Chapter 12: The Liao, Jin, and Western Xia — The "Conquest Dynasties" (907–1234)

1. Introduction: The Significance of the Conquest Dynasties

The centuries between the fall of the Tang dynasty in 907 and the Mongol unification of China in 1279 were not simply the age of the Song. They were equally the age of the "conquest dynasties" — the Khitan Liao (辽朝, 907–1125), the Tangut Western Xia (西夏, 1038–1227), and the Jurchen Jin (金朝, 1115–1234) — non-Chinese states that controlled vast territories in northern and western China and that profoundly shaped the course of Chinese history. These dynasties were not peripheral to the Chinese story; they were central to it, challenging the Song militarily, diplomatically, and intellectually, and forcing Chinese thinkers to confront fundamental questions about the nature of Chinese civilization, the boundaries of "China," and the relationship between culture and political authority.

The concept of "conquest dynasties" (征服王朝, zhengfu wangchao) was articulated by the German-American historian Karl August Wittfogel in the 1940s to describe the distinctive political formations created when nomadic or semi-nomadic peoples conquered Chinese territory and established dynasties that combined elements of steppe and Chinese political traditions. The Liao, Jin, and Western Xia were all "dual administration" states that governed their diverse populations through parallel institutions — one set derived from the rulers' own steppe traditions for governing their nomadic subjects, and another derived from Chinese precedents for governing their sedentary Chinese subjects. This institutional innovation reflected the fundamental challenge facing all conquest dynasties: how to maintain the military effectiveness and cultural identity of the conquering people while governing a vastly larger Chinese population whose economic productivity, administrative expertise, and cultural prestige were indispensable to the functioning of the state.

The conquest dynasties have traditionally been marginalized in Chinese historiography, which has tended to view them as barbarian interlopers in the mainstream narrative of Chinese dynastic succession. Modern scholarship, however, has increasingly recognized their centrality to Chinese history. The institutional experiments of the Liao and Jin prepared the way for the Mongol Yuan and Manchu Qing dynasties, both of which adopted elements of the dual administration model. The cultural exchanges between Chinese and non-Chinese populations in the conquest dynasty territories contributed to the formation of the multi-ethnic Chinese civilization that exists today. And the very concept of "China" was shaped by the encounter between Chinese and non-Chinese political traditions during this period — an encounter that challenged the assumption that Chinese civilization was coterminous with the Chinese state and forced a rethinking of what it meant to be "Chinese."

2. The Khitan Liao Dynasty (907–1125)

The Khitan (契丹, Qidan) were a pastoral-nomadic people of the eastern Mongolian steppe whose homeland lay in the region of the Liao River valley and the Xar Moron River in what is today Inner Mongolia and Liaoning. The Khitan had been known to Chinese historians since the fourth century, but they emerged as a major political force only in the early tenth century under the leadership of Yelü Abaoji (耶律阿保机, 872–926), a chieftain of extraordinary political and military ability who united the various Khitan tribes and proclaimed himself emperor in 907 — the same year that the Tang dynasty fell.

Abaoji was a political innovator who recognized that the Khitan confederation needed institutional structures beyond the traditional tribal organization if it was to survive and expand. He created a Chinese-style bureaucracy alongside the traditional Khitan tribal leadership, recruited Chinese advisors (most notably the minister Han Yanhui 韩延徽, who had been captured during a Khitan raid and chose to serve his captors), and established permanent capital cities — the Supreme Capital (上京, Shangjing, near modern Baarin Left Banner in Inner Mongolia) and subsequently four additional capitals — that served as administrative centers for the growing empire. Abaoji also commissioned the creation of two Khitan scripts — a "large script" modeled on Chinese characters and a "small script" based on an alphabetic principle — to provide the Khitan with their own written language, a powerful symbol of independent identity.

Under Abaoji's successors, the Khitan Liao expanded dramatically. The most consequential expansion came in 936–938, when the Liao allied with the Chinese general Shi Jingtang (石敬瑭) in his bid to establish the Later Jin dynasty (one of the Five Dynasties). In return for Liao military support, Shi Jingtang ceded the "Sixteen Prefectures" (燕云十六州, Yanyun shiliu zhou) — a strategic belt of territory south of the Great Wall that included modern Beijing and Datong — to the Liao. This cession gave the Khitan control of the key mountain passes defending the North China Plain, fundamentally altering the strategic balance of power in East Asia. The Song dynasty's inability to recover the Sixteen Prefectures was the single most important factor in its chronic military vulnerability.

