The Sixteen Kingdoms (simplified Chinese: 十六国; traditional Chinese: 十六國; pinyin: Shíliù Guó), less commonly the Sixteen States, was a period in Chinese history from AD 304 to 439 when the political order of the Jin dynasty (266–420) in northern China fragmented into a series of short-lived dynastic states. Most of these states were founded by the "Five Barbarians" – Xiongnu, Xianbei, Di, Jie, Qiang – non-Han peoples from northern and western China who launched the rebellions that toppled the Jin court in Luoyang in 311 and Chang'an (modern-day Xi'an) in 316, ending the Western Jin dynasty (266–316). Some of these peoples, notably the Xiongnu of Shanxi and the Di of Guanzhong had lived in China for generations and were highly sinicized. Others such as the Tuoba and Murong Xianbei tribes migrated from China's periphery into Central Plains in the ensuing decades to compete for political supremacy over northern China. All of these states took on Han-style dynastic names and most claimed as having the Mandate of Heaven to rule all of China. They frequently fought against one another and the Jin, which continued to rule southern China from Jiankang (modern-day Nanjing) as the Eastern Jin dynasty (317-420).
Due to fierce competition among the states and internal political instability, the kingdoms of this era were mostly short-lived. For seven years from 376 to 383, the Former Qin unified all of northern and northwest China and Sichuan. The Former Qin's quest to conquer southern China was stopped by the Eastern Jin at the Battle of Fei River (in modern-day central Anhui), after which the Former Qin splintered and northern China experienced even greater political fragmentation, with as many as nine states co-existing in the north in 400. This period ended with the unification of northern China in 439 by the Northern Wei, a dynasty established by the Xianbei Tuoba clan, and the history of northern China entered the Northern Dynasties period.
The Sixteen Kingdoms marked the first time in the imperial era of Chinese history that non-Han rulers governed a vast portion of the Chinese heartland and ruled as Emperor of China. Each of the northern kingdoms, regardless of the ethnicity of its founders and rulers, was multi-ethnic in character, and their rulers were sinicized to varying degrees, adopting a diversity of approaches to governance that drew on different mixes of Han and non-Han institutions and customs. The challenges that these rulers confronted — how to govern both Han and non-Han peoples, the degree to which they should adopt Chinese culture, and how in doing so they redefined what it meant to be Chinese — would persist through the subsequent Northern and Southern dynasties period, from which emerged the Sui and Tang dynasties with their more inclusive governance, multi-ethnic character and cosmopolitan culture.
The fall of the Western Jin dynasty amidst the rise of non-Han regimes in northern China during the Sixteen Kingdoms period resembles the fall of the Western Roman Empire amidst invasions by the Huns and Germanic tribes in Europe, which also occurred in the 4th to 5th centuries. While the division of Roman empire in 395 AD became permanent, China was able to reunify by integrating the barbarians from the Sixteen Kingdoms era into government and society. The broader dynamic of non-Chinese rulers adapting their rule to China would recur with the Liao, Jin (1115–1234), Yuan and Qing dynasties and continue to shape Chinese history into the early 20th century.
Period Name and Constituent Kingdoms
The term "Sixteen Kingdoms" was first used by the 6th-century historian Cui Hong in the Spring and Autumn Annals of the Sixteen Kingdoms, a compilation of available records from the states that appeared during the period. These were the five Liangs (Former, Later, Northern, Southern and Western), four Yans (Former, Later, Northern, and Southern), three Qins (Former, Later and Western), two Zhaos (Han/Former and Later), Cheng-Han and Xia.
Several other states from this period Cui Hong did not include Duan Qi, Western Yan, Ran Wei, Zhai Wei, Chouchi, and Tuyuhun. Nor did he include the Dai whose successor the Northern Wei, unified northern China and became the first of the Northern dynasties. The history of the Dai and Northern Wei is found in a later record, the Book of Wei.
Also excluded from the historiography are the short-lived regimes that broke away from the Eastern Jin after the dynasty was reconstituted in southern China. Regimes such as Huan Chu and Qiao Shu emerged from political turmoil within the Eastern Jin court.

