Five Dynasties and Ten Kingdoms period in the context of "Western Xia"

The Tang dynasty (/tɑːŋ/, [tʰǎŋ]; Chinese: 唐朝), or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilisation, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivalled that of the Han dynasty.

The Li family founded the dynasty after taking advantage of a period of Sui decline and precipitating their final collapse, in turn inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The An Lushan rebellion (755–763) led to devastation and the decline of central authority during the latter half of the dynasty.

The Song dynasty (/sʊŋ/ SUUNG) was a unifying imperial dynasty of China that ruled from 960 to 1279. The dynasty was founded by Emperor Taizu of Song, who usurped the throne of the Later Zhou dynasty and went on to conquer the rest of the Ten Kingdoms, ending the Five Dynasties and Ten Kingdoms period. The Song often came into conflict with the contemporaneous Liao, Western Xia and Jin dynasties in northern China. After retreating to southern China following attacks by the Jin dynasty, the Song was eventually conquered by the Mongol-led Yuan dynasty.

The dynasty's history is divided into two periods: during the Northern Song (北宋; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now East China. The Southern Song (南宋; 1127–1279) comprise the period following the loss of control over the northern half of Song territory to the Jurchen-led Jin dynasty in the Jin–Song wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng in Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.

Zhou, known as the Later Zhou (/dʒoʊ/; simplified Chinese: 后周; traditional Chinese: 後周; pinyin: Hòu Zhōu) in historiography, was a short-lived Chinese imperial dynasty and the last of the Five Dynasties that controlled most of northern China during the Five Dynasties and Ten Kingdoms period. Founded by Guo Wei (Emperor Taizu), it was preceded by the Later Han dynasty and succeeded by the Northern Song dynasty.

The Song dynasty (Chinese: 宋朝; pinyin: Sòng cháo; 960–1279) of China was an imperial dynasty that ruled most of China proper and southern China from the middle of the 10th century into the last quarter of the 13th century. The dynasty was established by Emperor Taizu of Song with his usurpation of the throne of Later Zhou, ending the Five Dynasties and Ten Kingdoms period.

The Song is considered a high point of classical Chinese innovation in science and technology, an era that featured prominent intellectual figures such as Shen Kuo and Su Song and the revolutionary use of gunpowder weapons. However, it was also a period of political and military turmoil, with opposing and often aggressive political factions formed at court that impeded political, social, and economic progress. The frontier management policies of the Chancellor Wang Anshi exacerbated hostile conditions along the Chinese-Vietnamese border. This sparked a border war with Vietnam's Lý dynasty, which was fought to a mutual draw and concluded with a peace treaty in 1082. To the northwest the Song Empire frequently fought battles with the Tangut-led Western Xia dynasty, as well as the Khitan-led Liao dynasty to the north.

The Han-Zhao (simplified Chinese: 汉赵; traditional Chinese: 漢趙; pinyin: Hàn Zhào; 304–329 AD), or Former Zhao (simplified Chinese: 前赵; traditional Chinese: 前趙; pinyin: Qián Zhào), was a dynastic state of China ruled by the Liu (Luandi) clan of Chuge-Xiongnu ethnicity during the Sixteen Kingdoms period of Chinese history. In Chinese historiography, it was given two conditional state titles, the Northern Han (北漢; Běi Hàn) for the state proclaimed in 304 by Liu Yuan, and the Former Zhao (前趙; Qián Zhào) for the state proclaimed in 319 by Liu Yao. The reference to them as separate states can be misleading, given that when Liu Yao changed the name of the state from "Han" to "Zhao" in 319, he treated the state as having been continuous from when Liu Yuan founded it in 304; instead, he de-established his imperial lineage from the Han dynasty and claimed ancestry directly from Modu Chanyu.

The reason it is also referred to as "Former Zhao" in historiography is to distinguish it from the Later Zhao founded by Shi Le in 319, which was also known officially as "Zhao". Since both the Former Zhao and Northern Han were ruled by the same family, Chinese scholars often conditionally combined them into a single Han-Zhao regime. Numerous Western texts refer to the two states separately; others referred to the Han state as the "Northern Han" (not to be confused with Northern Han of the Five Dynasties and Ten Kingdoms period).

Wu (Chinese: 吳; pinyin: Wú; Middle Chinese *ŋuo < Eastern Han Chinese: *ŋuɑ), known in historiography as Eastern Wu or Sun Wu, was a dynastic state of China and one of the three major states that competed for supremacy over China during the Three Kingdoms period. It previously existed from 220 to 222 as a vassal kingdom nominally under its rival state Cao Wei but declared complete independence in November 222. It was elevated to an empire in May 229 after its founding ruler Sun Quan (Emperor Da) declared himself emperor.

The name Wu was derived from the place it was based in—the Jiangnan (Yangtze River Delta) region, which was also historically known as Wu. It was called Dong Wu ("Eastern Wu") or Sun Wu by historians to distinguish it from other Chinese historical states with similar names in that region, such as the Wu state of the Spring and Autumn period and the Wuyue kingdom of the Five Dynasties and Ten Kingdoms period. It was called Eastern Wu because it occupied most of eastern China in the Three Kingdoms period, and Sun Wu because the family name of its rulers was Sun.

The jiedushi or jiedu was a regional military governor in imperial China. The title was established in the Tang dynasty and abolished in the Yuan dynasty. The post of jiedushi has been translated as "military commissioner" or "governor", "legate", and "regional commander". Originally introduced in AD 711 to counter external threats, the jiedushi were posts authorized with the supervision of a defense command often encompassing several prefectures, the ability to maintain their own armies, collect taxes and promote and appoint subordinates.

Powerful jiedushi warlords eventually became fanzhen rulers, able to override the power of the central government of Tang. An early example of this was An Lushan, who was appointed jiedushi of three regions, which he used to start the An Lushan Rebellion that abruptly ended the golden age of the Tang dynasty. Even after the difficult suppression of that rebellion, some jiedushi such as the Three Fanzhen of Hebei were allowed to retain their powers due to the weakened state of the court. The jiedushi were one of the primary factors which contributed to the political division of the Five Dynasties and Ten Kingdoms period, a period marked by continuous infighting among rival kingdoms, dynasties, and regional regimes established by the jiedushi.

Guo Zongxun (Chinese: 郭宗訓) (14 September 953 – 973) or Chai Zongxun (Chinese: 柴宗訓), also known by his posthumous name as the Emperor Gong of Later Zhou (Chinese: 後周恭帝), was the third and last emperor of the Chinese Later Zhou dynasty, during the Five Dynasties and Ten Kingdoms period. He reigned from July 959, when he succeeded his father Chai Rong (Emperor Shizong of Zhou), until February 960, when he was overthrown by his general Zhao Kuangyin (Emperor Taizu of Song), who founded the Song dynasty.

The Emperor Gong was sent away with his mother to Xijing (西京). Despite assurance by the Emperor Taizu of Song that the Chai family would be treated with respect, the Emperor Gong was killed in 973 by Xin Wenyue, an official trying to gain favour with the emperor. Upon hearing the news, the Emperor Taizu ordered a period of mourning and buried the dethroned emperor next to the Emperor Shizong's tomb.