By the mid-tenth century, the Liao controlled an empire that stretched from the Mongolian steppe to the agricultural heartland of northern China — a vast territory inhabited by Khitan nomads, Chinese farmers, Bohai urbanites, and various other peoples. Governing this diverse empire required innovative institutional solutions, and the Liao response was the most sophisticated version of what historians have called "dual administration" (南北面官制, nanbei mianguan zhi, literally "northern and southern facing officials system"). Under this system, the Northern Administration (北面官, beimian guan) governed the Khitan and other nomadic peoples according to tribal custom, while the Southern Administration (南面官, nanmian guan) governed the Chinese population according to Chinese-style bureaucratic institutions, including a system of prefectures and counties, Chinese legal codes, and elements of the civil service examination system.

The dual administration was not simply a pragmatic division of labor; it reflected a deliberate political strategy of maintaining the distinct identities and institutions of both the ruling Khitan elite and their Chinese subjects. The Liao emperors presented themselves differently to different audiences: to the Khitan, they were khans and tribal leaders who upheld the traditions of the steppe; to their Chinese subjects, they were emperors in the Chinese tradition who performed Chinese rituals, patronized Confucian scholarship, and governed through a Chinese-style bureaucracy. This strategic duality — which later scholars have called "bifurcated sovereignty" — was a Liao innovation that would be adopted and adapted by subsequent conquest dynasties, most notably the Mongol Yuan and the Manchu Qing.

The relationship between the Liao and the Song was defined by the Treaty of Chanyuan (澶渊之盟, Chanyuan zhi meng) of 1005, one of the most important diplomatic agreements in Chinese history. After a Liao invasion that penetrated deep into Song territory, the two sides negotiated a peace settlement in which the Song agreed to pay annual "tribute" (though diplomatically disguised as "gifts") of 200,000 bolts of silk and 100,000 ounces of silver to the Liao. In return, the Liao recognized the Song emperor as an "elder brother" and agreed to maintain peaceful relations. The treaty held for over a century, creating an extended period of peace and cross-border trade that benefited both sides. The Chanyuan settlement established a model for interstate relations in the multi-state system of the period — a model based on negotiated coexistence rather than Chinese hegemony, and on the recognition that the Song was one state among several rather than the universal empire of Chinese tradition.

The Liao dynasty also made significant cultural contributions. Liao Buddhism was extraordinarily vibrant, producing magnificent wooden temples (the oldest surviving wooden buildings in China, such as the Guanyin Pavilion at Dule Temple in Jixian, date from the Liao period), Buddhist sculptures of remarkable artistic quality, and extensive libraries of Buddhist texts. The Liao also preserved elements of Tang culture that had been lost in the south, and the cultural exchange between the Liao and the Song was more extensive than traditional historiography — with its emphasis on military confrontation — has generally acknowledged.

3. The Tangut Western Xia (1038–1227)

The Western Xia (西夏, Xixia), also known as the Tangut Empire (or by its Tangut name, Mi-nyak), was a kingdom established by the Tangut people in the arid regions of what is today Ningxia, Gansu, and parts of Inner Mongolia and Qinghai. Though smaller and less well-known than the Liao and Jin, the Western Xia was a significant political and cultural power that controlled the crucial Hexi Corridor — the narrow passage between the Tibetan Plateau and the Mongolian steppe that formed the eastern gateway of the Silk Road — for nearly two centuries.

The Tangut (党项, Dangxiang) were a Tibeto-Burman-speaking people related to the Qiang, who had migrated from the Tibetan frontier to the Ordos region during the Tang dynasty. During the Five Dynasties period, the Tangut chieftains accumulated political and military power in the northwestern borderlands. In 1038, the Tangut leader Li Yuanhao (李元昊, 1003–1048) proclaimed himself emperor of the Great Xia (大夏), establishing a new dynasty that would endure until the Mongol conquest in 1227.

