* 325 – Crown Prince Jin Chengdi, age 4, succeeds his father Jin Mingdi as emperor of the Eastern Jin Dynasty.

** Emperor Ai of Jin, a Jin Dynasty ( 265-420 ) emperor

** Sima Ai, Jin Dynasty ( 265-420 ) imperial prince

Although the Three Kingdoms were reunified by the Jin Dynasty in 280, this structure was essentially the same until the Wu Hu uprising.

Taking advantage of civil war in the Jin Dynasty, the contemporary non-Han Chinese ( Wu Hu ) ethnic groups controlled much of the country in the early 4th century and provoked large-scale Han Chinese migrations to south of the Yangtze River.

Signaled by the collapse of East Jin Dynasty in 420, China entered the era of the Southern and Northern Dynasties.

Capitals: of the Song Dynasty, Kaifeng and Lin ' an ; of the Liao Dynasty, Shangjing, Nanjing, and Tokmok ; of the Jin Dynasty, Shangjing, Zhongdu, and Kaifeng ; of the Western Xia Dynasty, Yinchuan

In 1115, the Jurchen Jin Dynasty emerged to prominence, annihilating the Liao Dynasty in 10 years.

The Southern Song Dynasty also suffered the humiliation of having to acknowledge the Jin Dynasty as formal overlords.

In the ensuing years, China was divided between the Song Dynasty, the Jin Dynasty and the Tangut Western Xia.

This included the use of gunpowder weapons, which played a large role in the Song Dynasty naval victories against the Jin in the Battle of Tangdao and Battle of Caishi on the Yangtze River in 1161.

The Jurchen-founded Jin Dynasty was defeated by the Mongols, who then proceeded to defeat the Southern Song in a long and bloody war, the first war in which firearms played an important role.

Cavalry tactics in China were enhanced by the invention of the saddle-attached stirrup by at least the 4th century, as the oldest reliable depiction of a rider with paired stirrups was found in a Jin Dynasty tomb of the year 322 AD.

The Chinese tradition since the Jin Dynasty ( 3rd century AD ) that emperors of one dynasty would sponsor the writing of the official history of the immediately preceding dynasty has been cited in favor of an ethnically inclusive interpretation of history.

The first documented battlefield use of fire lances took place in 1132 when Chen Gui used them to defend De ' an from attack by the Jurchen Jin.

Liu Bian took the Han throne as Emperor Shao, and He Jin plotted with warlord Yuan Shao to assassinate the Ten Attendants, a clique of ten eunuchs led by Zhang Rang who controlled much of the imperial court.

Ultimately, Liu Yu's rise ended major chaos and later he took the throne for himself, marking the ending of the Jin Dynasty and the start of the Liu Song Dynasty, and the Southern and Northern Dynasties period of Chinese history.

In 1234, the Jin Dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song.

After Jin Dynasty attacked and took parts of the northern territories from the Song Dynasty, initiating the Southern Song period, Western Xia also attacked and took several thousands square miles of land.

People like Chen Duxiu and Li Dazhao shifted more to the Left and were among the leading founders of the 1921 Communist Party of China, whilst other intellectuals, such as the Anarchist writer and agitator, Ba Jin also took part in the movement.

The passage in the Jin Shu expanded upon this, explaining that it took a similar form to the mechanical device of the South Pointing Chariot invented by Ma Jun ( 200 – 265, see also differential gear ).

It only took a month until Jin Island fell to a combined Goryeo and Mongol army.

The army declined noticeably and had a difficult time facing some enemies: the Jin Chuan area took 2 – 3 years to conquer — at first the Qing army were mauled, though Yue Zhongqi later took control of the situation.

When Duke You of Jin ( 433-416 ) came to the throne the three clans took over much of the remaining Jin lands, leaving the dukes only the area around Jiang and Quwo.

He Jin took preemptive action and had Empress Dowager He issue an edict exiling her mother-in-law back to Hejian ( in modern Baoding, Hebei ), where her husband's fief was and Dong Chong arrested.

In light of these failures, Yang took another tack — he started a détente with Lu and treated the Eastern Wu border residents well, causing them to view Jin favorably.

In spring 317, his officials requested that he take the throne, and after he declined initially, he took the title " Prince of Jin " -- a title previously used by Sima Zhao while regent of Cao Wei — rather than emperor.

Three days later, Liu Yu took the throne and established Liu Song, ending Jin.

