中国五千年：辽金西夏：与宋并存的多民族政权
辽、金、西夏是与宋朝并存的多民族政权，它们的兴起改变了中国北方与西北的政治格局。辽朝由契丹人建立，耶律阿保机于公元九一六年称帝建国，国号契丹，后改称辽。辽通过南北面官制分别管理契丹与汉人事务，在北方草原与农耕地区之间保持了较长时间的稳定。公元一〇〇五年，宋辽订立澶渊之盟，双方约定以岁币换取边境和平，此后宋辽之间维持了约百年的相对和平，贸易与文化交流也有所发展。
西夏由党项人建立，李元昊于公元一〇三八年称帝，国号大夏，定都兴庆府。西夏创制了西夏文字，发展农业、畜牧与河西走廊贸易，在宋、辽、金之间周旋，维持了约近二百年的割据。
金朝由女真人建立，完颜阿骨打于公元一一一五年称帝，国号金。金先与北宋联手灭辽，又于一一二七年灭北宋，占据中原，迁都中都，并推行汉化改革，吸收中原制度与文化。南宋与金后来达成绍兴和议，形成南北对峙。
蒙古兴起后，西夏、金先后灭亡，西夏亡于一二二七年，金亡于一二三四年。在文化与社会上，辽朝佛教兴盛，山西应县木塔等建筑留存至今，契丹文字的创制反映了本民族的文化自觉；金朝在占领中原后设立科举，吸收汉人官僚，女真文字与汉字并用，逐渐从游牧习俗向农耕社会的制度靠拢；西夏则在佛教、法律与教育上自成体系，黑水城等地出土的西夏文献，成为今天研究西夏历史的重要资料。
经济上，三者都重视农业开垦与商路经营，辽的南京析津府、金的中都、西夏的兴庆府都是当时的区域中心。宋与辽、金、西夏之间虽有战争与岁币往来，但边境榷场贸易长期存在，茶叶、马匹、丝绸、瓷器互通有无，民间交往并未完全中断。
辽、金、西夏的存在表明，中国历史并非单一民族的线性叙事，而是多民族政权并存、交往、融合的过程，它们的制度、文字与边疆经营，对后世统一多民族国家的形成有重要影响。

Five Thousand Years of China: Liao, Jin and Western Xia: Multi-Ethnic Regimes Alongside the Song
The Liao, Jin and Western Xia were multi-ethnic regimes that coexisted with the Song, and their rise changed the political pattern of China's north and northwest. The Liao was founded by the Khitan: Yelü Abaoji took the imperial throne and founded the state in 916, with the dynastic name Qidan (Khitan), later changed to Liao. Through its dual system of northern and southern administrations, the Liao governed Khitan and Han affairs separately and kept relative stability for a long period between the northern steppe and the farming regions.
In 1005, Song and Liao concluded the Treaty of Chanyuan, agreeing to exchange annual payments for border peace; thereafter Song and Liao maintained relative peace for about a century, and trade and cultural exchange developed as well. The Western Xia was founded by the Tanguts: Li Yuanhao took the imperial throne in 1038, with the state name Great Xia and his capital at Xingqing.
Western Xia created the Tangut script, developed agriculture, animal husbandry and trade along the Hexi Corridor, and manoeuvred among Song, Liao and Jin, maintaining its separatist rule for nearly two hundred years. The Jin was founded by the Jurchen: Wanyan Aguda took the imperial throne in 1115, with the state name Jin.
The Jin first joined with the Northern Song to destroy the Liao, then in 1127 destroyed the Northern Song itself, occupying the Central Plains, moving its capital to Zhongdu, and carrying out sinicizing reforms that absorbed Central Plains institutions and culture. The Southern Song and Jin later reached the Shaoxing Peace, forming a north-south standoff.
After the Mongols rose, Western Xia and Jin fell in turn — Western Xia in 1227, Jin in 1234. In culture and society, Buddhism flourished under the Liao, leaving buildings such as the Yingxian Wooden Pagoda in Shanxi, and the creation of the Khitan script reflects the people's cultural self-awareness;
after occupying the Central Plains, the Jin instituted examinations and absorbed Han officials, using the Jurchen and Chinese scripts side by side and gradually moving from nomadic customs toward the institutions of a farming society; Western Xia formed its own systems in Buddhism, law and education, and the Tangut documents excavated at places such as Khara-Khoto are important materials for studying Western Xia history today.
Economically, all three valued land reclamation and trade routes; the Liao's Nanjing (Xijin), the Jin's Zhongdu and Western Xia's Xingqing were all regional centres of their time. Though there were wars and annual payments between Song and the Liao, Jin and Western Xia, border market trade existed for a long time, with tea, horses, silk and porcelain exchanged, and popular intercourse never ceased entirely.
The existence of the Liao, Jin and Western Xia shows that Chinese history is not the linear narrative of a single people, but a process in which multiple peoples' regimes coexisted, interacted and fused; their institutions, scripts and management of the frontiers influenced the later formation of a unified multi-ethnic state.