History
Background
Since the Western Han dynasty (202 BC–9 AD), the non-Han peoples of the northern steppe and western highlands had been resettling into northern China. Along the frontiers in the north, the Chinese court employed a policy of recruiting surrendered tribes to serve as auxiliaries to defend against attacks from nomadic enemies, such as the Xianbei confederation. The Wuhuan tribes submitted as Chinese tributaries in the northeast, and in 50 AD, the Eastern Han dynasty (25–220) established the Southern Xiongnu vassal state in northern Bing province. In the northwest, western herders known as the Qiang and Di were brought in, predominantly to work as farmers and slaves in the Guanzhong basin. As migrants, these people lived among the ethnic Han and were sinicized to different degrees while retaining their tribal affiliations. However, they also faced discrimination and oppression, leading to racial tension and frequent rebellions.
The chaos that followed the fall of Eastern Han (189–220) and the Three Kingdoms period (220–280) brought the non-Han people even closer to the Chinese heartlands. After revolting and murdering their pro-Han chanyu in 189, the Southern Xiongnu tribes dissolved their government and dispersed throughout Bing province. Several frontier commanderies in Bing had to be abandoned, but the region corresponding with modern-day Shanxi was retained, where the remaining Xiongnu were reorganized into the Five Divisions near Taiyuan Commandery. The Wuhuan also mutinied around this time, but were decisively defeated and relocated to areas more to the south. The Xianbei, following the collapse of their own confederation, took advantage of the Wuhuan's decline to settle down along the northern and northeastern frontiers, with tribes such as the Tuoba and Murong pledging vassalage to the Chinese dynasties. In the northwest, the population of the Qiang, Di and other non-Han groups continued to swell, supplemented by the arrival of other Xianbei tribes. By the late 3rd-century, the population of the tribes in the Guanzhong and Shanxi had swelled, prompting some Chinese officials to advocate for their repatriation beyond the borderland.
Despite efforts to appease and punish, disparity between the ethnic Han and tribes persisted into the Western Jin period (266–316). The War of the Eight Princes (291–306) during the reign of the Emperor Hui of Jin severely weakened and divided imperial authority. Corruption was rampant among the Chinese elites and administrators, and popular rebellions against heavy taxation and repression erupted throughout the country. As the Jin princes exhausted the imperial army with their civil wars, they turned to the frontier auxiliaries as their source of military power, placing the tribes in prime position to exploit the chaos.
The beginning of the Sixteen Kingdoms period is often considered to be 304 AD. That year, as part of a rebellion that began back in 301, Li Xiong, a Ba-Di chieftain and refugee from the Guanzhong, formally claimed the imperial title of King and formed his state of Cheng-Han (304–347) in Sichuan, notably becoming the only state among the Sixteen Kingdoms to be based in southwestern China. Most of the later states were also founded by non-Han leaders whose family had lived in China for generations or were in the process of sinicization, and they are collectively known in historiography as the "Five Barbarians".
Fall of Western Jin to the Han-Zhao (304–318)
During the Jin civil wars, Liu Yuan, a noble from the Five Divisions and a descendant of the Southern Xiongnu chanyu, was serving as a general for one of the princes. The Five Divisions plotted to take advantage of the disorder by staging a revolt with Liu Yuan as their leader. After convincing his prince that he would rally his people to fight for his side, Liu Yuan was allowed to return home to Shanxi, and upon his arrival, he rebelled and openly declared his intent to restore the fallen Han dynasty. His regime, later renamed Zhao, is designated by historians as the Han-Zhao (304–329).
By the end of the War of the Eight Princes in 306, the Jin military in northern China had become severely weakened and ineffective in dealing with the various uprisings led by both the Han Chinese and the tribes. Many of these rebel groups, aggrieved by the civil wars and ongoing famines, flocked to join the Han-Zhao and soon encroached on the Chinese capital of Luoyang. In 311, less than a year after the ascension of Liu Cong to the Han throne, his forces annihilated the Jin imperial army and captured Luoyang along with Emperor Huai in the Disaster of Yongjia. In 316, the Western Jin came to an end after Liu Cong's cousin Liu Yao seized Chang'an and Emperor Min, though pockets of Jin resistance continued to resist in the north. In the south, where the regions were mostly unaffected by the chaos in the north, the prince, Sima Rui claimed the imperial title at Jiankang, preserving the dynasty as the Eastern Jin (318–420).