Li Yuanhao was a remarkable statesman who systematically built the institutional framework of the Western Xia state. Like the Khitan before him, he sought to balance Chinese-style administration with the preservation of Tangut cultural identity. He commissioned the creation of a distinctive Tangut script — an elaborate writing system of several thousand characters that was structurally inspired by Chinese characters but entirely distinct from them. The Tangut script, which remained in use throughout the life of the dynasty and for some time afterward, was a powerful symbol of Tangut identity and independence. Modern scholars have deciphered the script, revealing a rich body of Tangut literature that includes translations of Chinese classics, Buddhist texts, legal codes, and original Tangut compositions.

The Western Xia's strategic position on the Silk Road made it a crucial intermediary in trans-Asian trade, and the Tangut economy benefited enormously from commerce in horses, salt, camels, furs, and luxury goods. The Xia capital of Xingqing (兴庆, modern Yinchuan) was a prosperous city that combined Chinese urban planning with Tangut, Tibetan, and Central Asian cultural elements.

Buddhism was central to Western Xia culture and identity. The Tangut court patronized Buddhist institutions on a lavish scale, and Western Xia Buddhists produced a remarkable body of religious art and literature. The cave temples of the Western Xia — including sites at Yulin (榆林窟), Wuwei, and other locations along the Hexi Corridor — contain Buddhist paintings and sculptures of distinctive artistic character. The most extraordinary Western Xia Buddhist achievement was the printing of the entire Buddhist canon in the Tangut language — a monumental publishing project that testifies to both the religious devotion and the technological sophistication of the Tangut state.

The Western Xia's relations with the Song were marked by intermittent warfare and uneasy coexistence. The early decades of the Xia were dominated by military conflict with the Song, including devastating Tangut raids on Song frontier districts and costly Song counteroffensives that generally failed to achieve their objectives. By the mid-eleventh century, both sides recognized the futility of continued warfare, and a peace settlement established a pattern of diplomatic relations similar to the Song-Liao relationship — the Song provided annual payments to the Xia, and the Xia nominally acknowledged Song suzerainty while maintaining its independence in practice.

The Western Xia was destroyed by the Mongols in a campaign of exceptional brutality. Chinggis Khan invaded the Xia multiple times between 1205 and 1227, and the final Mongol campaign in 1226–1227 resulted in the complete destruction of the Tangut state. Chinggis Khan himself died during the campaign (according to most accounts, from injuries sustained in a fall from his horse during a hunt), and the Mongols — possibly in revenge for the Tangut resistance — systematically destroyed the Xia capital and massacred much of the Tangut population. The Western Xia vanished so completely that for centuries it was known primarily through brief references in Chinese and Mongol sources. The rediscovery of Tangut texts and artifacts in the twentieth century — most dramatically by the Russian explorer Pyotr Kozlov, who discovered the ruined city of Khara-Khoto in 1908 and recovered thousands of Tangut manuscripts — has enabled modern scholars to reconstruct the history and culture of this remarkable civilization.

4. The Jurchen Jin Dynasty (1115–1234)

The Jurchen (女真, Nüzhen) were a semi-nomadic, semi-agricultural people of Tungusic origin who inhabited the forests and river valleys of Manchuria — the region northeast of the Great Wall that encompasses modern Heilongjiang, Jilin, and Liaoning provinces. Subjects of the Khitan Liao dynasty, the Jurchen rose in rebellion in 1114 under the leadership of the chieftain Wanyan Aguda (完颜阿骨打, 1068–1123), who proclaimed the establishment of the Jin dynasty (金朝, literally "Golden dynasty") in 1115 and embarked on a war of conquest that would destroy the Liao, shatter the Song, and establish Jurchen dominion over all of northern China.

The Jurchen conquests were achieved with remarkable speed. The Liao, weakened by internal divisions and overextension, collapsed before the Jurchen onslaught: the Liao Supreme Capital fell in 1120, and the last Liao emperor was captured in 1125, ending two centuries of Khitan rule. The Jin then turned against the Song — with which they had briefly been allied against the Liao — and in the devastating Jingkang Incident of 1126–1127, Jurchen armies captured the Song capital of Kaifeng and carried off the Song emperors, effectively destroying the Northern Song.

