The military history of the Northern and Southern dynasties encompasses the period of Chinese military activity from 420 to 589. Officially starting with Liu Yu's usurpation of the Jin throne and creation of his Liu Song dynasty in 420, it ended in 589 with the Sui dynasty's conquest of Chen dynasty and reunification of China. The first of the Northern dynasties did not however begin in 420, but in 386 with the creation of Northern Wei. Thus there is some unofficial overlap with the era of the Sixteen Kingdoms.
During the Eastern Jin period, the army relied on a system of hereditary military households for recruitment. However, having lost the resources of the north, the Eastern Jin army attempted to bolster the number of military families in the south by incorporating convicts, vagrants, and aboriginals. This resulted in a general decline of social status and morale in the military. By the end of the dynasty, military men were regarded little better than government slaves. Terms of service were exceedingly harsh. One in three men from a military family was called upon for a term of service lasting from the age of 15 to their 60s. Essentially their entire life. Those who suffered debilitating injuries had to find a replacement from their family to procure release. Desertion was rampant and exit from the military household system a much sought after reward. By the sixth century the system of hereditary military households had collapsed.
During the Liu Song dynasty, voluntary recruits began to supplant the defunct military caste system. Many of these soldiers were former members of the previous system who had been freed, and had chosen to re-enlist for better terms, or because they could find no better employment. In practice, many of the military communities which had sprung up during the era of hereditary troops stayed together, and provided the basis for recruitment for the next dynasty. By the Liang and Chen dynasties, voluntary recruits had become the dominant component of the military.
Commoners were sometimes called up during times of special need, however their service was generally relegated to labor or logistical duties. Military commanders of the time had little faith in their fighting ability.
After Northern Wei shifted its capital to Luoyang, the lower class Xianbei were registered as "garrison households". These functioned similarly to the southern hereditary military households and were used for frontier garrison posts. They were excluded from the formal ranking system. After the collapse of Northern Wei, the Eastern Wei regime absorbed the greater portion of North Asian warriors and preferred to deploy them over the Han Chinese. The Western regime lacked the manpower to forego Han Chinese recruits and made significant use of them in their campaigns.
The primary significance of the Twenty-four Armies was that Yuwen Tai had managed to bolster his forces to a size far beyond what he originally started with. From 50,000 men in 550, the Twenty-four Armies had doubled in size by 570. It's not certain how this happened and the specifics are still a source of contention. The general view is that to create the Twenty-four Armies, the Western Wei government implemented a system of mass recruitment. However, unlike the conscription of the Han dynasty, this time the government provided new incentives by removing the names of recruits from the household registers. This meant that they were effectively free from normal tax and labor obligations. It was said that "after this half the Chinese became soldiers".
The utilization of Chinese troops eventually led to the triumph of Northern Zhou over Southern Qi. Despite having a larger population base, the eastern Xianbei elite hailed from the northern garrisons which opposed sinicizing policies at the capital. They treated the Chinese with disdain and distrust, refusing to incorporate them into their military structure. The Chinese population reciprocated this sentiment and did little to help their overlords in times of need. In the west, the Xianbei had no choice but to rely upon not just the Chinese, but also the Qiang, for they lacked the numbers to stand up to their eastern counterpart. The result was a new hybridized northwestern aristocracy of Xianbei, Chinese, and Qiang descent that gave birth to the Sui and Tang dynasties.
During the Northern and Southern dynasties period (420-589), a style of armour called "cord and plaque" became popular, as did shields and long swords. "Cord and plaque" armour consisted of double breast plates in the front and back held in position by two shoulder straps and waist cords, in conjunction with the usual lamellar armour. "Cord and plaque" wearing figurines are also often depicted holding an oval or rectangular shield and a long sword. Types of armour had also apparently become distinct enough for there to be separate categories for light and heavy armour.
In the 6th century, Qimu Huaiwen introduced to Northern Qi the process of 'co-fusion' steelmaking, which used metals of different carbon contents to create steel. Apparently sabers made using this method were capable of penetrating 30 armour lamellae. It's not clear if the armour was of iron or leather.