Rise and fall of Later Zhao (318–351)
After Liu Cong's death in 318, a failed coup was launch which saw his successor and most of the Han imperial family wiped out. The empire soon split between Liu Yao in the west and the powerful general, Shi Le in the east. Shi Le was an ethnic Jie, a group that emerged from the Southern Xiongnu in Bing province. Their exact origins is still disputed, with some theorizing that they were of Central Asian stock whose ancestors became subordinate tribes to the Xiongnu Shi Le initially worked as an indentured farm laborer before joining Liu Yuan's rebellion, and during his stint as a Han general, he gained considerable power over the Hebei region, ruling in all but name. In 319, he founded the Later Zhao (319–351), and after a decade-long confrontation, he decisively defeated Liu Yao at the Battle of Luoyang and destroyed the Han-Zhao in 329, placing most of northern China under his control.
To consolidate his rule, Shi Le reinforced the dual-system of government introduced by the Han-Zhao to impose separate governance for the Chinese and non-Chinese. After he died, his adoptive brother, Shi Hu seized the throne from his son in 334 and ruled the empire for the next 15 years. Shi Hu was described by records as a cruel and tyrannical ruler, especially towards the common Han Chinese people. On the other hand, he supported the proliferation of Buddhism in the north. He employed the Kuchean monk, Fotu Cheng as one of his chief court advisors, allowing him to spread his teachings among the common people and build hundreds of monastries. Shi Hu maintained a stalemate with the Eastern Jin and other neighbouring states, unable to make significant gains from his military campaigns. After his death in 349, his family members engaged in a fratricidal succession for the throne, culminating in his adopted Han Chinese grandson, Ran Min, seizing the government and carrying out a large-scale ethnic cleansing of the Jie people. The Later Zhao was soon destroyed by Ran Min in 351.
During the fall of Western Jin, some Chinese officials opted to find refuge in the farthest reaches of northern China, which later remained largely independent from Later Zhao control. In Gansu, the Chinese provincial inspector, Zhang Gui and his family governed the region as early as 301 and continued to do so long after the Western Jin's demise. Though they outwardly remained loyal to the Eastern Jin and never claimed the imperial title (with the exception of Zhang Zuo), their remoteness from the southern court allowed them to self-govern without much intervention, so historiography often refer to them as a sovereign regime known as the Former Liang (301–376). The Former Liang preserved much of Han literati culture in the north and expanded their influence into the Western Regions.
Around the Liao river basin, the Murong clan of Xianbei ethnicity also professed their allegiance to the Eastern Jin, but internally vied for independence. The Murong allowed Chinese refugees to settle in their domain and employed them as officials to serve in their civil administration. In 337, while still claiming to be a vassal of Jin, their chieftain, Murong Huang took the title of Prince and founded the Former Yan (337–370). He conquered the rival Duan and Yuwen tribes as well as forced the Goguryeo and Buyeo into submission, thus allowing his state to compete with the Later Zhao. Other regimes that existed around this time but are not listed among the Sixteen Kingdoms are the Tuoba-Xianbei of Dai and the Di-led Chouchi.
Former Qin and the brief unification of northern China (351–383)
In the course of the Later Zhao collapse, Ran Min formed his new state of Ran Wei (350–352). However, many Zhao generals refused to acknowledge him, and northern China fragmented into numerous regions controlled by warlords. The Former Yan, under Murong Jun, seized the moment to expand into the Central Plains. In 352, his brother, Murong Ke defeated and captured Ran Min at the Battle of Liantai. Murong Jun thereupon broke away from the Eastern Jin and proclaimed himself as emperor. The Yan continued their southward expansion, reaching all the way to the Huai river and establishing dominance over the northeast. After Murong Jun's death in 360, Murong Ke acted as regent for his child heir and maintained the Yan's military supremacy through his competent leadership. However, when he too died in 367, the issues of unbridled corruption among the aristorcracy and infighting within the imperial family became evident and rapidly worsened.
Among the states that emerged from the chaos was the Former Qin (351–394), established by the Later Zhao general, Fu Jiàn of Di ethnicity who captured and secured control over the Guanzhong region. In 357, his nephew Fu Jiān seized the throne from his despotic son in a coup. Despite his ethnicity, the younger Fu Jiān revered Confucianism and entrusted most of state affairs to his ethnic Chinese advisor, Wang Meng. The two enacted policies to help the Qin recover from the early wars and famines, while also effectively putting down rebellions and corruption throughout their domain. Within a decade, the Former Qin was transformed into a regional power in the northwest, competing with both the Former Yan and Eastern Jin.