By the 1130s, the Jin controlled all of China north of the Huai River — the Yellow River valley, the Central Plain, the old capitals of Luoyang and Kaifeng, and the enormous agricultural wealth and dense population of the north. The Jin was now the largest and most populous state in East Asia, governing perhaps 50 million people, the vast majority of whom were Chinese. This demographic reality posed the fundamental challenge of Jurchen rule: how could a small minority of perhaps one to two million Jurchen govern a Chinese population that outnumbered them more than twenty to one?

The Jin response combined elements of the Liao dual administration model with distinctive Jurchen innovations. The early Jin emperors maintained the traditional Jurchen military organization — the meng'an mouke (猛安谋克) system, in which Jurchen (and later other) households were organized into military-administrative units of thousands (猛安, meng'an) and hundreds (谋克, mouke) — as the basis of Jurchen power and identity. Jurchen soldiers and their families were settled on confiscated Chinese land in northern China, creating a system of military colonies that provided the Jin with a ready reserve of cavalry warriors while maintaining the separate social identity of the Jurchen elite.

At the same time, the Jin adopted Chinese-style civil administration for governing the Chinese population, including a full complement of central government agencies, provincial and local administration, law codes based on Chinese precedents, and — crucially — the civil service examination system. The Jin examinations, which were conducted in both Chinese and Jurchen, opened a path to office for Chinese scholar-officials and helped to legitimate Jurchen rule in the eyes of the Chinese population. The Jin court also patronized Confucian scholarship, commissioned the compilation of official histories, and adopted many elements of Chinese court ritual and ceremony.

The most significant development of the Jin period was the process of "Sinicization" (汉化, hanhua) — the gradual adoption of Chinese language, customs, and cultural practices by the Jurchen elite. This process was both natural and deeply controversial. The sheer weight of Chinese civilization — its literary tradition, its philosophical sophistication, its material culture — exerted an irresistible pull on the Jurchen ruling class, particularly those who lived in the Chinese heartland rather than on the Manchurian frontier. Jurchen nobles adopted Chinese clothing, learned to speak and write Chinese, studied the Confucian classics, wrote poetry in Chinese, and intermarried with Chinese families.

The Jin court was acutely aware of the dangers of excessive Sinicization and made repeated efforts to preserve Jurchen identity. Emperor Shizong (金世宗, r. 1161–1189), often regarded as the greatest Jin ruler, promoted the use of the Jurchen language, encouraged traditional Jurchen customs such as hunting and archery, and attempted to revitalize the Jurchen script that had been created under Aguda. But the tide of Sinicization proved unstoppable: by the late twelfth century, many Jurchen in northern China had effectively become Chinese in all but name, and the Jurchen language was in decline even at court. The tension between Sinicization and cultural preservation — between the practical benefits of adopting Chinese culture and the political necessity of maintaining a distinct ruling-class identity — would recur with even greater intensity under the Mongol Yuan and Manchu Qing dynasties.

The Jin dynasty experienced a cultural flowering in its middle period. Jin poetry, written in Chinese, produced several important poets, and the Jin capital of Zhongdu (中都, modern Beijing) — built on the site of the old Liao Southern Capital — became a major cultural center. The Jin was also the birthplace of important developments in Chinese religion, including the founding of the Quanzhen (全真) school of Daoism by Wang Chongyang (王重阳, 1113–1170), which would become one of the dominant Daoist movements of the subsequent centuries.

5. Dual Administration and the Innovation of Governance

The most important institutional legacy of the conquest dynasties was the "dual administration" model — the system of governing diverse populations through parallel institutions adapted to the distinct needs and traditions of different groups. This model, first developed by the Khitan Liao and refined by the Jurchen Jin and the Tangut Western Xia, represented a genuinely original contribution to the art of governance — one that departed fundamentally from the Chinese imperial model of universal bureaucratic administration and from the purely tribal organization of the steppe.

The logic of dual administration was straightforward: the conquest dynasties ruled populations with fundamentally different economic bases, social structures, and cultural traditions. The nomadic and semi-nomadic peoples of the steppe — Khitan, Jurchen, or Tangut — organized their societies around kinship, tribal solidarity, and military prowess. Their economies depended on pastoralism, hunting, and mounted warfare. Their political traditions emphasized personal loyalty to the khan, collective decision-making by tribal elders, and the distribution of booty and honors among military followers. Chinese society, by contrast, was organized around settled agriculture, Confucian ethics, bureaucratic administration, and a literary culture that took centuries of sustained study to master. Any attempt to govern both populations through a single set of institutions would inevitably fail — either by imposing inappropriate Chinese institutions on nomads or by applying steppe customs to a sedentary Chinese population.

