writing materials wereclay tablets,silk cloth, hemppaper,and rolled scrolls made from bamboo strips sewn together with hempen string; these were passed through drilled holes and secured with clay stamps.

The oldest known Chinese piece of hempen paper dates to the 2nd century BC.The standard papermaking process was invented byCai Lun(AD 50–121) in 105.The oldest known surviving piece of paper with writing on it was found in the ruins of a Hanwatchtowerthat had been abandoned in AD 110, inInner Mongolia.

Evidence suggests thatblast furnaces,that convert rawiron oreintopig iron,which can be remelted in acupola furnaceto producecast ironby means of acold blastandhot blast,were operational in China by the lateSpring and Autumn period(722–481 BC).Thebloomerywas non-existent in ancient China; however, the Han-era Chinese producedwrought ironby injecting excess oxygen into a furnace and causingdecarburisation.Cast iron and pig iron could be converted into wrought iron and steel using afiningprocess.

The Han dynasty Chinese used bronze and iron to make a range of weapons, culinary tools, carpenters' tools, and domestic wares.A significant product of these improved iron-smelting techniques was the manufacture of new agricultural tools. The three-legged ironseed drill,invented by the 2nd century BC, enabled farmers to carefully plant crops in rows instead ofsowingseeds by hand.The heavy mouldboard iron plough, also invented during the Han, required only one man to control it with two oxen to pull it. It had threeploughshares,a seed box for the drills, a tool which turned down the soil and could sow roughly 45,730 m²(492,200 sq ft) of land in a single day.

To protect crops from wind and drought, the grain intendant Zhao Guo (Triệu quá) created the alternating fields system (daitianfaĐại điền pháp) during Emperor Wu's reign. This system switched the positions of furrows and ridges between growing seasons.Once experiments with this system yielded successful results, the government officially sponsored it and encouraged peasants to use it.Han farmers also used the pit field system (aotianLõm điền) for growing crops, which involved heavily fertilized pits that did not require ploughs or oxen and could be placed on sloping terrain.In the southern and small parts of central Han-era China,paddy fieldswere chiefly used to grow rice, while farmers along theHuai Riverusedtransplantationmethods of rice production.

Timber was the chief building material during the Han; it was used to build palace halls, multi-story residential towers and halls, and single-story houses.Because wood decays rapidly, the only remaining evidence of Han wooden architecture is a collection of scattered ceramic roof tiles.The oldest surviving wooden halls in China date to the Tang dynasty.Architectural historian Robert L. Thorp points out the scarcity of Han-era archaeological remains, and claims that often unreliable Han-era literary and artistic sources are used by historians for clues about lost Han architecture.

Though Han wooden structures decayed, some Han dynasty ruins made of brick, stone, andrammed earthremain intact. This includes stone pillar-gates, brick tomb chambers, rammed-earthcity walls,rammed-earth and brickbeacontowers, rammed-earth sections of theGreat Wall,rammed-earth platforms where elevated halls once stood, and two rammed-earth castles inGansu.The ruins of rammed-earth walls that once surrounded the capitals Chang'an and Luoyang still stand, along with theirdrainage systemsof brick arches, ditches, and ceramicwater pipes.Monumental stone pillar-gates,twenty-nine of which survive from the Han period, formed entrances of walled enclosures at shrine and tomb sites.These pillars feature artistic imitations of wooden and ceramic building components such as roof tiles, eaves, andbalustrades.

Thecourtyard houseis the most common type of home portrayed in Han artwork.Ceramic architecturalmodels of buildings,like houses and towers, were found in Han tombs, perhaps to provide lodging for the dead in the afterlife. These provide valuable clues about lost wooden architecture. The artistic designs found on ceramic roof tiles of tower models are in some cases exact matches to Han roof tiles found at archaeological sites.

Over ten Han-era underground tombs have been found, many of them featuring archways,vaultedchambers, and domed roofs.Underground vaults and domes did not require buttress supports since they were held in place by earthen pits.The use of brick vaults and domes in aboveground Han structures is unknown.

From Han literary sources, it is known that wooden-trestlebeam bridges,arch bridges,simple suspension bridges,and floatingpontoon bridgesexisted during the Han.However, there are only two known references to arch bridges in Han literature.There is only one relief sculpture dated to the Han period that depicts an arch bridge; it is located in Sichuan province.