In 370, Wang Meng led the Former Qin to invade the Former Yan, and though outnumbered, he was able to vanquish them in one fell swoop. Riding on his momentum, Fu Jiān unified northern China by subjugating the Chouchi, Former Liang and Dai while also capturing Sichuan from the Eastern Jin by 376. Fu Jiān had a tendency to spare and recruit his enemies, employing many of them in his government and military. With most of China under his rule, he sought to complete the unification by ending the Eastern Jin once and for all. Wang Meng opposed this move, and before his death in 375, he warned Fu Jiān that he first needed to address the growing friction between the various ethnic groups within his empire, especially in regards to the Xianbei and Qiang, but Fu Jiān did not heed his advice. In 383, he launched an invasion of southern China, where his vast army was defeated in a devastating rout at the Battle of Fei River by a significantly smaller Eastern Jin force.
Fragmentation after the Battle of Feishui (383–394)
After the Battle of Feishui, the power of the Former Qin quickly unraveled as numeroud regimes in the north began to break loose. In 384, Fu Jiān's general and a prince of the fallen Former Yan, Murong Chui rebelled in the Hebei and founded the Later Yan (384–409), intending to restore his family's dynasty. His relatives responded by forming the Western Yan (384–394; not listed among the Sixteen Kingdom) and laid siege on Fu Jiān at his capital in Chang'an. During the war, Fu Jiān's general of Qiang ethnicity, Yao Chang also rebelled and established the Later Qin (384–417). In 385, the Western Yan ousted Fu Jiān from Chang'an, and he was soon captured and executed by Yao Chang.
More states began to spring up in light of Fu Jiān's death. That same year, the Xianbei former vassal, Qifu Guoren founded the Western Qin (385–431) in eastern Gansu and the Chouchi was restored. In 386, the Di general, Lü Guang established the Later Liang (386–403) in western Gansu while another Xianbei leader, Tuoba Gui revived the Dai as the Northern Wei (386–535; not listed among the Sixteen Kingdoms). During the Later Yan's conquest of the northeast, the Dingling troops under Murong Chui mutinied, and in 388, they formed their state of Zhai Wei (388–392; not listed among the Sixteen Kingdoms).
Later Qin and the propagation of Buddhism (394–417)
For the next decade, Yao Chang fought against remnants of the Former Qin for supremacy over the Guanzhong. In 394, he was succeeded by his son, Yao Xing, who shortly after crushed the last remaining power of the Former Qin. He then ushered the Later Qin into a period of relative peace and prosperity. During his reign, the Later Qin received the nominal submissions of several neighbouring states such as the Later Liang and Western Qin and conquered the Henan region from the Eastern Jin, including the city of Luoyang.
Much like Fu Jiān, Yao Xing strongly adhered to Confucian principles. He turned Chang'an into an education hub by establishing schools and attracting many prospective scholars near and far. He was also a devout follower of Buddhism and actively spread the religion through widespread state support. In 401, after defeating the Later Liang into submission, he welcomed into his court the Kuchean monk, Kumārajīva and sponsored him to translate many Buddhist sutras, treatises and other texts from Sanskrit to Chinese. Mahayana Buddhism flourished under Yao Xing, with most of the Later Qin population following the teachings of the Buddha.
North of the Later Qin heartlands was the Ordos Plateau, which had long been home to various roaming tribes. These tribes, under constant threat by the Northern Wei in the east, submitted to the Qin and acted as a buffer on their northern frontier. As the raids on these tribes intensified, the Later Qin carried out a retaliatory campaign against the Northern Wei, but suffered a decisive defeat at the Battle of Chaibi in 402. From there, the empire stagnated, and as the Qin entered peace talks with the Wei, Helian Bobo of the Tiefu tribe rebelled in the Ordos and founded the Helian Xia (407–431), beginning a protracted war that drained the Qin's power and resources. Yao Xing soon lost control over his other vassals, and when he died in 416, he left his heir contending with his relatives over the throne. In 417, the Eastern Jin commander, Liu Yu took advantage of the tumultuous situation to conquer the Later Qin.
Gansu: The Four Liangs and Western Qin
In the Gansu, the Later Liang came to blows with the Western Qin. Though they gained the upper hand early on, the Liang was badly routed and suffered heavy losses during their invasion of Qin in 397. The defeat sparked upheaval in Later Liang, as soon after, the Xianbei chieftain, Tufa Wugu broke away and founded the Southern Liang (397–414), followed by the Chinese governor, Duan Ye, who established the Northern Liang (397–439) with the support of the Lushuihu chieftain, Juqu Mengxun. In 400, the Chinese general, Li Gao rebelled against the Northern Liang and formed the Western Liang (400–421). The next year, Juqu Mengxun deposed Duan Ye and took over the Northern Liang.