The dual administration resolved this dilemma by maintaining two parallel systems of governance. Under the Liao, the "Northern Administration" handled Khitan and other nomadic affairs through tribal leaders, military commanders, and customary law, while the "Southern Administration" governed the Chinese population through prefects, magistrates, Chinese law codes, and the examination system. The two systems operated under a single sovereign — the Liao emperor, who served simultaneously as tribal khan and Chinese-style emperor — but were otherwise largely independent of each other.

The Jin refined this model, gradually integrating the two administrative systems as the process of Sinicization blurred the boundaries between Jurchen and Chinese society. The Jin meng'an mouke system, which originally served purely military and tribal functions, was progressively adapted to serve as a system of territorial administration, and Jurchen and Chinese institutions increasingly overlapped and merged. This process of institutional convergence anticipated the more thoroughgoing integration that would characterize the Mongol Yuan and Manchu Qing dynasties.

The dual administration model had profound implications for the Chinese political tradition. It demonstrated that the Chinese empire was not the only viable form of political organization in East Asia and that non-Chinese peoples could create sophisticated, durable states that combined Chinese and non-Chinese elements in creative ways. It also challenged the assumption — central to Confucian political thought — that there could be only one legitimate sovereign under heaven and that all other rulers were, by definition, barbarian usurpers. The conquest dynasties forced Chinese thinkers to grapple with the reality of a multi-state system in which Chinese civilization was not politically supreme, and this intellectual challenge contributed to the development of more nuanced theories of sovereignty, legitimacy, and cultural identity.

6. Sinicization Versus Preservation of Steppe Culture

The tension between Sinicization and the preservation of the conquerors' own cultural identity was the defining dynamic of the conquest dynasties — a dynamic that would recur with each successive wave of non-Chinese rule over Chinese territory. Every conquest dynasty faced the same fundamental dilemma: Chinese civilization offered an irresistible package of administrative sophistication, literary culture, economic productivity, and philosophical depth that no conquering people could afford to ignore. Yet the adoption of Chinese culture threatened to dissolve the very identity that gave the conquering elite its cohesion, its military effectiveness, and its claim to rule.

The Khitan Liao approached this dilemma with characteristic pragmatism. The Liao emperors adopted Chinese-style governance for their Chinese subjects while maintaining Khitan tribal institutions, language, and customs for the Khitan population. The annual cycle of Liao imperial life reflected this duality: the emperor spent part of the year in the Chinese-style southern capital, performing Chinese rituals and governing through Chinese-style bureaucratic institutions, and part of the year in the northern steppe, hunting, leading tribal assemblies, and reinforcing his identity as a steppe ruler. The Khitan elite maintained their language, their distinctive hairstyle (partially shaved heads), their nomadic hunting culture, and their shamanic religious traditions alongside their adoption of Chinese Buddhism and administrative practices. This "selective Sinicization" — adopting Chinese institutions where they were useful while maintaining distinct Khitan traditions where they were valued — proved remarkably successful, sustaining Khitan identity and political cohesion for over two centuries.

The Jurchen Jin experienced Sinicization more intensively and more conflictedly. The early Jin emperors — warriors who had conquered their empire from horseback — maintained a robust Jurchen identity characterized by martial values, the Jurchen language, and traditional customs. But as the decades passed and the Jurchen elite settled in Chinese cities, adopted Chinese lifestyles, and intermarried with Chinese families, the boundaries between Jurchen and Chinese blurred. The great crisis came in the late twelfth century, when Emperor Shizong, alarmed by the rapid erosion of Jurchen identity, launched a sustained campaign of cultural revival. He commanded Jurchen nobles to speak the Jurchen language, practice archery and horsemanship, and maintain traditional Jurchen customs. He promoted the Jurchen script, established schools to teach Jurchen language and literature, and attempted to create a distinctively Jurchen literary and intellectual culture.