Huaiwen made sabres [dao 刀] of 'overnight iron' [su tie 宿鐵]. His method was to anneal [shao 燒] powdered cast iron [sheng tie jing 生鐵精] with layers of soft [iron] blanks [ding 鋌, presumably thin plates]. After several days the result is steel [gang 剛]. Soft iron was used for the spine of the sabre, He washed it in the urine of the Five Sacrificial Animals and quench-hardened it in the fat of the Five Sacrificial Animals: [Such a sabre] could penetrate thirty armour lamellae [zha 札]. The 'overnight soft blanks' [Su rou ting 宿柔鋌] cast today [in the Sui period?] by the metallurgists of Xiangguo (襄國) represent a vestige of [Qiwu Huaiwen's] technique. The sabres which they make are still extremely sharp, but they cannot penetrate thirty lamellae.
Northern Wei (386–535)Edit
End of the Sixteen KingdomsEdit
From 388–9, he established dominion over the Kumoxi, Jieru, and Tutulin in the east. From 390–1, he defeated the Gaoju, Yuange, Helan, Gexi, Getulin, Chinu, and Chufu north of the Yellow River. From 391–2, he defeated the Xiongnu south of the Yellow River.
In the summer of 395, the heir apparent of Later Yan, Murong Bao, attacked Northern Wei. Tuoba Gui chose not to confront him head on and fled west across the Yellow River, leaving the east undefended. When Murong Bao reached the east bank of the Yellow River, a series of protracted skirmished occurred, lasting until winter. At that point Murong Bao started to retreat, but Tuoba Gui overtook him with a column of cavalry at Shenhe Slope, northwest of modern Horinger. The entire Yan army was taken by surprise and routed on 8 December 395. Murong Chui led a new invasion into Later Yan territory in 396 and defeated an army near Pingcheng, but the offensive came to an abrupt halt when he grew ill and died. The momentum reversed and Yan armies captured Bing Province in the fall, Zhongshan in 397, and Ye city in 398.
Tuoba Gui died in 409 and was succeeded by his son, Tuoba Si, posthumously Emperor Mingyuan of Northern Wei. Tuoba Si was heavily involved in Chinese poetry and literature and lacked the martial drive of his predecessor. Under his reign, there were two campaigns against the Rouran to the north.
Tuoba Si died in 423 and was succeeded by his son Tuoba Tao, posthumously Emperor Taiwu of Northern Wei. Tuoba Tao was the polar opposite of his father. According to Sima Guang, the heir of Tuoba Si was courageous and stalwart, often leading the charge in assaulting heavily defended cities, and acted indifferently towards the sight of death. In 426 he attacked the kingdom of Xia, taking Chang'an and Tongwancheng in 427. However Chang'an was retaken the next year. In 430 Northern Wei took Luoyang from the Liu Song dynasty, conquered Northern Yan in 436, and Northern Liang in 439. Thus ended the Sixteen Kingdoms.
After conquering Northern Liang, Tuoba Tao crushed the rebellion of Ge Wu in Guanzhong and at the suggestion of Cui Hao, instigated proscription campaigns against Buddhism. In 449, he crushed the Rouran in battle and retaliated against a Liu Song invasion with his punitive expedition, reaching as far as Guabu (southeast of Luhe, Jiangsu). He was killed in 452 by a eunuch, Zong Ai, who was killed by Lu Li and others. They installed Tuoba Jun, posthumously Emperor Wencheng of Northern Wei.
In 465, Tuoba Jun died and was succeeded by Tuoba Hong, posthumously Emperor Xianwen of Northern Wei. Under his reign, Northern Wei invaded the Liu Song dynasty and Qingzhou and Jizhou (冀州) (north Jiangsu).
In 471, Tuoba Hong abdicated in favor of Yuan Hong, posthumously Emperor Xiaowen of Northern Wei. Hong's reign saw increasing sinicization at the court. In 494, Hong secretly moved the court to Luoyang under the disguise of a campaign. In 495, he banned the Xianbei language at court. Non-Chinese languages were forbidden for all officials under the age of 30 and Xianbei surnames were replaced with Chinese names: Tuoba became Yuan. Xianbei clothing was also forbidden. Xianbei ranks were subsumed under the Chinese ones, and all Xianbei families were ranked using the new system. In 496, Xianbei nobles and generals rebelled in the north but were defeated. Even Hong's own son opposed the new policies, for which he was forced to commit suicide.
