The Jin dynasty or the Jin Empire (; Chinese: 晉朝; pinyin: Jìn Cháo, sometimes distinguished
as the Sima Jin (司马晋) or Liang Jin) (两晋, "Two Jins") was a Chinese dynasty
traditionally dated from 266 to 420.
It was founded by Sima Yan, son of Sima Zhao, who was made Prince of Jin and posthumously
declared the founder of the dynasty.
It followed the Three Kingdoms period (220-280 AD), which ended with the conquest of Eastern
Wu by the Jin.
There are two main divisions in the history of the dynasty.
The Western Jin (266–316) was established as a successor state to Cao Wei after Sima
Yan usurped the throne, and had its capital at Luoyang or Chang'an (modern Xi'an); Western
Jin reunited China in 280, but fairly shortly thereafter fell into a succession crisis,
civil war, and invasion by the "Five Barbarians (Wu Hu)."
The rebels and invaders began to establish new self-proclaimed states in the Yellow River
valley in 304, inaugurating the "Sixteen Kingdoms" era.
These states immediately began fighting each other and the Jin Empire, leading to the second
division of the dynasty, the Eastern Jin (317–420) when Sima Rui moved the capital to Jiankang
(modern Nanjing).
The Eastern Jin dynasty was eventually overthrown by the Liu Song.
== History ==
Under the Wei, who dominated China's Three Kingdoms period, the Sima clan rose to prominence,
particularly after the 249 coup d'état at the Gaoping Tombs.
Sima Zhao assisted the throne in suppressing other rebellions, recovering Shu and capturing
Liu Shan in 263 and opposing Zhong Hui's rebellion the next year.
His ambitions for the throne remain proverbial in Chinese but he died before he could rise
higher than prince of Jin, a title named for the Zhou-era marchland and duchy around Shaanxi's
Jin River.
(He was granted the title as his ancestral home was located in Wen County within Jin's
former lands.)
=== Founding ===
The Jin dynasty was founded in AD 266 by Sima Yan, posthumously known as Emperor Wu (the
"Martial Emperor of Jin").
He forced Cao Huan's abdication but permitted him to live in honor as the Prince of Chenliu
and buried him with imperial ceremony.
The Jin dynasty conquered the Eastern Wu in 280, and united the country.
The period of unity was short-lived as the state was soon weakened by corruption, political
turmoil, and internal conflicts.
Sima Yan's son Zhong, posthumously known as Emperor Hui (the "Benevolent Emperor of Jin"),
was developmentally disabled.
=== Decline === Conflict over his succession in 290 expanded
into the devastating War of the Eight Princes.
The weakened dynasty was then engulfed by the Uprising of the Five Barbarians and lost
control of northern China.
Large numbers of Chinese fled south from the Central Plains; among other effects, these
refugees and colonizers gave Quanzhou's Jin River its name as they settled its valley
in Fujian.
The Jin capital Luoyang was captured by Liu Cong in 311.
Sima Chi, posthumously known as Emperor Huai (the "Missing Emperor of Jin"), was captured
and later executed.
His successor Sima Ye, posthumously known as Emperor Min (the "Suffering Emperor of
Jin"), was captured at Chang'an (present-day Xi'an) in 316 and also later executed.
=== Eastern Jin === The remnants of the Jin court fled to the
east, reestablishing their government at Jiankang within present-day Nanjing, Jiangsu.
Sima Rui, the prince of Langya (琅琊), was enthroned in 318, posthumously becoming known
as Emperor Yuan (the "First Emperor of the Eastern Jin").
The rival northern states, who denied the legitimacy of his succession, sometimes referred
to his state as "Langya".
At first, the southerners were resistant to the new ruler from the north.
The circumstances obliged the Emperors of Eastern Jin to depend on both local and refugee
gentry clans, the latter convinced the former of the emperor enjoying high prestige by showing
superficial respect to Rui, which was also the pinnacle of menfa politics (門閥政治),
Several immigrated gentry clans were very active and they grasped the national affairs:
Wang (王) clans from Langya and Taiyuan, Xie (謝) clan from Chenliu (陳留), Huan
(桓) clan from Qiao Commandery (譙郡) and Yu (庾) clan from Yingchuan (潁川).
The Emperors of Eastern Jin had limited power.
There was a prevalent remark that "王與（司）馬，共天下 (Wang Dao and the emperor Sima Rui, they dominate
the nation together)" among the people.
It is said that when Emperor Yuan was holding court, he even invited Dao to sit by himself
accepting jointly the congratulations from ministers, but Dao declined it.The local gentry
clans were at odds with the immigrated.