Shizong's cultural revival had limited success. The economic and cultural attractions of Chinese civilization were simply too powerful to resist, and most Jurchen in the Chinese heartland continued to assimilate. The Jurchen who maintained the strongest cultural identity were those who remained in Manchuria, far from the seductive influence of Chinese urban culture. This geographical pattern — cultural assimilation in the Chinese heartland versus cultural preservation on the frontier — would recur in the Mongol and Manchu periods.

The Western Xia found a somewhat different solution to the Sinicization dilemma. The Tangut adopted Chinese-style governance, Buddhist culture, and many elements of Chinese material culture, but they maintained their own language and script, their own legal traditions, and a distinctive cultural identity that drew on Tibetan, Central Asian, and Chinese elements. The relative isolation of the Western Xia from the Chinese heartland — compared to the Liao and Jin, which controlled large Chinese populations — made it easier for the Tangut to maintain their cultural distinctiveness.

The experience of the conquest dynasties demonstrated that the relationship between Chinese and non-Chinese cultures was not a simple process of one-way assimilation. The conquest dynasties were not merely passive recipients of Chinese cultural influence; they were creative actors who selected, adapted, and transformed Chinese institutions and practices to serve their own needs, while simultaneously contributing their own cultural traditions to the evolving mosaic of Chinese civilization. The "Sinicization" of the conquest dynasties was always a two-way process — the conquering peoples changed Chinese civilization even as Chinese civilization changed them.

7. The Frontier as a Zone of Cultural Exchange

The frontiers between the Song and the conquest dynasties were not simply lines of military confrontation; they were zones of intensive cultural, economic, and human exchange that profoundly shaped all the societies involved. The conventional image of the frontier as a barrier between "Chinese" and "barbarian" civilizations is misleading; in reality, the frontier was a permeable membrane through which people, goods, ideas, and cultural practices flowed in both directions.

Trade was the most visible form of frontier exchange. Despite intermittent warfare, commercial relations between the Song and the conquest dynasties were extensive and mutually beneficial. The Song exported tea, silk, porcelain, books, and other manufactured goods to the Liao, Jin, and Western Xia, while receiving horses, furs, medicinal herbs, and pastoral products in return. Formal "border markets" (榷场, quechang) were established at designated points along the frontier, where merchants from both sides could conduct business under official supervision. These markets generated substantial revenue for both governments and created networks of commercial interdependence that reinforced diplomatic relations and contributed to periods of peace.

Informal trade — smuggling — was equally important. Despite repeated government prohibitions on the export of strategically sensitive goods (particularly iron, weapons, and books containing military or technical information), the frontier was porous, and enterprising merchants found ways to evade official controls. The demand for Chinese tea was particularly insatiable: the nomadic peoples of the north, whose diet was heavy in meat and dairy products, found tea to be a dietary necessity, and the "tea-horse trade" (茶马贸易, chama maoyi) — the exchange of Chinese tea for steppe horses — became one of the most important commercial relationships in East Asian history.

Human migration across the frontier was also extensive. Chinese farmers, merchants, artisans, and scholars migrated northward into Liao and Jin territory, attracted by economic opportunities and sometimes pushed by overpopulation and social pressures in the south. Conversely, Khitan, Jurchen, and other non-Chinese peoples migrated southward, particularly during periods of political upheaval. The result was a frontier population of extraordinary ethnic and cultural diversity, in which Chinese and non-Chinese peoples lived side by side, intermarried, adopted each other's languages and customs, and created hybrid cultural forms that defied easy categorization.

Religion was another important medium of cross-frontier exchange. Buddhism, which had deep roots in both Chinese and steppe cultures, served as a common cultural language that transcended ethnic and political boundaries. Buddhist monks, texts, and artistic traditions circulated freely across the frontiers, creating a shared religious culture that connected the Song, Liao, Jin, and Western Xia. The Liao and Western Xia, in particular, were enthusiastic patrons of Buddhism, and some of the most magnificent Buddhist art and architecture of the period was produced in conquest dynasty territories.

The frontier was also a zone of intellectual and literary exchange. Chinese books — including the Confucian classics, histories, literary collections, and technical manuals — were avidly sought by the conquest dynasty courts, which used them to train their bureaucrats, educate their elites, and enrich their cultures. The Liao, Jin, and Western Xia all established schools and academies where Chinese learning was taught, and many non-Chinese scholars achieved genuine distinction in Chinese literary and intellectual culture. Conversely, Chinese scholars who lived in or visited the conquest dynasty territories gained knowledge of steppe languages, customs, and political traditions that broadened their understanding of the wider world.