In 499, Tuoba Hong died and was succeeded by Yuan Ke, posthumously Emperor Xuanwu of Northern Wei. Under Yuan Ke, Northern Wei invaded the Liang dynasty and conquered Yiyangin 504 and Chouchi in 506. They were however defeated at Zhongli (northeast of Fengyang, Anhui). A Liang counterattack saw the loss of Qushan (southwest of Lianyungang, Jiangsu) in 512.
in 515, Yuan Ke died and was succeeded by Yuan Xu, posthumously Emperor Xiaoming of Northern Wei.
In 523, drought and famine afflicted the northern frontier. Garrison commanders refused to distribute rations, causing the Six Frontier Towns to rebel under Poliuhan Baling. He was soon defeated with the aid of the Rouran khan Yujiulü Anagui, but northern refugees entered Hubei and also rebelled under Du Luozhou and Ge Rong.
In 528, Yuan Xu was poisoned by her mother and died. Erzhu Rong, a Jie general, took control of the capital and killed the empress and her son, Yuan Zhao. He enthroned Yuan Ziyou, posthumously Emperor Xiaozhuang of Northern Wei. Then with only 7,000 cavalry, Erzhu defeated Ge Rong's rebels. He enlisted the surrendered into his army, becoming the de facto ruler of Northern Wei. His victory was short lived, and Yuan Ziyou killed him in an ambush in 530. Erzhu Rong's heir, Erzhu Zhao, retaliated by sacking the capital and killing the emperor, replacing him with Yuan Ye. Erzhu Zhao failed to command his predecessor's former troops and they defected to Gao Huan.
In 531, Gao Huan established an independent regime in Hebei. Being a Chinese raised in the Xianbei culture, he commanded not only the loyalty of Xianbei frontiersmen, but also that of the Han Chinese. With his supporters, Gao decisively defeated Erzhu Zhao in late spring of 532. He enthroned Yuan Xiu, posthumously Emperor Xiaowu of Northern Wei.
In 534, Yuan Xiu fled to Chang'an under the regime of Yuwen Tai. In response, Gao Huan evicted Luoyang of its entire population and moved them to Ye city. Yuan Shanjian, posthumously Emperor Xiaojing of Eastern Wei, was enthroned under the eastern regime.
Western and Eastern WeiEdit
In 537, Gao Huan launched a three pronged attacked on Western Wei. When one column was crushed by a concentration of 6,000 cavalry under Yuwen Tai, Gao retreated. Gao made a second attempt with a force of 100,000. The resulting Battle of Shayuan on 19 November saw Gao's entire force defeated in a surprise ambush by 7,000 heavy cavalry. The eastern army lost more than half its men.
In 543, Yuwent Tai tried to take Luoyang again and failed.
In 546, Gao Huan tried to take Yubi again. He failed and died a few weeks later.
Gao’s men began by building an earthen mound to overlook the south wall of the fortress, but the defenders were able to counter by adding to the height of their towers. The attackers then tried tunnelling, but the defenders intercepted the tunnels by digging a deep trench inside and parallel to the south wall. When the attackers tried to weaken the wall with a sort of battering ram, the defenders lowered a cloth screen from the top of the wall to soften its impact. Gao Huan’s men eventually succeeded in undermining the wall and causing a small section to collapse, but the Western Wei defenders quickly filled the gap with a makeshift palisade. After spending thousands of lives to no avail, Gao abandoned the siege and withdrew to Taiyuan. He died only a few weeks later.— David Graff
In 556, Yuwen Tai died.

Northern Qi (550–577)Edit
On 10 November 576, Northern Zhou struck at Pingyang with an army of 145,000. With 60,000, the emperor took the city. As Gao Wei approached Pingyang, the enemies retreated with only 10,000 remaining in the city. On 10 January, 577, Northern Zhou returned with 80,000 men deployed in battle formation covering a wide perimeter. Gao Wei decided to engage the enemy army. When his left wing showed signs of collapsing, he fled, demoralizing his army and causing it to collapse. The Zhou army continued to advance, reaching Taiyuan on 17 January. On the 20th, 40,000 troops sallied out and were defeated. While they were retreating back into the city, the Zhou army scaled the walls. A Qi counterattack that night pushed back the invaders. On 21 January, the Zhou army breached the eastern gate and took the city. On 22 February 577, Ye city fell the Zhou. Gao Wei was captured and killed in 578.