As such tensions increased, they loomed larger in Jin's domestic politics.
Two biggest ones of local clans: Zhou (周) clan from Yixing (義興) and Shen (沈) clan
from Wuxing (吳興)'s ruin was a bitter blow from which they never quite recovered.
Moreover, there was a conflict among the immigrated clans' interests, it was a faction led to
a virtual balance somewhat benefited the emperor's ruling.
Although there was a stated goal of recovering the "lost northern lands", paranoia within
the royal family and a constant string of disruptions to the throne caused the loss
of support among many officials.
Military crises—including the rebellions of the generals Wang Dun and Su Jun but also
lesser fangzhen (方鎮, "military county") revolts—plagued the Eastern Jin throughout
its 104 years of existence.
Special "commanderies of immigrants" and "white registers" were created for the massive amount
of northern origin Han Chinese who moved south during the Eastern Jin dynasty.
The southern Chinese aristocracy was formed from the offspring these migrants.
Celestial Masters and the nobility of northern China subdued the nobility of southern China
during the Eastern Jin and Western Jin in Jiangnan in particular.
The most populous region of China was southern China after the depopulation of the north
and the migration of northern Chinese to southern China.
Different waves of migration of aristocratic Chinese from northern China to the south at
different times resulted in distinct groups of lineages, with some lineages arriving in
the 300s-400s and others in the 800s-900s.The Eastern Jin recovered its unity in the face
of the 383 invasion by the Former Qin.
The short-lived coöperation among Huan Chong (brother of General Huan Wen) and Prime Minister
Xie An helped provide a major victory at the Fei River.
A large amount of Former Qin territory was then taken or retaken.
=== Demise === Later, Huan Xuan, Huan Wen's son, usurped
the throne and changed the dynasty's name to Chu.
He, in turn, was toppled by Liu Yu, who reinstated Sima Dezong, posthumously known as Emperor
An (the "Peaceful Emperor of Jin").
Meanwhile, as civilian administration suffered, there were further revolts led by Sun En and
Lu Xun; Western Shu became an independent kingdom under Qiao Zong.
Liu Yu had Sima Dezong strangled and replaced by his brother Sima Dewen, posthumously known
as Emperor Gong (the "Respectful Emperor of Jin"), in 419.
Sima Dewen abdicated in 420 in favor of Liu Yu, who declared himself the ruler of the
Song; he was asphyxiated with a blanket the following year.
In the north, Northern Liang, the last of the Sixteen Kingdoms, was conquered by the
Northern Wei in 439, ushering in the Northern dynasties period.
The Xianbei Northern Wei accepted the Jin refugees Sima Fei (司馬朏) and Sima Chuzhi
(司馬楚之).
They both married Xianbei princesses.
Sima Fei's wife was named Huayang (華陽公主), who was the daughter of Emperor Xiaowen; Sima
Chuzhi's son was Sima Jinlong (司馬金龍), who married a Northern Liang princess who
was a daughter of Xiongnu King Juqu Mujian.
Much later, Sima Guang (1019–1086), who served as prime minister to the Song, claimed
descent from the Jin dynasty (specifically, Sima Fu, brother of Sima Yi).
== Government and demography ==
=== Menfa politics ===
=== Qiaoren and baiji === The uprising of the five barbarians led to
one northerner in eight immigrated to the south.
These immigrants were called "qiaoren (僑人, literally the lodged people)" accounting for
one sixth the then people lived in the south.
Considering most property of these refugees had been lost or exhausted as they arrived,
they were privileged to be free from diao (調), a special poll tax was paid via the
silken or cotton cloth etc. in the ancient China, and service.
Their registers which bound in white papers were called baiji (白籍) in Chinese.
The ordinary ones which bound in yellow papers were called huangji (黃籍) in comparison.
Since situation settled down, the preferential treatment not only was the heavy burden for
the nation, but also aroused dissatisfaction from the natives.
Hence, tu duan was an increasingly important issue for the Eastern Jin.
=== Lodged administrative divisions in Jin dynasty ===
The Eastern Jin court established the lodged administrative divisions in where were strongholds
of qiaoren.
More effective in administration for them was a realistic starting point for that.
Consisting of three levels: qiaozhou (僑州, the lodged province), qiaojun (僑郡, the
lodged commandery) and qiaoxian (僑縣, the lodged county), these lodged administrative
divisions were merely nominal without possessing actual domain, or rather, they were local
government in exile, what could scarcely be denied was their significance of Jin's legitimacy
for the north territory as somewhat an announcement.