Undergroundmine shafts,some reaching depths over 100 m (330 ft), were created for the extraction of metal ores.Boreholedrilling andderrickswere used to liftbrineto iron pans where it was distilled into salt. The distillation furnaces were heated bynatural gasfunnelled to the surface throughbamboo pipelines.These boreholes perhaps reached a depth of 600 m (2000 ft).

Mechanical and hydraulic engineering

Han-era mechanical engineering comes largely from the choice observational writings of sometimes-disinterested Confucian scholars who generally considered scientific and engineering endeavours to be far beneath them.Professional artisan-engineers (Gian gThợ) did not leave behind detailed records of their work.Han scholars, who often had little or no expertise in mechanical engineering, sometimes provided insufficient information on the various technologies they described.Nevertheless, some Han literary sources provide crucial information.

For example, in 15 BC the philosopher and poetYang Xiongdescribed the invention of thebelt drivefor aquillingmachine, which was of great importance to early textile manufacturing.The inventions of mechanical engineer and craftsmanDing Huanare mentioned in theMiscellaneous Notes on the Western Capital.Around AD 180, Ding created a manually operated rotary fan used for air conditioning within palace buildings.Ding also usedgimbalsas pivotal supports for one of his incense burners and invented the world's first knownzoetropelamp.

Modern archaeology has led to the discovery of Han artwork portraying inventions which were otherwise absent in Han literary sources. As observed in Han miniature tomb models, but not in literary sources, thecrank handlewas used to operate thefansofwinnowing machinesthat separated grain fromchaff.Theodometercart, invented during the Han period, measured journey lengths, using mechanical figures banging drums and gongs to indicate each distance travelled.This invention is depicted in Han artwork by the 2nd century, yet detailed written descriptions were not offered until the 3rd century.

Modern archaeologists have also unearthed specimens of devices used during the Han dynasty, for example a pair of sliding metalcalipersused by craftsmen for making minute measurements. These calipers contain inscriptions of the exact day and year they were manufactured. These tools are not mentioned in any Han literary sources.

Thewaterwheelappeared in Chinese records during the Han. As mentioned by Huan Tanc. 20 AD,they were used to turn gears that lifted irontrip hammers,and were used in pounding,threshing,and polishing grain.However, there is no sufficient evidence for thewatermillin China until about the 5th century.TheNanyang CommanderyAdministrator, mechanical engineer, and metallurgistDu Shi(d. 38 AD) created a waterwheel-poweredreciprocatorthat worked thebellowsfor the smelting of iron.Waterwheels were also used to powerchain pumpsthat lifted water to raised irrigation ditches. The chain pump was first mentioned in China by the philosopher Wang Chong in his 1st-centuryLunheng.

Thearmillary sphere,a three-dimensional representation of the movements in thecelestial sphere,was invented in Han China by the 1st century BC.Using awater clock,waterwheel, and a series of gears, the Court AstronomerZhang Heng(78–139 AD) was able to mechanically rotate his metal-ringed armillary sphere.To address the problem of slowed timekeeping in thepressure headof the inflow water clock, Zhang was the first in China to install an additional tank between the reservoir and inflow vessel.

Zhang also invented a device he termed an "earthquake weathervane" (houfeng didong yiMáy đo địa chấn), which the British sinologist and historianJoseph Needhamdescribed as "the ancestor of allseismographs".This device was able to detect the exactcardinalor ordinal direction of earthquakes from hundreds of kilometres away.It employed aninverted pendulumthat, when disturbed by ground tremors, would trigger a set of gears that dropped a metal ball from one of eight dragon mouths (representing all eight directions) into a metal toad's mouth.The account of this device in theBook of the Later Handescribes how, on one occasion, one of the metal balls was triggered without any of the observers feeling a disturbance. Several days later, a messenger arrived bearing news that an earthquake had struck in Longxi Commandery (modern Gansu), the direction the device had indicated, which forced the officials at court to admit the efficacy of Zhang's device.

Mathematics

Further information:Chinese mathematics § Han mathematics

Three Han mathematical treatises still exist. These are theBook on Numbers and Computation,theZhoubi Suanjing,and theNine Chapters on the Mathematical Art.Han mathematical achievements include solving problems with right triangles,square roots,cube roots,andmatrix methods,finding more accurateapproximations for pi,providingmathematical proofof thePythagorean theorem,use of thedecimal fraction,Gaussian eliminationto solvelinear equations,andcontinued fractionsto find theroots of equations.

One of the Han's greatest mathematical advancements was the world's first use ofnegative numbers.Negative numbers first appeared in theNine Chapters on the Mathematical Artas blackcounting rods,where positive numbers were represented by red counting rods.Negative numbers were also used by the Greek mathematicianDiophantusaround AD 275, and in the 7th-centuryBakhshali manuscriptofGandhara,South Asia,but were not widely accepted in Europe until the 16th century.