Between 400 and 401, the Later Qin carried out two western expeditions to Gansu, annexing the Western Qin and forcing the four Liangs into nominal submission. Unable to withstand anymore attacks, the Later Liang gave up their remaining territory to the Later Qin in 403. As the Later Qin weakened, the Southern Liang broke off relations in 407 while the Western Qin reestablished themselves in 409. The Southern Liang suffered heavy losses on the battlefield and fell to the Western Qin in 414. In 421, Juqu Mengxun pacified the Western Liang, leaving Northern Liang and Western Qin to compete for Gansu. Due to internal and external pressure, the Western Qin declined and were subjugated by the Helian Xia in 431, giving the Northern Liang sole control over Gansu for a brief period of time.
Northern Wei and the reunification of northern China (394–439)
Division of Later Yan
In the northeast, Murong Chui spent the majority of his reign waging war and quelling rebellions to recover his family's holdings in the northeast. He extinguished the Zhai Wei in 392 and conquered the Western Yan in 394. Yet, his former ally, the Northern Wei under Tuoba Gui remained a nuisance to his empire. In 395, he sent his sons to lead a punitive expedition against the Northern Wei, but Tuoba Gui dealt them a grave defeat at the Battle of Canhe Slope. In 396, Murong Chui personally led another campaign to Northern Wei in retribution, but died of illness along the way.
Not long after Murong Chui's heir took the throne, Tuoba Gui launched his own invasion of Later Yan. The Murong clan decided to concentrate their forces to their major cities, which allowed the Northern Wei to overrun the Central Plains. Though Tuoba Gui initially struggled to take their cities, he eventually won a decisive victory over the main Later Yan forces at the Battle of Baisi. The Murong family fell into infighting; the emperor decided to evacuate the Central Plains for his ancestral home in Liaodong, while an offshoot led by his uncle, Murong De founded the Southern Yan (398–410) and occupied the Shandong region. Following a coup, the Later Yan branch was later replaced by the Northern Yan (407–436), whose founder, Gao Yun was of Goguryeo descent, but his successor, Feng Ba, was a Han Chinese.
Reunification of Emperor Taiwu
With the Yan divided and a foothold on the Central Plains, the Northern Wei became the new regional power in the northeast. After Tuoba Gui's assassination in 409, his son, Tuoba Si, posthumously known as Emperor Mingyuan, succeeded him and prioritized in stabilizing the state over expanding. In the northwest, shortly after the Eastern Jin destroyed Later Qin, Helian Bobo took the opportunity to seize the Guanzhong region as Liu Yu returned to the south in 418.
In 423, Emperor Taiwu of Northern Wei ascended the throne with ambitions to unify northern China. Following the death of Helian Bobo in 425, he intensified his assault on the Helian Xia that by 428, he had captured both the Xia capital, Tongwancheng and their emperor. The emperor's brother, Helian Ding succeeded him and continued to resist. He made a last-ditch effort to save the empire by expanding westward, even conquering the weakened Western Qin in 431. However, as he attempted to invade the Northern Liang later that year, he was captured in a raid by the Tuyuhun nomads of modern Qinghai and sent to the Northern Wei as a prisoner.
With the defeat of their last major rival in northern China, reunification under the Northern Wei was inevitable. Emperor Taiwu turned his focus to the Northern Yan in 432, launching incessant attacks on their border. Eventually, in 436, the Northern Yan ruler was unable to resist a large-scale invasion by the Northern Wei and fled his territory for Goguryeo. The Northern Liang became the last of the Sixteen Kingdoms. Despite a marriage alliance between the two sides, Emperor Taiwu accused the Northern Liang of plotting rebellion and sent an expeditionary force into Gansu in 439. Placed under siege, the last ruler of Northern Liang soon surrendered. The Sixteen Kingdoms era came to an end, as the Northern Wei unification would last for nearly a century.
Relations with Eastern Jin
Diplomatic status
For the majority of the period, the Sixteen Kingdoms coincided with the Eastern Jin dynasty in southern China. Most people at the time viewed the Eastern Jin as a direct continuation of the Western Jin, since they were ruled by the same imperial Sima clan albeit distant members, and therefore had more right to rule than the other coinciding states. The Eastern Jin insisted on their status as supreme overlord and refused to treat any of their adversaries as equals. For instance, when the Later Zhao sent a diplomatic mission to the south to establish equal relations, they burnt the embassy's gifts and expelled the envoy. Some of the Sixteen Kingdoms such as Former Liang and Former Yan also agreed to nominally recognize the Eastern Jin as their suzerain for their source of legitimacy.