Furthermore, it was also an action to appease refugees' homesickness or home town complex,
evoking their desire to resume the lost.
During the Emperor Yuan, Emperor Ming and Emperor Cheng period, the lodged administrative
divisions were concentrated in the area south of the Huai River and the Lower Yangtze Plain.
At first there was the lodged Langya Commandery within lodged Fei County in Jiankang, but
when it began was not exact.
Then the lodged Huaide County was also established in Jiankang, around 320.
According to the Book of Song:晉永嘉大亂，幽、冀、青、並、兗州及徐州之淮北流民，相率過淮，亦有過江在晉陵郡界者……又徙流民之在淮南者于晉陵諸縣，其徙過江南及留在江北者，並立僑郡縣以司牧之。徐、兗二州或治江北，江北又僑立幽、冀、青、並四州……(After
Disaster of Yongjia, the refugees from You, Ji, Qing, Bing, Yan and Xu provinces came
across the Huai River, some even came across the Yangtze River and stayed in Jinling Commandery...
The lodged administrative divisions were established to govern them.
The seats of Xu and Yan provinces perhaps were moved to the area north of the Yangtze
River, where the lodged You, Ji, Qing, Bing provinces were established.)The lodged Pei,
Qinghe, Xiapi, Dongguang, Pingchang, Jiyin, Puyang, Guangping, Taishan, Jiyang, Lu commanderies
were stablished when Emperor Ming ruled.
The rebellions and invasions occurred in Jianghuai area led to more refugees switched to settle
in the south of the Yangtze River, where the lodged Huainan Commandery was established
afterwards.
However, carrying out was more complex than the policy was formulated.
Several actual counties were under the jurisdiction of the lodged commanderies.
A few lodged administrative divisions are still retained in China nowadays.
For instance, Dangtu County was originally located in the area of Bengbu, however the
lodged Dangtu County was established in where it is now, and the latter replaced the former,
inheriting its place name.
=== Tu duan policy in Jin dynasty === The tu duan (土斷) is the abbreviation for
yi tu duan (以土斷, means classifying people according to their present habitation to register).
It was a policy to ensure the ancient hukou system working since the Western Jin.
These terms were firstly recorded in the biographies of Wei Guan and Li Chong included in the Book
of Jin:今九域同規，大化方始，臣等以為宜皆蕩除末法，一擬古制，以土斷，定自公卿以下，皆以所居為正，無復懸客遠屬異土者。然承魏氏凋弊之跡，人物播越，仕無常朝，人無定處，郎吏蓄於軍府，豪右聚於都邑，事體駁錯，與古不同。謂九品既除，宜先開移徙，聽相並就。且明貢舉之法，不濫於境外，則冠帶之倫將不分而自均，即土斷之實行矣。Hence, it perhaps proposed initially by these two
persons, but was implemented seriously in the Eastern Jin and the Southern dynasties.
== Society and culture ==
=== Material culture ===
The Jin dynasty is well known for the quality of its greenish celadon porcelain wares, which
immediately followed the development of proto-celadon.
Jar designs often incorporated animal, as well as Buddhist, figures.Examples of Yue
ware are also known from the Jin dynasty.
=== Religion === Taoism was polarized in the Jin dynasty.
The Jin emperors repressed Taoists harshly, but also tried to exploit it, given the way
it had been used near the end of the Han era in the poor peasants' revolts.
Amidst the political turmoil of the era, many successful merchants, small landowners, and
other moderately comfortable persons found great solace in Taoist teachings and a number
of major clans and military officers also took up the faith.
Ge Hong emphasized loyalty to the emperor as a Taoist virtue; he even taught that rebels
could never be Taoist immortals, which made Taoism more palatable to the imperial hierarchy.
As a result, popular Taoist religions were considered heterodoxy while the official schools
of the court were supported, but the popular schools like Tianshi Taoism were still secretly
held dear and promulgated amongst ordinary people.
Disunity, disintegration, and chaos also made Buddhism more popular, in part due to the
focus on addressing suffering.
The Jin dynasty marked a critical era for Mahayana in China.
Dharmarakṣa’s translation of the Saddharmapundarika Sūtra was the most important sutra before
Kumārajīva’s Lotus Sutra.
It was said that there were 1,768 Buddhist temples in the Eastern Jin.Furthermore, Taoism
advanced chemistry and medicine in China, whereas the contribution of Mahayana was concentrated
in the philosophy and literature.