The Han applied mathematics to various diverse disciplines. Inmusical tuning,Jing Fang(78–37 BC) realized that 53perfect fifthswas approximate to 31octaves.He also created amusical scaleof 60 tones, calculating the difference at¹⁷⁷¹⁴⁷⁄₁₇₆₇₇₆(the same value of53 equal temperamentdiscovered by the German mathematicianNicholas Mercator[1620–1687], i.e. 3⁵³/2⁸⁴).

Astronomy

Further information:Chinese astronomy

Mathematics were essential in drafting theastronomical calendar,alunisolar calendarthat used the Sun and Moon as time-markers throughout the year.During the spring and autumn periods of the 5th century BC, the Chinese established the Sifen calendar (Cổ bốn phần lịch), which measured thetropical yearat 365.25 days. This was replaced in 104 BC with the Taichu calendar (Quá sơ lịch) that measured the tropical year at365+385⁄1539(~ 365.25016) days and thelunar monthat29+43⁄81days.However, Emperor Zhang later reinstated the Sifen calendar.

Han dynasty astronomers madestar cataloguesand detailed records of comets that appeared in the night sky, including recording the appearance of the comet now known asHalley's Cometin 12 BC.They adopted ageocentric modelof the universe, theorizing that it was a sphere surrounding the Earth in the centre.They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, thatlunar eclipsesoccurred when the Earth obstructed sunlight falling onto the Moon, and that asolar eclipseoccurred when the Moon obstructed sunlight from reaching the Earth.Although others disagreed with his model, Wang Chong accurately described thewater cycleof the evaporation of water into clouds.

Cartography, ships, and vehicles

Evidence found in Chinese literature, and archaeological evidence, show thatcartographyexisted in China before the Han.Some of the earliest Han maps discovered were ink-penned silk maps found amongst theMawangdui Silk Textsin a 2nd-century BC tomb.The generalMa Yuancreated the world's first knownraised-relief mapfrom rice in the 1st century.This date could be revised if the tomb of EmperorQin Shi Huangis excavated and the account in theRecords of the Grand Historianconcerning a model map of the empire is proven to be true.

Although the use of thegraduated scaleandgrid referencefor maps was not thoroughly described until the published work ofPei Xiu(AD 224–271), there is evidence that in the early 2nd century, cartographer Zhang Heng was the first to use scales and grids for maps.

Han dynasty Chinese sailed in a variety of ships different from those of previous eras, such as thetower ship.Thejunkdesignwas developed and realized during the Han era. Junk ships featured a square-endedbowandstern,a flat-bottomedhullorcarvel-shapedhull with nokeelorsternpost,andsolid transverse bulkheadsin the place ofstructural ribsfound in Western vessels.Moreover, Han ships were the first in the world to be steered using arudderat the stern, in contrast to the simplersteering oarused for riverine transport, allowing them to sail on the high seas.

Although ox-carts and chariots were previously used in China, the wheelbarrow was first used in Han China in the 1st century BC.Han artwork of horse-drawn chariots shows that the Warring-States-Era heavy wooden yoke placed around a horse's chest was replaced by the softerbreast strap.Later, during theNorthern Wei(386–534), the fully developedhorse collarwas invented.

Medicine

Han-era medical physicians believed that the human body was subject to the same forces of nature that governed the greater universe, namely thecosmologicalcycles of yin and yang and thefive phases.Each organ of the body was associated with a particular phase. Illness was viewed as a sign thatqi,or vital energy, channels leading to a certain organ had been disrupted. Thus, Han-era physicians prescribed medicine that was believed to counteract this imbalance.

For example, since the wood phase was believed to promote the fire phase, medicinal ingredients associated with the wood phase could be used to heal an organ associated with the fire phase.Besides dieting, Han physicians also prescribedmoxibustion,acupuncture,andcalisthenicsas methods of maintaining one's health.When surgery was performed by the Chinese physicianHua Tuo(d. AD 208), he usedanesthesiato numb his patients' pain and prescribed a rubbing ointment that allegedly sped the process of healing surgical wounds.Whereas the physicianZhang Zhongjing(c. AD 150– c. 219) is known to have written theShanghan lun( "Dissertation on Typhoid Fever" ), it is thought that both he and Hua Tuo collaborated in compiling theShennong Ben Cao Jingmedical text.