The cumulative effect of this frontier exchange was the gradual integration of the diverse peoples of East Asia into a shared cultural sphere — a process that laid the foundations for the multi-ethnic empires of the Yuan and Qing and for the multi-ethnic nation that China has become today. The conquest dynasties were not obstacles to Chinese civilization; they were participants in its ongoing creation.

8. Impact on Chinese History and Identity

The conquest dynasties had a profound and lasting impact on Chinese history and on the Chinese understanding of their own civilization. Their most immediate impact was military and political: the Liao, Jin, and Western Xia collectively controlled northern China for over three centuries, denying the Song access to the traditional heartland of Chinese civilization and forcing the Song to develop the southern economy and maritime trade as alternatives to the lost northern territories. The loss of the north was a traumatic experience that shaped Song political culture, stimulated institutional innovation, and contributed to the distinctive character of Song civilization.

The conquest dynasties also challenged the fundamental assumptions of the Chinese political tradition. The Confucian theory of universal empire — the idea that there could be only one legitimate sovereign under heaven, that the Chinese emperor was the Son of Heaven ruling all civilized peoples — was difficult to sustain when the "Son of Heaven" controlled only half of "China" while the other half was governed by "barbarian" rulers who claimed equal or superior status. The Chanyuan Treaty of 1005, in which the Song emperor acknowledged the Liao emperor as an "elder brother," was a diplomatic humiliation that contradicted the entire ideology of Chinese universal sovereignty. The Shaoxing Treaty of 1141, in which the Song accepted the role of vassal to the Jurchen Jin, was even more devastating to Chinese self-image.

These diplomatic humiliations provoked intense intellectual debate about the nature of Chinese civilization and its relationship to political power. Some Song thinkers, most notably the Neo-Confucian philosopher Zhu Xi, responded by sharpening the distinction between "Chinese" (华, hua) and "barbarian" (夷, yi) and insisting that cultural and moral cultivation — not military power or political control — was the true measure of civilization. In this view, the Song might be militarily weak, but it was culturally and morally superior to the conquest dynasties, and this cultural superiority was what truly mattered. Other thinkers took a more pragmatic view, acknowledging that the conquest dynasties had legitimate claims to sovereignty and that the multi-state system of the period was a reality that had to be accepted and managed rather than denied.

The conquest dynasties also contributed directly to the formation of Chinese identity by demonstrating that "China" was not an ethnically homogeneous civilization but a culturally defined one — a civilization that could absorb and transform diverse peoples and traditions while maintaining its essential character. The Khitan, Jurchen, and Tangut all adopted significant elements of Chinese culture, and their descendants were eventually absorbed into the Chinese population. This process of absorption and assimilation was not a one-way street: the conquest dynasties enriched Chinese civilization with their own traditions, institutions, and cultural practices, contributing to the multi-ethnic, multicultural character of Chinese civilization that persists to the present day.

The institutional legacies of the conquest dynasties were equally significant. The dual administration model, the practice of governing diverse populations through parallel institutions, and the techniques of maintaining a ruling-class identity while governing a culturally alien majority — all of these were conquest dynasty innovations that would be adopted and refined by the Mongol Yuan and Manchu Qing dynasties. The Qing dynasty, in particular, drew extensively on the precedents set by the Liao and Jin in developing its own system of governing a multi-ethnic empire — a system that would, in turn, shape the multi-ethnic structure of the modern Chinese state.

Perhaps the most profound legacy of the conquest dynasties was the expansion of the concept of "China" itself. Before the conquest dynasty period, "China" had been largely identified with the agricultural civilization of the Yellow River valley and the Yangtze basin. The conquest dynasties, by incorporating the steppe, the forests of Manchuria, and the deserts of the northwest into the political orbit of Chinese civilization, expanded the geographical and cultural boundaries of "China" far beyond its traditional limits. This expanded definition of "China" — as a multi-ethnic, multi-cultural civilization rather than a single ethnic homeland — was reinforced by the Mongol Yuan and the Manchu Qing, and it remains the foundation of the Chinese state's claim to sovereignty over its vast and diverse territory today.