Northern Zhou (557–581)Edit
Northern Zhou was founded by Yuwen Hu in 557. However Yuwen Hu never became emperor, instead placing Yuwen Jue on the throne, posthumously Emperor Xiaomin of Northern Zhou. Yuwen Jue tried to size power from Yuwen Hu, so Yuwen Hu had him killed and replaced with Yuwen Yu, posthumously Emperor Ming of Northern Zhou.
In 572, Yuwen Yong killed Yuwen Hu and seized complete power over the dynasty.
On 10 November 576, Northern Zhou struck at Pingyang with an army 145,000. With 60,000, the emperor took the city. As Gao Wei approached Pingyang, the enemies retreated with only 10,000 remaining in the city. On 10 January, 577, Northern Zhou returned with 80,000 men deployed in battle formation covering a wide perimeter. Gao Wei decided to engage the enemy army. When his left wing showed signs of collapsing, he fled, demoralizing his army and causing it to collapse. The Zhou army continued to advance, reaching Taiyuan on 17 January. On the 20th, 40,000 troops sallied out and were defeated. While they were retreating back into the city, the Zhou army scaled the walls. A Qi counterattack that night pushed back the invaders. On 21 January, the Zhou army breached the eastern gate and took the city. On 22 February 577, Ye city fell the Zhou. Gao Wei was captured and killed in 578.

In 587, the Sui dynasty annexed Western Liang and invaded the Chen dynasty with 518,000 men the following year. The Sui army took Jiankang in 589, annexing Chen and ending the era of Northern and Southern dynasties.
Liu Song (420–479)Edit
In 420, Liu Yu, posthumously Emperor Wu of Liu Song, usurped the Jin throne and replaced it with his own Liu Song dynasty. Liu Yu was originally the son of a low ranking official and his family was described as "poor". During the waning years of the Jin dynasty, Liu Yu proved himself to be an exceptionally capable commander, gifted in the use of the glaive, and worked his way up the military hierarchy. By the year 420, Liu Yu had become the dominant military power in the empire.
In 450, Song invaded Northern Wei but was defeated.
In 453, Liu Yilong was murdered by Liu Shao, who was then killed by Liu Jun, posthumously Emperor Xiaowu of Liu Song. Liu Jun spent his reign killing his brothers and checking the power of his kin.
In 464, Liu Jun died, sparking a civil war.
In 477, Liu Yu was killed by Xiao Daocheng and was succeeded by Liu Zhun, posthumously Emperor Shun of Liu Song. Xiao Daocheng went to war with provincial governor Shen Youzhi, eventually winning the next year.
Southern Qi (479–502)Edit
The Southern Qi dynasty founded by Xiao Daocheng in 479 lasted a mere 22 years. Xiao Daocheng died in 482 and was succeeded by Xiao Ze, posthumously Emperor Wu of Southern Qi. Xiao Ze died in 482 and was succeeded by Xiao Zhaoye. Xiao Luan assassinated him in 494 and became emperor, posthumously Emperor Ming of Southern Qi. When Xiao Luan died in 498 and Xiao Baojuan came to the throne, a series of plots and revolts by regional governors occurred. In 500, an imperial cousin named Xiao Yan raised 30,000 infantry and 5,000 cavalry in revolt. Northern Wei also invaded at this point and took territory south of the Huai River. In 501, Xiao Baojuan's subordinates killed him and surrendered Jiankang to Xiao Yan. In 502, Xiao Yan proclaimed himself Emperor of the Liang dynasty, posthumously Emperor Wu of Liang.
The Liang dynasty founded by Xiao Yan in 502 survived for 55 years, with the founder ruling for 48 of those years. To fund the state treasury, the emperor donated himself to a Buddhist monastery on three occasions and forced his ministers to pay a ransom for him each time.
In 551, Hou Jing killed Xiao Gang and declared himself emperor.
In 552, Wang Sengbian and Chen Baxian retook Jiankang while Hou Jing was killed. Xiao Ji declared himself emperor in Jiangling but was killed the next year. Xiao Yi became emperor, posthumously Emperor Yuan of Liang.
In 554, Xiao Yi was captured by Western Wei and killed.