Eastern Jin efforts to retake the north
Yet, the Eastern Jin court was often divided on the subject of reclaiming lost territory. Many among the Jin elites, both the southern natives and northern migrants, enjoyed their new influence in the south and were content with maintaining a border along or above the Huai river in the north. On the other hand, reunification was still recognized as a moral obligation, and military generals who bring success from their campaigns were rewarded with titles and prestige. There were real concerns that powerful commanders would use the influence they gained from their campaigns as leverage against the court and the emperor. Hence, the court was often reluctant and passive in supporting expeditions against the Sixteen Kingdoms.
The first significant attempt to retake the north was carried out by Zu Ti, who led a voluntary expedition force in response to Emperor Min's call to arms in 313. Sima Rui, then still a prince, showed little interest in the expedition, and only provided Zu Ti very meager resources. Despite his limitations, Zu Ti managed to recapture a large swath of the Henan south of the Yellow River and repeatedly defeated the Later Zhao. However, with civil war looming back home, Sima Rui abruptly ended the expedition by stripping Zu Ti off his commanding role in 321, and his gains were swiftly reversed the following year.
The aftermath of Wang Dun and Su Jun's rebellions further discouraged the Jin court from launching expeditions as they required time to recuperate. Nonetheless, in 346–347, without prior authorization of the court, the general, Huan Wen invaded and ended the Cheng-Han state, bringing Sichuan back under Jin rule. Interest in recovering lost territory grew during the collapse of the Later Zhao, and Huan Wen was able to pressure the court into giving him command over the expeditionary forces. His first expedition against the Former Qin in 354 was unsuccessful, but his second expedition in 356 saw him recover the old capital of Luoyang. In 369, in his bid to claim the Jin throne, Huan Wen launched his third and final northern expedition against the Former Yan, but the campaign ended in failure as he suffered defeat at the Battle of Fangtou.
Not long after, Huan Wen died of illness and the Eastern Jin was faced with the rising power of Former Qin. Early on, the Jin lost Sichuan in 373 and then the major city of Xiangyang in 379. However, after their victory at the Battle of Feishui in 383, Jin forces led by Xie Xuan, Liu Laozhi others were able to recover them and push the Former Qin back all the way to the Yellow River. From there, the Eastern Jin reached a deadlock, and as internal strife and civil war plagued the Jin once more, the Later Qin seized the chance to annex the Henan region while the Southern Yan occupied Shandong in 399.
In 404, the Jin general, Liu Yu defeated the usurper, Huan Xuan and restored Emperor An to the throne. Liu Yu had ambitions to claim the throne for himself and built his legitimacy by launching northern expeditions. In 409–410, he led Jin forces to defeat and destroy the Southern Yan, thus recapturing the Shandong. In 416, taking advantage of the death of Yao Xing, he invaded Henan and captured Luoyang before turning towards the Guanzhong and seizing Chang'an. The last Later Qin ruler surrendered and was sent to Jiankang for execution. With the Later Qin destroyed, the Western Qin, Northern Liang and Western Liang nominally submitted to Eastern Jin authority. However, due to pressing matters back in the south, Liu Yu was forced to return, and in his absence, the Helian Xia invaded and conquered the Guanzhong. Despite the loss of the region, Liu Yu's expeditions were enough for him to usurp the throne and establish the Liu Song dynasty (420–479). The Liu Song and the rest of the Southern dynasties continued to wage war against their northern counterparts before the northern Sui dynasty (581–618) eventually unified China in 589.

Chronology
Governance
Through generational exposure and cooperation with the ethnic Han scholar gentry, the Sixteen Kingdoms heavily adopted the Chinese style of imperial governance and customs. Many of their rulers claimed the imperial titles of Emperor (帝; Dì) or King (王; Wáng), used era names and appointed their followers to official positions from the imperial Chinese system such as Grand Chancellor (丞相; Chéngxiàng) and Grand Tutor (太傅; Tàifù). Additionally, the imperial title of Heavenly King (天王; Tiānwáng) was introduced and widely used during this period as a way for rulers to acknowledge that they still lack the prerequisites of an Emperor while effectively acting as one.