Heung Jin Nim swerved the car to prevent the two friends who were with him from taking the brunt of the impact, and instead took it on himself.

In fall 410, after Liu Yu had destroyed Southern Yan, Lu Xun took the opportunity to capture much of Jin territory, but then was forced to retreat when Liu Yu returned from his Southern Yan campaign.

During a preliminary round match against local wildcard Jin Long in the 2008 China Open, Harold, tiring rapidly after the long journey and gruelling battle locked at 4 – 4, took time out before the deciding frame to leave the playing arena and consume a couple of bananas, returning replenished to finish the job with a clearance on the colours.

The Battle of Chengpu () took place in 632 BC between the State of Jin and the State of Chu and its allies during the Spring and Autumn Period of Chinese history.

He Jin and his sister, now the Empress Dowager, jointly took on the role of regent.

He Jin took preemptive action and had Empress Dowager He issue an edict exiling her mother-in-law back to Hejian ( in modern Baoding, Hebei ), where her husband's fief was and Dong Chong arrested.

Jin Yong went on travel for a short period of time during the writing of the novel, so Ni Kuang took over the serialisation and made additions amounting to more than 40, 000 words.

The aggressive statesman Fan Sui ( 范雎 ), however, soon came to power as prime minister even as the problem of the succession was resolved, and he began an expansionist policy that had originated in Jin and Qi, which prompted the Qin to attempt to conquer the other states.

* January 8 – Emperor Jin Huidi dies after a 16-year reign in which eight dukes of the imperial family have conducted a civil war ( War of the Eight Princes ) against each other in a struggle for power.

* 636 BC — Duke Wen of Jin ascends to power in the State of Jin during the Zhou Dynasty of China.

Upon the advent of the second Jin emperor, Emperor Hui, various imperial princes tried to grab power in the devastating War of the Eight Princes.

The Emperors of Eastern Jin had limited power, with most of it concentrated in the royal family's hands, whilst military power was mostly wielded by non-royals.

That summer, Jin Emperor Xuānzōng ( 宣宗 ) abandoned the central capital and moved the government to the " southern capital " of Kaifeng, making it the official seat of Jin Dynasty power.

Although the Jin forces boasted 70, 000 men on 600 warships, and the Song forces only 3, 000 men on 120 warships, the Song Dynasty forces were victorious in both battles due to the destructive power of the bombs and the rapid assaults by paddle wheel ships.

Although the Song Dynasty was able to hold back the Jin, a new considerable foe came to power over the steppe, deserts, and plains north of the Jin Dynasty.

In 1616, Nurhaci broke away from the power of the decaying Ming Dynasty and established the Later Jin Dynasty ( Manchu :, Möllendorff: amaga aisin gurun ), domestically called the State of Manchu ( Manchu :, Möllendorff: manju gurun ), and unified Manchu tribes, establishing ( or at least expanding ) the Manchu Banner system, a military structure which made their forces quite resilient in the face of superior Ming Dynasty numbers in the field.

Fearing his growing power, the eunuchs led by Zhang Rang lure He Jin into the palace and murder him.

Amid the interstate power struggles, internal conflict was also rife: six elite landholding families waged war on each other in Jin ; the Chen family was eliminating political enemies in Qi ; and legitimacy of the rulers was often challenged in civil wars by various royal family members in Qin and Chu.

Over the next two centuries, the four most powerful states — Qin, Jin, Qi and Chu — struggled for power.

However, when Duke Wen of Jin ( r. 636 – 628 BC ) came to power, he capitalized on the reforms of his father, Duke Xian ( r. 676 – 651 BC ), who had centralized the state, killed off relatives who might threaten his authority, conquered sixteen smaller states, and even absorbed some Rong and Di peoples to make Jin much more powerful than it had been previously.

Duke Wen of Jin then used his growing power to coordinate a military response with Qi, Qin, and Song against Chu, which had begun encroaching northward after the death of Duke Huán of Qi.

After the death of Duke Wen in 628 BC, a growing tension manifested in interstate violence that turned smaller states, particularly those at the border between Jin and Chu, into sites of constant warfare ; Qi and Qin also engaged in numerous interstate skirmishes with Jin or its allies to boost their own power.

Amid conflict between Jin and Chu, Wu in modern-day Jiangsu and Yue in modern-day Zhejiangtwo coastal states with dubious Zhou tiesgrew in power as they gained relevance in interstate affairs.

After the great age of Jin power, the Jin dukes began to lose authority over their nobles.
